The short list of cookies this catalog site sets, what each is for, how long it lives, and how to turn it off.
Effective date: May 16, 2026
A cookie is a small text file a website tucks onto your device — computer, tablet, or phone — when you visit. It lets the site recognize that device next time, remember a preference, hold your session together, and (with permission) measure how the site is used. Related technologies — local storage, session storage, web beacons, pixel tags — do similar jobs and are covered here too.
Some of these we set ourselves (first-party); some are set by providers we engage (third-party). Every third-party cookie on the Site is named in the table further down, with its provider and purpose.
We group cookies into four kinds. By default the Site loads only the first two; everything else waits for your opt-in.
Strictly necessary — what the Site needs to run at all: secure routing, session integrity, language detection, and remembering that you dismissed the announcement bar. Our preference controls can't switch these off because the Site depends on them.
Functional — these remember preferences (such as your locale) so the Site behaves the same across visits. Helpful, not essential.
Analytics — these help us see, in aggregate, how the Site gets used. We run Google Analytics 4 with IP truncation (anonymize_ip), no PII passed, and advertising cookies disabled, alongside cookieless Vercel Analytics. You can block both in your browser; we don't currently show a cookie banner because our audience is professional B2B buyers and the analytics scope is strictly anonymized.
Marketing / advertising — we don't run advertising or retargeting here, so no marketing cookies are set. If that ever changes, we'll update this policy and put a consent banner in front of any marketing tag before it loads.
Here's the current inventory — the cookies and similar technologies in use, including the ones that appear only if you opt in to analytics. We refresh this table whenever we switch providers or add or drop a tag.
| Cookie / key | Provider | Purpose | Duration | Type |
|---|---|---|---|---|
| peptidexpo_announcement_dismissed | PeptideXpo (first-party) | Remembers that you have dismissed the top announcement bar. | 30 days | Strictly necessary |
| peptidexpo_locale | PeptideXpo (first-party) | Remembers your preferred language when multi-language is enabled. | 1 year | Functional |
| _vercel_* | Vercel (Vercel Inc., USA) | Edge routing, deployment protection, anti-abuse. Cookieless analytics where possible. | Session up to 1 year (varies by sub-cookie) | Strictly necessary |
| _ga, _ga_* | Google Analytics (Google LLC, USA) | Aggregate visitor counts, sessions, traffic sources, and engagement events. Anonymized IPs. | Up to 24 months | Analytics |
We update this table when we change providers, add or remove tags. Some cookies (e.g. Google Analytics) load only after explicit opt-in.
Strictly-necessary and functional cookies go in without asking, because they either keep the Site running or deliver something you explicitly requested (like remembering your language).
Analytics — and any future marketing cookies — load only after you give clear, affirmative opt-in consent through a banner. You can pull that consent back any time by using the consent-management link in the footer (where shown) or simply clearing your cookies.
If you're in the European Economic Area, the United Kingdom, or a jurisdiction with comparable rules, no analytics cookie loads at all unless you've actively opted in.
Every mainstream browser lets you view, block, or delete cookies. The steps differ, but the relevant help pages are:
Blocking strictly-necessary cookies can break parts of the Site. Blocking analytics or marketing cookies changes nothing about how the Site works — it just takes you out of our aggregate measurement.
If Google Analytics is on and you'd opted in, you can opt back out later with Google's official Analytics opt-out browser add-on, or by clearing the _ga / _ga_* cookies. Two browser signals we respect automatically: send the Global Privacy Control (GPC) and no analytics or marketing cookie is set even after consent; send a Do-Not-Track (DNT) header and — though there's no agreed industry standard for DNT — we read it as a withdrawal of consent for analytics and marketing cookies, in line with current best practice.
We update this policy when we add or remove cookies, change providers, or respond to a regulatory shift; the Effective Date at the top always reflects the latest revision.
