What we collect
- Email address, if you use the "notify me" form. Used only to email you about new tools or council coverage - nothing else, and we don't share it with anyone.
- Account email and password, if you create an account. Handled by our authentication provider, Supabase; we never see or store your password in plain text.
- Saved project details (postcode, project type, property type, dimensions, the resulting verdict and cost estimate), only if you're signed in and choose to save a project.
- Postcode, when you use the checker, to look up your local authority and check conservation area / Article 4 status via postcodes.io and planning.data.gov.uk. This isn't stored unless you save the project while signed in.
- Anonymous performance data (page load and responsiveness metrics), used only to spot slow pages - not tied to your identity.
- Anonymous usage counts - each time the checker produces a result, we log the project type, property type, region, verdict and local authority name, with no postcode, IP or other way to trace it back to you. Used only to see how the checker gets used overall.
- A hashed version of your IP address, held briefly to prevent abuse of the checker and email form (e.g. spam submissions). It's hashed before storage and isn't used for anything else.
What we don't do
No advertising, no third-party analytics or tracking cookies, and we don't sell or share your data with anyone else. The only cookie this site sets is the sign-in session cookie, and only if you're signed in.
Where your data is processed
Data is stored with our database and authentication provider, Supabase. We don't use it for anything beyond running the features described above.
Your rights
Under UK GDPR, you can ask to see, correct, or delete the data we hold about you at any time. Email contact@planthenbuild.co.uk and we'll action it directly - there's no self-service deletion yet, so this is handled by hand for now.
