Xilliz ("we", "us") operates the websites and apps listed above. This policy explains what we collect and how it is used. Last updated: July 2026.
No accounts, no personal data. You do not register or log in to use our Magic Arena websites. We do not ask for your name, email, or any personal identifying information to let you vote.
Voting protection. To stop the same match being voted on twice, we store an anonymous identifier in your browser and record a one-way hashed value derived from your connection. We do not store your raw IP address, and these values cannot be used to identify you personally.
Advertising and cookies. We use Google AdSense and Google AdMob to display ads. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. You may opt out of personalised advertising by visiting Google Ads Settings, or opt out of some third-party vendors' cookies at aboutads.info/choices. Where required, we ask for your consent before personalised ads are shown.
Affiliate links. Some pages may contain affiliate links (for example to Amazon). If you buy through them, we may earn a small commission at no extra cost to you.
