No accounts. No cloud. No tracking pixels. Just you.

No sign-up No analytics No advertising No subscriptions No social feed No notifications
— Quietly built, for the kind of teenager who'd rather not be tracked.
Three things, done well

What's in. What's not.

A tracker should track. Nothing else. We removed every feature that wasn't strictly necessary to log a period and predict the next one.

100% offline-first.

Your data is stored locally on your device. No cloud sync, no servers, no backups we can read. If your phone is off, your data is off.

Works in airplane mode

Zero bloat.

No social feeds. No habit streaks. No notifications nudging you back. Open it when you need it, close it when you don't.

One tap to log. Three screens, total.

Privacy by design.

No account to make, no email to give, no ID to verify. The app doesn't ask for what it doesn't need — which is essentially everything.

One tap to log

Logging a day takes a single tap.

What people actually say.

Reviews are sourced from the App Store and our beta program. We don't request reviews and we don't run ads.

Finally, a tracker that doesn't ask for my email, my location, or try to sell me a subscription. Just a clean, local log.

I wanted something simple and private for my daughter. No accounts, no cloud sync, no tracking. This is exactly what we were looking for.

The interface is incredibly peaceful. No social feeds, no notifications pushing articles — just pure utility.
