Privacy policy
Last updated: 21 October 2026
What we store
- Game rooms. The name you type, the cards you pick, and the questions and answers in your game are stored on our server so other players in your room can see them. Rooms are deleted automatically 24 hours after the last move.
- Your browser. Your current game session, your notes and which cards you have flipped are saved in your own browser (session and local storage). They never leave your device, and you can clear them in your browser settings.
We don't ask for accounts, emails or passwords, and we don't sell your data.
Analytics
We use Vercel Web Analytics to count page views. It doesn't use cookies and doesn't identify individual visitors.
Advertising and cookies
We show ads through Google AdSense to keep the game free. Google and its partners use cookies to serve ads based on your previous visits to this site and other sites.
- Read how Google uses information from sites that use its services.
- You can turn off personalised ads in Google's My Ad Center, or opt out of many third-party ad vendors' cookies at aboutads.info.
- If you are in the EEA, the UK or Switzerland, you'll be asked for consent before personalised ads or ad cookies are used, and you can change your choice at any time from the privacy link Google shows on the page.
Third parties
- Vercel hosts the site and may log technical data such as your IP address for security and to keep the site running.
- MongoDB Atlas stores game rooms.
- Google AdSense serves ads, as described above.
- Google Fonts supplies the title font, so your browser requests it from Google's servers.
- Card images load from Supercell's servers, and the "Open wiki page" link goes to the Clash Royale Fandom wiki. Those sites have their own privacy policies.

If anything here changes, we'll update this page first.
