This is Tesserix's general policy. Individual products may publish their own — Fe3dr, for example, maintains its own policies at fe3dr.com.

What cookies are
Cookies are small text files stored on your device by your browser. We use them, and similar technologies like local storage, to make our products work and to understand how they're used.

We don't use advertising cookies or sell data collected through cookies.
