Privacy Policy
The short version
Zen Otto does not collect your data. There is no account, no sign in, no analytics and no advertising. Nothing you log is sent to us, because there is nowhere for it to be sent to. We cannot read your baby's feeds, diapers, weights, photos or vaccination records, and neither can anyone else.
Where your data lives
Everything you enter is stored on your iPhone.
If you turn on iCloud sync, which is off unless you switch it on, your data is copied to your own private iCloud database so it appears on your other devices. That copy belongs to your Apple Account. It is governed by Apple's privacy policy, not ours, and we have no access to it at any point.
Photos you add are stored in the app on your device. The app uses Apple's photo picker, which means it never gets access to your photo library, only to the individual pictures you choose.
What we collect
Nothing.
No personal information, no health information, no usage data, no crash reports, no device identifiers and no location. The app makes no network requests of its own.
Payments
Subscriptions and the one time purchase are handled entirely by Apple. We never see your card, your billing address or your Apple Account. All we ever learn is whether this copy of the app is unlocked, and that answer comes from your device rather than from a server of ours.
Notifications
If you turn on feed reminders, the notifications are scheduled on your device by iOS. Nothing about them leaves your phone.
Children
Zen Otto is a tool for parents and carers, and it is used by adults. It records information about a child, and that information stays on the adult's device. Because nothing is collected or transmitted, no personal information about a child is ever received by us.
Deleting your data
Deleting the app removes everything stored on your device. If you turned iCloud sync on, you can remove the synced copy in iOS Settings under your Apple Account, then iCloud, then Manage Account Storage.
This app is not medical advice
Zen Otto shows you your own log, and it shows published reference ranges with the body that published them named on screen. It never compares the two, and it never draws a conclusion about your baby. It is not a medical device, it does not diagnose anything, and it is not a substitute for your doctor or health visitor.
Changes
If this policy changes, the updated version will be posted here and the date at the top will change.
