What is stored

Your progress, stars, unlocked scenes and settings live only on your own device. In the browser version they are written to IndexedDB; if the browser denies IndexedDB they fall back to local storage, and failing that they stay in memory only for as long as the tab is open.

This is the whole of it: which levels you finished, in how many moves, which stars and traces you collected, the move sequence of a level left half-played, and your settings (language, sound levels, reduced motion, text size, threat highlighting). No name, e-mail address, device identifier, location, IP address or usage statistic is kept anywhere.

Network activity

In the browser version the network is used at exactly two moments: when you first open the page, and when the service worker downloads a new version. After that, pages, scripts, artwork and sounds all come from your device's cache — the behaviour in airplane mode is identical. No request goes to an external domain: there are no font, analytics, CDN or ad-server connections.

Moving your save

The export button in the settings menu hands you your save as a versioned JSON text; you can copy it or download it as a file. Import reads that text back and, if it is valid, replaces your save; an invalid text changes nothing. You are the one moving the file — it is never uploaded to a server.

Deleting your data

There is no address to send a deletion request to, because we are not the ones holding the data. Clearing the site data in your browser (or uninstalling the app) erases your save completely. That cannot be undone, so export it first if it matters to you.

The mobile version

The iOS and Android versions follow the same principles: data is kept in the device's own storage (AsyncStorage), the game makes no network requests while you play, and it asks for no system permissions such as location, contacts, camera or microphone. Uninstalling the app removes the data with it.
