Cookie Policy

Last updated: May 2026

What are cookies?

Cookies are small text files placed on your device when you visit a website. They are widely used to make websites work efficiently and to provide information to the site owner. Under UK law, cookies that are not strictly necessary require your consent before being set.

Cookies we use

Essential

Authentication (Supabase)

When you log in, Supabase sets a session cookie to keep you signed in as you navigate between pages. Without this cookie the site cannot function for logged-in users.

CookiePurposeDuration
sb-*-auth-tokenKeeps you logged inSession / 1 week

Consent required: No — these are strictly necessary.

Analytics

First-party analytics (999ready)

To understand how visitors use the site — for example which pages are viewed and how long people spend on them — we store a couple of first-party identifiers in your browser's local storage (not third-party cookies). These stay on your device and are only sent to our own servers. We only set them once you have given consent.

NamePurposeDuration
r999_visitor_idAnonymous visitor ID (local storage)Persistent
r999_first_touchRemembers how you first arrived (referrer / source, local storage)Persistent

Consent required: Yes — non-essential analytics.

Advertising

Referral attribution

If you arrive via a referral link (a ?ref= link), we store the referral code in a first-party cookie so that, if you go on to buy, the purchase can be attributed to the person who referred you.

CookiePurposeDuration
ref_codeReferral attribution45 days

Consent required: Yes — non-essential.

Advertising

Google Ads

We use Google Ads to run search campaigns. Google sets a cookie to measure whether someone clicked one of our ads before visiting the site, so we can understand which campaigns are working. Data may be stored in the United States.

CookiePurposeDuration
_gcl_auAd conversion tracking90 days

Consent required: Yes — non-essential advertising cookie.

Essential

Vercel Analytics

Our hosting provider Vercel collects aggregated, anonymous page-view data to help us monitor site performance. Vercel Analytics does not set any cookies and does not collect personal data or IP addresses.

Consent required: No — no cookies set, no personal data collected.

How to manage cookies

You have several options to control non-essential cookies:

  • Browser settings — all modern browsers let you block or delete cookies. Visit your browser's help section for instructions (Chrome, Firefox, Safari, Edge).
  • Google opt-out — install the Google Analytics Opt-out Browser Add-on to prevent Google Analytics from tracking your visits.
  • Ad personalisation — manage your Google ad settings at adssettings.google.com.

Blocking essential cookies (Supabase) will prevent login from working. Blocking analytics and advertising cookies will not affect your ability to use the tests.
