Most cycle trackers store your most personal data on their servers, tied to an account. Quiet Cycles keeps it on your phone — and only your phone.

No account, no sign-up, no email. You open the app, answer three things, and you're tracking.
One app, two views. Flip on TTC mode and the whole app re-centers on fertility — same data, different focus.
The home screen counts down to your fertile window and ovulation day, instead of your next period — with a daily status like "high fertility day."
Log ovulation test results and optional morning temperature. Temperature confirms ovulation after it happens — it never pretends to predict it in advance.
A gentle reminder on the day your period is due — the sensible day to test, not before, when false negatives are most common.
Share your fertile-window status with a partner through an encrypted share code. They see the window — never your symptom logs or notes.
No account. No cloud database. No analytics, no ad trackers, no crash reporters. Your data lives on your device, your encrypted backup is a file you control, and a delete-all button wipes everything on demand.
The big apps charge about $10 a month and still keep your data on their servers. Quiet Cycles Premium is $10 a month — and your data never leaves your phone.
