Privacy Policy

Last updated: September 7, 2026

What we collect

• Account data: a display name; optionally a username (email) and a hashed password if you register. Guests get a random account id.
• Gameplay data: match results, card collection, trophies/ELO, guild membership — the stuff the game needs to function.
• Purchase data: if you buy something, Stripe processes your payment. We never see or store your card number. We store the product bought, the amount, and Stripe's transaction id for support and fraud prevention.
• Technical basics: server logs with IP addresses (kept briefly for abuse prevention), and a session token in your browser's localStorage so you stay signed in.
• Analytics: Google Analytics counts visits — which pages get opened, what linked to them, and roughly which country you're in. It sets a first-party cookie called _ga so a returning visit isn't counted twice. In the UK, EU and Switzerland that cookie is not written until you say yes, and we remember your answer; anywhere else it starts on and you can switch it off below. That's the only thing on the site that isn't ours. Google's advertising features are disabled on every page: no ad profiles, no advertising trackers, no selling of data — ever.

How it's used

To run matches, save your progress, deliver purchases, prevent cheating and abuse, and answer support requests. That's it.

Sharing

Payment processing: Stripe (and the relevant app store if you buy on Steam, iOS, or Android). Analytics: Google, which receives the page you opened, the page that referred you, and your IP address. Hosting: our game servers in the EU/US. We share data only when required to provide the service or by law.

Your choices

— or just use an ad blocker, or Google's opt-out add-on. Nothing in the game breaks without the tag. You can play as a guest with no email. To delete your account and its data, email [email protected] from the account's email (or include your player id) — we delete within 30 days, except records we must keep for tax/fraud purposes.

Children

The game is intended for players 13 and older. We do not knowingly collect personal information from children under 13; contact us for removal.
