Cookies

Only the storage strictly necessary to operate the site is used.

Pre-launch — this notice will be replaced before commercial activity begins.

Strictly necessary storage

When you sign in to a client account, the session is kept in your browser's local storage so that you remain signed in between pages. Signing out removes it.

Optional measurement

With your agreement, Google Analytics measures in aggregate which pages are read, so that we can improve the catalogues and the Encyclopedia. It is loaded only after you have agreed: if you refuse, or before you choose, nothing is requested from Google at all.

No advertising cookies, no advertising identifiers and no cross-site profiling are used, and no information that identifies you is sent. You may change or withdraw your choice at any time from the footer.

Managing storage

You can clear site data at any time through your browser settings. Doing so signs you out of your client account. Questions about this notice, or requests for technical assistance, may be sent through the contact form.
