Nine
Privacy Policy
Last updated 28 August 2026
Nine works out due dates and fertility windows from dates you type in — it has no reason to talk to a server, and it doesn't. (AppsRicot's general privacy policy covers anything not specific to Nine.)
Data we collect
Nine collects nothing about you. There is no account, no sign-in, no cycle log, and no analytics.
- The dates you enter — last period, conception, transfer, or ultrasound date, and your saved results — stored only on your device, and included in your own iPhone backup if you have one. They are never sent to us, and we have no way to read them.
- Your settings — cycle length and preferences, also on-device only.
Third parties
One service is involved, and only if you buy the one-time unlock:
- RevenueCat manages the purchase. When you buy or restore Pro, it receives the App Store receipt and an anonymous identifier it generates for your install. It does not receive the dates you entered, your name, or your email address. See the RevenueCat privacy policy.
There is no analytics SDK, no advertising SDK, and no crash reporting SDK in Nine, and the app makes no network calls of its own. If you have Apple's diagnostics sharing switched on, Apple may send us anonymous crash traces; you can turn that off in Settings → Privacy & Security → Analytics & Improvements.
Permissions
None. Nine does not ask for the camera, microphone, location, contacts, photos, or notifications, because it does not need any of them.
Medical disclaimer
Nine performs standard obstetric date calculations. It does not diagnose pregnancy, does not provide medical advice, and every figure it shows is an estimate. Consult a healthcare provider for medical care.
Payments
The one-time unlock is billed by Apple. We never see your card details — only whether the purchase was made.
Children
Nine collects no data from anyone, including children.
Deleting your data
Everything is on your device, so deleting the app deletes all of it. The app also includes a clear-all-data control if you need to remove your dates without deleting the app. To cancel or restore the one-time unlock, use Settings → your name → Subscriptions on your iPhone, or Restore Purchases in the app.
Changes
If this policy changes, the date at the top changes with it. Material changes will be noted in the app's release notes.
