What cookies are
Cookies are small files that a website stores on your device. Some are needed for the site to work. Others help us understand how the site is used.
This policy explains which cookies and similar technologies this website uses. It covers dosium.com only. For how we handle personal data more widely, see our Privacy policy.
Cookies we use
We use one analytics tool, PostHog, to understand how the site is used so we can improve it. UK law allows this without asking first, as long as we tell you about it and make it easy to opt out.
ph_phc_…_posthog is set by PostHog. It recognises your browser across visits so we can see which pages are viewed and how people move around the site. It lasts up to one year. PostHog stores this data in the EU.
PostHog may also record how pages are used, such as clicks, scrolling and mouse movement, to help us find problems. What you type into forms is masked and not recorded.
Google Tag Manager loads PostHog. It does not set cookies itself.
If you opt out, PostHog stores a small cookie so it remembers your choice.
We do not use advertising or marketing cookies, and we do not share analytics data with anyone for their own purposes.
Your choices
You can opt out of analytics at any time using “Opt out of analytics” in the footer of any page.
You can also block or delete cookies in your browser settings. The site will still work if you do.

We will update this policy when we change the tools we use. The date at the top shows when it last changed.
