period Privacy period

The simple period tracker that's private by design!

Cycle data is both personal and very sensitive. While some period trackers make reassuring claims about what they do/don’t do with your data, you can't check how compliant they are.

This app doesn’t send your data anywhere - not to third parties, not to the developer. It stays on your phone (and your personal backups of your phone). You can even check this by using Apple’s Privacy Report function which shows you network activity for your apps. The only network activity you should ever see for this app would be to *.apple.com for in-app purchase activity/verification.

Built around privacy fundamentals such as:
- Data minimization (collect only data you need, no email/account/phone number/name/location is required)
- Client side processing (if you don't need to send it somewhere don't, your cycles data stays on your phone)
- Data portability (let users export and delete their data)
In short, this is a simple app for you to track your cycle, not to track you.
