Cykie

A private, offline period and cycle tracker for iPhone.

Cykie learns your rhythm from the periods you log and gives you predictions, insights and gentle reminders. There's no account and no cloud: everything you enter stays on your phone.

Common questions

• Where is my data? Only on your phone. Cykie never uploads it anywhere, so the developer can't see it either.
• How do I move to a new phone? In Cykie, open Settings › Export data to save a backup, then use Import data on the new phone.
• Reminders don't appear. Allow notifications for Cykie in your phone's Settings, then use Settings › Send test notification in the app.
• I forgot my PIN. The lock screen offers to erase the data on this phone and start fresh, since there's no account to recover it from. Restore a backup afterwards if you have one.
• Can Cykie be used as contraception? No. Its predictions are estimates and aren't a reliable way to prevent pregnancy.

Privacy
