TrainWeek ("we", "our", or "the app") is a fitness planning tool. This privacy policy explains what data the app handles.
We do not collect, transmit, or store any personal data on our servers. The app does not require an account, and we do not run any backend server.
All information you enter in the app — such as your training plans, workout check-ins, exercise logs (sets, reps, weight), and fitness goals — is stored locally on your device in a local database. This data never leaves your device.
The app does not request access to your location, contacts, photos, camera, microphone, or notifications. The only platform service it uses is:
The app does not integrate any third-party analytics, advertising, or tracking services. No third-party SDK receives your data.
In-app purchase: The app offers an optional one-time in-app purchase (Premium unlock). Payment is processed entirely by the app store — Google Play Billing on Android, the App Store on iOS — which handles your payment information under its own terms. The app itself does not receive or store any payment or card details.
We do not share, sell, or transfer your data to anyone, because your data never leaves your device.
You can delete all your data at any time by uninstalling the app, which removes the local database from your device.
The app is not directed to children under 13, and we do not knowingly collect data from them (indeed, we collect no data at all).
If we ever change this policy, the updated version will be posted at this URL with a new "last updated" date.
