Privacy Policy

1. Operator & scope

• Product: TeLog · Bundle ID com.jchen.Telog
• App Store listing account: Apple Developer Program (Individual); the seller/developer name shown on the App Store follows that Individual account
• Operator / personal-information handler: Wenling Xinhe Yijia Software Development Studio (sole proprietorship). Responsible for product operation, user support, and PIPL-related obligations under this Policy
• Identity alignment: The Individual Apple Developer account holder and the sole proprietor of the Studio are the same natural person. Under Chinese law a sole proprietorship is borne by its proprietor; this does not change that the Studio is the operator and personal-information handler
• Contact: service@telog.cn
• Governing approach: Product and compliance baseline is mainland China; overseas availability does not change the China-law-first approach of this Policy (subject to mandatory local laws).
• No affiliation: Not an official Tesla or Apple product; no endorsement.

2. Core principles

3. China compliance & App Store standards

• Lawful, legitimate, and necessary processing only.
• Notice and consent: first launch shows a Terms & Privacy confirmation that must be accepted to continue; separate consent for sensitive / cloud / sharing features; withdrawable. The in-app summary does not replace these online documents.
• Purpose limitation — no ad profiling for vehicle data.
• In-app export, wipe, stop-cloud-and-delete-remote, and Send Feedback / email channels.
• App Store Privacy Nutrition Labels will stay consistent with this Policy.
• Account/data deletion path via Privacy & Data settings and email.

4. How vehicle data is obtained

TeLog uses a third-party app registered on Tesla’s China developer platform (developer.tesla.cn and reads vehicle data only after your authorization.

4.1 Typical OAuth scopes (as shown on Tesla’s page)

• openid, offline_access, user_data
• vehicle_device_data, vehicle_location
• vehicle_cmds / vehicle_charging_cmds only when you use commands

5. Information we process

We do not collect Tesla passwords, Contacts, the full Photos library (only a single photo you pick for damage close-ups, VIN plate OCR, or alert OCR), biometrics templates, or card numbers (Apple handles payment).

6. Purposes & legal bases

Core archive features; on-device vehicle-alert lookup (current authorized vehicle; optional on-device OCR); Cloud-only vehicle-alert AI rewrite/follow-up (text only, after usable local-library facts — not a diagnostic system; no free-replacement or official-warranty promises); Nearby charging (authorized vehicle location via Tesla Fleet API); Vehicle feature toolbox (model/year manuals excerpts + optional Tongyi text guidance you initiate; guide quota separate from DamageLens and alert AI); damage-estimate vision analysis when you start it, with optional official-trim prefill you may override, on-device VIN OCR, and optional flood-inspection checklist; maps; optional cloud fill-in (including location snapshots used on-device to complete an open drive trail), silent APNs wake, and backup; family sharing; Cloud entitlement checks; customer support; security/compliance. Marketing unrelated to these purposes and sale of personal information are not practiced. Under PIPL, bases include consent, contract performance, and statutory obligations as applicable.

7. On-device by default & optional cloud

Default: encrypted local DB on your device. Uninstall/wipe/device backup deletion removes local data.

Optional cloud (Cloud membership): requires Cloud Collection Disclosure consent; used for continuous logging, sync, backup, and silent APNs wake so gap-fill (including today’s mileage) can merge while the phone is locked; not for ads; you may stop and delete remote copies and the device token anytime.

Retention: local until you delete; alert photos used only on-device for OCR; alert-AI and damage-estimate payloads are transient on China servers; cloud copies (if enabled) in mainland China, typically rolling ~365 days, deleted when cloud is turned off; support email generally ≤24 months unless law requires longer.

8. Maps & location services

For lawful maps and reverse geocoding in mainland China, TeLog may use Amap (Gaode) Open Platform with keys obtained by the operator. Coordinates and render params may be sent to Amap; Tesla passwords/tokens are not. Optional OSM Nominatim fallback may be used when allowed and Amap is unavailable.

9. Third parties

Tesla (Fleet API); Apple (App Store / StoreKit / APNs silent wake when cloud collection is on); Amap; China-region cloud hosts for token proxy, optional vault, damage-estimate vision, vehicle-alert text AI, and vehicle-feature-toolbox text guidance; Alibaba Cloud Tongyi / DashScope (vision for damage photos you submit; text for alert explain you start — isolated requests; API keys stay on the server); optional OSM Nominatim; tesla.cn public pages when you open a info-policy link or the Car Assistant financing calculator (that card opens only https://www.tesla.cn/financing-calculator). We do not sell or rent your personal information beyond those uses and legal requirements.

Vehicle-alert lookup vs AI: on-device library search is free and stays local (defaults to the current authorized vehicle). Photo OCR is on-device and does not upload the image. AI explain/follow-up is Cloud-only: the on-device library is the fact source; AI only rewrites language and must not invent causes or parts. It requires usable library meaning/advice first (otherwise no model call) and sends text only. Independent of DamageLens vision analysis. All AI outputs are informational — not Tesla official diagnosis or repair instructions.

Tesla info policy / financing calculator: both are free. OTA, sales, and after-sales excerpts are compiled from public sources, delivered by TeLog servers, and cached on-device so a later visit can show the last copy while refreshing in the background. This path does not upload VIN, drives, or telemetry. The copy is not an official Tesla App promise. After you tap an outbound tesla.cn link you leave TeLog and Tesla’s site rules apply. The financing card opens only the calculator URL above; TeLog does not fill or receive loan applications.

10. Cloud membership & Apple payments

Cloud membership (IDs typically com.jchen.Telog.plus.monthly / com.jchen.Telog.plus.yearly; also called TeLog Plus / Cloud) is billed by Apple. We do not collect card numbers. Refunds/invoices follow Apple.

Free examples: live status, emergency tools, vehicle-alert lookup (on-device library, optional on-device photo OCR), VIN/tires, recent drives/charges, basic stats, standard share cards, OTA history, TOU electricity settings, maintenance checklist, vehicle digital passport (on-device viewing), geofence management, expense reports (5 free exports), DamageLens (limited monthly quota; official Tesla trim may prefill configuration and remains overridable), road-trip logbook (check-ins, no subscription), Tesla info policy (server-delivered public excerpts), financing calculator (opens tesla.cn only), Nearby charging (Charges tab; Tesla Fleet location lookup; no Cloud required), Vehicle feature toolbox (feature lookup + AI guidance with a free monthly guide quota; Tongyi AI server required for AI calls). Cloud examples: always-on smart logging and silent sync while locked (today’s mileage), full history, analytics dashboards (you may open the hub directory first; tapping a specific panel requires Cloud), battery health/value, vehicle health index, attribution & driving reports, passport PDF export and optional cloud backup, vehicle-alert AI explain and follow-up, family share, unlimited expense reports, parking stats, sync/backup, PDF/Excel, premium share templates, higher DamageLens quota, higher Vehicle feature toolbox AI-guidance quota (e.g. ~100/mo or ~1200/yr; App display controls). App screens and App Store listing control.

11. Your rights

Under PIPL (and mandatory local law where applicable): access/copy, correction, deletion, withdraw consent, stop use, complain to authorities. Use Settings → Privacy & Data, or email service@telog.cn with subject “Privacy request”. We aim to respond within 15 business days.

12. Children

TeLog is for adult owners/managers. We do not knowingly collect personal information from children under 14. Guardians may contact us to delete mistaken collections.

13. Security

On-device encryption and device lock; client_secret not in the binary; HTTPS; encrypted cloud vault when enabled; scopes limited to each feature; incident notice and remediation as required by law. No system is perfectly secure—protect your device and Apple ID.

14. Cross-border notes

• Default processing stays on your device.
• Optional cloud stores in mainland China after separate consent.
• Tesla/Apple interfaces, optional overseas reverse-geocoding fallback, or emails you send abroad may involve cross-border paths you choose or that third parties operate.
• We do not, by default business design, provide identifiable vehicle-archive copies overseas without required assessment/consent.

15. Updates

We may update this Policy and post a new effective date. Material changes will be surfaced in-app or prominently. Continued use after updates means acceptance; otherwise stop using and delete data.

16. Contact

17. Operator disclaimer

Tesla dashcam clips, added 3 November 2026 (App 2.0.2)

This section only adds how Tesla dashcam clips and the driving-data report handle information. It does not replace or delete the clauses above, and it does not change vehicle commands, subscription products, Life features, or the existing handling of other vehicle data.

• Where processing occurs: Open the Stats tab. After you choose one video, parsing is completed on your device. The video, the parsed result, and the PDF generated from it remain on the device by default. The operator does not receive, upload, or store that video, result, or PDF.
• How a file is chosen: You select one file yourself from Photos or a connected storage device. This feature does not scan the other videos in your library.
• Obtaining the video: AirDrop is preferred. Send the original MP4 dashcam clip from the Tesla vehicle’s USB drive to the phone, so the original format and the source file size are kept. When downloading through WeChat, choose the original video. Only that choice keeps the true size of the source file. A file sent from a computer through WeChat and then downloaded to the phone may change format. If the format changes and the source file size stays the same, the app supports it and can parse it. If the source file size is not preserved, parsing is not guaranteed.
• Files that are accepted: Only a dashcam clip from the Tesla vehicle’s original USB drive is accepted. A single original MP4 from the vehicle is preferred. The file must not exceed 81,000,000 bytes (81MB), and the duration must not exceed 61 seconds. A clip on that drive is ordinarily about 60 seconds. A file over that size or duration is not read. Acceptance after a WeChat transfer is stated under “Obtaining the video.”
• Files that are not supported: Composite videos, edited videos, spliced videos, and videos whose file size has changed because of compression or transcoding are not supported. Those files are not guaranteed to parse, and no driving-data report is generated for them. A WeChat download that changes only the file format, while the source file size stays the same, is governed by “Obtaining the video.”
• Design basis: Vehicle-data fields are arranged according to Tesla’s publicly available SeiMetadata data structure and the corresponding field definitions. The parsing program is implemented by TeLog and runs only on the user’s device.
• Location fields: If a clip contains latitude, longitude, or heading, those fields are processed only on the user’s device as part of parsing. They are not shown in the driving-data report or in the interface, and they are not uploaded.
• Report and sharing: After parsing, you may generate a PDF on the device. Export opens a local preview first. You may then share it yourself through the system share sheet. After the file is shared to another app, that app handles it under its own rules. The operator does not handle that share.
• Usage counts: The free-use record and the unlimited-membership state stay on the device and are not uploaded to the operator’s server. The counts are those stated in the Terms added on the same date.

Warranty reminders, added 31 October 2026 (App 2.0.1)

This section only adds how the vehicle warranty reminder and the battery and drive unit warranty reminder handle information. It does not replace or delete the clauses above, and it does not change other Life features, vehicle commands, subscription products, or the existing handling of vehicle data.

The 28 October 2026 statement that Life features do not read vehicle, trip, or charging records does not apply to these two reminders. The other Life features remain as stated on that date.

• Vehicle warranty reminder: Life → Car. You enter the warranty start date. It is not inferred from the VIN or an invoice. When the vehicle is linked, the feature reads the current odometer already stored on this device and applies 4 years or 80,000 km, whichever comes first. That measure is Tesla’s official warranty rule. If Tesla later changes it, Tesla’s then-current official terms and the documents for that vehicle prevail. The date, any optional extended-warranty choice, and the reminder settings stay on the device. When the vehicle is not linked, the odometer is not read. The date and odometer are not uploaded to the operator’s server, and the vehicle record is not changed. Reminders are local notifications.
• Battery and drive unit warranty reminder: Life → Tools. You enter the vehicle delivery date. The high-voltage battery and the drive unit share that date. It is not inferred from the VIN. When the vehicle is linked, the feature reads the official configuration code and the current odometer already stored on this device. Without an official code, the full-charge range already on the device is compared with the built-in rated-range and pack-size references. If the configuration still cannot be confirmed, you may choose it on this page. That choice stays inside this feature and is not written back to the vehicle record. The term is 8 years or 160,000, 192,000, or 240,000 km for the confirmed configuration, whichever comes first. Battery and drive unit reminders are stored separately on the device and are sent as local notifications. They are not uploaded to the operator’s server. The current battery-health figure is calculated and shown on the device only while Cloud membership is active. Without a subscription, only that number is hidden, and no battery data is uploaded for that reason. The rest of the page does not require a subscription. The result is not a Tesla official warranty determination.

Life, added 28 October 2026 (App 2.0.0)

From this date the app adds Life. This section only adds how these features handle information. It does not replace or delete the clauses above. Life features do not read vehicle, trip, or charging records, do not send commands to the vehicle, and do not change existing vehicle features, Cloud vehicle benefits, or the existing vehicle AI allowances.

• On this device, no subscription required: tax calculator, repayment calendar, English practice, driving-test handbook, licence manager, 21-day workout check-in, calendar and holidays, and file conversion, plus step one of the MBTI personality-preference test. The tax result is not filed with a tax authority. The repayment calendar is not a bank. Driving-test and licence tools are not connected to a traffic authority. Files are converted on the device.
• Location: used only while you actively record a workout route. The track stays on the device and is not uploaded as a vehicle location.
• MBTI personality-preference test: step one is 93 questions, free, and stays on the device. Step two uses this app’s own 145 preference items and requires an active Cloud membership. It is not a clinical or medical diagnosis.
• Homework and olympiad practice start only after you turn on Tongyi and send the request yourself. Question images go through the TeLog server in China to Alibaba Tongyi. Only a successful result counts. Homework: 50 successful solves per calendar month free, 150 per calendar month for monthly and yearly Cloud members. Olympiad: 20 successful generation requests per calendar month free, 100 per calendar month for members. Allowances reset each calendar month; there is no yearly pool.
• Checkup readings start only after you turn on Tongyi and send the report yourself. The report you choose goes through the TeLog server in China to Alibaba Tongyi. Only a successful reading counts. Free use is 2 successful readings per calendar month; a valid trial, monthly membership, or yearly membership has unlimited readings. Saving, viewing, and comparing checkup history requires a valid membership. After expiry, access is restricted and saved reports are not deleted automatically. A comparison is not a diagnosis. The operator does not provide medical advice and does not practice medicine. The report is chosen and uploaded by the user. The reading is generated by the Tongyi artificial-intelligence model for the user's personal reference only.

Additions from 18 October 2026 (App 1.1.3) — personal-information notes

The following is available or improved from this date. This section only adds how these items handle information. It does not replace or delete the clauses above.

• Vehicle configuration lookup: The feature is located at Home → Car assistant → Common lookups. It uses only the vehicle identification number (VIN) of the vehicle currently authorized on this device. When the user selects Open parts page, that VIN is included in the request address and is sent from the user’s device directly to parts.tesla.com, in order to open that vehicle’s compressor parts page. Tesla receives that visit. TeLog does not receive the request, and TeLog’s server does not relay the page. When identifying the heat-pump compressor brand, the App reads the compressor part number shown on that page and applies the prefix rule set out below on the user’s device. The part number and the brand identification are displayed only for that viewing and are not uploaded to the operator’s server. The feature may be used only for the current vehicle. After the current vehicle is changed, the parts page and identification result of the previous vehicle are cleared. The applicable models are Model 3, refreshed Model 3, Model Y, refreshed Model Y, and Model YL.
• How the compressor brand is identified: The brand identification is generated by a Telog rule that maps a part-number prefix, compiled from publicly available service documentation. The result does not constitute a Tesla official lookup, an official certification, or confirmation of the part originally fitted to the vehicle. This Policy does not reproduce repair procedures. Prefix 1501256 corresponds to DENSO. Prefix 1582668 corresponds to Sanden. Any other prefix is displayed as not identified. The correspondence is recorded in publicly available Model 3 heat-pump compressor service notes concerning compressor-type configuration. Tesla’s service-manual pages are used to verify the compressor assembly and the part number. After the user selects the relevant link, the page opens in the system browser. TeLog does not download or store the removal and replacement steps contained in those pages:
  • https://service.tesla.com/docs/ModelY/ServiceManual/en-us/GUID-53AA41C0-EC55-403C-BADC-82DCAB9F381E.html (2020–2024 Model Y Service Manual: Compressor (Remove and Replace))
  • https://service.tesla.com/docs/Model3/ServiceManual/en-au/air/GUID-53AA41C0-EC55-403C-BADC-82DCAB9F381E.html (2017–2023 Model 3 Service Manual: Compressor (Heat Pump) (Remove and Replace))
  Sources, applicable models, and accuracy may differ. Production batch, configuration, and subsequent replacement may cause the identification to differ from the actual condition of the vehicle. This feature is provided solely for vehicle-information lookup and reference. It does not constitute advice to purchase, repair, or replace a part. Where actual service or part fitment is concerned, the official service information for that vehicle, a verified part number, or confirmation by a qualified technician shall prevail. Tesla, DENSO, Sanden, and related marks belong to their respective owners. Except where expressly stated, no official authorization, certification, or partnership with those brands shall be understood to arise from this feature.
• Actual fitment and an auxiliary check: Tesla may vary heat-pump compressor fitment between DENSO and Sanden on some vehicles. This feature produces a reference result only from the part number in Tesla’s public parts catalog. Where that result differs from the compressor actually fitted, including where the catalog result is DENSO and the vehicle is fitted with Sanden, the actual fitment prevails. A user who wishes to cross-check may open Cabin Overheat Protection under temperature in the official Tesla app. As of 18 October 2026, a display of 30°C, 35°C, or 40°C on that screen corresponds to DENSO. That correspondence is limited to the official Tesla app display as of 18 October 2026. If Tesla later changes the official display or explanation, Tesla’s then-current official display and explanation prevail. This item does not add a category of personal information.
• Home connection entry: Where a Tesla account has not been connected and this device has not yet stored a vehicle, the home status “Connect your Tesla account first” may be selected to open Connect vehicle. The action opens only the existing authorization screen. It does not read or transmit a vehicle identification number (VIN), and it does not add a category of personal information. After the account has been connected or a vehicle has been stored on the device, that status no longer provides navigation.

From 13 October 2026: limited-time free trial (effective that day)

This section only explains how the limited-time free trial change handles information. It does not replace or delete the clauses above.

• New users: From 13 October 2026, the limited-time free trial for new users no longer states a fixed number of days in this Policy. The trial length is as shown on the App Store subscription page at the time. Apple decides eligibility for that Apple ID. This does not add a category of personal information. When the App Store does not offer an introductory trial, the subscription page does not display a trial.
• Trials already started: A trial that had already started before 13 October 2026 continues under the trial terms that applied when it started. The trial-display terms of 11 October 2026 remain in effect.

Additions from 12 October 2026 (App 1.1.2) — personal-information notes

The following is improved from this date. This section only adds how these items handle information. It does not replace or delete the clauses above.

• Analytics dashboards: The user may open the analytics dashboard directory first. Opening that directory does not add a category of personal information. When the user selects a specific item, the App continues to prompt for a Cloud subscription under the existing terms. Local storage statistics read only the on-device database and are displayed on the device. They do not require a Cloud subscription and do not, by that view, upload vehicle data to the server.
• Cloud collection (24/7): During a valid trial or paid subscription, cloud collection that the user has already enabled continues under the existing terms. While membership remains valid, launching the App alone does not disable it. After the trial or subscription expires, this version turns the switch off, stops uploads from the device under the existing disablement path, and requests that the server stop collection for that vehicle. This does not add a category of personal information. After the user obtains a valid subscription again, the user must enable it again under Settings → Advanced. The cloud-collection terms of 11 October 2026 and earlier remain in effect.
• Membership comparison: The Cloud membership comparison lists Cloud collection (24/7) as a separate item. The free plan does not include it; the Cloud plan does. Analytics dashboards are listed as 20 items and do not include Local storage statistics, which are provided without a subscription. This display does not add a category of personal information.

Additions from 11 October 2026 (App 1.1.1) — personal-information notes

The following is added or improved from this date. This section only adds how these items handle information. It does not replace or delete the clauses above.

• Tesla environmental info sheet: Home → Car assistant → Common lookups. After the vehicle is authorized, tap Current vehicle to fill this phone’s current VIN, or type a 17-character VIN yourself. You type the verification characters from the image. That VIN and those characters are sent once through TeLog’s server in mainland China to retrieve that vehicle’s EV environmental information sheet, which you can open online or download. The values differ by vehicle. The sheet usually has four parts: vehicle information (model, trademark, vehicle class, nameplate location, manufacturer, factory address); inspection information (standard, testing body and result, factory inspection, production conformity); pollution-control information (drive unit, vehicle controller, energy storage, and battery capacity / range); manufacturer information (legal representative, address, telephone, and lookup links). The disclosure number, barcode, and anti-counterfeit code also follow that vehicle. This feature is only for the user to look up their own sheet, and is not used for any other purpose. It is not written into the vehicle passport, not used for marketing or profiling, and not provided to third parties for other uses. It does not read trips or charges and does not change vehicle settings. This feature does not require a subscription.
• Cloud trial length: The membership page shows the trial length from the current App Store introductory offer. When the App Store does not offer an introductory trial, the App subscription page does not display a trial. No new category of personal information. Apple decides eligibility for that Apple ID. Price, auto-renewal, and cancellation stay as already agreed and as shown in the App Store.
• Optional QQ Mail on feedback: Send Feedback adds an optional QQ Mail address. Leaving it blank still sends the mail. If you fill it in, it travels only in the email you send, and is used only to contact you, alongside the existing mobilenumber@139.com path. It does not create a separate cloud profile. The 3 October 2026 terms for VIN, TeLog No., and mobile number still apply.

Additions from 8 October 2026 (App 1.1.0) — personal-information notes

The following is improved from this date. This section only adds how this change handles information. It does not replace or delete the clauses above.

• Tesla Skin (improved): When the authorized vehicle is identified as a Model YL, the skin page is titled Model YL and lists only wraps whose filenames say “适用 Model Y L”. Those wraps are listed apart from ordinary Model Y skins. The Skin clauses of 30 September 2026 and 6 October 2026 still apply.

Additions from 6 October 2026 (App 1.0.9) — personal-information notes

The following is available or improved from this date. This section only adds how these features handle information. It does not replace or delete the clauses above.

• Tesla operating results: Inside Tesla info policy, you can read Tesla’s published production and deliveries, operating progress, and the company’s outlook. Bodies are sent by the TeLog server; category names stay fixed in the App. This feature does not read the VIN, trips, or charges, is not tied to the current vehicle, and does not write the report text into the vehicle file. Disclaimer: content is from published reports, official records, and Tesla’s outlook. For reference only. It is not investment advice, a securities recommendation, a promise of returns, an official Tesla commitment, or an offer to buy a vehicle.
• Official addresses (opened in the system browser. TeLog does not download or store the filing text from those sites):
  • https://ir.tesla.com/sec-filings — Tesla’s investor-relations SEC filing library. The list changes when Tesla updates the page. When this note was written it included the 2 Oct 2026 8-K, 29 Sep 2026 8-K, 9 Sep 2026 Form 4, 8 Sep 2026 Form 144, 22 July 2026 10-Q, 22 July 2026 8-K, Schedule 13G/A, and the SD Specialized Disclosure Report. A filing can usually be opened as SEC HTML or PDF. The live page controls the list.
  • https://www.sec.gov/edgar/browse/?CIK=1318605 — the U.S. Securities and Exchange Commission’s official Tesla filing archive (CIK 1318605). It can be used to look up 10-K annual reports, 10-Q quarterly reports, 8-K current reports, Proxy / DEF 14A (annual meeting, board, and shareholder proposals), insider transactions, and Schedule 13D / 13G large-holder disclosures.
  • https://ir.tesla.com/#quarterly-disclosure — Quarterly Disclosure on Tesla’s investor-relations home page, grouped by year and quarter: Earnings Date, Press Release, Shareholder Deck, Webcast with Q&A, SEC Filing (the related 10-Q / 10-K), Production & Delivery, and Consensus (market-expectation figures shown on Tesla’s page). Consensus is Tesla’s page, not a TeLog forecast, and it is not investment advice.
• Tesla Skin (improved): Skins are matched to the current authorized vehicle’s model and hardware version, and can be saved to Photos. The hardware version comes from vehicle_config.driver_assist in the official Tesla Fleet API vehicle_data response after you authorize the car. Until that field is read, the screen shows HW--. If the car is asleep, TeLog wakes it and then reads; if it is already awake, the field is read directly. After a successful read, the official value is shown in hardware form, for example TeslaAP4 as HW4 and TeslaAP3 as HW3, and saved on this device. The next time you open Tesla Skin, the saved version is shown and the car is not read again. If the first read does not return a value, the label stays HW-- and the next visit tries once more. The value is used to match skins, and is a prerequisite for a later FSD (Supervised) assisted-driving statistics feature. This version does not start assisted-driving mileage statistics.

Additions from 3 October 2026 (App 1.0.8) — personal-information notes

These notes apply from this date. This section adds how the feedback change processes information and does not replace the numbered clauses above.

• App feedback: After Tesla is linked and you are signed in, feedback automatically includes the current vehicle VIN (used only to diagnose App faults) and TeLog No. (used only for cloud diagnosis). You cannot edit them. The message also states whether Cloud membership is active and whether 24/7 cloud collection is on. Phone number is optional; if provided, we may reach you at phone@139.com when email cannot be delivered. These items travel only in the mail you choose to send. They do not create a separate cloud record.
• Reply time (protects the operator): If the user’s mailbox is full or another receiving failure prevents delivery, whether the operator has fulfilled the duty to reply, and the time of that reply, are measured by the time the operator actually sent the message. A failure of the recipient’s mailbox is not treated as a failure to reply, and does not extend the response period.

Additions from 3 October 2026 (App 1.0.7) — personal-information notes

These notes apply from this date. This section adds how the new item processes information and does not replace the numbered clauses above.

• Tesla Automation: An in-car automation reference. It groups steps as arrival and voice, safety, battery and charging, windows, climate, and display, and lists each item’s actions, triggers, and conditions on this device so you can create them yourself on the Tesla car screen. The steps stay on this device. It does not read the VIN, does not upload them, and does not send commands to the car. Free.

Additions from 30 September 2026 (App 1.0.6) — personal-information notes

These notes apply from this date. This section adds how the new items process information and does not replace the numbered clauses above.

• Tesla Skin: Browse wraps for the current authorized model, and search. The catalog is fetched through TeLog’s mainland-China API as short-lived signed image links on skin.telog.cn. This feature does not read trips or charges, does not change vehicle settings, and does not sync a wrap to the car. A photo is saved to this device only when you tap download and save, which needs Photos permission. Tesla Skin is currently open only for Model 3 and Model Y. Model S and Model X skins are not available yet and will wait for a later update.
• Battery charge cycle: This feature gives owner steps by chemistry. The battery management system (BMS) checks state of charge (SOC) from open-circuit voltage (OCV) and brick voltage when the car is resting, current is near zero, or the contactors are open. The voltage–SOC curve carries more information at low SOC. A second check at high SOC reduces bias from calibrating at only one point and helps limit CAC overestimation. LFP has a flatter voltage curve: the daily charge limit is suggested at 100%, with at least one true full charge and a rest each week. Ternary packs do not need full charges as often as LFP: the daily limit is suggested at 80%–90%, with separate rests at low SOC and high SOC. Whether SOC or CAC actually updates is controlled by the vehicle BMS. While you tap Start recording through End this step, TeLog reads only the overview already available and stores it on this device: state of charge, vehicle state, charging state, charge limit, charger power, charger voltage, inside and outside temperature, climate, preconditioning, Sentry, cabin overheat protection, and that step’s start and end time. Records are kept per vehicle and chemistry (LFP or ternary). Switching cars reads that car’s own record. Clear this round deletes only this on-device record. It is not uploaded to the Operator’s servers, does not start or stop charging, does not change the charge limit, and does not wake the car on its own. This feature does not calculate or display battery health, capacity, or a health score, and it does not mean the BMS finished calibration. If the vehicle shows any condition or alert, contact a Tesla service center promptly or call the Tesla hotline at 4009100707. For these steps, Tesla official charging stalls are suggested.
• Maintenance price lookup: In Car assistant, prices are shown for the model you pick. The price list is in the App. It does not read the VIN, is not tied to the current car, and does not use the network. The prices are Tesla’s official quotes. If they differ slightly, the Tesla service center prevails.

Additions from 25 September 2026 (App 1.0.5) — personal-information notes

These notes apply from this date. This section adds how the new items process information and does not replace the numbered clauses above.

• Trips · tire pressure: The Drives tab shows each tire’s pressure on a top-view car image, and stored history by date. Values come from records already collected on-device for the authorized vehicle and stay on-device by default. This does not upload your full vehicle archive to the Operator’s business servers.
• Teslalog Engineer: Answers are based on the authorized vehicle’s on-device data. The processing path, quota, and reference-only nature are unchanged. No new category of information is collected.
• Charge schedule: Charging starts at the time you set. An existing schedule can be edited, and after you save it the car uses the new time. TeLog still reads and writes the schedule with Fleet charging commands. No new category of information is collected.
• Overview while cloud collect is off: Without a subscription and without Cloud collect, the App does not keep requesting vehicle status in the background, so Overview keeps the last driving state. If the car is already parked and the screen still says Driving, tap Wake to sync the current state. That is expected when Cloud collect is off, and it is not a new collection. With Cloud collect on, parking is recorded in the background and Overview updates the next time you open the App. Cloud collect itself remains governed by the Cloud Collect disclosure.

New features from 22 September 2026 (App 1.0.4) — personal-information notes

These capabilities shipped in the App on this date. This section adds how they process information and does not replace the numbered clauses above.

• Lock / unlock: Only after you tap Overview shortcuts, TeLog sends a Tesla Fleet vehicle command (needs vehicle_cmds). Outcomes may be logged in on-device Vehicle activity. This does not upload your full vehicle archive to the Operator’s business servers for cloud storage.
• Charge schedule: When you view, create, or delete schedules, TeLog uses Fleet charging commands (needs vehicle_charging_cmds); creating a schedule may use the vehicle’s current location and may wake the car. Free.
• Charging health, Vehicle activity, long-trip reports, running cost: Derived from on-device drives, charges, passport, and fees you enter; stored on-device by default. Running cost does not auto-include expense-report parking/tolls or DamageLens estimates.
• Insurance details: Compulsory/commercial insurer name, optional policy number, dates, and premium that you enter are stored on-device per vehicle for display and daily amortization into running cost. We do not send this to insurers.
• Recall lookup: After you enter or use the authorized 17-character VIN, TeLog queries Tesla’s official recall API once; results stay on-device. The VIN is used only for that query.
• Teslalog Engineer: When you ask a question, excerpts from on-device drives/charges/parking/vehicle activity are sent via TeLog’s mainland-China server to Alibaba Cloud Tongyi (text). Quota is separate from DamageLens, alert AI, and Feature Toolbox: 10 free uses per calendar month; Cloud 50/mo or 600/yr. Insufficient local data is stated — no invented diagnosis. Answers are reference-only.
