Chernobyl — what we collect, what we don't

Chernobyl is a single-player game with a public global leaderboard. This page describes the only data the game ever sends to a server, and what happens to it. Plain language.

What is collected

When you finish a run and press SUBMIT on the death screen, the game sends three things to chernobyl.ximg.app:

• The 3-character initials you typed, plus the run stats: final score, kills, wave reached, weapon held, run duration, pickups grabbed, shots fired, damage dealt.
• An input replay file (a few KB): a binary log of the keys, mouse deltas, and timing for the run, so the website can replay the run frame-for-frame. No screen capture, no audio, no system data.
• A short video recording of the gameplay session (~30-50 MB, MP4): captured directly from the game's renderbuffer and the game's mixed audio output. No webcam, no microphone, no system audio outside of the game.

If you press SKIP or ESC on the death screen, nothing is sent.

What is NOT collected

• No name, email, phone, or contact info.
• No device identifiers (IDFA, advertising ID, MAC address, IP-derived location).
• No analytics, no tracking pixels, no third-party SDKs.
• No tracking across sessions, apps, or websites.
• No microphone access, camera access, or contacts access.
• The game does not collect data about children. It is rated 17+ for violent content.

How long it's kept

Submitted scores, replays, and videos are stored on chernobyl.ximg.app indefinitely as part of the public leaderboard. Anyone can view them at /scores.html and /watch.html.

Server logs

The web server (nginx) keeps standard request logs containing IP address, user-agent, and request path for normal operational purposes (debugging, abuse detection). These are rotated and discarded on a rolling schedule and are not linked to your in-game initials or scores.

Your control

• You can play the entire game without submitting anything: skip the initials prompt and no data leaves your machine.
• To request deletion of a previously-submitted score (and its replay/video): email rapidvps@gmail.com with the initials and approximate timestamp of the run. We'll remove it within a few days.

Third parties

The game itself does not contact any third-party services. The website at chernobyl.ximg.app is self-hosted by the developer. The macOS download is delivered directly from the same origin. There is no advertising, telemetry, or analytics provider involved.

Changes

If this policy changes materially, the date below will update and the change will be noted in the next app release notes.
