Other period trackers sell your cycle to advertisers, lock features behind paywalls, and drown you in symptoms you never asked to track.
Three things. That's it.
Privacy
On your phone. That's it. No servers, no cloud, no company has your data.
Simplicity
Track your period. The end. No symptom overload, no fertility mode, no noise.
Free
Actually free. No premium tier, no paywalled features, no subscription.
Them vs. us
Not naming names. You already know.
This is the whole app
No, really. That's it.




Built by someone who actually uses it.
“Every period tracker I tried either sold my data, charged me for basics, or buried me in features I didn't ask for. So I built one that does exactly what it should — tracks your period, predicts the next one, and keeps your data on your phone.”
Your cycle is nobody's business but yours.
No investors
Self-built, self-funded. Nobody upstream gets a say.
No ads, no data sales
Your cycle stays on your phone. There is nothing for us to sell.
Free forever
Every feature, every user. Optional support unlocks nothing, because nothing is locked.
