Privacy

Last updated 19 October 2026

Short version: this site has no accounts. Your gear, builds and settings stay in your own browser. The site shows ads from Google, which uses cookies (see below).

What stays in your browser

The site saves your stash, your builds, your saved builds and your settings in your browser's local storage, so they are still there next time. They are never sent to us. To delete all of it, clear this site's data in your browser settings (Clear in the site's header empties just your stash and custom build).

Save files

When you import or sync a Minecraft Dungeons save file, it is read and decrypted on your own device: in your browser, or by the optional sync helper running on your own computer. The save file is never uploaded anywhere.

Share links

A share link holds the build in the address itself. Anyone you give the link to can see the build. When a share link is opened, our server reads the build from the address only to draw the link preview; it isn't stored.

Services the site uses

Advertising and cookies

The site shows ads served by Google AdSense, which pays for the site. Google and its partners use cookies and similar technology to show ads, limit how often you see the same ad, measure how ads perform and, where you allow it, show ads based on your visits to this and other websites.

Apart from the ads, the site uses no cookies and no analytics.

Children

The site doesn't ask anyone for personal information, so it collects none from children either.
