About a:gain
a:gain is a minimalist fitness app designed to help you build and maintain your workout habits. No complicated features, no social pressure — just you and your fitness journey.
Track your workouts, monitor your progress, and stay motivated with a clean, distraction-free interface that puts your goals first.
Privacy First
We believe your fitness data is personal. That's why a:gain is built with privacy as a core principle:
No Account Required
Use the app immediately without creating an account or signing in
No Tracking
Zero analytics, no usage tracking, no behavior monitoring whatsoever
100% Offline
All your data stays on your device using Apple's SwiftData
No Third Parties
Built entirely with native Swift — no external SDKs or services
Data Collection
We collect absolutely no data. a:gain does not connect to any servers, does not require an internet connection, and stores everything locally on your device.

Delete Your Data
Since all data is stored locally on your device, you have full control:
- To delete specific data, use the delete options within the app
- To delete all data, simply uninstall the app from your device
No request needed — we don't have your data, so there's nothing for us to delete.
