Questions
Can I cancel anytime?
Yes. Cancel from your account page and you keep Pro access until the end of the billing period. No questions asked.
What happens to my watchlist if I downgrade?
Your cards stay saved. You just can't add new ones above the 5-card limit until you re-upgrade.
Is my portfolio data safe?
Portfolio data is linked to your account token and stays private. You can export it anytime as CSV (Pro) or simply delete it.
What does arbitrage detection actually show?
We compare TCGPlayer (USD) and Cardmarket (EUR) prices in real time and surface cards with significant price gaps — so you know where to buy cheap and sell high.
How does the grading calculator work?
Enter a card, your raw purchase price, and grading fees. We estimate PSA 10/9 values based on historical multipliers, then calculate your expected ROI factoring in grade distribution probabilities.
