Reading, filtering and calculators
The site’s search filters and calculators operate in your browser. Their code does not save your entries in cookies, local storage or session storage, and does not send those entries to an application server.
In a clean-browser check on 18 October 2026, the public home, privacy, support, licence-search and calculator pages set no cookies and created no local storage, session storage, IndexedDB databases or browser caches. No third-party analytics or advertising requests were observed, including after calculator and search inputs. This describes that check, not every possible hosting security response.
Browser features such as form history may remember values independently of this site. Close the page or clear your browser’s form data if you use a shared device.
Hosting and security
Cloudflare delivers the site and processes web requests. Its security features can behave differently from the site’s own tools, including when a browser check is required. Provider cookies, if used, are governed by the relevant Cloudflare documentation.
The publication does not use an advertising-cookie preference to enable its calculators or filters. We have not added advertising pixels or affiliate conversion tracking.
Links and your browser settings
Opening an external source creates a request to another website. That website may set its own cookies or ask for consent under its own policies.
You can review and remove site data in your browser settings. Blocking cookies does not prevent a web request from reaching the hosting provider.
If these practices change
This page should reflect the technology actually used by the publication. Changes that introduce new tracking or storage need an updated explanation and any applicable choice before use.
