מעקב מחזורCycle Tracker

Cycle Tracker is a private period log. Your data stays on your phone, and the app never connects to the internet.

• Log: period days and how heavy the flow is, on a clean calendar. Symptoms, mood and notes too, if you like.
• Estimate: the next period as a range of dates, from your own history only, not one sure-looking date. Until there are at least 3 full cycles it says "not enough data yet".
• Stats: average cycle and period length, and how much they vary. Past dates can be corrected and everything follows.
• Discreet reminders: the notification text is neutral and you choose it. The app name above the notification is neutral too.
• An optional PIN. It can't be recovered in any way, and the app says so up front. The PIN guards the screens; it does not encrypt the data.
• Summary for a doctor: a PDF of the dates you logged, for the period you choose. Notes are included only if you ask.
• Backup: a file you export yourself. It is not encrypted, and the app warns you before exporting.
• Delete everything: removes every date, note, reminder and setting and the PIN from the phone.

Privacy: no account, no server, no cloud sync, no usage statistics, no ads and no internet permission. That also means the app doesn't look for updates by itself; new versions appear on its page.

Important: this app is not contraception. Do not use it to avoid or to plan a pregnancy. Estimates come only from the dates you entered and they can be wrong. It gives no diagnosis and no medical advice, and it is not a medical device. For any medical question, ask a doctor.
