Crystal Evolution — Privacy

Effective 2026-11-01. Last verified against the game's code: 2026-11-01. This page adds detail to the Responsive Design LLC Privacy Policy.

In short: No account. We (Responsive Design LLC) collect no personal information from this game. Your progress and settings are saved only on your device. No ads, no analytics. Optional online co-op connects players directly, which shares your IP address and chosen display name with the other players and the connection services.

What is stored on your device

Game progress, high scores, unlocks and settings (volume, accessibility toggles) are saved in the browser's localStorage (web) or the app's private storage (Android). They never leave the device; clearing site data / uninstalling deletes them.

What leaves your device

  • Web version (itch.io): nothing is sent by the game itself. It only loads its own files from the site that hosts it (itch.io, under itch.io's own privacy policy). The built-in analytics module is switched off in published builds — it creates no identifier and makes no network requests.
  • Android app (not yet released): nothing except the optional multiplayer described below. No ads, no analytics.
  • Optional multiplayer: optional peer-to-peer co-op (WebRTC via PeerJS). Shares: room code, a display name the player chooses (random by default), game commands/state, and — inherently — each device's IP address/network candidates. Recipients: other players in the room; PeerJS public signalling broker (0.peerjs.com); Google public STUN server; PeerJS public TURN relay (only if a direct link fails).

Purchases

There are no in-app purchases. Everything is earned by playing.

Analytics

Off. Published builds send no usage statistics. If that ever changes, this page will be updated first, the data will be anonymous gameplay events only (no name, email or device fingerprint), browsers' "Do Not Track" / "Global Privacy Control" signals will be honoured, and there will be an opt-out in Settings.

Children

This game is not directed at children under 13, and we do not knowingly collect personal information from children. The game collects no personal information from anyone.

Your choices

  • Delete your saved progress by clearing this site's data in your browser, or by uninstalling / clearing storage for the Android app.
