Blog

sessionid: Maintains your login session and authentication state
csrftoken: Security token to protect against cross-site request forgery attacks
django_language: Stores your language preference for the interface
seen_posts: Remembers which blog articles you have opened, so the "New" label disappears once you have read them. Contains only article numbers — no identifier and no tracking.

Splitting bills, reading receipts, and keeping track of what everyone owes.
