What this covers
This policy explains the cookies and similar browser storage we use on peptx.co.uk, what each one is for, and how you can control them. It sits alongside our Privacy Policy, which explains how we handle personal data more broadly.
Strictly necessary storage
These are required for the site to work. Without them you could not sign in or keep items in your basket, so they are not optional and do not require consent.
| Name | Type | Purpose | Retention |
|---|---|---|---|
peptide-cart | Local storage | Keeps the items in your basket between visits | Until you clear it or your basket empties |
peptide-cart-version | Local storage | Tracks the basket format so older baskets upgrade cleanly | Until cleared |
peptx_lang | Local storage | Remembers your language choice | Until cleared |
peptx_app_version | Local storage | Detects when a new version of the site has been released | Until cleared |
| Supabase authentication token | Local storage | Keeps you signed in to your account | Until you sign out or it expires |
session-id | Cookie | Maintains your browsing session | Session |
__dpl | Cookie | Set by our hosting provider to route requests correctly | Session |
Analytics
We record basic usage information, such as which pages are viewed, in our own database on our own infrastructure. This is first-party, is not sold or shared, and is not used to build advertising profiles or to track you across other websites.
Advertising
We include Google Ads conversion tagging on the site. Our advertising is not currently running, and no advertising cookies are being placed. If we resume advertising we will ask for your consent before any advertising or measurement cookies are set.
Controlling cookies
You can delete or block cookies and clear local storage through your browser settings. Every major browser offers this under its privacy or site data settings.
Blocking strictly necessary storage will stop parts of the site working. In particular you will not be able to stay signed in or keep a basket.
Changes
If we change what we store, we will update this page and change the date at the top.
