Terms of Service
The rules of the road.

These Terms govern your use of the ThorStack website ( thorstack.com) and the ThorStack platform — the dedicated deployments we provide to customers. By accessing the website or using a deployment, you agree to these Terms.

ThorStack is provided by Metasession Ltd. (“ThorStack”, “we”). The customer organization that signs the Order Form is the “Customer”.

ThorStack provisions a dedicated per-tenant deployment for each Customer. The deployment includes the modules, integrations, and AI agents specified in the Customer's Order Form.

Each deployment runs on isolated infrastructure (database, app instance, vector store, object storage). Region and architecture are agreed during onboarding.

• Customers are responsible for the actions of users they invite to their deployment.
• Each user must keep credentials confidential. Customers must notify us promptly of any suspected unauthorized access.
• Customers may not share a single user account across multiple individuals.

You agree not to use ThorStack to:

• Violate any law, regulation, or third-party rights (including intellectual property and privacy rights).
• Send unsolicited bulk communications, malware, or content that is fraudulent, defamatory, or harmful.
• Interfere with or disrupt the integrity, security, or performance of the platform.
• Reverse-engineer, decompile, or attempt to extract source code, except to the extent permitted by applicable law.
• Build a competing service using the platform or its outputs.

ThorStack agents may generate emails, content, drafts, and other outputs based on Customer instructions and data. AI outputs:

• Are produced on a best-effort basis and may contain errors, omissions, or biased content.
• Should be reviewed before being relied on for legal, medical, financial, or other consequential decisions.
• Become the property of the Customer once generated, subject to third-party LLM provider terms (where the Customer brings their own LLM keys).

Approval gates are configurable; we recommend conservative defaults for outbound communications and financial actions.

The Customer owns all data they ingest into their deployment. ThorStack processes Customer Data solely to provide the service, under the terms of our DPA at /dpa.

We never train shared AI models on Customer Data. Customer Data stays inside the Customer's tenant.

• Fees are set out in the Customer's Order Form. Plans are priced in USD by default; alternative currencies are available on request.
• Studio and Operator plans are billed monthly in advance. Sovereign plans are billed annually.
• Studio and Operator are month-to-month with a 30-day notice period. Sovereign plans renew annually unless cancelled at least 60 days before the end of the term.
• Late payments accrue interest at 1.5% per month or the maximum permitted by law.

Either party may terminate the agreement for material breach that is not cured within 30 days of written notice. We may suspend access for non-payment or violation of acceptable use, with notice where reasonably possible.

On termination, the Customer can export all data within 30 days. After 30 days, ThorStack will delete Customer Data in accordance with the DPA.

We warrant that the service will perform materially as described in the Order Form and our public documentation. To the maximum extent permitted by law, all other warranties (including implied warranties of merchantability, fitness for a particular purpose, and non-infringement) are disclaimed.

AI outputs are provided as-is and without warranty of accuracy or fitness.

To the maximum extent permitted by law, neither party is liable for indirect, incidental, special, consequential, or exemplary damages, including lost profits, lost data, or business interruption.

Each party's total liability under the agreement is capped at the fees paid by the Customer in the 12 months preceding the event giving rise to the claim. This cap does not apply to a party's indemnification obligations or its breach of confidentiality.

ThorStack will defend the Customer against third-party claims alleging that the platform infringes a US, EU, or UK patent, copyright, or trademark, and pay associated damages.

The Customer will defend ThorStack against third-party claims arising from the Customer's data, content, or use of the platform in violation of these Terms.

These Terms are governed by the laws of England and Wales. Disputes go to the exclusive jurisdiction of the courts of London, except where the Customer is established in a jurisdiction whose laws require otherwise.

We may update these Terms from time to time. Material changes will be posted here and notified to active customers at least 30 days before they take effect.
