Privacy policy
Last updated: November 13, 2026
This policy explains what information the Workout Timer app for Android and iOS and this website handle, and how.
1. Controller
The controller of the Workout Timer app and of this website is:
- Company: RearMachine S.L.
- Tax ID (CIF): B86212339
- Address: C/ Secoya 29, 4º-2ª, 28044 Madrid (España)
- Contact: info@rearmachine.com
- Data protection: privacy@rearmachine.com
2. What the app stores
The app does not collect personal data and does not send it to our servers or to third parties. What you create is kept in the app’s private storage, on your device:
- Your timers: names, times, rounds, cycles and colors.
- Volume, alert and sound settings.
- The sounds you record or import and the names you give them.
- The start date of the free trial and whether you bought the full version.
We have no access to that information. It is deleted when you uninstall the app or clear its data in the system settings.
3. Microphone
The app asks for microphone access only to record sound alerts (10 seconds at most) when you tap the record button. The recording is saved on your device with the name you choose and is never sent anywhere.
You can deny or revoke the permission at any time in the system settings; the rest of the app keeps working.
4. Imported audio files
If you import an audio file, the app only accesses the file you pick in the system picker and keeps a copy inside the app so it can be used as an alert.
5. Free trial and purchases
The full version is unlocked with a one-time in-app purchase. The purchase, payment and billing are handled by Google Play (Android) or the App Store (iOS) with your account, under their own privacy policies.
We never receive your payment or account details: the app only asks the store whether the purchase has been made in order to unlock the features. On iPhone, the free trial is activated with a free App Store purchase.
6. System backups
If system backups are turned on (Google backup on Android or iCloud on iPhone), the system may include the app’s data in your backup. That backup is managed by Google or Apple according to your settings.
7. Permissions used by the app
- Microphone: to record your sound alerts.
- Vibration: to alert you with vibration during workouts (Android).
- Google Play billing: to make and check the purchase of the full version (Android).
8. Children
The app does not collect personal data from anyone, including children.
9. This website
This website uses no cookies, no analytics and no ads, and loads no third-party resources: fonts and images are served from our own server.
Like any website, the hosting server may log technical data about visits, such as the IP address or the browser, for security and operational purposes.
10. Your rights
You can exercise your rights of access, rectification, erasure, objection, restriction of processing and portability by writing to privacy@rearmachine.com. As the app does not send personal data to our servers, we will usually hold no data about you.
If you believe we have not handled your request properly, you can lodge a complaint with your data protection authority (in Spain, the Agencia Española de Protección de Datos).
11. Changes to this policy
If we change this policy, we will publish the new version on this page with its update date.
