Essential cookies
These are required for the site to function. They store no personal information beyond what’s needed to remember your session and cookie preferences.
- rcc:cookie-consent — remembers your cookie choice so we don’t ask again on every page.
- Authentication cookies — set when you sign in to the admin area.
Analytics cookies (optional)
Only set if you click “Accept all” on the cookie banner. These help us understand which pages people find useful so we can improve the calculator. They do not identify you personally.
Advertising cookies
We display advertising served by Google AdSense to keep the calculator and city guides free. Google and its partners may set cookies (including the DoubleClick DART cookie) to serve and measure ads based on your visits to this and other websites. In the UK and EEA we only enable personalised advertising cookies if you select “Accept all” on the cookie banner; otherwise non-personalised ads are shown. You can manage or opt out at any time via Google Ads Settings or read Google’s advertising policies. See our privacy policy for full details.
