Quad Chase is a browser game at quadchase.com. It has no accounts and collects as little as possible.
Game preferences and progress (theme, sound, skins, best scores, round checkpoints) are kept in your browser's local storage. They never leave your device unless listed below and are erased if you clear site data.
On quadchase.com we use Vercel Web Analytics to count page views and see which site a visit came from (for example, a link on Reddit). It sets no cookies, does not track you across other websites, and does not build a profile of you. We see totals, not individuals.
This runs only on quadchase.com. It is not included in the Android app, and not when the game is played on a portal such as CrazyGames.
When you create a disc it is registered with us and given a code. After that, when a run ends, the game sends a short summary of it — the disc's name and colour, its stats, coins, skills, arena depth and PVP record, and your best scores. We use this to see how the game is being played. Your descent in progress and everything else stay on your device.
That same request tells us the country (and, where the network reveals it, the city) the run came from. This is worked out from the connection by our host, Vercel; we do not store your IP address and we do not use a location service.
Pressing SAVE in the den is separate, and is the only thing that creates something you can restore from — a full copy, including the descent you are part-way through. A disc that has only been registered cannot be restored.
It is a backup, not an account: there is no email, no password and no login. The code is the only key, so anyone who has it can restore that profile — keep it to yourself. Pressing SAVE again overwrites the same code.
The only personal information involved is whatever you typed as the disc's name, so don't use your real name if you'd rather it not be stored. To have a disc and its backup deleted, send us the code: team@quadchase.com.
Phone-controller and party modes connect devices directly to each other (WebRTC). A public broker service (PeerJS) is used only to introduce the devices; game traffic flows peer-to-peer and is not stored.
The Android app shows ads through Google AdMob. AdMob may use your device's advertising ID and device information to serve and measure ads, under Google's privacy policy. You can reset or delete your advertising ID in your device's Google settings.
When Quad Chase is played on game portals (such as CrazyGames), ads are served by that portal under its own privacy policy.
quadchase.com is adding Google AdSense. Ads are not serving on the site yet; once they begin, Google and its partners may use cookies and device information to show and measure them, under Google's privacy policy. Visitors in the EEA, the UK and Switzerland are asked for consent before any such cookies are set, and can decline.
