Cookie Policy

How we use cookies

We only use cookies when they improve the planning tools. Learn what is currently active and how to adjust your preferences.

Essential cookies

These keep the site secure and remember lightweight settings such as preferred measurement units. They are required for the calculators to function.

Analytics cookies

Only Google Analytics 4 runs today, and we anonymise IP addresses. Plausible support exists in code but is disabled. If we ever add additional cookies, an opt-in banner will appear.

Third-party embeds

Interactive maps and external videos may set their own cookies. We only embed trusted partners and will flag any additional policies users should review.

Review or change your settings via the forthcoming preference center—updates will be announced on the blog.
