Calculated Carnage ("the game") is a free browser game made by Calvin Blann. This page explains what information the game uses and why.

Information stored on your device

The game saves a few things in your browser's local storage so they're there next time: the player name and color you choose, your match setup, saved games, and whether sound is muted. This stays on your device. We don't receive it, and you can clear it at any time by clearing your browser's site data.

Online play

If you use Online Play, the name, color, chat messages and game moves you send are relayed to the other players in your room through free public relay servers (HiveMQ and EMQX). Nothing is stored after the match, but anyone who knows a room code could see that room's messages, so don't put personal information in your player name or chat.

Advertising

The game is free because it shows ads served by Google AdSense. Google and its partners use cookies to serve ads based on your previous visits to this and other websites. Google's use of advertising cookies lets it and its partners serve ads based on your visits to this site and/or other sites on the internet.

You can opt out of personalized advertising by visiting Google Ads Settings, or opt out of many third-party vendors' use of cookies at www.aboutads.info. To learn more, see how Google uses information from sites that use its services.

Visitors in the European Economic Area, the UK and Switzerland will be asked for consent before personalized ads are shown.

Children

The game doesn't ask for names, emails, or any account. It isn't directed at children under 13, and we don't knowingly collect personal information from them.

Changes

If this policy changes, the date at the top of this page will be updated.
