Cookie policy

Cookies are small text files a website leaves in your browser so it can recognise the same visitor again. We keep ours to a minimum. Most exist simply to remember that the order form on the page for Cystobact was already filled in, and to count visits so we can see which sections people read to the end. None of them holds your name, your phone number or any payment information.

The types we use

• Necessary — keep the page working as you move through it: remembering that the form was submitted, that a notice was closed, or which accordion you opened.
• Preference — remember choices such as the language version of the site you arrived on, so you are not sent back to the wrong one.
• Statistical — count visits and page views in aggregate. They tell us that a section is read or skipped; they do not tell us who read it.

How long they last

Session cookies disappear the moment you close the browser. The rest are short-lived and expire on their own after a limited period, or as soon as you clear your browsing data — whichever comes first.

Turning them off

Cookies are controlled by your browser, not by us, and every browser lets you block or delete them. In Chrome, Edge and Firefox the setting sits under privacy and security, where you can clear browsing data or refuse cookies from particular sites. In Safari the equivalent option is under privacy, including the choice to block them all. Blocking everything is your right, but be aware that a form which cannot remember its own state may behave oddly.

Other people's cookies

If a video is embedded on a page, playing it may set cookies belonging to the video service. That only happens once you click play, and those cookies are governed by that service's own rules rather than ours.

Asking us about this

If you would like to know exactly what is stored during a visit, email [email protected] and we will tell you. This policy reflects how the site works in 2026.
