Cookie Policy

What Are Cookies?

Cookies are small files a website stores in your browser. We also use related technologies — local storage, session storage, and IndexedDB — to keep the app working between visits. This policy uses "cookies" to refer to all of them.

Essential Cookies

We use essential storage to:

• Keep you signed in (authentication session token).
• Remember your theme preference (light or dark).
• Hold your unlocked vault key for the current session only.
• Cache cycle, symptom, and calculator data on your device for offline use.
• Persist your Local-only mode and other privacy preferences.

These are required for the app to function. Disabling them will sign you out and prevent CycleLife from loading.

Analytics Cookies

None. We do not use Google Analytics, Mixpanel, Segment, Amplitude, Hotjar, FullStory, or any other analytics or session-replay vendor.

Managing Cookies

You can clear cookies and site storage at any time from your browser settings. Inside CycleLife, Settings → Privacy → "Erase this device" clears all locally stored entries and caches in one click.

No Advertising Cookies

CycleLife displays no ads and runs no advertising or remarketing tags. We do not sell, share, or rent any data that could be used for advertising.
