The short version: Watt Key does not collect, store, or transmit any personal data to external servers. All communication happens directly between your Wear OS watch and your Tesla over Bluetooth, entirely on your device.
This Privacy Policy explains how Watt Key ("the App"), developed by Joshua Henderson ("we", "us", "our"), handles information when you use the Watt Key Wear OS application. We are committed to protecting your privacy and being transparent about our data practices.
By using the App, you agree to the practices described in this policy.
Watt Key does not collect, transmit, or store any personal information on external servers. The App operates entirely on your Wear OS device.
The App stores the following information locally on your device only:
This data never leaves your device and is only used to operate the App's features.
Watt Key requires Bluetooth Low Energy (BLE) access to communicate directly with your Tesla vehicle. The App uses Bluetooth solely to:
Bluetooth communication occurs exclusively between your watch and your vehicle. No Bluetooth data is transmitted to us or any third party.
The App requests the following device permissions:
The App integrates the following third-party services, each subject to Google's Privacy Policy:
Neither service is used for advertising, and neither collects data that personally identifies you. You can learn more at the Firebase Privacy and Security page.
The App is also distributed via Google Play. Google may collect information as part of distributing and operating the App, subject to Google's Privacy Policy.
This website (teslawatchapp.com) uses Google Analytics to understand visitor traffic. Google Analytics may collect anonymous usage data such as page views and browser type. You can opt out using the Google Analytics Opt-out Browser Add-on.
Because Watt Key does not transmit personal data to external servers, there is no server-side data storage to secure. All data retained by the App (preferences and vehicle identifiers) is stored on-device within the standard Wear OS application sandbox, protected by the security measures of your device.
Watt Key is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided information through the App, please contact us and we will take appropriate action.
We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page. We encourage you to review this policy periodically. Continued use of the App after any changes constitutes your acceptance of the updated policy.
If you have any questions or concerns about this Privacy Policy or the App's data practices, please contact us at:
