Frequently asked questions
How accurate are the valuations?
StampWorth gives an estimated market value based on the stamp's identity, condition, rarity and recent sales, cross-referenced with major catalogs. It's a guide to help you decide what to insure, sell, or keep — not a formal appraisal. Real prices vary with condition, cancellation, margins and demand.
Do I need to create an account?
No. StampWorth works without any sign-up. Your collection is stored on your device.
What does StampWorth Pro include?
Pro unlocks unlimited identifications, full market valuations, condition grading, catalog references and live eBay market offers. New subscriptions start with a 3-day free trial.
How do I manage or cancel my subscription?
Subscriptions are billed through your Apple ID. Open Settings → [your name] → Subscriptions on your iPhone or iPad, select StampWorth, and manage or cancel there. Cancelling stops the next renewal; you keep Pro until the current period ends.
How do I restore a purchase on a new device?
Open StampWorth, go to the paywall or Settings, and tap Restore. As long as you're signed in with the same Apple ID, your Pro access will be restored.
The scan didn't recognise my stamp — what can I do?
Try a clearer, well-lit photo with the stamp filling the frame and lying flat. If it still doesn't match, you can add the stamp manually with your own details (always free).
How do I delete my data?
Remove individual stamps inside the app, or uninstall StampWorth to delete your local collection and photos. See our Privacy Policy for details.
