How Niyora is different, and what the others do with your data
Most cycle apps are trackers. They find the pattern and hand it back to you. Niyora tracks and predicts too, then walks you through the hard hour when it lands.
The data table
What 9 cycle apps say they do with your data
Not my opinion of them. What each one told Apple, and what each one wrote in its own privacy policy, side by side with a link to every source. 7 of 9 declare data that may track you across other companies' apps. One says deletion reaches data it already shared.

The short version, app by app.
The honest pitch
Niyora has no account, keeps your writing encrypted on your phone, and shows you the evidence behind every claim it makes. Including the weak evidence.
