Cookie policy
Last updated 11 October 2026.
The short version
Nothing non-essential loads, and no non-essential cookie is set, until you click “Accept” on the banner. “Reject non-essential” is just as easy to click. Today the only non-essential item is Microsoft Clarity analytics. Affiliate links are plain links. We do not run advertising or profiling cookies.
Change your mind at any time: . If you withdraw consent we clear Clarity’s cookies straight away and it does not load on your next page view. We ask again after 12 months.

Click logging is not a cookie
When you click a “Buy” button, our server records which product and retailer you chose, the page you came from, the time, your IP address and your browser’s user-agent text. This is a record on our server. It does not store or read anything on your device, so it does not depend on the banner. We use it to see which products people want and to filter bots, on the basis of legitimate interests, and we keep it for 12 months. The privacy policy has the detail and your rights.
Cookies set by retailers
When you click through to Amazon, eBay or a retailer on the Awin network, that company can set its own cookie on its own site so that it can credit us if you buy. We do not set or see those cookies, and they are covered by the retailer’s own cookie policy. This is how we earn commission, at no extra cost to you.
Blocking cookies in your browser
You can also block or delete cookies in your browser settings. Essential items will stop working if you do, for example the banner will ask you again. Questions? Email hello@ukaircontracker.co.uk.
