Privacy policy

Last updated 13 November 2026

DataMatched compares two databases without either side handing its file over. This policy explains what personal data we collect through datamatched.com and the DataMatched service, why, and the choices you have.

Who we are

DataMatched provides secure data matching through datamatched.com and the DataMatched service. DataMatched is a platform of Condrel Technologies LLC, which is the controller of the personal data described in this policy. Contact us at help@datamatched.com.

The most important point: your file stays with you

When you check a file with DataMatched, the file is read and matched on your own computer, in your browser. Records are locked with Private Set Intersection, using elliptic-curve cryptography (P-256), before anything is exchanged. Your file is never sent to us, and nothing from it is ever seen, sent or kept.

What we collect, why, and our lawful basis

WhatWhy we use itLawful basis
Enquiries: your name, email address and anything you write to us.To reply to you and arrange early access or a pilot.Steps you ask for before a contract; our legitimate interest in answering business enquiries.
Match results: a report number, the number of rows checked, how many people in the selection your file already holds, the selection itself, and a client name if an agency chooses to enter one.To give you your report and supply the right records if you order.Contract; legitimate interests.

Who we share it with

We do not sell personal data. We share it only with service providers who help us run DataMatched and who may use it only on our instructions:

ProviderWhat they do for us
Our UK serversThe matching service and its records are held on our own servers in the UK.
CloudflareDelivers and protects the matching service (encryption, blocking attacks).
VercelHosts the datamatched.com website.
Google FontsSupplies the typeface used on our pages. Your browser fetches it from Google, which sees your IP address.

We may also share data if the law requires it, to protect our rights, or with professional advisers.

Transfers outside the UK

Some of these providers are based in, or may process data in, the United States. Where that happens we rely on UK adequacy regulations (including the UK Extension to the EU-US Data Privacy Framework, where the provider is certified) or on the UK International Data Transfer Agreement or Addendum.
