Does Faye offer AI analysis of my cycle data?
Yes, Faye offers optional AI insights that can analyze your cycle patterns and symptoms to provide personalized recommendations. This feature is completely optional and only happens when you explicitly request it.
Can I back up my data or transfer it to a new device?
Absolutely, it's your data. Faye offers one-click backup of all your data, which you can easily import on another device. This makes switching phones or reinstalling the app completely seamless without losing your tracking history.
How do I know Faye is storing my data on my device and not in the cloud?
Unlike other period tracking apps that are native mobile apps and compiled so you can't see their code or what's happening under the hood, Faye is built on the web. This means you can view its source files, monitor network requests, and verify exactly where your data is stored.
Faye uses IndexedDB, a secure browser database that offers structured data storage and fast data retrieval.
Faye also works offline. You can verify this by opening the calendar page and turning off your internet connection. You'll still be able to log and view all your period data without any restrictions.
