This site does not ask you to register and does not collect names, addresses or payment details, because there is nothing here to buy and no account to hold.
What is collected is limited to ordinary web-server information and aggregate analytics: which pages were requested, roughly where the request came from, and which browser was used. That data is used to understand which parts of the catalogue are worth expanding and to notice when something is broken.
Embedded games and advertising are separate. Each game is served by its own provider, and advertising is served by a third party; both may collect information under their own policies when their content loads on a page you visit. We do not receive that data in a form that identifies you.
If you contact us, we keep your message and your address only for as long as it takes to answer, and we do not add either to any mailing list.
