The short version: your data stays on your iPhone. LutAI has no account system and no server. Your cycle, your workouts, your meal plans, and your history are stored only on your device.
All of it is stored locally on your iPhone. We do not operate servers for your data and we cannot see it.
With your permission, LutAI reads your cycle data and workouts from Apple Health to tailor your weekly meal plan. Access is read-only, processed on your device, and never leaves your iPhone. You can revoke access anytime in iOS Settings → Privacy & Security → Health. Health data is never used for advertising and never shared with third parties.
If you connect Strava, LutAI fetches your recent activities (type, duration, date) with read-only access, to plan around your training. Connection tokens are stored securely in the iOS Keychain. Disconnect anytime in Settings → Connections — this revokes access and deletes Strava-sourced workouts from the app.
Purchases are processed by Apple. To validate your subscription, LutAI uses RevenueCat with an anonymous identifier and your Apple-signed purchase receipt. No name, no email, no health data is involved — we never ask for any. Manage or cancel your subscription in iOS Settings → Apple ID → Subscriptions.
LutAI contains no third-party analytics and does not track you across apps or websites. We do not sell data — to anyone, ever. Crash reports, if you opted into Apple's "Share With App Developers" setting, are aggregated and anonymized by Apple.
Settings → Delete account and data wipes everything from your device — cycle data, workouts, plans, history, profile — in seconds. Your subscription is managed by Apple and must be cancelled separately in iOS Settings → Apple ID → Subscriptions.
