Privacy policy
Last updated: 10/23/2026. Contact: 6polen9@gmail.comWhat stays on your device. Your filters, saved decks, simulator settings and Pro key are stored in your browser's local storage on your device. We don't receive them.
Payments. Pro is sold through Stripe. Stripe collects your payment details and email under Stripe's privacy policy. We receive your email and a customer ID from Stripe to confirm your subscription; your Pro key contains that customer ID and email. We never see your card number.
Buy links. Card buy buttons open TCGplayer, eBay, Cardmarket or other shops. Some are affiliate links, so the shop can tell a purchase came from us and may pay us a commission. Those shops handle your visit under their own privacy policies.
Ads. Free users see a banner ad served by Google AdSense. Google and its partners use cookies or similar technology to show and measure ads, which may be personalised based on your visits to this and other sites. You can turn off personalised ads at Google Ad Settings; see how Google uses data from partner sites. In the EEA, UK and Switzerland you'll be asked for consent first. Pro users see no ads.
No selling of data. We don't sell personal data. Our host may keep standard server logs (IP address, time, page) for security and operations.
Children. The app isn't directed at children under 13, and Pro purchases require an adult's payment method.
Deleting your data. Clear the site's data in your browser or uninstall the app. To delete payment records, cancel in the subscription portal and email us.
