FST Privacy Policy
1. Information We Process
- Account information: Tesla user identifier, display name, email and internal FST user identifier.
- Vehicle information: vehicle identifier, VIN, vehicle name, online status, battery level, climate status, and cabin and outdoor temperatures.
- Historical high-beam observations: the temporary observation feature has stopped and no longer collects new data. Previously collected start/end times and weather summaries from explicit participation remain viewable for the existing retention period. These records contain no precise coordinates.
- Sensitive personal information: with your separate consent, vehicle location, phone location and phone motion are processed to obtain local weather, calculate target temperatures and identify the current driver. Only if you separately enable approach-based preconditioning are they used to determine whether your phone is continuously approaching a stationary vehicle. The public app does not provide destination navigation. Raw phone location is not stored in the database; only short-lived distance, approach trends and decision states are retained.
- Preferences and records: target temperature, feels-like temperature, preferences formed from manual adjustments or continued acceptance of an FST-set temperature in the vehicle, and control results.
- Subscription information: product identifier, subscription status, expiry time, and encrypted or hashed transaction identifiers.
- Security logs: request time, outcome, random request identifiers and necessary network security logs. We do not use this information for advertising.
2. Purposes and Methods of Processing
We process information only to connect your Tesla account, identify authorized vehicles, obtain local weather, calculate target temperatures, perform climate control you enable, provide history and subscription services, and secure accounts and systems. Processing includes collection, encrypted storage, queries, computation, transmission and scheduled deletion.
3. Separate Consent for Location and Motion
Vehicle location, phone location, phone motion and any resulting movement history are sensitive personal information. Only after separate consent does FST use vehicle location for weather, and phone-to-vehicle distance and automotive motion to identify the current driver, avoiding learning or changing another person's climate habits. Approach-based preconditioning is off by default. Only after you enable it in vehicle settings and grant background location permission does FST check whether your phone is continuously approaching a stationary, unoccupied vehicle and start climate after confirmation. Climate turns off after 10 minutes if nobody enters. The server never stores raw phone coordinates; it briefly retains distance, sample counts, approach trends and trigger state. These are not disclosed to other users or used for advertising. Disable the feature or withdraw consent in Profile → Privacy and Data at any time. FST immediately stops the feature and subsequent location and motion processing when consent is withdrawn.
4. Third Parties and Entrusted Processing
We send authorization and vehicle control requests to Tesla's China API. When weather is enabled, QWeather receives approximate coordinates needed for the query. Tencent Cloud servers in mainland China host FST data. Apple handles subscriptions. See the names, information types and purposes in the third-party list. We do not sell personal information.
5. Retention Periods
- After the paid period ends, FST provides 7 days (168 hours) of continuous service grace. Apple renewal transactions or re-verification in the app update the service deadline. If no new expiry is available when grace ends, Tesla credentials, vehicle identifiers and associations, location/time rules, climate records and learned preferences are automatically cleared. Accounts that have not reached the service deadline are not cleared merely for not using FST.
- Climate records are retained for up to 365 days while the subscription is active.
- Historical high-beam observations are retained for up to 365 days. Stopping collection does not change their existing deletion deadline.
- Security audit logs are retained for up to 180 days.
- De-identified consent and withdrawal records are retained for up to 1095 days to demonstrate compliance obligations.
- Tesla credentials are also cleared when you disconnect Tesla or delete your account.
- Encrypted backups rotate over 14 days. Deleted data is not restored for routine use; restoration reapplies the deletion ledger to remove it again.
6. Security
Sensitive identity data, vehicle identifiers and Tesla credentials are encrypted at rest. FST session tokens are protected by hashing or the system keychain. Transmission uses HTTPS. Access controls, log auditing and encrypted backups protect the service. No measure guarantees absolute security. We respond to and notify you of incidents that may harm your rights as required by law.
7. Your Rights
In the app, view and export personal data, correct information, withdraw location consent, disconnect Tesla and delete your account. You may also email gantzx@icloud.com to request access, copying, correction, deletion, withdrawal of consent or to complain. We verify your identity and handle requests as required by law.
8. Minors
FST is intended for adults authorized to use a Tesla account and vehicle. We do not actively provide service to children under 14. If you discover processing of a minor's information without guardian consent, contact us for deletion.
9. Cross-Border Processing
FST's core servers and Tesla China API are in mainland China. Apple may process subscriptions and App Store services under its own rules. If we later need to transfer personal information outside mainland China, we will separately inform you, obtain separate consent and complete the required procedures under applicable law.
10. Updates
If processing purposes, methods or information categories change materially, we will provide a prominent notice and obtain consent again where required by law.
