Cookie Policy

Last updated October 2026

This policy lists every cookie https://ideal-postcodes.co.uk and its subdomains can set, who sets it and why. It also names each company that receives data through those cookies.

You choose which cookies we use from the banner shown on your first visit. Change your choice at any time from the Cookie settings link at the foot of every page.

Categories

Category Needs your permission What it covers
Necessary No Running the site, keeping it secure, remembering your cookie choice, chat
Analytics Yes Understanding how the site is used, including session recordings, and which campaign or site brought you here
Marketing Yes Measuring our adverts

Without your permission we only count visits, without cookies or any other storage on your device. PostHog does this by combining your IP address, browser and a random value that changes daily into a one-way code. The code cannot be reversed, and the daily value is deleted once that day is counted.

If your browser sends a Global Privacy Control signal, "Accept all" leaves Marketing off. You can still switch Marketing on yourself under Manage cookies.
