Terms of Service

Last updated: September 1, 2026

These terms govern the use of the Historian platform and this website, both operated by Historian ApS. By creating an account or using the Platform, you accept these terms on behalf of the business you represent. Please read them together with our Privacy Policy, which explains how we handle data, and our Data deletion page, which explains how to have data deleted.

1. Definitions

  • Historian, we, us — Historian ApS, the Danish company that provides the Service.
  • Website — http://historian.ai, accessible from https://historian.ai.
  • Platform — the Historian application made available to Customers at https://app.historian.ai, including the analyses, reports and AI-generated insights provided through it.
  • Service — the Website and the Platform, taken together.
  • Customer, you — the business that has entered into an agreement with Historian for the use of the Platform.
  • Customer Data — the data we process on your behalf and on your instructions in order to provide the Platform. It includes data collected from visitors to your own website and Advertising Data.
  • Advertising Data — the data we retrieve, on your behalf and with your authorisation, from the advertising platforms you connect to the Platform (Google Ads, Meta). Advertising Data is a subset of Customer Data.

2. The Service

Historian is an analytics service for e-commerce businesses. You install our recording script on your website, and the Platform analyses how visitors use it and reports what it finds — including insights produced by AI agents that work on your data.

Advertising integrations are optional. You can connect the advertising accounts you use (Google Ads, Meta) to the Platform so that your advertising can be related to what happens on your website. A connection is only made when a person authorised on your side explicitly grants Historian access through the advertising platform's own authorisation flow. We do not have access to any advertising account you have not connected, and you can disconnect at any time (see section 4).

The commercial terms of your subscription — the plan, the price, the billing period and any optional add-ons — are set out in your customer agreement or order with Historian. Where these terms and your customer agreement differ, the customer agreement applies.

3. Your account

An account may only be created by a person who is authorised to act on behalf of a business. The Platform is for businesses; it is not intended for consumers.

You are responsible for the people you give access to your account, for what they do in the Platform, and for keeping login credentials confidential. Tell us at contact@historian.ai if you believe an account has been used without authorisation, and we will help you secure it.

You must ensure that the information you give us about your business is correct and kept up to date.

4. Third-party platforms

When you connect an advertising account, you also accept the terms of the platform that provides it — for example the Google Ads and Google API terms, or the Meta Platform Terms — and you confirm that you are entitled to grant access to that account. Those platforms are not part of the Service and we are not responsible for their availability, their terms or the accuracy of the data they provide.

We read only what you have authorised. The scope of a connection is determined by the permissions you grant in the platform's authorisation flow, and we use the data solely to provide the Platform to you.

You can end a connection at any time from within the Platform — for Google Ads, open Integrations → Google Ads and click Disconnect — or by revoking Historian's access in your own account with the platform. Disconnecting stops further collection immediately; what it does and does not delete is described on our Data deletion page.

5. Data and privacy

How we process data, in what roles, for how long, and how it is deleted is set out in our Privacy Policy. In short: for Customer Data, including Advertising Data, we act as data processor and you are the data controller; for visitors to the Website itself, we are the data controller. The data processing agreement that forms part of your customer agreement governs our processing on your behalf.

You are responsible for having a lawful basis for the data you collect through the Platform, including any consent your visitors are required to give, and for the information you owe your visitors about your use of Historian.

Instructions for having data deleted are on our Data deletion page.

6. Acceptable use

You agree not to:

  • resell, sublicense or make the Service or Customer Data obtained through it available to third parties, other than as part of your own business's ordinary use of its own data;
  • use the Service to collect data you are not entitled to collect, or from websites you do not operate or have authority over;
  • interfere with, circumvent or attempt to gain unauthorised access to the Service, its security measures, or the systems of other Customers;
  • use the Service in a way that violates applicable law or the terms of a connected advertising platform.

We may suspend access if we reasonably believe the Service is being used in breach of these terms. We will tell you why and, where the problem can be fixed, give you the opportunity to fix it.

7. Intellectual property

Your data is yours. You retain all rights to Customer Data. You give us the right to process it only to the extent needed to provide the Service to you and as described in the Privacy Policy.

Our software is ours. The Platform, the Website, the recording script and all software, designs and documentation that make up the Service belong to Historian or its licensors. Your subscription gives you a non-exclusive, non-transferable right to use the Service for your own business while your agreement is in force. It does not transfer any ownership.

The analyses, reports and insights the Platform produces from your data are yours to use for your business. We may use aggregated, anonymised information about how the Service is used in order to improve it; such information does not identify you or your visitors.

8. Availability and changes to the Service

We aim to keep the Service available and to give notice of planned maintenance. We may improve, change or discontinue features of the Service. Where a change materially reduces what your subscription includes, we will tell you in advance.

9. Liability

The Service is provided to help you understand your website and your advertising. The insights it produces are based on the data available to it and are meant to inform your decisions, not to make them; you remain responsible for the decisions you take.

To the extent permitted by Danish law, Historian is not liable for indirect or consequential loss, including loss of profit, revenue, data or business, and our total liability under these terms in any twelve-month period is limited to the amount you have paid us for the Service in that period. Nothing in these terms limits liability that cannot be limited under applicable law.

10. Term and termination

Your subscription runs for the period stated in your customer agreement. Either party may terminate in accordance with that agreement, and we may terminate for material breach of these terms if the breach is not remedied after notice.

When your agreement ends, your access to the Platform stops. What happens to your data afterwards — what we keep, for how long, and how it is deleted — is set out on our Data deletion page and in the Privacy Policy; we do not restate it here so that there is one place for it.

11. Changes to these terms

We may update these terms. When we do, we will publish the new version on this page with a new "Last updated" date and, for changes that affect you materially, notify you by email to your account's contact address before the changes take effect. Continued use of the Service after that date means you accept the updated terms. If you do not, you may terminate in accordance with your customer agreement.

12. Governing law and venue

These terms are governed by Danish law. Any dispute that cannot be resolved by agreement shall be brought before the Danish courts, with the City Court of Copenhagen as the court of first instance.
