Frequently asked questions
Can't find your answer? Email info@coinalbum.eu.
Do I have to pay to track my collection?
No. Collection tracking, statistics, and complete-set tracking are free forever. You only pay for AI photo recognition (credits) and, optionally, Marketplace access.
What's a credit and when is it used?
One credit = one AI coin recognition, whether from a photo taken in the app or uploaded from your phone. A credit is only used after the app successfully processes the photo and returns a result. Manual entry without AI is always free and never uses a credit.
What if the app identifies a coin incorrectly?
The AI recognition result is always fully editable — you can correct anything before saving without using another credit. If the app can't process the photo at all (an error), no credit is used.
What does the "Verified" badge on a user mean?
It means an app administrator manually checked that user. It isn't independent identity verification like a bank ID — so we recommend caution for larger amounts even with verified users.
Do you store photos of my coins?
No. A photo is sent for AI processing and discarded immediately after the result comes back — the app never stores it permanently.
Can I install the app on my phone?
Yes — the app is a PWA (Progressive Web App). In your phone's browser, choose "Add to Home Screen" and it then behaves like a standalone installed app.
Do I have to unlock the app with my password every time?
No — if your phone or computer supports fingerprint, Face ID, or Windows Hello, you can set it up in Settings as a faster alternative to your password. Your password stays as a backup.
How do I delete my account?
In the app under Settings → Personal details you'll find the option to permanently delete your account.
Do you support every eurozone country?
Yes, the app covers every country using the euro, including specifics like Germany's five different mints.
How does payment work on the Marketplace, is it safe?
The app isn't a party to the trade between collectors — it only connects you. Agreeing on a price, payment (QR payment to the seller's account, or cash on delivery) and shipping all happen directly between you. We recommend cash on delivery for larger amounts. More in How it works.
How does the app handle my personal data?
See details in the Privacy Policy. In short: passwords are never stored in readable form, payment details are only seen by Stripe, and coin photos are never stored permanently.
