All your cycle data — period dates, mood, energy, and notes — is stored exclusively on your device. EveClock never uploads your personal health data to any server.

Your data is encrypted at rest using Android Keystore (AES-256). Even if someone accesses your phone's storage, your health data cannot be read without your device credentials.

EveClock does not require you to create an account or sign in. A username is only needed if you choose to back up your data to your personal cloud drive.

EveClock contains zero analytics SDKs, no advertising networks, and no third-party tracking. We do not monitor how you use the app.

Your health data is yours. We will never sell, share, or monetize your personal information in any way.

Core cycle tracking is fully offline — your period data, mood, and notes never leave your device automatically. Internet is used only for one opt-in feature:

Google Drive Backup — backs up your encrypted data to your own personal Google Drive account. Only you can access it.

This feature requires your explicit action to activate. You can revoke internet permission at any time in Android Settings without affecting offline tracking.

You can export all your data as a CSV file at any time via Settings → Export Data. You can permanently delete all data via Settings → Reset All Data. Both actions are immediate and irreversible.

EveClock is for informational purposes only. It is not a substitute for professional medical advice, diagnosis, or treatment. Cycle predictions are estimates based on your logged data and may not be accurate. Always consult a qualified healthcare provider for medical concerns.
