Privacy policy
Last updated 31 October 2026
This policy explains what information the Quote Surveyor app collects, why, who helps us process it, and the choices you have. We have tried to keep it short and plain.
Who we are
Quote Surveyor is run by Lemonade Analysis Limited, a company registered in England and Wales with company number 14420674. Our registered office is 24 Dan y Coed Road, Cardiff, CF23 6NA. We are the controller of your personal data.
Contact us about anything in this policy at [email protected].
What we collect
| Information | Where it comes from |
|---|---|
| Your email address | You, when you sign in. We send a sign-in link to it; there is no password. |
| Quotes you upload: the file (PDF, photo, spreadsheet or pasted text) and what we read from it, such as prices, line items and terms | You. A quote may also contain your builder's details and your own name or address. |
| Project details: type of project, floor area, specification level, and whether the price includes VAT | You |
| Your postcode | You. We use it to work out your region and keep only the postcode area (for example "RG"), not the full postcode. |
| Ratings and reports we produce for you | Us |
| Purchase records: which check you bought, when, and its Google Play order reference | Google Play. We never see your card or bank details. |
| Server logs: technical records of requests and errors | Our servers. These exclude the contents of your quotes. |
How we use it, and our lawful basis
| What we do | Lawful basis (UK GDPR) |
|---|---|
| Sign you in, read your quotes, rate them, compare them and produce Full Quote Check reports | Contract: it is the service you asked for |
| Email you the free pricing-schedule template when you first sign in | Contract: it is part of the service |
| Check purchases with Google Play, unlock reports and handle refunds | Contract, and legal obligation for keeping financial records |
| Find and fix faults, prevent misuse and keep the service secure | Legitimate interests: running a reliable, safe service |
| Use your quotes to improve our checks, only if you tick the box for that quote | Consent; see the next section |
Your rating is worked out by fixed rules from published cost data. AI is used to read the quote and to word the summary, but it never decides your band, the £ boundaries or how confident we are. We do not make decisions about you that have legal or similarly significant effects.
How we improve Quote Surveyor
If you agree, we use your quotes to make our checks better
When you upload a quote you can tick "Let Quote Surveyor use this quote, with names and contact details removed, to improve future checks". The box is unticked unless you tick it, and saying no doesn't change anything else in the app.
If you tick it, we keep a copy of what we read from that quote: the prices, line items, terms and our rating. Before we store that copy, we remove:
- the builder's name, company number and contact details;
- your name;
- postcodes beyond the first part (for example "RG1");
- any bank details printed on the quote.
We don't keep a copy of the file you uploaded for this purpose.
We use these copies to:
- check how accurately we read quotes;
- test changes to our checks before we release them;
- calculate typical prices per m² for each type of project and region.
We only publish those typical prices once at least 30 quotes go into a figure, and a person on our team checks each figure first. We never train AI models on your quotes, and nothing in these copies is sold or shared.
If you answer "Did we read the total right?", we store your answer with that copy, so we can see where we misread quotes. It never changes your rating.
You can change your mind at any time: Home → "Stop using my quotes to improve checks". We stop using your quotes and delete the copies we kept. Typical prices that were already calculated from many people's quotes stay as they are, because they no longer relate to any one person.
Lawful basis: your consent (UK GDPR Article 6(1)(a)). Where a builder is a sole trader, their details on a quote are personal data too. That is one reason we remove them before keeping anything.
Your builder's details
Quotes usually name the builder. We read those details only to remove them: they are never shown in your rating, comparison or report, and never included in the copies described above.
Who helps us
We use these companies to run the service. They process data only on our instructions and under contracts that require them to protect it. We do not sell your data and the app has no advertising.
| Company | What they do | Where |
|---|---|---|
| Supabase | Database, file storage and sign-in | UK (London) |
| Railway | Runs our servers | EU (Netherlands) |
| Anthropic | AI that reads quotes and words summaries. Under our agreement it does not use your quotes to train its models. | USA |
| Resend | Sends sign-in and welcome emails | EU (Ireland) |
| Google Play payments and refunds | Google's own privacy policy applies to your Play account | |
| Cloudflare | Our website and forwarding emails sent to our support address | Global network |
Where data goes outside the UK, we rely on the safeguards UK law requires, such as UK adequacy regulations (including the UK–US data bridge) or the UK International Data Transfer Addendum to standard contractual clauses.
We may also disclose information if the law requires it, or to protect our users or the service.
How long we keep it
- Your account, quotes, project details, ratings and reports: until you delete your account.
- Copies used to improve our checks: until you withdraw consent or delete your account.
- Purchase records: six years after the purchase, because UK tax law requires us to keep financial records.
- Server logs: a short period, after which they are deleted automatically.

Quote Surveyor is for adults arranging building work. It is not intended for anyone under 18.
Changes to this policy
If we change this policy we will update the date at the top. If a change affects how we use data you have already given us, we will tell you in the app or by email first.
