Terms of Service

Last updated: 12 May 2026

These Terms of Service ("Terms") govern your access to and use of the Quelvio service ("Service") provided by Rolle Ltd, a company registered in England and Wales (company number 14560691), with registered office at 71–75 Shelton Street, Covent Garden, London WC2H 9JQ, United Kingdom ("Quelvio", "we", "us", "our").

By accessing or using the Service, you agree to be bound by these Terms. If you are entering into these Terms on behalf of an organisation, you represent that you have authority to bind that organisation, and "you" refers to that organisation.

If you do not agree to these Terms, do not use the Service.

1. The Service

Quelvio provides an enterprise knowledge platform that connects to your organisation's existing systems (such as Google Drive, SharePoint, Confluence, Slack, Notion, and other supported sources), indexes the content with authority and lifecycle awareness, and returns cited answers to natural-language queries. The Service is delivered as a hosted cloud application, with optional access through Model Context Protocol ("MCP") clients including Claude, Cursor, and similar AI assistants.

We may modify, suspend, or discontinue any part of the Service at any time, with reasonable notice for material changes as set out in Section 17.

2. Accounts and access

To use the Service, you must create an account or be invited to an organisation that has done so. You are responsible for:

Maintaining the confidentiality of your account credentials and API keys
All activity that occurs under your account
Promptly notifying us of any unauthorised access at [email protected]

Each organisation ("Tenant") on the Service operates within an isolated environment. Cross-tenant access is structurally prevented.

We may suspend or terminate accounts that violate these Terms, present a security risk, or engage in fraudulent activity.

3. Acceptable use

You agree not to:

Use the Service for any unlawful purpose or in violation of any applicable law
Upload, index, or transmit content that infringes intellectual property rights, contains malware, or violates privacy rights of others
Attempt to gain unauthorised access to the Service, other Tenants' data, or our infrastructure
Reverse engineer, decompile, or attempt to derive source code of the Service except where permitted by law
Use the Service to develop a competing product
Exceed reasonable usage limits or attempt to circumvent rate limits
Use the Service to generate content that violates applicable laws or these Terms

4. Your content and data

You retain all rights, title, and interest in the content you upload, connect, or generate through the Service ("Your Content"). You grant us a limited, non-exclusive licence to process Your Content solely for the purpose of providing the Service to you — including indexing, retrieval, embedding generation, and synthesis of cited answers.

We do not:

Sell Your Content to third parties
Use Your Content to train, fine-tune, or otherwise improve any AI model
Access Your Content except as needed to provide and support the Service

You are responsible for ensuring you have the right to provide Your Content to the Service, including rights from any third parties whose content is contained within it.

5. Source system integrations

When you connect a third-party source (such as Google Drive or SharePoint), you authorise us to access that source according to the permissions you grant via OAuth or API credentials. We honour the access control rules of the underlying source system — content visible to a user in the source is the same content visible to that user through the Service.

We are not responsible for changes to third-party services, their availability, or modifications to their APIs.

6. Pricing and Knowledge Tokens

The Service is priced using a unit called a Knowledge Token ("kT"), with current rates published at https://quelvio.com/pricing and reflected in your account dashboard. Pricing has three dimensions:

Ingestion — one-time charges when content is indexed
Index — daily accrual for ongoing storage and synchronisation
Retrieval — per-query charges that vary by query mode

Rates may be updated from time to time. Material rate changes will be communicated with at least 7 days' notice via email or in-product notification. Continued use of the Service after a rate change takes effect constitutes acceptance.

You agree to pay all charges incurred by your Tenant. Charges are billed in arrears or as otherwise specified in your plan.

7. Free tier

Quelvio offers a free tier subject to the following limits:

Up to 5 GB of indexed content
Up to 2 queries per day

Free-tier accounts may be subject to additional limitations communicated in your account dashboard. These limits may be adjusted from time to time with at least 7 days' notice. Current free-tier and paid-plan details are published at https://quelvio.com/pricing.

If your usage exceeds free-tier limits, you may be required to subscribe to a paid plan. Free-tier data is subject to the same security, privacy, and retention practices as paid-tier data.

8. Intellectual property

The Service, including all software, designs, documentation, and trademarks, is owned by Rolle Ltd or its licensors and is protected by intellectual property laws. We grant you a limited, non-exclusive, non-transferable licence to use the Service in accordance with these Terms.

Any feedback, suggestions, or ideas you provide about the Service may be used by us without restriction or compensation.

The Quelvio MCP server source code is published under the MIT license; usage of the Quelvio hosted service through the MCP server is governed by these Terms.

9. Confidentiality

Each party agrees to protect the other's confidential information with reasonable care and to use it only to perform obligations under these Terms. Confidential information does not include information that is publicly available, independently developed, or rightfully received from a third party without confidentiality obligations.

10. Privacy

Our handling of personal data is described in our Privacy Policy, which is incorporated into these Terms by reference. Where you process personal data through the Service as a data controller, we act as a data processor on your behalf. Data Processing Agreement availability, data export rights, retention timelines, sub-processors, and cross-border data transfer mechanisms are described in our Privacy Policy.

11. Security

We implement industry-standard administrative, technical, and physical safeguards to protect Your Content, including encryption in transit and at rest, tenant isolation, access controls, and audit logging. Detailed security measures are described in our Privacy Policy.

No system is perfectly secure. You acknowledge that no transmission over the internet or storage method is 100% secure.

If you become aware of a security incident affecting your account, contact us immediately at [email protected].

12. Third-party services

The Service integrates with third-party services (such as the source systems you connect, AI model providers we use to power synthesis, and infrastructure providers). Your use of those third-party services is governed by their own terms. Sub-processors are listed in our Privacy Policy. We are not responsible for third-party services' availability, performance, or content.

13. Warranties and disclaimers

The Service is provided "as is" and "as available". To the maximum extent permitted by law, we disclaim all warranties, whether express, implied, statutory, or otherwise, including warranties of merchantability, fitness for a particular purpose, and non-infringement.

We do not warrant that:

The Service will be uninterrupted or error-free
Defects will be corrected
The Service or the servers that make it available are free of viruses or harmful components
Search results, synthesised answers, or citations will be complete, accurate, or suitable for any particular purpose

You acknowledge that AI-generated content may contain errors, omissions, or biases. You are responsible for reviewing and verifying any output before relying on it.

14. Limitation of liability

To the maximum extent permitted by law, in no event will Rolle Ltd, its affiliates, officers, employees, agents, or licensors be liable for any indirect, incidental, special, consequential, or punitive damages, including loss of profits, data, use, goodwill, or other intangible losses, arising from or relating to your use of the Service.

Our total liability for any claim arising out of or relating to these Terms or the Service shall not exceed the total fees paid by you to us in the twelve months preceding the event giving rise to the claim. For free-tier users who have not paid any fees, our total liability is limited to the maximum extent permitted by law.

Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law, including liability for death, personal injury caused by negligence, fraud, or fraudulent misrepresentation.

15. Indemnification

You agree to indemnify, defend, and hold harmless Rolle Ltd and its affiliates, officers, employees, agents, and licensors from and against any claims, damages, losses, liabilities, costs, and expenses (including reasonable legal fees) arising out of or relating to:

Your use of the Service in violation of these Terms or applicable law
Your Content
Your violation of any third-party right

16. Term and termination

These Terms remain in effect while you use the Service. Either party may terminate:

For cause, on notice if the other party materially breaches these Terms and fails to cure within 30 days
For convenience, by closing your account or, where applicable, by giving notice in accordance with your plan

On termination:

Your access to the Service ceases
Your Content is retained and deleted in accordance with the retention periods described in our Privacy Policy
Provisions that by their nature should survive (including intellectual property, confidentiality, limitations of liability, indemnification, and governing law) will survive

You may request data deletion at any time as described in our Privacy Policy.

17. Changes to these Terms

We may update these Terms from time to time. Material changes will be communicated by email or in-product notice at least 30 days before they take effect. Changes to pricing and Knowledge Token rates are governed separately by Section 6 (at least 7 days' notice). Your continued use of the Service after changes take effect constitutes acceptance of the updated Terms.

18. Governing law and jurisdiction

These Terms are governed by the laws of England and Wales, without regard to conflict of law principles. Any dispute arising out of or relating to these Terms or the Service shall be subject to the exclusive jurisdiction of the courts of England and Wales, except that we may seek injunctive relief in any court of competent jurisdiction.

If you are a consumer based in the European Union, you may also have the right to bring proceedings in the courts of your country of residence under applicable consumer protection laws.

19. General

Entire agreement: These Terms, together with our Privacy Policy and any order form or supplemental terms, constitute the entire agreement between you and us regarding the Service.
Assignment: You may not assign these Terms without our prior written consent. We may assign these Terms in connection with a merger, acquisition, or sale of assets.
No waiver: Our failure to enforce any provision does not constitute a waiver of that provision.
Severability: If any provision is held unenforceable, the remaining provisions will continue in effect.
Notices: Notices to us should be sent to [email protected]. Notices to you may be sent to the email address on file for your account.
Force majeure: Neither party is liable for delays or failures due to events beyond reasonable control, including natural disasters, war, terrorism, civil unrest, government action, labour disputes, or infrastructure failures affecting third-party providers.
