This game is made to be played, not to collect your data. This page explains in plain words what is stored, what is measured and what you can change.
Stored on your device
Your progress (level, Funds, trophies, card levels), your deck and your settings (sound, blood and your analytics choice) are saved in your browser's local storage. They stay on your device unless you create an online account. Clearing your browser data removes them.
Accounts
An account is optional. If you create one we use the email address, username and avatar you give us, and your progress (trophies, XP and match stats), so that your profile, the leaderboard, friends and likes can work. Passwords are handled by the sign-in service and are never visible to us. Your username, avatar and stats can be seen by other players; your email cannot.
Analytics (only if you accept)
We ask once whether we may use anonymous analytics. If you accept, we load Google Analytics, Microsoft Clarity and Sentry (crash reports). They use cookies or similar identifiers to count visits and show how the game is played, for example which screens are opened, whether the tutorial is finished and how matches end. Clarity can also record how a session looked and where taps and clicks happened, so we can find confusing screens. Sentry receives technical details when the game crashes, such as the error, your browser and device type and the page you were on. We do not send your name or email to any of these services.
If you decline, none of these services is loaded and nothing is sent. Their own policies cover how they handle the data: Google (policies.google.com/privacy), Microsoft (privacy.microsoft.com) and Sentry (sentry.io/privacy).
Your choice now: not chosen yet.
What we do not do
We do not sell your data, show ads or use your data for anything other than running and improving the game.
Children
The game is not aimed at children under 13 and we do not knowingly collect data from them.
Your rights
Depending on where you live you may be able to ask what we hold about you, ask us to correct or delete it, or withdraw your consent at any time (use the button above). Use the contact details below.
