Cookie
policy.

The short version

We only use cookies that are strictly necessary by default. Analytics and advertising cookies only fire after you've tapped Accept on the consent banner that appears on your first visit. You can change your preferences at any time by clicking the small Cookie preferences link in the footer.

Strictly necessary

These cookies are essential for the site to function — they keep your cart populated and remember your consent choice.

• cosykiller_cookie_consent — your cookie-consent preferences. First-party. Expires after 6 months.
• cosykiller-cart — what's in your satchel. First-party localStorage (strictly speaking, not a cookie). Cleared when you empty your cart.
• cosykiller-cart-id — a random reference for the basket itself, so that clicking through to payment more than once isn't mistaken for several different baskets. First-party localStorage. Cleared with your cart.
• ck_destination — the delivery country and postcode you last used, so you don't retype them. First-party localStorage.

Analytics (only with consent)

• _ga, _gid, _ga_* — Google Analytics 4. Measures how the site is used so we can improve it. Expires after up to 2 years.

Marketing (only with consent)

• _fbp, fr — Meta Pixel. Attribution and retargeting for Facebook/Instagram ads. Expires after up to 90 days.
• _gcl_au, _gac_* — Google Ads conversion tracking and attribution. Expires after up to 90 days.
• ck_ac_id — the email address you gave us at checkout, but only if you asked for marketing email. It lets ActiveCampaign attach your visits to your customer record. First-party. Expires after 90 days, or as soon as you withdraw marketing consent.
• prism_* — ActiveCampaign. Records which pages you visit. Only set once you've accepted marketing cookies and asked for marketing email — if either is missing, nothing is loaded at all. Expires after up to 30 days.
• ac_enable_tracking — ActiveCampaign. Remembers that you allowed page tracking. Expires after up to 1 year.

We've listed these from our own testing. If you spot one we've missed, tell us and we'll correct this page.

Changing your mind

Click Cookie preferences in the footer at any time. If you clear your browser cookies, the banner will reappear on your next visit.

Withdrawing marketing consent stops page tracking straight away and deletes the cookies we set on cosykiller.com. ActiveCampaign may also have set one on its own domain, which we can't delete from here — it expires by itself within 30 days, and your browser's cookie settings will remove it sooner.
