What stays on your device
Two things are saved, and both stay in your browser: the theme you choose and what you enter in the limit tool. Nothing is sent to this site or anywhere else.
The home page carries paid links, marked Ad, to one online casino partner. Each one opens in a new tab. Your browser does not pass along the page you came from, so the partner cannot see which page sent you. The site earns a commission from those links, and the partner can change. Inner pages, including this one, carry no paid links at all.
