FAQ

Questions & Answers

Is MarketDex free?
Yes. Scanning, lookup, live prices, the full collection tracker, trade compare, trending and events are free. Vendor Mode — the professional toolkit for sellers — is a paid tier. AI Grading and the authenticity checks come with free credits and a Pro quota.
Where do the prices come from?
Three sources side by side: eBay sold listings (last sold and the average of the last five), the Cardmarket price guide (1-day average, trend, from), and TCGplayer market prices per condition. Graded cards use real sold comps per grading company and grade. MarketDex keeps its own price history for every card and refreshes it nightly, so the charts keep working even when a source is slow.
What cards are supported?
Every Pokémon TCG set in English and Japanese — 450+ sets and 48,000+ cards, including Pocket, promos, McDonald's and Trainer Gallery sets — plus German, French, Italian, Spanish and Portuguese prints through our secondary catalogue. Other games are on the roadmap.
How accurate is AI grading?
AI estimates are a pre-screening tool — they assess centering, edges, surface and corners from your photos. Actual grades from professional services may differ by 1–2 grades. We always show a confidence indicator so you know how sure the AI is.
Can I see Cardmarket sellers from my own country?
Yes. On every card the Cardmarket tile has a country dropdown — Netherlands and Belgium at the top, every other Cardmarket country below. "View Sellers" opens the exact product on Cardmarket, in English, filtered to sellers from that country. Your pick is remembered for every card.
What is Vendor Mode?
Vendor Mode unlocks the pro toolkit: set-based bulk pricing, multi-card buy and sell sessions with per-card offers, inventory import, buy & sale ledgers with grading detail, and dated CSV exports built for trade-show days.
What data do you collect?
Almost none. Your collection, transactions and vendor books live on your phone, and only your own backup is stored in the cloud when you sign in with Google or Apple. We don't run ad tracking and we don't sell data. Full details in our privacy policy.
How often does the app update?
Most improvements ship over the air within days — no store update needed. The bell on Home lists every release note. Join the Discord for previews, bug reports and direct contact with the team.
