Privacy Policy

What We Collect
ProofOF stores the data you enter on your device first: item names, retailers, purchase dates, prices, serial numbers, receipt photos, notes, and the deadlines we track for you. If you sign in and enable sync, copies are stored on the sync server so they can be restored or shared across your own devices.
How It's Used
Your data is used only to provide the service: showing countdowns, sending the reminders you requested, and displaying your digital receipt barcode. We do not sell your data, and we do not use it for advertising or analytics.
Local First
Until you sign in and turn on sync, everything stays in the local database on this device. Deleting the app or the item removes it locally. Signed-in users can delete their account and server-side copies at any time.
Permissions
Camera access is used to photograph receipts and scan barcodes. Notifications are used only for deadline reminders you opt into. You can revoke either in your device settings at any time.
