Cookie policy

The portal sets cookies only for signing in and for rejecting forged requests. There are no advertising cookies and no third-party analytics cookies.

Session

A session cookie keeps you signed in. It is encrypted, sent only to this site, and removed when you sign out or when the session expires.

Security token

A second cookie helps the portal reject requests that were not made from a page on this site. It holds no personal information.

Map tiles

Opening the network map loads map tiles from OpenStreetMap. That request is separate from these cookies.
