Period & cycle tracker

CycleKept

Track your period, symptoms and predictions with the discretion this data deserves. Nothing about your cycle ever leaves your device.

Not out yet. CycleKept is built and in testing, and arrives on Google Play first. Join the waitlist and we'll email you the day it lands — one email, nothing else.

What CycleKept does

Log fast — flow, symptoms, mood and notes in a tap.
Predictive — cycle day, a next-period estimate and a calendar view, worked out from your own history.
Nothing to subpoena — there is no account and no copy of your cycle anywhere but your phone.
Reminders scheduled on your device; nothing is sent through a server.
A cycle PDF for a check-up, generated on your phone and shared only when you send it.
An optional biometric app lock.

CycleKept shows estimates from what you log. It is not a medical device, not a diagnosis, and not a contraceptive.

The same promise as every Coffer app

What you record lives in an encrypted database on your own device. There is no account to create, no analytics watching you, and no server of ours holding a copy — so there is nothing for us to leak, sell or lose. Export your data whenever you like; nothing you have already written down disappears if you stop paying.
