Terms of Service

Effective date: April 14, 2026

These Terms of Service (“Terms”) constitute a legally binding agreement between you (“you” or “your”) and SubVault Labs LLC, a Texas limited liability company (“SubVault,” “we,” “us,” or “our”). By accessing or using the SubVault platform, MCP server, website, or any related services (collectively, the “Service”), you agree to be bound by these Terms. If you do not agree, do not use the Service.

1. Overview of the Service

SubVault is a cloud platform that gives AI tools persistent memory. It operates as an MCP (Model Context Protocol) server that AI assistants — such as Claude, Cursor, Copilot, and other MCP-compatible tools — connect to for storing and retrieving structured knowledge. The Service includes the cloud MCP server, vault storage, context assembly engine, optional document connectors, account management, and related support.

Two core operations define the Service: vault (save knowledge from conversations) and remember (retrieve relevant context for new conversations). Your AI tools call these operations on your behalf through the MCP protocol.

2. Eligibility

You must be at least 13 years old (or 16 if you reside in the European Economic Area) to use the Service. By using the Service, you represent and warrant that you meet this age requirement and have the legal capacity to enter into these Terms. If you are using the Service on behalf of an organization, you represent that you have authority to bind that organization to these Terms.

3. Account registration and API keys

To use the Service, you must create an account and receive an API key. Your API key authenticates your AI tools to your SubVault vault. You are responsible for maintaining the security of your API key and for all activity that occurs using it. You agree to:

• Keep your API key confidential and not share it publicly (for example, do not commit it to public repositories).
• Regenerate your API key immediately if you believe it has been compromised.
• Notify us at info@subvault.ai if you become aware of any unauthorized use.

We reserve the right to suspend or terminate accounts that we reasonably believe have been compromised or are being used in violation of these Terms.

4. Your data and intellectual property

You own your data. SubVault does not claim any ownership rights over the knowledge you save to your vault, the documents you connect for processing, or any content you create using the Service. Your vault data is stored in a per-user isolated database that belongs to you.

You grant SubVault a limited, non-exclusive, non-transferable, revocable license to store and process your vault data solely for the purpose of providing the Service — assembling context when your AI tools call remember, deduplicating entries, and maintaining your database. This license terminates when you delete your account.

You represent and warrant that you have the right to store all content you submit to your vault, and that doing so does not violate any third party’s intellectual property rights, privacy rights, or other legal rights.

5. Acceptable use

You agree not to:

• Use the Service for any purpose that is unlawful or prohibited by these Terms.
• Store content in your vault that is illegal in your jurisdiction.
• Attempt to access another user’s vault or data.
• Attempt to reverse-engineer, decompile, or derive the source code of the context assembly engine or extraction models, except where prohibited by applicable law.
• Exceed rate limits (100 requests per minute per API key) or use automated tools to place unreasonable load on the Service.
• Circumvent, disable, or interfere with security-related features of the Service.
• Share, sell, sublicense, or transfer your API key or account access to third parties.
• Use the Service to build a competing product or service, or to benchmark the Service for competitive purposes.
• Use the Service to store or process content that facilitates illegal activity, harassment, or harm to others.

6. Subscription and payment

6.1 Pricing and billing

SubVault offers paid subscription plans as described on our website. The standard plan is $9 per month. Prices are stated in U.S. dollars and are exclusive of applicable taxes. Subscriptions are billed on a recurring monthly basis. We reserve the right to change pricing with at least 30 days’ notice; price changes take effect at the start of your next billing cycle.

6.2 Payment processing

Payments are processed by Stripe, Inc. By subscribing, you authorize Stripe to charge your designated payment method on a recurring basis. You are responsible for keeping your payment information current.

6.3 Cancellation

You may cancel your subscription at any time. Upon cancellation, your access to the Service continues through the end of the current billing period. We do not provide refunds for partial billing periods. After your subscription ends, your vault data remains on our servers for 30 days, during which you may export it. After 30 days, we may delete your vault data.

6.4 Beta and promotional pricing

During early access or beta periods, the Service may be offered for free or at a reduced price. Founding members who signed up during the beta period are grandfathered at their original pricing tier. We will provide at least 30 days’ notice before transitioning from free or promotional pricing to standard pricing.

6.5 Taxes

You are responsible for any applicable sales, use, VAT, or other taxes imposed by your jurisdiction on your subscription, excluding taxes based on our net income.

7. API and MCP usage

The SubVault MCP server is provided for integration with AI tools that support the Model Context Protocol. By connecting an AI tool to SubVault:

• You authorize that tool to read from and write to your vault on your behalf.
• You are responsible for the content those tools save to your vault.
• You acknowledge that SubVault does not control the behavior of third-party AI tools and is not responsible for how they use the context returned by the remember tool.

Rate limits apply per API key: 100 requests per minute. Exceeding rate limits may result in temporary throttling. Persistent or intentional abuse of rate limits may result in account suspension.

8. Intellectual property

The SubVault platform, MCP server, context assembly engine, extraction models, algorithms, website, documentation, trademarks, logos, and all related intellectual property are owned by SubVault Labs LLC or its licensors and are protected by copyright, trademark, and other intellectual property laws. Your use of the Service does not grant you any rights to our intellectual property beyond a limited, non-exclusive, non-transferable, revocable license to use the Service in accordance with these Terms.

9. Privacy

Your use of the Service is also governed by our Privacy Policy, which describes how we collect, use, and protect your information. By using the Service, you acknowledge that you have read and understood the Privacy Policy.

10. Disclaimer of warranties

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, OR COMPLETENESS. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE, OR THAT ANY DEFECTS WILL BE CORRECTED.

WE DO NOT GUARANTEE THE ACCURACY, COMPLETENESS, OR RELIABILITY OF ANY KNOWLEDGE STORED IN OR RETURNED FROM YOUR VAULT. VAULT DATA MAY CONTAIN ERRORS, OMISSIONS, OR OUTDATED INFORMATION. YOU ARE SOLELY RESPONSIBLE FOR VERIFYING ANY INFORMATION BEFORE RELYING ON IT FOR IMPORTANT DECISIONS.

SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES, SO SOME OF THE ABOVE EXCLUSIONS MAY NOT APPLY TO YOU.

11. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL SUBVAULT LABS LLC, ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, OR AFFILIATES BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO LOSS OF PROFITS, DATA, BUSINESS OPPORTUNITIES, OR GOODWILL, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF OR INABILITY TO USE THE SERVICE.

OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID TO US FOR THE SERVICE IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED U.S. DOLLARS ($100).

12. Indemnification

You agree to indemnify, defend, and hold harmless SubVault Labs LLC and its officers, directors, employees, agents, and affiliates from and against any claims, liabilities, damages, losses, costs, and expenses (including reasonable attorneys’ fees) arising out of or in connection with: (i) your use of the Service; (ii) your violation of these Terms; (iii) your violation of any third party’s rights; or (iv) any content you store in your vault or submit for processing.

13. Dispute resolution

13.1 Informal resolution

Before initiating any formal dispute resolution, you agree to first contact us at info@subvault.ai and attempt to resolve the dispute informally for at least 30 days.

13.2 Binding arbitration

If informal resolution is unsuccessful, any dispute arising out of or relating to these Terms or the Service shall be resolved by binding arbitration administered by the American Arbitration Association (“AAA”) under its Consumer Arbitration Rules. The arbitration shall be conducted by a single arbitrator in Austin, Texas (or, at your election, by telephone or videoconference). The arbitrator’s decision shall be final and binding.

13.3 Class action waiver

YOU AND SUBVAULT AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN YOUR OR ITS INDIVIDUAL CAPACITY AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, CONSOLIDATED, OR REPRESENTATIVE ACTION.

13.4 Small claims exception

Either party may bring an individual action in small claims court in Travis County, Texas, for claims within the court’s jurisdictional limits.

13.5 Equitable relief

Nothing in this section prevents either party from seeking injunctive or other equitable relief in any court of competent jurisdiction to prevent infringement or violation of intellectual property rights.

14. Governing law

These Terms shall be governed by the laws of the State of Texas, United States, without regard to conflict of law principles. To the extent arbitration does not apply, the exclusive venue shall be the state and federal courts in Travis County, Texas.

15. Termination

15.1 By you

You may stop using the Service at any time. You may delete your account by contacting info@subvault.ai or through the dashboard. Upon account deletion, we will delete your vault data within 30 days.

15.2 By us

We may suspend or terminate your access immediately if: (i) you materially breach these Terms; (ii) we are required to do so by law; (iii) we reasonably believe your account has been compromised; or (iv) we cease offering the Service. Where practicable, we will provide notice before termination and an opportunity to export your data.

15.3 Effect of termination

Upon termination, your right to use the Service ceases immediately. Sections that by their nature should survive termination will survive, including intellectual property, limitation of liability, indemnification, dispute resolution, and governing law.

16. Service availability

We strive to maintain high availability but do not guarantee that the Service will be uninterrupted or error-free. We may modify, update, suspend, or discontinue any aspect of the Service at any time. If we discontinue a material feature, we will provide reasonable notice by email.

17. Force majeure

Neither party shall be liable for any failure or delay in performance resulting from causes beyond its reasonable control, including acts of God, natural disasters, pandemics, war, terrorism, government actions, power failures, internet disruptions, or third-party service provider outages.

18. Export control

You agree to comply with all applicable export and import control laws and regulations. You represent that you are not located in, or a resident or national of, any country subject to U.S. trade sanctions, and that you are not on any U.S. government restricted party list.

19. General provisions

19.1 Entire agreement

These Terms, together with the Privacy Policy, constitute the entire agreement between you and SubVault regarding the Service.

19.2 Severability

If any provision is held invalid or unenforceable, that provision shall be enforced to the maximum extent permissible, and the remaining provisions continue in full force.

19.3 Waiver

Our failure to enforce any provision shall not constitute a waiver.

19.5 Notices

We may provide notices via email or prominent notice on the website. Notices to us should be sent to info@subvault.ai.

20. Changes to these Terms
