Effective September 23, 2026. 403 Town is published by LULS. Contact zerobyewaste@proton.me.

Offline play

Campaign saves, settings, and Endless Wave records stay on your device. The game has no advertising, analytics SDK, in-app purchases, or account registration.

Update checks

On startup, the game requests the public release manifest from luls.lol to check for a newer build. It sends no save data, player identifier, or gameplay history. The hosting service receives normal connection information such as your IP address. Choosing Download opens the platform build in your browser. Offline play remains available if the check fails.

Online VS

The arena server processes your network address, character selection, room code, and gameplay inputs to run your match. It sends match state to the other player. There is no chat, player-name entry, profile, or email collection. Match data is held in memory and discarded when the room closes. We do not use it for advertising.

Website and downloads

Our hosting service processes connection information needed to deliver this site and downloads, including IP addresses and request information in server logs. This site has no advertising or tracking cookies. Stores process information under their own privacy policies.

Your choices

Campaign, Training, CPU VS, and Endless Wave work without connecting to the arena server. Uninstalling removes local data according to your device settings. Email support with privacy questions or requests about information you have sent us.
