Cookie information.

The two cookies Persian Demantoid uses to keep you signed in, and why there are no tracking cookies.

No tracking

We do not use advertising, analytics or third-party tracking cookies.

Cookies we use

pd_session — keeps you signed in (only after you sign in). Secure, HttpOnly, expires after 7 days of inactivity or when you sign out.

pd_signed_in — a simple “signed in” flag so pages can show your account menu. Contains no personal data.

Browser storage

The site remembers small preferences on your own device only: whether you have already seen the opening animation in this session, and the boxes you tick in the buying checklist. Nothing is sent to us.

Your choice

You can delete cookies in your browser settings at any time; you will simply be signed out.
