Effective: May 2026

This site does not store your postcode. There is no campaign-controlled server that logs or processes postcode lookups. Distance calculations run locally in your browser.

What happens when you enter a postcode

The postcode lookup sends the postcode you type to postcodes.io to retrieve approximate coordinates for that postcode area. That request goes directly from your browser to postcodes.io. This site does not see, log, or store the postcode. postcodes.io is a third-party service maintained by Ideal Postcodes. This site does not control how postcodes.io handles requests. See Ideal Postcodes' privacy information for details.

The distance calculation then runs locally in your browser using the coordinate returned. This site has no campaign-controlled postcode database or server-side postcode log.

Copy and share

When you use the share button after a result, your browser copies a short link to this site to your clipboard (or hands it to your device's share sheet). The link includes your postcode in its URL (after ?pc=), so the person you share it with sees the same result you did. On phones, the share sheet may also include the full result text, which names your postcode. If you do not want to share your postcode, copy and paste only the parts of the text you want.

Map tiles

The map is rendered using OpenFreeMap. As you pan and zoom, your browser requests map tile images from OpenFreeMap's servers. Those requests include the tile coordinates your browser is loading — a standard feature of all web maps. We do not control or log those requests.

Fonts and scripts

Page fonts are loaded from Google Fonts. Page scripts and the map library are loaded from jsDelivr (a public CDN). These are standard third-party services; your browser connects to their servers as part of loading the page.

Cookies and local storage

This site sets no cookies, uses no local storage, and uses no session storage.

Analytics

This site uses Vercel Web Analytics to count page views and visitor geography (country / device). Vercel Web Analytics is privacy-respecting: it sets no cookies, does not track individual users across sites, and does not collect personal information. It does not see, log, or store your postcode. The analytics script is served from the same server as this page (/_vercel/insights/script.js). For details see Vercel's analytics privacy policy.

Geographic data

The boundary and infrastructure data files (GeoJSON) are served from the same server as this page. No information about you is embedded in or returned from those files.
