Contact us

Email support@cardero.me. We reply within 1–2 business days. Please include your iPhone model, the app version (at the bottom of Settings), roughly when the problem happened, and what you saw.

We never ask for passwords, full card numbers or card security codes.

How do I scan a card?

On Home, tap "Scan a card". Point the camera at one card and tap the round shutter button ("Take photo"). To use a picture you already have, tap the photo library button ("Choose from photos"). Tips are in Settings → "How to scan".

What counts toward my free scans?

Cardero is free to use today, with a daily allowance of free scans. Home shows how many are left today. The allowance resets at midnight UTC.

• If we can't find a card in your photo, it doesn't use a free scan.

• If scanning fails on our side and you get no result, it is not counted.

• A scan that identifies a card is counted. So is a card read from your photo that is not in our catalog.

• Choosing another version, tapping "None of these" or adding a card to a collection neither uses a scan nor gives one back.

• "Check again" is free, once per scan.

• History ("See all" on Home) shows "Counted" or "Not counted" for each scan.

The app shows the wrong card

• When Cardero is not sure, it asks "Is this your card?". Check the year and number printed on your card. Choose the "Top match" or a version under "OR ONE OF THESE", then confirm. If none fits, tap "None of these".

• For a card in a collection, tap "Change" on the card (shown when other versions exist), choose the version printed on your card, then "Use this version".

• On a past scan opened from History, a result that needs your check or has no value may offer "Check again". It runs the identification again on the same photo.

Where do values come from?

• Values are estimates in US dollars from an AI model (currently Google Gemini), based on the card's identity and the condition read from your photo. The card shows when its estimate was made.

• An estimate is not a sale price, an offer or an appraisal. Cardero does not grade your card, and on a graded slab it doesn't check the grade on the label.

• "Listings" opens searches on third-party shopping sites, such as eBay and TCGplayer. They are searches, not records of sales, and we don't control those sites.

No value? "No value yet" means there is no estimate, for example when our catalog and the reading of your photo disagree. A card saved without an estimate may get one later. Saved estimates are not updated automatically.

Collections

• To add a card, slide the bar at the bottom of its result ("Slide to add"). The first time, you name your collection ("Create your first collection") and tap "Create and add".

• "Add to…" on a card lets you choose the collection, or make a "New collection".

• You can have up to 50 collections, with names of up to 40 characters. "Rename" on the Collection screen renames one.

• Each scanned card is in one collection at a time. To move it, open it, tap "Remove" and confirm, then tap "Add to…".

Reinstalling or a new phone

You use Cardero without signing in. Your scans and collections are stored with an anonymous account on our servers. Deleting the app can lose access to them.

• After a reinstall on the same iPhone, Cardero may find your account again. If it does, your scans, collections and their photos come back, and you may see "Welcome back. Your collection is here."

• A new phone starts with a new anonymous account. Earlier scans and collections do not move to it.

• We cannot recover a lost account: it has no name, email or password to match to you.

Deleting your account

Go to Settings → "Delete account" and confirm. Your account is closed at once, and this app starts fresh with a new account. Photos and scan records are kept without any link to you, and your IP address (stored only in hashed form) is unlinked from them. Backups made before you delete keep the old link until they expire (up to 12 months). The new account may not include free scans. Deleting your account does not cancel a subscription.

How do I cancel or get a refund?

Deleting the app does not cancel a subscription. Cancel where you bought it:

• App Store: iPhone Settings > [your name] > Subscriptions. Apple handles refunds at reportaproblem.apple.com.

• Our website: email support@cardero.me and we will cancel it for you.

Privacy

Scan photos are sent to our servers and our AI recognition partners (currently Google Gemini and Ximilar) to identify your cards and estimate their value. They aren't shared with other collectors. Full policy: https://cardero.me/privacy
