Privacy Policy
Last updated · 28 July 2026Your game files and saves live in your browser. We only store something on a server if you choose to sign in.
Stays on your device
Mod files, base games, engine settings and — if you're not signed in — your saves are kept in your browser's private storage. They never reach us and we can't read them.
Stored on our server, only if you sign in
- The basics from Google sign-in: email, name, avatar, plus a public handle you can change.
- A list of your builds — the name and which files each one uses — and, with cloud sync on, your save files so they follow you between devices.
- The bare operational records needed to keep you signed in.
Cloud sync can be turned off any time in your profile. Anything already in the cloud stays until you delete it.
Analytics
We count page visits and how long a page was open. No IP address, no browser fingerprint, nothing from your game files or saves. If Google Analytics is switched on, the cookie banner asks first, and declining leaves it off.
Advertising
The play screen can carry ads. They're served by Freestar, which also runs the consent dialog you'll see before anything personalised loads — your answer there is what decides whether ad partners can use cookies or an ad ID. We don't hand them your account, your builds or your saves; an ad partner sees only what any site's ads see: the page, the device and whatever you consented to. The rest of the site carries no ads.
Other services we rely on
Signing in goes through Google, under their own privacy policy. Base game files are downloaded by your browser from public archives, so those archives see the request the same way any website you visit does. Avatar images are proxied through us so your IP never reaches the image host.
Deleting things
From your profile you can change your handle, turn off cloud sync, wipe your cloud saves, or delete the account outright — which removes your builds and saves from our side for good.
