This Cookie Policy explains how Forty Two A - Research and Development Ltd. ("42A," "we," "us") uses cookies and similar technologies on 42a.ai. It should be read together with our Privacy Policy.
What cookies are
Cookies are small text files a website stores in your browser. Similar technologies, such as pixels and scripts, work the same way. Some are set by us (first-party) and some by the services we use (third-party).
Your choices
When you first visit, a banner lets you accept, reject, or choose cookies by category. If you are in the EEA, UK or Switzerland, analytics and marketing cookies stay off until you accept them. Elsewhere they are on by default and you can turn them off at any time. A Global Privacy Control signal from your browser turns marketing cookies off.
You can change your choice whenever you like through Cookie settings at the bottom of every page. You can also block or delete cookies in your browser settings, although some parts of the site may then not work as expected.
