2. Scope / Overview

This Privacy Policy applies to the mobile app Ringforge (iOS/Android).

For the website privacy policy, see exerlyze.com Privacy Policy.

Current setup:

  • No user accounts / no login
  • No cloud sync
  • No ads / no retargeting
  • App data (timers/settings) is stored locally on the device.

3. App: local storage

Ringforge currently stores timer/settings data locally on your device. We do not automatically receive this data.

4. Health and fitness data

Ringforge is a training timer app for combat sports (boxing, Muay Thai, etc.). As part of the app's functionality, the following fitness and activity data is collected and stored locally on your device:

  • Workout session data: date and time of the training session, duration, number of completed rounds, completion status
  • Training progress: workout streaks (consecutive training days), total number of completed workouts and rounds
  • Gamification data: earned badges and personal records
  • Timer profiles: individual configurations for preparation, round, and rest intervals

We do not collect any biometric or body-related data (e.g., heart rate, steps, calories, weight, body composition). There is no integration with Apple HealthKit, Google Fit, or Health Connect.

Purpose: tracking personal training progress, motivation through gamification (streaks, badges). Storage: exclusively locally on your device. This data is not transmitted to us or to any third parties. Legal basis: Art. 6(1)(b) GDPR (performance of contract / provision of app functionality). Deletion: you can delete this data at any time by resetting the app data or uninstalling the app.

5. Crash reporting (Firebase Crashlytics)

We use Firebase Crashlytics (Google) to analyze crashes and improve the stability of the app.

In particular, the following data may be processed:

  • crash stack traces / diagnostic data
  • related identifiers (e.g., Crashlytics Installation UUID, Firebase Installation IDs)
  • device/system information (platform-dependent)

Purpose: detecting, diagnosing, and fixing crashes and errors. Legal basis: Art. 6(1)(f) GDPR (legitimate interests in maintaining a stable and secure app). Retention: Crashlytics typically retains these data for 90 days before the deletion process starts.

Note: We do not enable Google Analytics data sharing ("Data Sharing" default settings) unless explicitly activated.

6. Minors

Our service is intended for individuals aged 16 and older. We do not intend to process personal data of children under 16. If we become aware that such data has been processed, we will delete it as required by law.
