Data stored on your device

The app stores the exercises, training plans, workout sessions, sets, rest timers, and preferences you enter in local app storage. The app has no account system and does not send this training data to our servers. We do not integrate advertising, analytics, or crash-reporting services in this release.

Google Play purchases

Advanced analysis and training tools can be unlocked with an optional one-time purchase through Google Play. The app uses the Google Play Billing Library to query product prices and purchase status, start purchases, restore access, and acknowledge completed purchases. Google Play processes transactions using your Google account and payment settings under its own terms and privacy policy. We do not receive your full payment-card details. The app stores an access flag locally; purchase access is not part of exported training backups. We do not send your training records to Google Play or to our servers as part of purchase processing.

Backups and files

When you choose to export a JSON backup, CSV, or text file, the app writes the selected training information to the location you choose through the Android system file picker. Import reads only the backup file you select. The app does not request broad access to your photos or storage. Exported files may contain personal training information; you control where they are stored and whether they are shared. A document provider you choose may store files in its own cloud service under its own terms.

Notifications

With your permission, the app schedules local rest-completion notifications. Notification permission is optional; the foreground timer remains available if permission is denied. Android may delay non-exact reminders. You can disable reminders in the app or revoke notification permission in Android settings.

External apps and clipboard

Rate app opens your device's app-store handler. Contact us opens your email app with our address and a localized subject; we receive only information you choose to send. If no email app can open, you can explicitly copy our email address to the clipboard. The app does not read clipboard contents. External app stores, email apps, and document providers apply their own privacy policies.

Retention and deletion

Training data remains in app storage until you delete the relevant records, clear app storage in Android settings, or uninstall the app. Exported files remain in the selected location until you delete them separately. Android device backup or transfer may retain app data according to your device settings. If you contact us by email, we use that correspondence to respond and resolve the issue; you can request deletion by contacting the address below, subject to any necessary legal retention.

Children and policy changes

The app is not specifically directed to children, and we do not knowingly collect children's personal information. We may update this policy when app behavior changes and will display the updated version and effective date in the app.
