Cookie policy
What this website stores on your device, and why. Last updated: 21 October 2026.
In short
This website works without cookies. The only optional cookies are HubSpot's analytics cookies, which help us see which pages are visited. They are set only if you accept them in the banner shown on your first visit. You can change your choice at any time with Cookie settings at the bottom of every page.
A cookie is a small text file that a website stores in your browser. Session cookies are deleted when you close the browser; persistent cookies stay until they expire or you delete them.
Cookies this website sets
We checked the cookies below in a browser on 21 October 2026. Durations are as set by the provider at that date; providers can change them, and we review this list when they do.
Strictly necessary
| Cookie | Set by | Purpose | Expires |
|---|---|---|---|
cf_clearance | Cloudflare | Records that your browser passed Cloudflare's automated check against bots, so the site does not have to challenge you on every page | 1 year |
__hs_cookie_cat_pref | HubSpot (cookie banner) | Remembers the choice you made in the cookie banner, whether you accepted or declined | 6 months |
Analytics (only after you accept)
| Cookie | Set by | Purpose | Expires |
|---|---|---|---|
__hstc | HubSpot | Records your first, last and current visit and a session count | 6 months |
hubspotutk | HubSpot | Identifies your browser to HubSpot. If you submit a form, it is sent with your request so that your enquiry can be connected to your earlier visits | 6 months |
__hssc | HubSpot | Counts page views within a session | 30 minutes |
__hssrc | HubSpot | Notes that a new session has started | When you close the browser |
Set by other websites while this one loads
The cookie banner and, after consent, the analytics script are loaded from HubSpot's servers. Those servers are protected by Cloudflare, which may set a short-lived __cf_bm cookie (30 minutes) on HubSpot's own domains. That cookie belongs to HubSpot's sites, not to pixenbio.com, and is used only to tell browsers from bots.
Stored in your browser, but not a cookie
When you submit a form, we keep your e-mail address in your browser's session storage until you close the tab, so that other forms on the site do not ask for it again. It is never sent anywhere else and is deleted when the tab closes. Select Not you? under a form to remove it straight away.
The bot check on our forms
When you submit a form, Cloudflare Turnstile checks that the request comes from a person. On this site it sets no cookie of its own and stores nothing on your device. The result of the check is sent to our server once, with your submission.
What we do not do
Our fonts and images are served from this website, so loading a page contacts no font or image providers. The website embeds no videos, maps, social media buttons or advertising, and sets no advertising cookies.
Managing cookies
Cookie settings at the bottom of every page reopens the banner, where you can accept or decline analytics cookies. You can also delete or block cookies in your browser's settings; blocking all cookies does not stop this website working.
If this changes
If we add a tool that uses cookies, we will ask for your consent before it runs and list it on this page.
