We keep cookies to a minimum. This page lists every cookie the site sets, what it does, how long it lasts, and whether it is optional.
Strictly necessary
- aa_session — a random session identifier used to keep you logged in to admin areas. Lifetime: browser session. Set only on login. Cannot be disabled.
- aa_csrf — a cross-site-request-forgery token for form submissions. Lifetime: browser session. Cannot be disabled.
Preferences
- aa_theme — remembers whether you chose light or dark mode. Lifetime: one year. Optional.
- aa_cookie_consent — records your cookie preferences so we don't ask again. Lifetime: one year.
Analytics (optional)
Set only if you accept analytics cookies through the banner.
- aa_ga — anonymised session identifier for aggregate page-view tracking. Lifetime: 30 days.
Third-party cookies
We do not set advertising cookies. We do not embed social-network share-and-track widgets. If we embed a third-party video or tweet, a cookie may be set by that provider only after you click to play — we use facade loaders where possible to prevent that until you click.
Changing your choice
Clear your browser cookies for this site and reload the page to see the banner again. Or email privacy@alvernoalpha.com.
