Question 1

What is Grail?

Accepted Answer

Grail is an iOS app for tracking a portfolio of trading cards — Pokémon TCG and One Piece Card Game. It shows the real-time value of your collection, keeps a daily price history, and lets you organize cards into one or more wallets.

Question 2

Is Grail free?

Accepted Answer

Yes. Grail is free to download and use, and it's supported by non-intrusive banner ads. Optional paid features will come in the future: portfolio tracking, wallets, and price history stay free.

Question 3

Which card games does Grail support?

Accepted Answer

Pokémon TCG and One Piece Card Game today, covering both English and Japanese card printings where price data is available.

Question 4

Where can I download Grail?

Accepted Answer

Grail is available for free on the App Store for iPhone and iPad. There's no Android version yet: join our Discord to hear when it arrives.

Question 5

How do shared wallets work?

Accepted Answer

You can invite other collectors to a wallet by sharing an invite code. Everyone in a shared wallet sees the same cards and quantities in real time, and can have an editor or viewer role — useful for tracking a collection you manage together, like a family or a duo of collectors.

Question 6

Can I track graded cards (PSA, BGS, CGC)?

Accepted Answer

Yes — you can mark a card as graded, record the grading company, grade, and a link to the certificate, and set its market value manually (graded cards don't have automated market pricing yet). Automatic grade-based price estimation is planned for a future update.

Question 7

Where do card prices come from?

Accepted Answer

Grail pulls current prices from TCGPlayer (US market, USD) and Cardmarket (EU market, EUR) — two of the largest trading card marketplaces — and computes daily historical snapshots through its own backend. Prices are shown for informational purposes — see our Terms of Service for details.

Question 8

What happens to my data?

Accepted Answer

We collect only what's needed: your account email, the wallets and cards you add, and usage events (never card values or amounts) to understand which features are used. Ads are served by Google AdMob, based on your consent choice. Card scanning runs entirely on your device — photos are never uploaded. Full details are in our Privacy Policy.

Question 9

Does Grail sell my data or show ads?

Accepted Answer

Grail is free and shows non-intrusive banner ads to support that — never interstitial or rewarded ads. We don't sell your data or share it with data brokers. See our Privacy Policy for the full breakdown.

Question 10

Does Grail work on Android?

Accepted Answer

Right now Grail is iOS-only, but an Android version is planned for the future.

Question 11

Can I see how my collection's value has changed over time?

Accepted Answer

Yes — Grail saves a daily snapshot of every wallet's value, with a chart you can filter by period (7, 30, 60, or 120 days). It's a real history, not an estimate reconstructed from today's price.

Question 12

Can I keep a list of cards I want to buy?

Accepted Answer

Yes, in two distinct ways: a personal wishlist for cards you want, and a shared wantlist for group wallets, so every member can see what the shared collection is missing.

Question 13

Can I group cards from the same set?

Accepted Answer

Yes — in any wallet you can turn on "Group by set": the cards of each set are gathered into a stack showing how many cards you have and their total value. Tap a stack to see every card in that set.

Question 14

How do I know which cards in my portfolio are going up or down in price?

Accepted Answer

The Markets section shows the biggest gainers and losers calculated from the cards you actually own, not a generic market leaderboard.

Question 15

Can I share one of my cards on social media?

Accepted Answer

Yes — you can generate a ready-to-share image with grading, ROI, a 30-day sparkline, and a QR code, in portrait or landscape format.

Question 16

What languages is Grail available in?

Accepted Answer

Italian, English, German, Spanish, French, Japanese, and Simplified Chinese.

Question 17

Do I need to create an account to use Grail?

Accepted Answer

No: you can explore Grail as a guest — search cards, see prices and charts, browse the Pokédex. To save your collection and use the wishlist and shared wallets you need a free account, which you can create with Apple, Google, or email. You can also lock the app with Face ID/Touch ID.

Question 18

Can I buy cards directly from Grail?

Accepted Answer

Grail doesn't sell cards — but from any card page you can open a direct search on TCGPlayer or Cardmarket to buy it from the marketplace you prefer.
