E1RM Calculator ("the App") is available on Android and iOS and is designed with your privacy as a priority. This privacy policy explains how we handle information when you use either version of the App.
We do not collect any personal information.
The App performs all calculations locally on your device. We do not:
The App saves your preferences (units of measurement, weight rounding settings) and your purchase status (whether you have supported the developer) to your device's local storage. This data:
All values you enter (weights, reps, RPE) exist only temporarily in memory while the App is running. When you close the App, entered values are cleared.
The App offers an optional one-time in-app purchase ("Support Developer") to support development. Purchases are processed entirely by the platform store:
The developer does not collect, store, or process any payment or billing information. The App only receives confirmation of whether the purchase was completed.
The App does not integrate with any third-party analytics platforms, advertising networks, or data services. The only third-party interaction is the platform's own billing service for the optional in-app purchase described above.
The App does not collect any information from anyone, including children under the age of 13. Since no data is collected or transmitted, the App is safe for users of all ages.
Since the App does not collect, store, or transmit any user data externally, there are no security concerns related to data breaches or unauthorised access to personal information.
We may update this privacy policy from time to time. Any changes will be posted on this page with an updated revision date. We recommend reviewing this page periodically.
If you have any questions about this privacy policy, please contact the developer via GitHub: github.com/gooseyirl.
By using the App, you consent to this privacy policy.
