Privacy Policy
Last updated: July 2026
Muddah is designed to be private by default. It works entirely on your device.
Data we collect
None. Muddah does not collect, transmit, or sell any personal data. There is no account and no sign-in. The app contains no third-party analytics, advertising, or tracking SDKs.
Where your data lives
The documents, family members, expiry dates, notes, and any photos or scans you attach are stored only in Muddah's local storage on your device, protected by iOS Data Protection. This information is never uploaded to us or to any cloud service. iCloud and server sync are off; Muddah has no server.
Notifications
Expiry reminders are scheduled and delivered entirely on your device using local notifications. No reminder content leaves your device. You can turn notifications on or off at any time in iOS Settings, choose what time of day they arrive, and hide names from lock-screen notifications inside Muddah.
Notes you write on a document are never included in a notification.
Camera
If you scan a document, Muddah uses the camera only to capture that document. The scan is turned into a PDF and stored in Muddah's local storage on your device. Reading the expiry date out of a scan also happens entirely on your device, using Apple's on-device text recognition. No image and no recognised text is ever uploaded.
Face ID
If you enable the app lock, Muddah uses Face ID or your device passcode only to unlock the app on this device. Biometric data is handled entirely by iOS and is never accessible to, or stored by, Muddah.
Export and import
Exporting writes a JSON file containing your documents and family members, which you then choose where to send. Photos and scans are not included in that file. Once you share the file, it is outside Muddah's control, so treat it like any other copy of your documents.
Your control
You can delete everything from inside the app at any time (Settings › Delete all data). Because all data is local, deleting the app also removes all of your data from the device. There is nothing stored elsewhere for us to delete.
Not affiliated with any government
Muddah is a personal record-keeping and reminder tool. It is not affiliated with, endorsed by, or connected to any government or government service, and it does not provide legal or immigration advice.
