Your cycle data never leaves your phone.

Period tracking built on the assumption that this is nobody else's business. No account, no sync server, no analytics, no ad network. Private by architecture rather than by promise.

Coming to the App Store Privacy policy

Why this matters

Most cycle trackers are advertising businesses wearing a health app's clothes. The data they hold is among the most sensitive a person can generate, and it sits on someone else's server under someone else's terms of service.

Ripple has no server. There is no account to create and nothing for us to request, sell or hand over — we never receive your data at all. If you want a backup, it’s encrypted on your phone with a passphrase only you know before it goes anywhere. When your device is the only place the data can be read, who else can see it stops being a policy question.

Private by design, not by promise.

01 Encrypted when locked iOS encrypts Ripple’s data whenever your phone is locked. Without your passcode, it can’t be read.
02 App lock Require Face ID, Touch ID or your passcode every time Ripple opens.
03 Hidden in the app switcher Ripple blanks its own preview, so nobody sees your calendar while you swap apps.
04 Your backup, your key Optional backups to iCloud Drive or a file are encrypted on the device with a passphrase we never see.
05 Apple Health, if you want it Writes flow levels to Health. Reads nothing else — no heart rate, no activity, no weight.
06 Apple Watch Phase, cycle day and the countdown to your next period, on your wrist, over an on-device channel.
$6.99

once.

You pay for the app instead of being the product. That is the entire reason there is no ad network and no data to sell — the business model doesn't need one.

Ripple tracks your cycle, not your data.

Zero network connections, zero third-party SDKs, zero analytics. Everything you log is encrypted on your phone, and the only copy that ever leaves it is a backup you encrypted yourself.
