DotDiary
Private period tracker — your data stays in Apple Health
DotDiary is a private period and cycle tracker that stores everything in Apple Health on your iPhone — no account, no ads, no tracking, no subscription. There's no server holding your cycle data, so nothing to breach, sell, or subpoena. It's still a full tracker: single-tap logging, predictions with confidence ranges, symptom, mood and fertility tracking, trends, and a doctor-ready PDF. Free import from Flo or Clue. Free to use, with a one-time $2.99 Pro unlock, no subscription.
Hi everyone — I'm the maker of DotDiary.
I built it because period-tracking data is some of the most sensitive data a person can generate, yet almost every tracker stores it in the cloud behind an account, where it can be breached, sold, or subpoenaed. DotDiary takes the opposite approach: it writes your data straight to Apple Health on your iPhone. No account, no DotDiary server, no network calls. If I disappeared tomorrow, your data would stay exactly where it already is — on your phone.
It's still a full tracker: single-tap logging, cycle predictions with confidence ranges, symptom, mood and fertility tracking, trends, and a doctor-ready PDF export. You can import your Flo or Clue history for free. It's free to use, with a one-time $2.99 Pro unlock and no subscription.
I'd love your feedback — especially on the privacy model, and anything that would make it more useful. Happy to answer questions here.
