What a cookie is
A small file the site asks your browser to keep, so it can recognise your session on the next page.
The categories we use
- Strictly necessary. Your session, the sign-in cookie and the anti-forgery token. The tool cannot work without these, so they are always on.
- Preferences. Remembers your chosen country, currency and list settings.
- Analytics. Aggregated, anonymised usage counts so we can see which parts of the tool people struggle with.
- Marketing. Off by default. Only set if you switch it on.
Changing your mind
Open cookie preferences at any time. Your choice is stored for six months, and we ask again if this policy changes.
Blocking cookies in your browser
Every major browser lets you block or delete cookies in its settings. Blocking the strictly necessary ones will stop you signing in.
