Teen Cycle: Period Tracker

A private period tracker built for teens. No account, no cloud, no ads, no subscriptions. Everything stays on your phone.

TeenCycle is a calm, simple period tracker made for young teens (and anyone who wants less). Log your period in one tap. No sign-up, no email, no questions that are nobody's business. Your data never leaves your device.

STRICTLY OFFLINE
Your data lives only on your phone. No cloud, no sync, no servers, no backups we can read. It works in airplane mode. Delete the app and your data is gone for good. Not even we can see it.

NO ACCOUNT, EVER
No sign-up. No email. No password. No phone number. Open the app and start tracking. We have no way to identify you because we never ask who you are.

ONE TAP TO LOG
Open the app, tap the circle, done. No forms, no follow-up questions. Three screens total: Today, Calendar, and Settings.

SAFE FOR YOUNG TEENS
No invasive questions. No social feed, no comments, no DMs, no profiles, no links out. Nobody outside the app can reach someone inside it, because there is no "outside" inside the app.

ONE FAIR PRICE
Free for 30 days. or ONE-TIME $9.99. No subscription, no renewal, no second charge, ever. No ads, nothing to upsell.

PERIOD PREDICTIONS
TeenCycle estimates your next period from the cycles you log and gets better over time. It isn't a medical tool and doesn't replace a doctor. If something feels off, talk to a healthcare provider.

A WARM DARK MODE
One toggle swaps everything to a soft charcoal theme for late nights. Same calm layout, dimmed for bed.

WHY WE MADE IT
TeenCycle started at a kitchen table. A mom and her daughter went looking for a period app they could trust and couldn't find one. Every app wanted an account, asked too much, or quietly sent the most personal data there is to a server somewhere. So we built the app we wanted, for our own daughter. If it earns a place with yours, it's because it does its job and then leaves her alone.
