Our legal commitments
to you.

1. Who we are

SimpleStack AI Growth Systems is a sole proprietorship registered in the Netherlands, providing AI-powered chat and voice assistant services to businesses in the EU and beyond. By purchasing or using our services, you agree to these Terms and Conditions.

2. Services

SimpleStack provides AI assistant services including but not limited to: text chat assistants, voice AI assistants, knowledge base creation, system configuration, hosting, monitoring, and monthly maintenance. The specific services delivered depend on the package selected at the time of purchase.

We reserve the right to modify or update the services offered at any time. Any material changes to an active subscription will be communicated with a minimum of 30 days notice.

3. Payment and setup fees

All packages require a one-time setup fee paid in advance before work begins. Setup fees are non-refundable once work has commenced. Monthly fees are billed from the date your AI assistant goes live.

• Core package: €149 setup + €97/month
• Growth package: €379 setup + €197/month
• Pro package: €697 setup + €297/month

Prices are quoted in euros and are exclusive of VAT where applicable. EU businesses with a valid VAT number may be eligible for 0% VAT. All prices are subject to change with 30 days notice to existing clients.

Monthly fees are fixed at the rate agreed when you subscribe. In the event of a significant increase in AI processing volume or infrastructure costs beyond standard usage thresholds, SimpleStack reserves the right to adjust monthly fees with a minimum of 30 days written notice. Clients may cancel within this notice period without penalty if they do not wish to continue at the revised rate.

4. Promotional pricing

Where promotional discounts are offered (including introductory pricing), these apply to the setup fee only unless otherwise stated in writing. Promotional pricing is available for a limited time and may be withdrawn at any time for new customers. Existing clients on promotional rates will be notified of any changes with 30 days notice.

5. Contract duration and cancellation

All service packages operate on a month-to-month basis with no minimum contract term. To cancel, you must provide 30 days written notice via email to [email protected]. Your service will remain active until the end of the notice period. No refunds are issued for partial months.

Setup fees are non-refundable under any circumstances once work has begun. If you cancel before your assistant goes live, we will refund the setup fee minus any costs already incurred for work completed.

6. Client responsibilities

You agree to:

• Provide accurate and complete content for training your AI assistant
• Respond to our requests for content and approvals within 5 business days to avoid delays
• Ensure that any content you provide does not infringe third-party intellectual property rights
• Not use the AI assistant for unlawful, harmful, or misleading purposes
• Inform us promptly of any changes to your business that may affect the accuracy of your assistant

7. Content updates

Each package includes a defined number of content updates per month (1 for Core, 2 for Growth, unlimited minor updates for Pro). A content update covers factual changes to the knowledge base such as updated prices, new services, or revised FAQs. Structural rebuilds or the addition of entirely new content categories are quoted separately.

9. Confidentiality

SimpleStack AI Growth Systems agrees to keep all information provided by the client strictly confidential. This includes but is not limited to: business information, pricing, products and services, customer data, internal documents, system credentials, and any other proprietary information shared during onboarding or in the course of the service relationship.

SimpleStack will not disclose, share, sell, or use client information for any purpose other than building, training, and operating the agreed AI assistant services. All client content is used solely on behalf of that client and is never used to train shared models or shared with other clients.

This confidentiality obligation survives termination of the service agreement and remains in force indefinitely. SimpleStack may only disclose client information where required by law, in which case we will notify the client to the extent permitted by law.

Clients who require a signed Non-Disclosure Agreement (NDA) prior to sharing sensitive information may request one by emailing [email protected]. We will provide a countersigned NDA within 2 business days.

10. Intellectual property

You retain ownership of all content you provide to SimpleStack for training purposes. SimpleStack retains ownership of the systems, tools, and methods used to build and operate AI assistants. Upon termination of services, we will provide you with a copy of your knowledge base document in a standard format upon request.

10. Limitation of liability

SimpleStack provides AI assistant services on a best-effort basis. AI systems may occasionally produce inaccurate or unexpected responses. We are not liable for any direct, indirect, incidental, or consequential damages arising from the use or inability to use our services, including but not limited to loss of revenue, loss of data, or reputational harm.

Our total liability to you for any claim arising from our services shall not exceed the total fees paid by you in the three months preceding the claim.

11. Warranties and disclaimers

We warrant that we will perform our services with reasonable skill and care. We do not warrant that the AI assistant will be error-free, uninterrupted, or that it will meet all of your specific requirements. AI responses are generated automatically and we do not guarantee their accuracy at all times.

12. Governing law

These Terms and Conditions are governed by the laws of the Netherlands. Any disputes arising from these terms shall be subject to the exclusive jurisdiction of the courts of the Netherlands.

13. Changes to these terms

We may update these Terms and Conditions from time to time. Material changes will be communicated to active clients by email with a minimum of 30 days notice. Continued use of our services after that period constitutes acceptance of the updated terms.
