Our story.
It started at our kitchen table, not a boardroom. My daughter, Mia, was about to start tracking her period, and the two of us went looking for an app we could trust. Instead we found apps that wanted her email and a login before she’d logged a single day. Apps that asked a young teen questions about her sex life. Apps with feeds to scroll and streaks to keep, quietly sending her most personal information to a server somewhere. For a period tracker.
So we stopped looking and started listing — not what an app could do, but what it should. It should log a day in one tap. It should never ask a young teen a question that isn’t its business. It should keep everything on her phone, where no company — not even us — can see it. And it should cost one fair price, once, with nothing ever trying to sell her anything again.
Mia and I designed that app screen by screen — the warm colors, the two flow states, the single tap to log. My husband is the developer; he built exactly what we asked for, and nothing we didn’t. Every feature had to earn its place by helping log a period or predict the next one. The rest never belonged here in the first place.
We’re not a startup with investors to answer to or data to sell. We’re a family that built the thing we wished existed — for my own daughter first.
If it earns a place on your phone, it’s because it does one quiet job well, and then leaves you alone. The founders are Laura and Mia — first names, on purpose.
“I didn’t want an app that wanted to be my friend. I just needed to know when my period was probably coming.”
— Mia, co-founderWhat we believe.
Our aim is simple: give teenagers a calm, useful, completely private place to understand their cycle — without accounts, ads, or data collection. Four ideas keep us honest.
Calm beats clever
A health app shouldn’t feel like a health app. No streaks, no badges, no noise — just the thing you came for.
One job, done well
Log a period, estimate the next one. Every feature had to earn its place, and most didn’t.
Private by default
Your data lives on your phone, where no company — not even us — can see it. Privacy by architecture, not by policy.
Respect, not advice
We answer the question and step back. We never moralise, and we never gamify a body.
How to use TeenCycle.
The whole app is three screens. Here’s what each one does and how you’d use it day to day.
Log a day in one tap
Open the app, tap the circle, then close it. One tap logs a normal flow, a second logs a lighter day, a third clears it — no forms, no scrolling, nothing to set up. The little strip underneath shows the days around today, and when your period ends you tap “Log period end” to close out the cycle and turn off the daily reminders until the next one.
See your whole cycle
Every day you log shows up here — past days in terracotta, your next date estimated from your own history in a paler clay outline. Tap any day to fill in one you forgot, or swipe between months. Your average cycle length and typical period length sit just below, and they adjust as you log more. Predictions are estimates that get steadier over time, not promises.
Private by design
Flip on a warm dark mode, turn on a gentle morning reminder during your cycle, or export an encrypted backup to move to a new phone. And the promise the rest of the app keeps is written right here: everything you log stays on this phone — no account system, no server, not a single line of analytics.
The same app, dimmed for late nights.
One toggle in Settings swaps the whole app to a soft charcoal theme — same calm layout, easier on the eyes.
Getting started takes about a minute: pick the day your latest period began so predictions can begin, and you’re in. It’s free for 7 days, then $9.99 once — no subscription, no account, ever.
Private by architecture.
A privacy policy is a promise; TeenCycle is the absence of anything to promise about. There’s no account, no email, no cloud, no server, no analytics, and no third-party trackers. Everything you log lives on your device, and only there. There’s nothing on our end to leak, sell, or hand over — because there’s nothing on our end at all. Delete the app and the data goes with it.
- No account. No email, no password, no sign-up.
- No cloud. No server stores your data, and no backup we could read.
- No analytics. No usage tracking, no event logging, no tracking pixels.
- No ads. Nothing in the app is selling you, or selling your attention.
TeenCycle is a tracker, not a medical device or contraception. If something about your cycle feels off, please talk to a clinician.
Follow along.
We keep a quiet presence in a few places — calm, parent-first notes and the occasional look behind the scenes. No feeds to get lost in.
