These Terms of Use ("Terms" or "Agreement") govern your access to and use of the Causality Engine application ("Application") operated by Causality Engine B.V., a company registered in Utrecht, the Netherlands ("Causality Engine," "CE," "we," "us," or "our").

1.1. Through our Application we offer paid services. The paid services ("Services") consist of a marketing attribution and analytics platform that helps you understand and optimize your marketing performance. Our Services include data integration, attribution modeling, journey mapping, and reporting tools. We connect with various advertising platforms and marketing tools to collect performance data. This data is then processed by an ensemble of commercially available artificial intelligence models to provide users with clear and actionable insights. The Application does not train proprietary machine learning models on your data; it orchestrates third-party AI services to generate analyses. The current list of sub-processors is maintained in our Privacy Policy.

1.2. The Application is intended exclusively for internal business use. It is not permitted to use the Application for the benefit of third parties or third-party events.

AI Calling Agent — Terms & Disclosure Statement

Last updated: 7 July 2026

This Terms & Disclosure Statement ("Statement") governs outbound telephone calls, text messages, and emails made by the Causality Engine AI calling agent (the "Agent"), and conversations held with the Agent through the web widget on our website. The Agent is operated by Causality Engine B.V., a company registered in Utrecht, the Netherlands ("Causality Engine," "CE," "we," "us," or "our"). This Statement supplements our Terms of Use and Privacy Statement, available at www.causalityengine.ai. Where you become a customer of the Causality Engine application, the Terms of Use apply to your use of that application.

1. What the Agent Is

1.1. The Agent is an artificial-intelligence voice assistant. It is not a human being. It speaks with a synthesized clone of the voice of Joris van Huët, founder of Causality Engine, created and used with his explicit consent.

1.2. The Agent identifies itself as an AI at the start of every conversation and will confirm that it is an AI whenever asked. It is configured never to deny being an AI.

1.3. The Agent's sole purpose is to make initial business contact on behalf of Causality Engine: introducing our marketing-attribution services and, where there is interest, scheduling an online demonstration with a human representative. The Agent does not conclude contracts, take payments, or make binding commitments on our behalf.

2. Why You Were Contacted

2.1. The Agent contacts businesses in a business-to-business (B2B) context only. We contact organisations that, based on publicly available business information, may benefit from marketing-attribution services.

2.2. Contact details used by the Agent are obtained from publicly published business sources, including contact information that a business has itself published on its website (such as a listed phone number or a published contact email address), and from our customer-relationship records where prior contact exists.

2.3. Our legal basis for this processing under the General Data Protection Regulation (GDPR) is legitimate interest (Article 6(1)(f) GDPR): direct marketing of relevant business services to businesses. We balance this interest against your rights, and we honour objections immediately (see Section 7).

2.4. We aim our outreach exclusively at businesses. If we have contacted you in error in a private capacity, tell the Agent or email us and we will remove your details from our outreach records.

3. Call Recording, Transcription and AI Processing

3.1. Calls with the Agent are transcribed and may be recorded for quality assurance, appointment administration, and improving our outreach. The conversation is processed in real time by third-party AI services to generate the Agent's responses.

3.2. Third-party service providers involved in a call may include: telephony carriers (call transport), conversational-AI and speech providers (speech recognition, voice synthesis, dialogue), scheduling services (appointment booking), our CRM provider (contact records), and email providers (follow-up correspondence). Each provider processes data under its own terms and our data-processing arrangements. A current list of sub-processors is maintained in our Privacy Statement.

3.3. No AI provider used by the Agent trains its models on the content of your conversation as part of our configuration; conversation data is used for real-time inference and for our own records.

4. Text Messages (SMS)

4.1. The Agent may send a short SMS announcement from the same telephone number shortly before calling, so that you can recognise the incoming call. Such messages are identification notices, not advertising, and are sent only to business mobile numbers we intend to call.

5. Emails

5.1. The Agent's outreach may be preceded or followed by short business emails. Every such email contains a working one-click unsubscribe link and our contact details. Unsubscribing stops all marketing email from us to that address immediately.

6. Contact Frequency and Calling Hours

The Agent operates within hard, technically enforced limits:

Calls are placed only on working days (Monday–Friday), between 09:00 and 17:00 (Amsterdam time), and never on Dutch public holidays.
A maximum of 7 call attempts are ever made to one contact, with at least 3 business days between attempts.
If you indicate you are not interested, we apply a pause of at least 90 days before any renewed contact, if any.
If you ask not to be called again, that request is permanent and takes effect immediately (see Section 7).

7. Your Rights and Opting Out

7.1. Do not call. Tell the Agent "bel me niet meer" (or words to that effect) at any time during a call, or email us. Your number is placed on our internal do-not-call list immediately and permanently; the Agent is technically prevented from dialling numbers on that list.

7.2. Email opt-out. Use the unsubscribe link in any email, or email us. Suppression is immediate.

7.3. GDPR rights. You have the right of access, rectification, erasure, restriction of processing, data portability, and the right to object to processing based on legitimate interest, including direct marketing. Objections to direct marketing are always honoured without requiring justification. To exercise any right, contact legal@causalityengine.ai. We respond within the statutory time limits.

7.4. Complaints. You may lodge a complaint with the Dutch Data Protection Authority (Autoriteit Persoonsgegevens) if you believe our processing infringes the GDPR.

8. Data Collected During Conversations

8.1. During a call the Agent may note business-relevant information you volunteer, such as: your role, the marketing channels your business uses, tooling in use, and — if you choose to book a demonstration — your name and business email address for the calendar invitation.

8.2. This information is stored in our CRM against your business's record and used solely to prepare and conduct the demonstration and to manage our business relationship. It is not sold or shared for third-party marketing.

8.3. Retention: conversation records and derived notes are retained for as long as reasonably necessary for the outreach relationship and then deleted or anonymised. You may request earlier deletion at any time (Section 7.3).

9. Appointments

9.1. Appointments proposed by the Agent are conducted online (Google Meet) with a human representative of Causality Engine. The Agent will confirm the date, time, and email address with you during the call, and you will receive a calendar invitation by email. You can cancel or reschedule at no cost via the link in the invitation or by emailing us.

9.2. Booking a demonstration creates no payment obligation. Any subsequent purchase of our services is governed by our Terms of Use and the pricing stated there.

10. Web Widget

10.1. Where we offer the Agent as a voice widget on our website, these same disclosure and processing terms apply to those conversations. By starting a widget conversation and granting microphone access, you consent to the audio processing described in Section 3 for the duration of that conversation.

11. Accuracy and No Advice

11.1. The Agent generates responses with artificial intelligence and, despite our safeguards, may occasionally be inaccurate or incomplete. Statements made by the Agent are informational and do not constitute an offer, advice, or a binding representation. Product commitments are made only in writing by Causality Engine or in our Terms of Use.

12. Liability

12.1. Section 10 (Liability) of our Terms of Use applies to this Statement by reference. To the maximum extent permitted by applicable law, Causality Engine's total aggregate liability arising from or related to the Agent's outreach towards a party that is not a customer shall be limited to EUR 500. Nothing in this Statement excludes or limits liability that cannot be excluded or limited under mandatory Dutch law.

13. Changes to This Statement

13.1. We may amend this Statement from time to time. The current version is always available at www.causalityengine.ai. Material changes will be reflected by an updated "Last updated" date at the top of this document.

14. Governing Law and Jurisdiction

14.1. This Statement and any disputes arising out of or in connection with it are governed by the laws of the Netherlands.

14.2. Any disputes that cannot be resolved amicably shall be submitted to the exclusive jurisdiction of the competent court in The Hague, the Netherlands.
