Terms of Service

Effective date: May 10, 2026
Version: 2026-05-10

Draft notice: Adapted from the Basecamp open-source policies (CC BY 4.0). Operational facts (legal entity, contact, hosting, retention windows, governing law) are filled in. Items still requiring qualified legal review before launch are tracked in the project’s internal legal/COUNSEL_REVIEW_CHECKLIST.md. Do not rely on this document as final legal protection until counsel sign-off.

From everyone working on Knotr AI, thank you for using the product. We built it to help you keep one source of truth — your profiles, knowledge, and skills — and reuse it across the AI tools you already use. Because we don’t know every customer personally, we’ve put a few Terms of Service in place to keep things running smoothly for everyone.

When we say “Knotr,” “we,” “our,” or “us,” we mean Knotr AI, LLC, 821 Jameison Road, Lutherville Timonium, MD 21093, USA.

When we say “Service,” we mean the Knotr AI website, web application, MCP and API endpoints, and any related software we operate.

When we say “you” or “your,” we mean the person or organization that owns a Knotr AI account. If you accept these Terms on behalf of an organization, you confirm you have authority to bind that organization, and “you” includes that organization.

We may update these Terms in the future. When we make a material change, we will refresh the Effective date and Version above, bump the version stored in Legal::TERMS_VERSION in our source code, and take other reasonable steps to notify account holders (for example, in-product notice or email). Continued use of the Service after the new effective date means you accept the updated Terms. These Terms contain a limitation of liability.

If you violate these Terms, we may suspend or terminate your account. That is a broad statement and asks for trust on your part. We do our best to deserve that trust by being clear about what we collect, who touches it, and how to reach us.

Account terms

  1. You are responsible for maintaining the security of your account and credentials, and for any activity under your account. We strongly recommend you use a unique, strong password and enable any additional security features we offer.
  2. You may not use the Service for any purpose listed in our Acceptable Use Policy, and you may not let anyone you invite do so either.
  3. You are responsible for all content posted to and activity under your account, including content posted by team members you invite.
  4. You must be a human. Accounts registered by bots or other automated methods are not permitted, except for accounts that you operate yourself through our published API or MCP endpoints.
  5. You must be at least 16 years old to use the Service. The Service is not directed to children below that age.

User Content

The text, files, prompts, profiles, knowledgebases, skill definitions, and other materials you submit to the Service (your “User Content”) belong to you. We do not claim ownership over any of it.

You grant Knotr a limited, non-exclusive, worldwide license to host, store, reproduce, process, transmit, display, and create technical derivatives of your User Content (such as search indexes and embeddings stored in our vector database) for one purpose: operating, securing, and supporting the Service for you. We do not sell your User Content. We do not use your User Content to train Knotr’s own foundation models. Knotr uses OpenAI through OpenAI’s standard API, where OpenAI’s published API data-usage policy (effective since March 1, 2023) states that OpenAI does not use API inputs or outputs to train its models. We do not use ChatGPT consumer plans, where different terms can apply.

You represent that:

  • You have the rights necessary to submit your User Content to the Service.
  • Your User Content and your use of the Service comply with applicable law and the Acceptable Use Policy.
  • You will not upload special categories of personal data (for example, health data, government IDs, payment card numbers) unless we have agreed to support that in writing.

Team workspaces

If you create or join a team workspace, the team’s administrators control roles, invitations, billing, and member access for that workspace. Administrators can see content within the workspace and may revoke member access at any time. If a team workspace is on a paid plan, the workspace owner is responsible for payment.

When you act inside a team workspace, the team is the controller of the User Content stored there, and Knotr is a processor acting on the team’s instructions (see our Data Processing Agreement template).

MCP, API access, and third-party clients

A core feature of Knotr AI is exposing your skills to third-party AI clients through the Model Context Protocol (MCP) and our HTTP API. We want this to be powerful, and we also want the boundaries to be clear.

  1. You decide what to expose. You choose which skills are MCP-exposed and which clients you connect using API keys or OAuth. You can revoke access at any time from your account settings.
  2. You are responsible for the third-party clients you connect. Knotr does not control external MCP hosts, IDEs, or AI assistants. Their actions, terms, and security practices are between you and them.
  3. Fair use and rate limits. We may apply rate limits, quotas, or other technical controls to protect the Service. We may suspend access for any client whose traffic threatens the security, stability, or lawful use of the Service.
  4. Abuse suspension. We may suspend a specific API key, OAuth client, or MCP endpoint without notice if we believe it is being used to harm Knotr, our customers, or third parties. We will tell the account owner what happened as soon as it is safe to do so.

AI features and outputs

Several Knotr features use third-party AI models (currently OpenAI) to generate outputs, including in-product Skill AI chat, prompt suggestions, and skill execution. A few things to keep in mind:

  • Outputs may be wrong. Generated text can be inaccurate, biased, or out of date. Treat AI output as a starting point that you must review.
  • No professional advice. Knotr AI does not provide legal, medical, financial, tax, or other professional advice. Do not rely on AI output for high-stakes decisions without qualified human review.
  • Your responsibility for what you publish. If you expose a skill to others through MCP or share AI-generated content elsewhere, you are responsible for what it produces and for complying with applicable disclosures.
  • Provider changes. We may swap, add, or change the AI providers and models we use to keep the Service reliable and cost-effective. Material changes will be reflected in our Subprocessor list.

Acceptable use

You must use the Service in compliance with applicable law and our Acceptable Use Policy. We may suspend or terminate access for violations or for risk to the Service or other users.

Payment, refunds, and plan changes

  1. Free plans, where offered, are really free: we do not require a credit card and we do not sell your data.
  2. For paid plans, we charge in advance for each billing cycle through our payment processor, Stripe. If your payment fails, we may freeze your account until payment succeeds.
  3. If you upgrade from a free to a paid plan, we charge your payment method immediately and your billing cycle starts on the day of upgrade. For other upgrades or downgrades, the new rate starts from the next billing cycle.
  4. All fees are exclusive of taxes, levies, or duties. Where required, we will collect and remit those taxes; otherwise, you are responsible for them.
  5. Refunds. If you are unhappy with the Service for any reason, contact us at support@knotr.ai and we will do our best to make it right. As a default, we offer a refund of the most recent monthly charge if you ask within 30 days, and prorated credits in other reasonable cases. Refund handling outside the EU/UK is otherwise at our discretion; mandatory consumer-protection rights in your country always apply.
  6. Auto-renewal. Subscriptions renew automatically until you cancel them in-product. You can cancel at any time from your billing settings; cancellation takes effect at the end of your current paid period unless we agree otherwise.

Cancellation and termination

  1. You can cancel your account at any time from your account settings. We will not bill you again after cancellation.
  2. After you cancel, your User Content becomes inaccessible to you and is queued for deletion. Within 30 days, your User Content is permanently deleted from our active systems and logs. Within 60 days, it is also deleted from our backups, except where we are required by law to retain billing or tax records.
  3. If you want a copy of your data, export it before cancelling. Once it is deleted from active systems, we cannot recover it for you.
  4. We may suspend or terminate your account if you breach these Terms, fail to pay fees, or use the Service in a way that risks harm to Knotr, our customers, or third parties. Suspension means you cannot access your account; termination also deletes the account.
  5. Verbal, physical, written, or other abuse — including threats — directed at any Knotr employee, contractor, or community member will result in immediate termination of your account.

Modifications to the Service and prices

  1. We may modify or discontinue features at any time. Where a change materially reduces a feature you depend on, we will give reasonable notice through in-product messaging or email when we are able to.
  2. We may change pricing for new and existing customers. For existing paid customers, we will give at least 30 days’ notice by email before a price change takes effect, unless you are on a plan that explicitly states otherwise.

Uptime, security, and privacy

  1. Your use of the Service is at your sole risk. We provide the Service on an “as is” and “as available” basis. We do not currently offer service-level agreements outside of contracts negotiated with team or enterprise customers.
  2. We take many measures to protect your data, including encryption in transit, access controls, and routine backups. See the relevant sections of our Privacy Policy and the security summary in our Data Processing Agreement template.
  3. You agree that Knotr may process your data as described in the Privacy Policy, and only for the purposes described there. Specifically, Knotr team members may access your data:
    • To help you with support requests you make. We will ask for your express consent before opening your User Content.
    • To investigate errors that stop an automated process. We aim to fix issues from logs and metadata first; we look at the minimum amount of personal data necessary, and we work to prevent the error from recurring.
    • To safeguard the Service. We review logs and metadata to keep the Service secure. If necessary, we may also access an account as part of an investigation under the Acceptable Use Policy.
    • To the extent required by applicable law. We comply only with valid legal process, and we tell affected users when we are not legally prohibited from doing so.
  4. We use third-party vendors and hosting partners to provide the Service. The current list is at /subprocessors.

Copyright and content ownership

  1. Content posted on the Service must comply with applicable copyright law. To report alleged infringement, email support@knotr.ai.
  2. You give us the limited license described in the User Content section above so that we can provide the Service to you. We claim no ownership in your materials.
  3. We do not pre-screen content, but we reserve the right (and not the obligation) to refuse or remove content that violates these Terms or the Acceptable Use Policy.
  4. The Service, including its software, designs, documentation, and Knotr branding (the “Knotr Materials”), is owned by Knotr and its licensors. You receive only the limited rights expressly granted in these Terms. You may not duplicate, copy, or reuse our HTML, CSS, JavaScript, or visual design elements without written permission. To use our logos for promotional purposes, ask us first at support@knotr.ai.

Features and bugs

We design the Service with care and we test new features before shipping. As with any software, bugs happen. We track reported bugs and prioritize anything affecting security or privacy. We do not guarantee a defect-free Service or that the Service will meet every specific requirement you have.

API and integration terms

In addition to the rest of these Terms, the following apply to our API and MCP endpoints:

  1. We are not liable for damages or losses arising out of your use of the API, the MCP endpoints, or any third-party application that uses them on your behalf.
  2. Third-party developers may not use the API or MCP endpoints to build products that secretly surveil end users, or to scrape data from accounts you do not own.
  3. Excessive or abusive request volume may result in temporary or permanent suspension of API or MCP access. We will attempt to warn the account owner first; we may cut off access without prior notice if your usage causes or could cause downtime.

Liability

We mention liability throughout these Terms; here is the consolidated version:

You expressly understand and agree that Knotr will not be liable, in law or in equity, to you or to any third party for any indirect, incidental, special, consequential, punitive, or exemplary damages, or for any loss of profits, revenue, goodwill, data, or other intangible losses (even if Knotr has been advised of the possibility of such damages), arising out of or related to: (i) your use of, or inability to use, the Service; (ii) the cost of substitute goods and services; (iii) unauthorized access to or alteration of your data; (iv) statements or conduct of any third party (including third-party MCP or AI clients you connect); or (v) any other matter relating to these Terms or the Service, whether based in contract, tort (including negligence), or any other theory of liability.

Knotr’s total cumulative liability for any claim arising out of or related to the Service will not exceed the greater of (a) the amounts you paid Knotr for the Service in the twelve (12) months before the event giving rise to the claim, or (b) **USD 100**.

Some jurisdictions do not allow certain limitations of liability; in those places, our liability is limited to the maximum extent permitted by law.

Indemnity

You will defend and indemnify Knotr and its affiliates, officers, employees, and agents from third-party claims and liabilities arising from (a) your User Content, (b) your misuse of the Service or violation of these Terms or applicable law, or (c) your authorization of third-party clients (including MCP and AI clients) to act on your behalf. Knotr will give you prompt written notice of any claim, allow you to control the defense (with counsel reasonably acceptable to Knotr), and provide reasonable assistance at your expense. You may not settle any claim that imposes liability or admission of wrongdoing on Knotr without Knotr’s prior written consent.

General

Changes. We may update these Terms by posting a new version and updating the effective date. Where required by law, we will give additional notice. Continued use after the effective date constitutes acceptance.

Governing law and venue. These Terms are governed by the laws of the State of Delaware, without regard to its conflict-of-laws principles. Any dispute arising out of or relating to these Terms or the Service that is not resolved informally will be brought exclusively in the state or federal courts located in New Castle County, Delaware, and you and Knotr each consent to personal jurisdiction in those courts. Where applicable consumer-protection law gives you the right to bring an action in the courts of your country of residence, those rights are not affected. Nothing in these Terms prevents either party from seeking injunctive relief in any court of competent jurisdiction to protect its intellectual property or confidential information.

Assignment. You may not assign these Terms without our consent. We may assign them in connection with a merger, acquisition, or sale of all or substantially all of our assets.

Force majeure. Neither party is liable for failures caused by events outside its reasonable control.

Entire agreement; severability; waiver. These Terms, together with the Privacy Policy, Acceptable Use Policy, Cookie Notice, Subprocessor list, and (where applicable) the Data Processing Agreement, are the entire agreement between you and Knotr about the Service. If a provision is unenforceable, the rest remains in effect. Failure to enforce a provision is not a waiver of that provision.
