🫙 Kefi — Privacy Policy
Effective August 12, 2026
What we collect
Nothing. Kefi has no user accounts, no server, no analytics, no advertising, and no third-party SDKs. We never see your name, your email, your location, or anything about how you use the app.
Where your data lives
Everything you create in Kefi — your kefir's name, straining history, recipes in progress, accessories, family tree — is stored locally on your device using Apple's SwiftData. It is never uploaded anywhere. If you delete the app, that data is deleted with it.
Notifications
Straining reminders are local notifications, scheduled entirely on your device. No push servers are involved.
Widgets
The home-screen widget reads a small snapshot of your kefir's state from a shared container on your device (an App Group). It never leaves your phone.
Adoption certificates and QR codes
When you gift a descendant, Kefi generates a QR code on your device. The code contains only what you can see on the certificate: the kefir's name, generation, and family line. Sharing it is entirely up to you — there is no server behind it.
Purchases
Subscriptions are processed by Apple through the App Store. We never receive your payment information. You can manage or cancel your subscription anytime in your device Settings.
Children
Kefi collects no data from anyone, children included.
Changes
If this policy ever changes, we will update this page and the effective date above. Given that Kefi's design goal is to collect nothing, don't expect much movement here.
