This page explains what cookies and similar storage Anthia uses, and why.
What is a cookie
A cookie is a small text file stored on your device by your browser. Some cookies are essential to make a website work; others track you across sites for advertising. We only use the essential kind.

Local storage is not transmitted to our servers; it lives only in your browser.
