Privacy

Simple version: we collect what we need, we don't sell it, and you can delete it any time.

What we collect

  • Your postcode and address (used to model your roof; not shared)
  • Your assessment answers (about your home, electricity use, motivations)
  • Your email address — only if you provide it (for Solar Shadow updates or feedback)
  • Aerial imagery of your home (Google's satellite layer, cached for 6 months to save on API costs)
  • Technical data (browser, device — standard web analytics)

How we use it

  • To produce your personalised solar and battery assessment
  • To power the Solar Shadow weekly simulation (if you opt in)
  • To email your assessment to you (if you ask)
  • To improve the tool based on aggregate patterns
  • To notify you about new features (only if you opt in)

What we don't do

  • We never sell your personal data
  • We never pass your details to installers without your explicit consent
  • We never use your data for advertising
  • We never contact you unless you've asked us to

Anonymised insights

We may use anonymised, aggregated data to publish patterns (e.g. "62% of detached homes assessed in Bristol are strong fits for solar"). No individual is ever identifiable in these.

Where your data lives

  • Supabase, hosted in the EU
  • Anthropic Claude API processes your data when generating narratives and answering coach questions. Anthropic does not retain it.

Your rights

  • You can request a copy of all data we hold about you
  • You can request deletion of all your data
  • You can withdraw any consent at any time
