Cardiyo Support
Scan a card. Know its worth. Here is how it actually works.
1. How does scanning work?
Point the camera at a card and hold it steady. The photo goes to Cardiyo's scanner, which matches it against an index of card images and tells you exactly which print it is.
Auto-capture fires by itself once a card is steady in the frame — Quick or Relaxed, your choice. You can pinch to zoom, or upload a picture from your photo library instead of using the camera. Rapid scanning lets you keep shooting a stack while cards are identified in the background; the results land in the refine queue and finish with a summary. Sealed products scan too, not just single cards.
2. Cardiyo didn't recognise my card. What now?
If Cardiyo is unsure, it shows you the next-best matches and asks you to compare your card's bottom edge — the set symbol and the number. That usually settles it.
If there was no match at all:
- Photograph the card again, flat and filling the frame, with no glare on holos.
- Search the catalogue by name, number or set.
- Use the guided picker: language → era → set → card.
Cardiyo would rather show you nothing than file the wrong print in your collection.
3. Why is there no price on this card?
Because Cardiyo doesn't have one for that print. 70,494 of the 98,918 prints in the catalogue carry a price; counted by card, 33,688 of 41,679 have a price on at least one print (figures as at 12 August 2026, updated with each release). Where none of the sources Cardiyo mirrors lists that print, the tile stays empty.
An empty price tile means empty data. It doesn't mean a broken app.
4. Why is the German price different from the English one?
Because they are different cards in different markets.
Cardiyo shows up to four price tiles per card — US · TCGplayer, EU · Cardmarket, US · eBay, DE · eBay — and fills whichever ones have data for that print. A German print's home market is Cardmarket, priced in euros, with German eBay alongside it. An English print's home market is TCGplayer and eBay in the US. Different supply, different demand, different price.
Cardiyo prices every print against its own market. It never converts an American price and calls it a German one. You can set the app's display currency to USD, EUR, GBP or CAD; that changes how a price is written, not which market it came from — the tile always tells you which.
5. What does "no price is better than a wrong price" mean in practice?
The tile stays empty. Cardiyo will not:
- borrow a price from another language,
- interpolate a price from similar cards,
- invent a number when a source has none.
Prices are mirrored every night. What you see is the most recent completed refresh.
Three more things worth knowing. eBay live listings are asking prices — what someone wants, not what anyone paid; recorded sold listings are shown separately, and Cardiyo never mixes the two. A price in Cardiyo is a market estimate: it is not a valuation, and it is not advice about buying or selling. And the estimates come from named sources — single-card prices from TCGplayer, Cardmarket and eBay; graded prices and population reports from PokemonPriceTracker.
6. How does the free scan limit work?
Free gives you 10 scans a day. The counter resets at midnight in your device's local time zone. Pro is unlimited.
7. What do I get for free?
Free is a real collecting app, not a trial:
- 10 scans a day
- 2 collections, 50 cards each — copies count, so 100 cards in total
- All four card languages, all price sources
- Graded prices, population reports, real eBay sales
- Daily price refreshes
- 6 months of price history
- Pokémon Center drop alerts, checked every 30 minutes
- The Cardiyo Light and Cardiyo Dark themes
Everything you need to answer the question "is this card worth anything?" is free.
Pro adds unlimited scans, unlimited collections and cards, the full price history Cardiyo holds — currently a year of daily prices, and growing — drop alerts every 5 minutes, all 7 themes and all 6 fonts, CSV/Excel export, and early access to new features. In the U.S. App Store USD 5.99 per month or USD 59.99 per year; in Germany 6,99 € per month or 69,99 € per year, VAT included. Both renew automatically until you cancel. Apple sets the price in your country's App Store, and the binding price is the one shown on the paywall before you buy.
8. How do I cancel Pro, and can I get a refund?
Cardiyo cannot cancel your subscription and cannot refund you. Apple is the seller.
Cancel: iOS Settings → your name → Subscriptions → Cardiyo → Cancel. Do it at least 24 hours before the end of the current period, or the next one bills.
14-day withdrawal: as a consumer in the EU or EEA you can withdraw from the purchase within 14 days of receiving Apple's receipt, without giving a reason. Because Apple is the seller, that right runs against Apple, not Cardiyo, and you exercise it with Apple — through your purchase history in your Apple Account, or at reportaproblem.apple.com. The details are in Apple's Media Services Terms and Conditions.
Refund outside those 14 days: reportaproblem.apple.com. Apple decides, not Cardiyo.
Cancelling stops the renewal. Pro keeps working until the period you already paid for runs out.
9. How do I export my collection?
With Pro you export your collection as a CSV or Excel file (XLSX). Export is not part of Free.
10. How do I delete my account, and what is deleted with it?
You delete it yourself, in the app, under account settings — that is the fastest route and it needs nobody's approval. If you cannot get into the app, email [email protected] and ask for deletion; that request is carried out too, within one month at the latest.
Deletion removes your sign-in, profile, collections, scan history, push tokens and subscription status from the live service. Three things remain at first, exactly as the privacy policy states: a recovery snapshot of your account, your profile picture file, and the subscription log rows from the app stores. If you want those gone too, email [email protected] from your registered address and ask for complete erasure — we delete them by hand and confirm when it is done.
Two things Cardiyo cannot delete for you: Apple's record of your purchase, and the subscription history RevenueCat keeps from Apple's receipts. Those sit with Apple and RevenueCat and follow their retention, not Cardiyo's.
11. What do the Pokémon Center drop alerts do?
Cardiyo watches the Pokémon Center storefront and looks for the virtual queue that builds up in front of a drop. When it appears, you get a push notification. Free checks every 30 minutes, Pro every 5.
Alerts only reach you if you allow notifications when the app asks. You can take that back at any time, in Settings or in your device's notification settings, and Cardiyo stops sending.
That is all the feature does. It does not queue for you, buy for you, or get you a better place in the queue. Cardiyo has no relationship with Pokémon Center.
12. Which languages does Cardiyo support?
Two separate answers.
The app: English and German.
The cards: English, German, French and Japanese. The scanner detects automatically which language a card is printed in, so a German card is filed as a German card — German artwork, German market price.
13. What are graded prices and population reports?
A graded card has been assessed by a grading company and sealed, with its grade, in a hard plastic case (a slab). Cardiyo prices those separately, by grade and by grading company — a PSA 10 and a CGC 9 are not the same object and do not carry the same price. Graders covered include PSA, BGS, CGC, SGC, ACE and TAG.
A population report counts how many copies exist at each grade. Cardiyo shows the population and how it has moved over time. It is the fastest way to see whether a "rare" grade is actually rare.
14. Why does this card have no graded data?
Graded prices exist for 16,613 of 41,679 cards (figure as at 12 August 2026, updated with each release). Graded data only exists for cards people actually send in for grading, and a graded price also needs slabbed copies to have sold. Most cards never see either.
Same rule as everywhere else in the app: no data, blank tile.
15. Is my scan photo stored?
No. The photo goes to Cardiyo's scanner, is held only for as long as the match takes, and is then discarded. It is not written to storage and it is never attached to your account.
What is kept is the scan record: which card was recognised, the name, number and set read off it, the card's language, how many matches came into question, and the card's value at that moment. Text, not pictures. How long a scan record is kept is set out in the privacy policy.
The scanner runs on Cardiyo's own server. Where that server is, who operates it, and what protects your data when it reaches the provider in India is set out in the privacy policy too.
16. Does Cardiyo sell my data?
No. Cardiyo does not sell your data, and no third-party analytics, advertising or tracking SDK ships in the app. No Firebase Analytics, no Sentry, no AppsFlyer, no Facebook SDK, no Adjust, no PostHog — none of them is in the app. The one third-party component that does ship is RevenueCat, which manages your subscription status. It is not an analytics or advertising SDK, and Cardiyo does not use it as one.
That is not the same as saying nobody else touches your data. A handful of companies process data on Cardiyo's instructions, because the app cannot run without them: Supabase hosts the database that holds your account and your collection; Apple sells Pro and passes the receipt to RevenueCat, which keeps your subscription status; drop alerts reach your device through Expo's push service and then Apple's or Google's notification service. They work for Cardiyo, not for themselves. The privacy policy names each one, says what it receives, and says where it is.
Cardiyo earns money two ways today, and you should know both. Pro subscriptions, and eBay affiliate commission: the eBay links in the app are affiliate links (eBay Partner Network). If you buy something through one, eBay may pay a commission. Your contract for that purchase is with the eBay seller, not with Cardiyo.
Tapping an eBay link takes you to eBay. The link carries a campaign id so eBay can attribute the visit — that is how the commission is counted. From that point eBay's own terms apply, including eBay's own tracking.
17. A card or a price is wrong. How do I report it?
Email [email protected]. The contact block below lists what to include. A report with the collector number and a screenshot can be checked and fixed. "The price is wrong" on its own is not enough to act on.
18. Does Cardiyo work offline?
Scanning does not. Recognition runs on Cardiyo's server, so every scan needs a connection. Prices come from the server too, so they need a connection as well.
Without a connection the app cannot load fresh data — treat Cardiyo as an online app.
19. Is there an Android version?
Cardiyo launches on iOS first. An Android version is built on the same account system, so when it ships you sign in and your collection is there. Until then, iOS only.
20. Is Cardiyo official?
No. Cardiyo is an independent app. It is not produced, endorsed or sponsored by, and is not affiliated with, Nintendo, Creatures Inc., GAME FREAK inc., The Pokémon Company International, Wizards of the Coast or Pokémon Center. Pokémon and all related names are trademarks of their respective owners.
Cardiyo does not sell cards, does not trade cards, and has nothing to do with the companies that make them.

To make a report actionable, include:
- Wrong price: the card name, collector number and set; the language (EN / DE / FR / JA); which price tile (US · TCGplayer, EU · Cardmarket, US · eBay, DE · eBay); what it shows and what you expected; a screenshot.
- Wrong card after a scan: a photo of the real card, and what the app suggested instead.
- Anything else: the email address on your account, your device and OS version, and the app version.
Cardiyo is run by one person. There is no support team, and no response time is promised for questions or bug reports — reproducible bugs go to the front of the queue. Privacy is different: requests under the GDPR (access, correction, deletion, objection, data export) are answered within one month, as the law requires.
For billing, cancellation and refunds, Apple is the seller — see question 8. Those cannot be settled from this address.
