Private Period Tracker is built on one premise: a cycle history is the most sensitive data on a phone, so it stays on the phone. There is no account to create, no sync to switch off, and no server holding a copy of any of it.
It covers period and cycle tracking, fertility, pregnancy and perimenopause, and it works with the network off because it never needed the network. Everything you record is encrypted locally on the handset.
There is no server to subpoena and no third party to leak it, because the data never leaves the device in the first place. No ads, no trackers and no data selling anywhere in the app.

Common questions
Does Private Period Tracker need an account?
No. There is no sign-up and no login. The app works fully offline from the moment it is installed.
Where is my cycle data stored?
On your own phone, encrypted locally. Nothing is uploaded, so there is no server copy and nothing for anyone to breach.
Does it track fertility and pregnancy as well?
Yes. Period and cycle tracking, fertility, pregnancy and perimenopause are all in the same app.
Are there ads, or is the data sold?
Neither. There are no ads, no trackers and no data selling in it.
