Cookie Policy
Last updated: October 3, 2026
We keep this short. Research use only — this catalog is for laboratory research, not human use.
Essential cookies
Always on. They keep the cart, session, and age-gate working. Without them the site cannot function. If you sign in to your account, a sign-in cookie (__Host-blr_acc) keeps you signed in for up to 90 days; it is not used for tracking.
Analytics
Google Analytics 4 (measurement ID on this site) runs only after you choose Accept on the cookie bar. If you choose Essential only, we do not load analytics.
Advertising measurement
We advertise on Meta (Facebook and Instagram). To measure those ads, tags on this site send your shopping activity (products viewed, cart changes, starting checkout, completed orders) to Meta, and may set cookies and identifiers such as _fbp and _fbc. They run on every page except the checkout page, unless you choose Essential only: then they do not load and nothing more is sent. Details are in section 5 of our Privacy Policy.
What we do not do
We do not sell your data for money. We never send card details to advertising or analytics services, and no advertising tag runs on the checkout page.
Your choices
Use anytime to Accept analytics, or to keep Essential only, which switches analytics and advertising measurement off. See also our Privacy Policy.
