Privacy

Private by default. Clear when data leaves your device.

GainScan stores your fitness history locally and sends only the data needed to provide a feature you choose.

Stored on your device

Workout logs, goals, settings, saved progress photos, and scan reports stay local by default. GainScan has no user accounts or cloud photo library.

Sent for a scan you start

A Pro scan sends a compressed copy of your selected photo and limited request settings through GainScan’s stateless proxy to an AI provider. The proxy does not store the photo.

Services that run the app

Apple and RevenueCat handle purchases and entitlement status. AppsFlyer processes limited app-event and device-attribution data for analytics. GainScan does not sell personal information.

Privacy policy

How GainScan handles data

This policy applies to the GainScan app and this website. Data handling depends on the features you use.

  • Local fitness data remains on your device until you delete it, reset local app data, or remove the app.
  • For a scan, the selected image, scan type, requested language, and model setting are processed to return visual-region analysis. Past scans, workout history, reminders, and goals are not included in that request.
  • Scan, hosting, subscription, and attribution providers may process technical request data under their own retention and security practices.
  • Camera and photo-library access is requested only when you choose a photo feature. GainScan does not publish photos or use them for public profiles.
  • Resetting GainScan data removes GainScan-owned local records and photo copies but does not delete original photos from your library or App Store purchase records.
  • If you email support, your email address and message are used to answer your request.
