Cookie Policy
Version 0.4 · Last updated 7 November 2026 · Follows Bilcor Group policies v0.6 · Draft for legal review
This page lists every cookie and every item of browser storage that Common Ground UK uses, and why. Read it alongside our Privacy Notice.
The short version
- We use no advertising cookies and no tracking pixels.
- We count visits anonymously, without cookies, so we know which pages are used. You can switch this off below.
- Everything else listed below is needed for a feature you chose to use, so the law does not require a consent banner.
- Most items are kept in your browser’s local storage rather than as cookies. They are never sent to anyone else.
Used by everyone
| Name | Type | Purpose | How long |
|---|---|---|---|
| cg_consent | Local storage | Remembers that you gave explicit consent and confirmed you are 16 or over, and which version of the wording you agreed to, so we do not ask before every answer | Until you clear your browser data, or until the wording changes |
| cg_session_id | Local storage | A random identifier so the platform knows which questions this browser has already answered, and so one browser gets one say per question | Until you clear your browser data |
| cg_profile_done | Local storage | Remembers that you have answered or skipped the optional profile, so you are not asked again | Until you clear your browser data |

Third parties
Our fonts are served from our own website. Your browser does not contact Google Fonts or any other font service.
Payments by organisations are made on Stripe’s own checkout page, which sets its own cookies under Stripe’s cookie policy.
Analytics
We use Vercel Web Analytics to count visits. It sets no cookies and stores nothing on your device. Each visit is recognised only by a scrambled code made from the request, which is thrown away after 24 hours, so we see totals (pages viewed, where visitors came from, country, device and browser type) and never an individual.
UK law allows this kind of measurement without asking first, as long as we explain it and you can easily object. To object, use the switch below. It applies to this browser.
We also do not count you if your browser sends a Global Privacy Control or Do Not Track signal. Sign-in, account, admin and embed pages are never counted, and anything personal in a web address (such as a sign-in or unsubscribe code) is removed before a visit is counted. More detail is in our Privacy Notice.
Managing or clearing them
You can view and clear cookies and local storage in your browser settings. If you clear them, the platform will treat you as a new visitor and you may be shown questions you have already answered. Your earlier votes still count.
