Cyclia is an Android app for tracking your period and cycle. Everything you enter stays on your own phone. There is no account, no advertising and no tracking.

Coming soon to Google Play

Zero analytics, no trackingThe app does not measure how you use it and does not follow you. It contains no analytics or advertising code.
Stored encryptedYour logs are kept in an encrypted database on your phone. An app lock with a PIN or fingerprint is available.
Track what you wantPeriod, symptoms and mood, fertility signs, intimacy, medication and notes. You switch on only what you want to see.
Predictions with an explanationThe app predicts your next period and fertile window, with a margin, and explains how the prediction was made.
Insights from your own cyclesAverages, charts, and which symptoms come back in which phase.
Also for irregular cyclesA separate setting for people with irregular cycles, for example with PCOS: a wider prediction, without false precision. More in the guide.
