Family Purity (Taharat HaMishpacha) Cycle Tracker

Noga helps you track your cycle and family-purity calculations privately, with all your data kept on your device. If you need help, have a question, or want to report something, we're glad to hear from you.

Frequently asked questions

Is my data private?

Yes. Everything you log stays on your iPhone. Noga has no account and no server — we cannot see your data. See our Privacy Policy for full details.

How do I edit or delete an entry?

Open the Log tab, tap the entry you want to change, and edit or delete it there. Predictions and the calendar update automatically.

How are the predictions calculated?

Noga calculates the three classic vestot — Onah Beinonit, Yom HaChodesh, and Haflagah — from the dates you log. The in-app guide ("How to use Noga" in Settings) explains each one, and the app supports Veset Kavua and Onat Or Zarua for those who keep them.

Is Noga a halachic authority?

No. Noga is a personal tracking and reminder tool. It is not a substitute for the guidance of a qualified rabbinic authority. For any halachic question, please consult your rav.

How do I change the language?

Noga follows your iPhone's language. To switch, go to iOS Settings → Noga → Language and choose English or Hebrew.
