Your workout history and preferences are stored locally on your device and synced to Cloudflare D1 (encrypted at rest) when you're signed in. Data is processed in Cloudflare's edge network.

We do not sell, rent, or share your personal data with third parties. RevenueCat processes subscription status only. No other third-party services receive your data.
