How we handle your details

House Price Derry collects the details needed to prepare and email your estimate. The first step saves postcode, house number or name, property type, estimate, timestamp, and session id. The second step adds first name, email, and consent choices.

Who is responsible for your data

House Price Derry is operated by Blue Canvas, Derry/Londonderry, Northern Ireland, which is the data controller for this site. For any privacy question, request, or complaint, email contact@bluecanvas.ai.

What we collect

• Postcode, house number or name, optional street, property type, and optional property details such as bedrooms, condition, parking, garage, and garden.
• First name and email when you ask to reveal and receive the estimate.
• Required privacy consent for sending the estimate.
• Optional estate-agent contact consent, which is off by default.
• The estimate, confidence tier, and source breakdown used to calculate it.

How we use it, and the lawful basis for each use

• Calculating your estimate and emailing it to you. Lawful basis: legitimate interest — you asked for the estimate and these steps are necessary to deliver it. The estimate is calculated from official UK House Price Index data for Derry City and Strabane.
• Keeping a record of the estimate and your consent choices. Lawful basis: legitimate interest, so we can evidence what was sent, to whom, and with what consent.
• Passing your details to a local estate agent. Lawful basis: consent. This only happens if you tick the separate optional agent-contact box. If the box is not ticked, your details are not sold or passed to anyone for agent outreach.
• Any future marketing email. Lawful basis: consent. We do not send marketing without a separate opt-in.

Who processes the data

Your details are stored and handled by these processors on our behalf:

• Supabase — database hosting for valuation leads.
• Resend — delivery of the estimate email.
• Vercel — website hosting.

How long we keep it

Completed valuation leads are kept for 12 months from the date of the request, then deleted. Partial form entries that never complete are deleted after 90 days. You can ask for earlier deletion at any time.

Estate-agent contact

We only pass your details to a local estate agent if you tick the separate optional box saying you are happy to be contacted. If that box is not ticked, your details are not sold or passed on for agent outreach.

Cookies and bot protection

The form uses a session id, honeypot field, and basic rate limiting to reduce spam. No advertising cookies are required for v1.

Your rights

You can ask for access to your data, correction, deletion, restriction of processing, or a copy of the data you gave us, and you can withdraw consent at any time. Email contact@bluecanvas.ai and we will respond within one month. If you are unhappy with how we handle your data, you have the right to complain to the Information Commissioner's Office (ICO) at ico.org.uk/make-a-complaint.
