Cookie policy

What cookies are

Cookies are small text files a website stores in your browser. We keep their use to a minimum and ask for your permission before using any cookie that is not strictly necessary.

Strictly necessary cookies

These are always on because the website cannot work without them.

• sessionid: keeps you signed in and remembers documents you started as a guest. Deleted after 30 days of inactivity.
• csrftoken: protects forms against forgery. Kept for one year.
• bacc_consent: remembers your cookie choice so we do not ask on every page. Kept for six months.

Analytics cookies (optional)

• bv_id: a random identifier used to count unique visitors and page views. It does not contain your name or contact details. Kept for one year. Set only if you accept analytics cookies.
• If our administrators enable Google Analytics, Google's analytics cookies are also set, only after you accept analytics cookies.

Preference cookies (optional)

• django_language: remembers your language on this device after you close the browser. Kept for one year. Without this permission your language is remembered only while you are signed in or until your session ends.

Marketing cookies (optional)

• If we run advertising campaigns and our administrators enable a marketing pixel (for example Meta), its cookies are set only after you accept marketing cookies. No marketing cookies are used otherwise.

Changing your choice

Use the Cookie settings link at the bottom of every page to change your choice at any time. You can also delete cookies in your browser settings. When we change this policy we ask for your choice again.
