  • Platform, such as iOS or Android
  • Time zone or locale-related information

  • Let you sign in across supported platforms
  • Store and sync your equipment, components, sessions, notes, and photos
  • Calculate component usage and replacement estimates

5. Legal Bases for Processing

Depending on where you live, we process data based on one or more of these legal bases:

  • Contract: to provide the app and subscription features you request
  • Consent: for optional choices such as analytics where consent is required
  • Legitimate interests: to secure, maintain, debug, and improve the app
  • Legal obligations: to comply with applicable laws, store rules, tax, fraud prevention, and platform requirements

6. Photos and Camera Access

If you choose to take or select a photo, HiFiTracker uses that image only to attach it to your equipment or component records.

The app asks for camera or photo library permission only when needed. You can deny or revoke these permissions in your device settings, but photo-related features may not work without them.

7. Data Sharing

We share data only when needed to run the app, provide purchases, comply with law, or protect the service.

Examples include:

  • Storing app data in Firebase
  • Sending subscription identifiers and entitlement information to RevenueCat
  • Receiving purchase status from Apple App Store or Google Play
  • Using sign-in information from Google, Apple, or X/Twitter when you choose those login methods
  • Responding to legal requests where required

We do not sell your data, and we do not use your equipment photos or listening history for advertising.

8. Data Retention

We keep your account and app data while your account is active or as needed to provide the service.

If you delete your account, we delete your HiFiTracker account data and user-created app data from active systems where technically possible.

Some data may remain for a limited time in backups, logs, security records, or third-party systems such as Apple, Google, or RevenueCat where needed for legal, tax, fraud prevention, subscription, dispute, or platform compliance reasons.

9. Account Deletion

You can request deletion of your account and app data from the app's Settings screen.

You may also request deletion at: https://hifitracker.app/account-deletion

You can contact us about deletion at: privacy@hifitracker.app

  • Correct inaccurate data
  • Request deletion
