Terms of Service

Datuma does not sell you contacts. We test the contact data you already hold, and we do the work for you: you send us the file, we run the check on our own systems, and we hand the results back. Customers are not given an account and are not asked to operate anything. These terms govern that free check. Sections 8 and 9 apply to any paid full check we run for you.

This policy was last updated on 8 October 2026. It does not constitute legal advice.

1. What you are agreeing to

  • The free check. We run a check on a file of your own contacts, free of charge, once per organisation. You send us the file, we run it on our systems, and we walk you through what came back on a short call. Before any file is processed, you tell us in writing what you are asking us to do with it, and we keep that instruction as the record.

2. Eligibility

  • Datuma works only with organisations, for their business. We do not work for consumers. By sending us a file you confirm that you are acting for an organisation in the course of its business, and not as a consumer.
  • The free check is for organisations, so we ask for a work email address. We may decline a free check requested from a free email address (for example @gmail.com, @outlook.com, @yahoo.com).
  • One free check is offered per organisation.
  • You must have the authority to share the contact data you send us and to instruct us to process it.

3. How your data is handled

  • Datuma acts as your processor, on your instructions, in the European Union (Ireland). The limited cases where data leaves the UK and EU are set out in section 5 of our Data Processing Terms. See the Security page for the technical controls.
  • Your contacts are never used for our own marketing or outreach, never sold, and never used to train models. Results of third-party lookups are kept in a lookup record outside your account, described in Annex 2 of our Data Processing Terms.
  • Where we run a free check, we create a working account to run it in. You are not given access to it. That account and everything in it, including the file you sent, the records derived from it and the results, is erased 7 days after the last thing happens in it: 7 days after we run the check, or 7 days after the file arrives if we never run it. The erase is automatic and irreversible, and it happens whether or not you ask for it.
  • You can ask us to erase your data at any time.
  • We use a small number of vetted sub-processors to run the checks and the service (enrichment, email verification, hosting, and communication). The current list is published at /subprocessors. Changes are notified to customers at least 30 days in advance.
  • For the full factual description of data handling, see the Privacy Policy.

4. What we test, and what we do not promise

Datuma checks the contact data you send us against live sources at the time the check runs: duplicate and conflicting records, whether business email addresses are deliverable, whether telephone numbers are live mobile numbers, and whether people are still in the role and organisation your file says they are.

A number we mark live is reachable on the day we checked it. Whether you may call or text it for marketing depends on the rules that apply to you, including screening against the Telephone Preference Service and the Corporate Telephone Preference Service.

Results depend on third-party sources and the quality of the data you send us. We do not guarantee that every contact will return a match or any specific field. A check shows what Datuma produces on your data. It is not a commitment of outcome, and it is not legal, compliance, or investment advice.

5. Your data stays yours

Datuma retains no rights over the contact data you send us. We do not sell, share, or use your contact data to train models, and we do not merge it with any external database. We propose findings; you confirm what happens. We never overwrite or create records in your systems, and any sync to your CRM is one way out and additive only. The data you send us is processed to produce your result and is then deleted as described in section 3, in the Privacy Policy, and in full in the retention annex to our Data Processing Terms.

6. Acceptable use

The free check is for testing your own operational contact data. They are not a cleaning service for purchased or scraped cold lists. We may decline, rate-limit, or terminate any request at our discretion. You agree not to send us data that you do not have the right to process, data that is unlawful, or data intended to disrupt or misuse the service.

7. No wider client relationship

The free check does not, on its own, create a wider client relationship between you or your organisation and Datuma. No service-level commitments, support obligations, or warranties apply beyond what is stated here.

8. What happens when a full check finds little or nothing

This section applies to a full check you pay for: the check we run across the whole file you send us, handed back as the finished set of files. It does not apply to the free check in section 1, which is free of charge.

Something worth knowing means a row the full check established a fact about that your file did not carry: an address that accepts mail or does not, a number that is live or not, a profile matched to the person and read, a change of role or organisation found, a duplicate, or a row kept aside on your own list of clients and competitors. A row we could not reach, and could establish nothing about, is a row with no value. The update file, the changelog, the stopped rows and the Decision Brief carry every one of those, so the count is one you can make for yourself.

Rows with no value. For every row in your file with no value, your next full check carries two rows free. We send a credit code with the finished files. Enter it when you send your next file and each credited row comes off that full check's price at its own rate: the price divided by the number of rows that size is for. The code is valid for three months from the day we hand the full check back. It is credit, not money: it has no cash value and is not refunded.

A full check that finds nothing. If the finished full check has not found something worth knowing on at least one of the rows in your file, we refund what you paid for that full check in full. The refund takes the place of the credit code for that full check. You keep the finished files and the evidence either way.

When we decide. We make the count on the files as we hand them back, and we tell you the answer with them. If you think we have it wrong, tell us within 30 days of handback and we will work it through with you against the files.

This refund or credit is the remedy we provide under this section where a full check finds little or nothing.

This does not change section 4. We make no promise about any individual contact or about any specific field, and nothing in this section is a commitment about how long a full check takes.

9. What a full check costs, and when you pay

This section applies to a full check you pay for. It does not apply to the free check in section 1, which is free of charge.

A full check is one fixed price for the file, and it covers everything up to the number of rows its size is for. We count the rows in the file you send us, and that count decides which size applies. The prices for the published sizes are set out on the pricing page. Above the largest published size, the price is quoted from your file's row count before anything runs.

That one price covers the whole full check. There are no add-ons and no metered extras, and nothing further is charged for it.

You pay when you send your file, by Instant Bank Pay, at the price shown to you before you pay. The receipt we send when your payment is confirmed is your invoice. The walkthrough fee shown on our pricing page, where a slice of your list is taken through the full check, is credited in full, once, against the first full check your organisation orders within three months of the walkthrough. The credit has no cash value and is not transferable. If no full check is ordered in that period, the walkthrough fee is not refunded. If that full check qualifies for the refund in section 8, we refund what you paid for that full check (its price less the walkthrough credit); the walkthrough fee is not refunded.

If we cannot run the file you paid for, we refund what you paid in full.

This section is subject to section 8.

10. Limits on liability

This section applies to everything we do for you under these terms and under our Data Processing Terms, including the free check and any full check.

Nothing in these terms limits or excludes liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for anything else that the law does not allow to be limited or excluded.

Subject to that, our total liability to you for all claims arising out of or in connection with these terms, our Data Processing Terms and any check we run for you, whether in contract, in tort (including negligence), for breach of statutory duty or otherwise, is limited to the total fees you paid us in the 12 months before the claim arose.

Subject to the same exception, we are not liable for any loss of profit, revenue, business or goodwill, or for any indirect or consequential loss.

Each of us is responsible for its own compliance with data protection law. Nothing in this section limits any right an individual has against either of us under data protection law.

11. Governing law

These terms are governed by the laws of England and Wales, and the courts of England and Wales have exclusive jurisdiction over any dispute arising out of or in connection with these terms.
