Privacy policy

Last updated: 24 July 2026

Level Best is a planning tool for house and garden projects, operated by Richard Cowtan trading as Level Best, in the United Kingdom. This page says what data we hold, why, and what your rights are. The short version: we hold what the tool needs to work, we don't sell it, we don't run adverts, and you can export or delete everything.

What we collect

Signing in uses your browser's local storage strictly to keep you signed in. If we ever advertise, the ad networks' cookies (Reddit or Meta) load only if you accept them when asked: decline and the site works exactly the same, minus their measurement.

Why we hold it (lawful bases)

Who processes it for us

We don't sell or share your data for marketing. It passes through these services, each doing one job:

ServiceJobWhat they see
Supabase (EU region)Database, sign-in, file storageAccount and project data, at rest in the EU
VercelHosting the site and appStandard web-server request data
AnthropicThe AI assistantThe project context needed to answer: sent when you use an AI feature, not otherwise
Google (Places)Finding local tradesThe search query, including your project's area, when you use the trade finder
ResendSending and receiving our emailYour email address, and the contents of any message you send us or we send you
GoatCounterAnonymous visit countsNo personal data

If paid plans launch, payments will be handled by Stripe; card details would go to Stripe directly and never touch our systems.

How long we keep it

While your account exists. Delete a project and it's gone from your account immediately; delete your account and everything goes with it. Residual copies in short-term backups cycle out within 30 days.

Your rights

Under UK GDPR you can ask to see, correct, export, or delete your data. The useful ones are built in: full export (open formats, any time, in the app) and project deletion. For account deletion or anything else, email hello@levelbest.build: done within 30 days, usually much faster. If you're unhappy with how we've handled your data, you can complain to the ICO (ico.org.uk).

Security

Data is encrypted in transit and at rest, stored in the EU, and protected by per-user access rules enforced in the database itself: your projects are readable by your account and nobody else's. Sign-in is by emailed one-time link; there are no passwords to leak.

Age

Level Best is for adults planning real projects; it isn't directed at children and we don't knowingly hold data on anyone under 16.

Changes

If this policy changes in any way that matters, we'll say so plainly on the site, not bury it.
