Privacy policy

Plain English about what SiteSums holds, why, for how long, and what you can do about it. Written for the people who use the platform — and for their clients, whose details end up in it.

Last updated 16 September 2026 · SiteSums is operated by Nikita-Jade Hancock, 124 City Road, London EC1V 2NX. Questions: privacy@sitesums.co.uk

Who we are

SiteSums is a business admin platform for UK trades, operated by Nikita-Jade Hancock. For your own account details we are the data controller. For the details of your clients that you store in SiteSums, you are the controller and we are your processor — the data processing terms set out how that works. We are registered with the Information Commissioner's Office under number ZC244828.

Our lawful basis

  • Contract — almost everything above is needed to provide the service you signed up for: producing documents, taking payments, keeping your records.
  • Legitimate interests — technical logs and security measures that keep the service working and your data safe. We have weighed these against your interests and kept what we hold to the minimum.
  • Legal obligation — where the law requires us to keep records, for example of payments processed.
  • We do not rely on consent for any of the above, and we do not use your data for marketing unless you ask us to.

Your clients' details

When you add a client to SiteSums and send them a quote, you are the controller of their information. We store it on your instructions, show it only to you and to them (through the links you send), and delete it when you do. We never contact your clients ourselves, sell their details, or use them for anything except your documents. You are responsible for having a lawful basis to hold their details — for almost every trade, that is simply the contract or enquiry between you.

Who else sees data

We use a small number of specialist providers. None of them may use the data for their own purposes.

ProviderDoesWhereTransfer safeguard
SupabaseDatabase, sign-in and file storageLondon, UK (eu-west-2)None — data at rest stays in the UK
Vercel Inc.Application hostingUSA (global edge network)UK Addendum to the EU Standard Contractual Clauses, via Vercel's DPA

Your data at rest lives in the UK. Where a provider is outside the UK, the transfer is covered by the UK Addendum to the EU Standard Contractual Clauses in that provider's data processing agreement. We do not sell data, and we share it only as listed here or where the law requires.

Card payments

Card details go directly to Stripe and never touch SiteSums' servers. We hold a Stripe customer reference and your subscription status, nothing more. Your own bank details — which you enter so clients can pay you by transfer — are stored encrypted and appear only on the documents you produce.

Security

Every account is isolated at the database level: the rules that decide who may read a row are enforced by the database itself, not just by the application. Data is encrypted in transit and at rest. Receipts and template files are in private storage; logos and project cover images are public web addresses because they appear on pages your clients open. The security page has the detail.

Your rights

  • Access and portability — Settings → Export gives you everything we hold about your account as a file, instantly.
  • Erasure — Settings → Delete account removes your account and everything in it, including files. It is immediate and cannot be undone; backups age out within 30 days.
  • Rectification — everything is editable in the app.
  • Objection and restriction — email us and we will act within one month.
  • You can complain to the ICO at ico.org.uk. We'd rather hear from you first: privacy@sitesums.co.uk.
