"No account. No ads. Your cycle data stays on your phone."

A period tracker that doesn’t need your email

Another period tracker? Yes. Because a cycle log is some of the most personal information on your phone, and we think it should stay there.

No account, no email

You don’t sign up for anything. Open the app and start logging. There’s no email address to hand over, no password to forget, and no account sitting on a server somewhere.

Your data stays on your phone

Your cycle data is stored on your phone and only on your phone. It isn’t sent to a server, it isn’t synced, and it isn’t shared with third parties. That also means there’s no cloud backup — in this case, we consider that a feature.

No ads

The app has no ads. Nothing in it exists to learn about you and sell that to someone else.

What’s free

  • Logging periods, flow strength and notes
  • A calendar with predicted periods and fertile windows
  • Reminders for your period and fertile window

What the optional unlock adds

There’s no subscription. A one-time unlock adds a few extras for people who want them:

  • App lock with Face ID or a passcode, so the app stays private even if someone else picks up your phone
  • A longer forecast of upcoming cycles
  • A doctor-visit export of your history to take to an appointment — and you choose whether your notes are included
No account. No ads. Your cycle data stays on your phone.

A note on predictions

Predictions are estimates based on the cycles you’ve logged, and cycles vary. Please don’t rely on them to plan or avoid pregnancy, and talk to your doctor about anything that worries you.
