The collected information is used solely for the following purposes:

4. Information Sharing

The App does not share any personal information or workout data with third parties. All data is stored exclusively on your device.

5. Data Retention

All data is stored on your device until you uninstall the app or manually delete it.

This information is used to display personalized ads and measure advertising effectiveness. For more details, please refer to Google's Privacy Policy.

On devices running iOS 14.5 or later, App Tracking Transparency (ATT) will prompt you to allow tracking. Even if you do not allow tracking, you can still use the app normally, but the ads displayed may not be personalized.

8. Children's Privacy

The App is not directed to children under 13 years of age and we do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided us with information, please contact us using the form below and we will take steps to delete it.

9. Your Rights (California / CCPA)

If you are a California resident, you have the right to know what personal information we collect, to request deletion of that information, and to opt out of the sale or sharing of personal information. Because the App stores workout data only on your device and does not transmit it to our servers, we have no personal information to disclose, delete, or sell on your behalf — except for the limited advertising identifiers handled by Google AdMob as described in Section 7. To exercise any rights under the CCPA, please contact us via the form below.
