TeLog · Wenling Xinhe Yijia Software Development Studio (sole proprietorship)
Privacy Policy
Effective: 1 September 2026 · Last revised: 16 September 2026 · Version 2.6.3 (canonical https://www.telog.cn/legal/en/privacy.html)
This Privacy Policy applies to TeLog (App Store name may appear as「特档案TeLog」) distributed via Apple App Store and related minimal backend services. The product operator and personal-information handler is Wenling Xinhe Yijia Software Development Studio (sole proprietorship) (温岭市新河壹嘉软件开发工作室（个体工商户）；not Tesla, not Apple). The App is listed on the App Store under an Apple Developer Program Individual membership; that Individual account holder is the same natural person as the sole proprietor of the Studio. TeLog is designed for Tesla owners in mainland China. Even if listed in overseas App Store territories, personal-information practices, notice-and-consent, and disputes follow the laws of mainland China (including PIPL) and this Policy, unless mandatory local law provides otherwise. By agreeing, signing in, or continuing to use TeLog, you acknowledge this Policy. It works together with the Terms of Use (EULA).
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
- Official Tesla path only: Vehicle data comes from Tesla’s official OAuth / Fleet API after you authorize the App. We do not collect or store your Tesla password.
- On-device by default: Telemetry, drives, charges, and tracks are stored in an encrypted local database on your phone unless you separately opt in to cloud features.
- Optional cloud needs separate consent: Cloud collection, backup/sync, and in-app family sharing require additional express consent.
- No ad tracking: No advertising SDKs, no sale of personal information, no cross-app tracking inside the App.
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.
| Step | What happens | Vehicle telemetry via TeLog servers? |
|---|---|---|
| Developer registration | Operator obtains Fleet API credentials | — |
| Owner authorization | You sign in on Tesla’s official auth page (typically auth.tesla.cn) | No |
| Token exchange | HTTPS token proxy exchanges codes/refresh tokens; client_secret stays server-side | Tokens only — no telemetry |
| Vehicle fetch | App calls Tesla Fleet API directly | No (default) |
| On-device processing | Parsing, drives/charges, stats on your device | No |
| Optional cloud collection | Only with separate consent + Cloud entitlement; encrypted copies in mainland China | Yes (optional) |
4.1 Typical OAuth scopes (as shown on Tesla’s page)
openid,offline_access,user_datavehicle_device_data,vehicle_locationvehicle_cmds/vehicle_charging_cmdsonly when you use commands
Examples of derived data: VIN, status, GPS/tracks, SOC, charging metrics, OTA, doors/locks, climate; official vehicle_config trim signals (Fleet Telemetry Trim / trim_badging, CarType / car_type, optional has_ludicrous_mode) used only on-device to prefill DamageLens configuration (you may override). That extra read is one-shot and is not on the regular poll. Also content you create (geofence names, notes, rates, feedback).
5. Information we process
| Category | Examples | Uploaded to our servers by default? |
|---|---|---|
| Account / IDs | Tesla OAuth IDs, local device/archive IDs, Cloud status (Apple) | Token proxy only; billing with Apple |
| Vehicle & trips | VIN, drives, tracks, charges, energy; official trim identifiers used to prefill DamageLens config (overridable) | No (on-device) |
| Precise location | GPS, geofences, reverse-geocoded addresses | No; coords may go to map providers |
| User-entered | Notes, rates, expense fields, feedback email content/screenshots; alert codes / on-screen warning text you type for vehicle-alert lookup | No (email only if you send it; on-device lookup stays local) |
| Vehicle-alert lookup (on-device library) | Preloaded alert codes and messages; UI defaults to the current authorized vehicle (switch via My Vehicles); query card does not show raw handling advice | No (free; query text stays on device) |
| Alert-photo text recognition (when you start it) | One photo you take or pick of the car’s alert screen; on-device Vision OCR for lookup | No — photo is not uploaded |
| Vehicle-alert AI explain (Cloud, when you start it) | Confirmed library fields (code, warning, meaning, basic advice) plus your follow-up; AI rewrites language only — not a diagnostic system | Transient processing via TeLog China servers to Tongyi text models; skipped if the library has no usable facts; no ads/sale; no photos |
| Damage VIN photo OCR (when you start it) | One plate/document photo; on-device Vision reads the 17-character VIN into the estimate form | No — that photo is not uploaded |
| Damage estimate photos (when you start it) | Selected close-ups of damage plus model fields needed for analysis. Results may include a flood/water inspection checklist for reference, and you may save a damage/accident record to the on-device vehicle archive | Transient forward to Tongyi vision via TeLog China servers |
| APNs device token (cloud collection on) | iOS token used to silently wake the App and merge gap-fill (e.g. today’s mileage while the phone is locked) | Only after separate cloud-collection consent; not an ad identifier |
| Optional cloud copies | Drives/tracks/charges/state/geofences for gap-fill & backup | Only after separate consent, in China |
| Family sharing | Invitee IDs and granted scopes | When that feature is enabled |
| Tesla latest-info policy (OTA / sales / after-sales copy) | Public excerpts delivered by TeLog servers and cached on-device; no VIN, drives, tracks, or telemetry in this payload | Public copy only — does not upload your vehicle archive |
| Financing calculator (when you tap it) | Car Assistant opens Tesla China’s official page https://www.tesla.cn/financing-calculator | No — tesla.cn handles the form; TeLog does not receive financing applications |
| Support | Logs/screenshots/versions you voluntarily send | Support tickets only |
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 latest-info 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 latest-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 latest-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; least-privilege scopes; 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
- This Policy describes reasonable efforts. Tesla/Apple/Amap changes, outages, or force majeure may affect service; to the fullest extent permitted by law, the Operator is not liable for all resulting harm, while remaining available to help where feasible.
- Health/value/driving/energy estimates, vehicle-alert lookup/AI explain, and DamageLens estimates (including any flood checklist) are informational only — not official diagnosis, warranty, free replacement, repair orders, or insurance appraisal.
- Tesla latest-info policy excerpts may lag tesla.cn and are not Tesla purchase offers or financing approvals.
- On-device software-update history no longer shows a calendar date: TeLog only sees the first observed
car_versionchange, not Tesla’s official install day. - On-device default means unrecovered loss if the device is lost/damaged without backup—export important archives yourself.
- If you have only ever used the free tier and never subscribed to Cloud, liability limits in the Terms apply: no liability to the maximum extent permitted by law (except non-excludable liability).
- Subscriber monetary caps, notice-and-cure (email + 15 business days), force majeure, and China approval/distribution delay carve-outs are in Terms §11.
- Not formal legal advice. Conflicts with the Terms are resolved by those specific terms.
- Nothing excludes liability that cannot be excluded by law (e.g., willful misconduct or gross negligence causing personal injury).
