Terms of Service

Last updated: 11 August 2026

1. Who these terms are between

These terms govern the use of the Datacompany attribution and marketing-mix-modelling service (the “Service”), provided by Datacompany, registered in the Netherlands under KVK number 64705439, at Bovendiepen 9, 9471 JE Zuidlaren (“we”, “us”).

“Customer” means the company that subscribes to the Service. “User” means a person the Customer authorises to use the Service. “Customer Data” means all data we retrieve from the Customer’s connected sources, together with anything the Customer uploads or enters.

The Service is offered to businesses only. By creating an account or using the Service you confirm you are authorised to accept these terms on behalf of the Customer.

2. What the Service does

We connect to the marketing, analytics and CRM sources the Customer authorises, combine that data, and produce attribution results, marketing-mix model estimates, dashboards, reports and answers to questions about the Customer’s marketing performance.

Results are statistical estimates, not measurements. A marketing-mix model infers the likely contribution of each channel from historical data. Estimates carry uncertainty, change as new data arrives, and depend on the quality and completeness of what the Customer connects. The Service supports commercial decisions; it does not make them, and we do not guarantee any particular return on advertising spend or business outcome.

3. Accounts and security

The Customer is responsible for who it invites, and for what those Users do in the Service.
Credentials are personal and must not be shared. Tell us promptly if you suspect an account has been compromised.
We may suspend an account immediately where we reasonably believe it is being used unlawfully, is compromised, or threatens the security or availability of the Service for others.

4. Connecting data sources

We only access what the Customer connects. Each connection is created by an authorised User, either through the provider’s own OAuth consent screen or by supplying read-only credentials.
The Customer warrants that it is entitled to grant us access to each connected source and to have us process the data in it, including where that data was collected from the Customer’s own website visitors, leads or customers, and that it has provided any notices and obtained any consents required for that.
The Customer can disconnect any source at any time. Disconnecting stops all future syncing immediately.
Some connections are made through Windsor.ai as an intermediary. Where that is the case, it is shown in the connection screen before the connection is created.

5. Third-party platforms

Google, Meta, LinkedIn, Microsoft, HubSpot, Piwik, Windsor.ai and any other connected provider are independent third parties. We are not affiliated with them and we do not control them. Use of their platforms remains subject to their own terms with the Customer. If a provider changes, restricts or withdraws its API, or revokes our access, the affected part of the Service may stop working; we will make reasonable efforts to restore or replace it but cannot guarantee continuity of any specific integration.

6. Ownership of data, results and software

The Customer owns its Customer Data. The Customer grants us a limited, non-exclusive licence to host, process and analyse it for the sole purpose of providing the Service to that Customer, and to keep backups.
The Customer owns the results we produce for it and may use them freely inside its own business.
We own the Service — the software, model implementations, methodology and documentation, including any improvements we make. Nothing in these terms transfers that to the Customer.
No cross-customer use. We do not use one Customer’s data to produce another Customer’s results, and we do not sell or share Customer Data. We may use aggregated, anonymised statistics that cannot identify the Customer or any individual to operate and improve the Service. Data received from Google APIs is additionally subject to the Limited Use commitments in our Privacy Policy.

7. Acceptable use

The Customer and its Users must not:

connect data they are not entitled to share with us;
attempt to access another customer’s data, or probe, scan or interfere with the Service or its infrastructure;
reverse engineer, copy or resell the Service, or use it to build a competing product;
use the Service unlawfully, or to process special categories of personal data or data about children;
place unreasonable load on the Service, including through automated scraping of its interface.

8. Privacy and data protection

Our handling of personal data is described in our Privacy Policy. Where we process personal data contained in Customer Data, the Customer is the controller and we are the processor. A data processing agreement on those terms is available on request from jeroen@datacompany.nl and, once signed, forms part of the agreement between us.

9. Fees and payment

Fees, the billing period and any trial or pilot arrangement are those set out in the written quotation, order form or pilot agreement agreed with the Customer. Unless stated otherwise there: prices are in euros and exclude VAT, invoices are payable within 14 days, and fees may be revised once per year with at least 30 days’ written notice. Where a free pilot has been agreed, it runs for the agreed period and creates no obligation for either side to continue afterwards.

10. Availability and support

We aim to keep the Service available during business hours and beyond, but we do not commit to a specific uptime percentage or response time unless a separate service level agreement has been signed. We may take the Service down for maintenance, and will try to do so outside Dutch business hours for anything we expect to be disruptive. Support is provided by email at jeroen@datacompany.nl.

11. Warranties and disclaimer

We warrant that we will provide the Service with reasonable skill and care. Beyond that, and to the extent permitted by law, the Service is provided “as is”: we do not warrant that it will be uninterrupted or error-free, that every integration will keep working, or that its estimates will be accurate or fit for any particular decision the Customer takes.

12. Liability

Neither party excludes liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot lawfully be excluded.

Subject to that, we are not liable for indirect or consequential loss, lost profits, lost revenue, lost or wasted advertising spend, loss of goodwill, or decisions taken on the basis of the Service’s output. Our total liability under or in connection with the agreement is limited to the total fees paid by the Customer in the twelve months preceding the event giving rise to the claim.

13. Confidentiality

Each party will keep the other’s non-public information confidential, use it only to perform the agreement, and protect it with at least the care it applies to its own confidential information. This does not apply to information that is public through no fault of the receiving party, was already lawfully known to it, or must be disclosed by law.

14. Term, termination and what happens after

The agreement runs for the term stated in the applicable order form, and renews for successive equal periods unless either party gives notice before the end of the current period.
Either party may terminate immediately if the other materially breaches these terms and fails to fix it within 30 days of being told, or becomes insolvent.
On termination, access to the Service ends. On request during the 30 days that follow, we will provide an export of the Customer’s data and results. After that period we delete Customer Data as described in the Privacy Policy.
Fees already invoiced for the current period remain payable.

15. Changes to the Service and to these terms

We continue to develop the Service and may change or remove features. We will not materially reduce core functionality during a paid term without offering the Customer a way out. We may update these terms; for material changes we will give at least 30 days’ notice by email or in the application. Continuing to use the Service after that period means the updated terms apply.

16. Other terms

Subcontractors. We may use the sub-processors listed in the Privacy Policy and remain responsible for their performance.
Assignment. Neither party may assign the agreement without the other’s consent, except to a successor of its business.
Force majeure. Neither party is liable for failure caused by events beyond its reasonable control, including outages at a third-party platform or hosting provider.
No waiver. Not enforcing a right does not waive it.
Severability. If a clause is unenforceable, the rest stays in force.
Entire agreement. The order form, these terms, the data processing agreement and the Privacy Policy form the whole agreement. If they conflict, the order form prevails, then the data processing agreement, then these terms.
Publicity. We will not name the Customer as a reference or use its logo without written permission.

17. Governing law and jurisdiction

These terms are governed by the law of the Netherlands. Disputes will be submitted to the competent court of Rechtbank Noord-Nederland, location Assen. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

These terms are written in English. A translation may be provided for convenience; in case of conflict the English version prevails.
