Nothing you do here reaches a server of ours, because there is no server of ours. Every simulation runs inside your browser, and your settings and any picture you load are written to your own machine and never leave it. There is no account and nothing to sign up for.

Display settings, the speed and size you last used for each program, which programs you have opened, and a shrunken copy of any photo you loaded. All of it sits in your browser under this address. Clearing site data deletes it, and nothing is left anywhere else.

Anything you type or load becomes a starting screen inside the page and is never sent anywhere. A photo is kept for the programs that share it, shrunk to 256 pixels and held in your browser. Clearing site data removes it.

Cloudflare serves the site and sees the request logs any host would see. Visitor counts come from Cloudflare Web Analytics, which sets no cookies and identifies nobody. Ads are not running yet. Once they are, the ad vendors, Google among them, may set cookies and use visits to this and other sites to pick what to show. That can be turned off at google.com/settings/ads.
