Contact the developer
Include your iPhone or iPad model, iOS version, Slipbook version (shown in Settings) and the steps that led to the problem. Please do not send passwords, payment details or unredacted receipts. Your purchase records stay on your device, so I cannot look them up remotely.
For feature suggestions and public bug reports, you can also use the Slipbook feedback board. Posts there may be public; avoid personal information. Provider details are in the Impressum, and data handling is explained in the privacy policy.
Restore Premium
Premium is a one-time purchase, not a subscription. On a new or reinstalled device, sign in to the App Store with the Apple Account used for the purchase, open Slipbook Settings and tap Restore Purchases. An internet connection is needed to verify the purchase. Restoring Premium does not restore your locally stored products or receipts; those require a backup.
If the purchase is still awaiting approval, wait for approval before trying again. Apple handles billing and refund requests through Report a Problem.
Check reminders
Open Slipbook Settings and check notification permission and your reminder time. Also check Settings → Notifications → Slipbook on your device, along with Focus and notification summary settings. The product must have a confirmed future deadline and reminders enabled. iOS controls notification delivery; it cannot be guaranteed at an exact time.
Keep your data safe
Products and receipts are stored locally. Before deleting or reinstalling the app, save an encrypted backup in Settings → Data & Privacy → Backup & Restore. Keep the backup file and its password somewhere safe. Automatic iCloud backups must be enabled explicitly; they are not live synchronization.
A backup can only be opened with its password. I cannot recover a forgotten password or restore data that was deleted without a usable backup. If an import fails, keep the original file and contact support before deleting anything.
Review scanned receipts and dates
Use a clear, well-lit image of the whole receipt. You can also import a photo or PDF. Text recognition may misread or miss information, and support varies by receipt language and format. You can correct the proposed fields or enter your purchase manually. Always confirm return and warranty dates against the retailer’s terms and your documents. Slipbook does not submit claims or determine legal rights.
