Terms of Service

Last updated: April 30, 2026

These Terms of Service ("Terms") govern your access to and use of MARIN's websites, applications, and related services (collectively, the "Service"). The Service includes AI-assisted workflows, connections to third-party accounts (such as Google, Microsoft, and Dropbox), optional integrations (such as Notion, GitHub, LinkedIn, Instagram, X, and Zoom), web research and crawling capabilities (including through vendors such as Firecrawl and AI providers like Anthropic and OpenAI), and authentication through Clerk. By using the Service, you agree to these Terms and to our Privacy Policy.

1. Agreement and eligibility

  • You agree to these Terms on behalf of yourself and, if you use the Service on behalf of a company or other entity, you represent that you have authority to bind that entity, in which case "you" includes that entity.
  • You must be at least the age of majority in your jurisdiction (and at least 13 years old). If you are between 13 and the age of majority, you may use the Service only with a parent or guardian's consent where required by law. The Service is not intended for children under 13.
  • You are responsible for ensuring that your use of the Service complies with the laws and regulations that apply to you, including workplace, industry, and data-protection requirements (for example HIPAA, export controls, or sector rules) if you handle regulated data.

2. Description of the Service

MARIN provides an AI-powered assistant that can help you work across tools you connect. Depending on your plan and configuration, the Service may include:

  • Email-related assistance (for example drafting, sending, organizing, or searching mail)
  • Calendar and scheduling assistance
  • File and document workflows (including cloud storage providers you connect)
  • Web research, retrieval of public web pages, and analysis of URLs or search results you request
  • Task automation, reminders, permissions, and approval flows you configure
  • Organization or workspace features, seat management, and administrative controls (where available)
  • Integrations with third-party platforms when you authorize them

We may modify, suspend, or discontinue features (including integrations or model providers) to improve security, comply with law, or reflect changes by third parties. We will provide reasonable notice where practicable for material changes that adversely affect paying customers, unless immediate action is required for legal or security reasons.

3. Accounts, credentials, and security

  • Accounts and sign-in may be provided through our authentication vendor (Clerk). You must provide accurate registration information and keep it current.
  • You are responsible for safeguarding credentials and for all activity under your account unless caused by our gross negligence or willful misconduct.
  • If you use a workspace or organization, your administrators may have additional controls (such as access, retention, or export policies). Their actions may affect your use of the Service.
  • Notify us promptly at cyrus@heymarin.ai if you suspect unauthorized access.

4. Third-party accounts, OAuth, and your instructions

  • The Service may connect to third-party services you authorize (including without limitation Google Workspace or Gmail, Microsoft 365 or Outlook, Dropbox, Notion, GitHub, LinkedIn, Instagram, X, and Zoom). Those connections are governed by the third party's terms and privacy policies in addition to these Terms.
  • You grant MARIN permission to access, store, and process information from connected accounts as needed to perform actions you request or that you configure (including automated or scheduled actions and actions subject to approval flows you enable).
  • You represent that you have the rights and authority to connect those accounts and to instruct us to access and act on the data within them, including for your employer's accounts where applicable.
  • We are not responsible for outages, rate limits, policy changes, revocations, or errors originating from third-party platforms. Features that depend on a third-party API may stop working without notice when the third party changes or revokes access.
  • When you submit URLs or ask us to retrieve public web content, you represent that doing so does not violate applicable law or the rights of others, and that you have any permissions needed for us to fetch or process that content on your behalf.

5. AI outputs, automation, and human review

  • The Service uses artificial intelligence and may use model providers and tools (such as Anthropic, OpenAI, web search or browsing tools, and crawling or extraction services such as Firecrawl). AI outputs may be incorrect, incomplete, or inappropriate. You are solely responsible for reviewing outputs before relying on them or before they are sent, posted, or used to modify data in connected accounts.
  • The Service is not a substitute for professional advice (legal, medical, financial, tax, or otherwise). You should consult qualified professionals for decisions with significant consequences.
  • You are responsible for actions taken through the Service, including messages sent, files changed, calendar events created or modified, and posts or API calls made on your behalf, whether or not you personally reviewed each step.
  • Where the product offers approvals, permissions, or safeguards, you remain responsible for configuring them appropriately for your risk tolerance and regulatory obligations.

6. Your content and license to us

  • You retain ownership of your content. You grant MARIN a worldwide, non-exclusive license to host, use, reproduce, adapt, process, transmit, and display your content solely to provide, secure, and improve the Service, including to train or fine-tune models where permitted by your settings and our Privacy Policy.
  • You represent that you have all rights necessary to provide your content and that your content does not violate law or third-party rights.

7. Acceptable use

You agree not to:

  • Violate applicable law or regulation, or infringe others' intellectual property or privacy rights
  • Use the Service to send spam, phishing, malware, deceptive content, or harassing communications, or to circumvent email or messaging provider policies
  • Attempt to probe, scan, or test the vulnerability of our systems, or bypass authentication or rate limits, except as part of an authorized bug bounty program we approve in writing
  • Reverse engineer, decompile, or attempt to extract source code or models except where prohibited by law
  • Use the Service to build a competing product by systematically scraping, harvesting, or replicating the Service or its users' data without authorization
  • Misrepresent your identity or affiliation, or access another user's account without permission
  • Use the Service in violation of any third-party terms that apply to data you process through connected integrations (including Google or Microsoft API policies)
  • Use the Service in a manner that imposes an unreasonable load on our infrastructure

We may investigate violations and cooperate with law enforcement or regulators as required.

8. Privacy, analytics, and subprocessors

Our collection and use of personal information is described in our Privacy Policy, including subprocessors such as cloud infrastructure (for example AWS), authentication (Clerk), AI providers (for example Anthropic and OpenAI), web crawling tools (for example Firecrawl), analytics tags (for example Google Tag Manager), and other vendors listed there. By using the Service, you consent to those practices.

9. Fees, trials, taxes, and changes

  • Some features require a paid plan. Fees, billing cycles, seat counts, and renewal terms are presented at purchase or in your account (including the billing area of the dashboard) and may be updated prospectively with reasonable notice where required.
  • Unless stated otherwise at checkout or in an order form, subscription fees are billed in advance, are non-cancelable for the current term except as required by law, and are exclusive of taxes, which you are responsible for where applicable.
  • If we offer a free trial, it converts to a paid subscription only if you elect to continue according to the flow we present. Downgrades or cancellations may take effect at the end of the then-current billing period unless we specify otherwise.
  • Promotional refund policies (for example a money-back window) apply only if and as described on our website or in writing at the time of purchase, and do not limit any non-waivable statutory rights.

10. Intellectual property

  • MARIN and its licensors own the Service, including software, branding, documentation, and templates, subject to your rights in your content and any open-source components we identify.
  • Except for the limited rights expressly granted in these Terms, no licenses are granted by implication or estoppel.
  • If you provide feedback or suggestions, you grant us a perpetual, irrevocable, royalty-free license to use them without obligation to you.

11. Suspension and termination

  • You may stop using the Service at any time. You may also disconnect integrations and request account deletion according to tools we provide or by contacting support.
  • We may suspend or terminate access if you materially breach these Terms, if we must do so to comply with law or a platform policy, or if continued provision would create security or legal risk. We will use reasonable efforts to provide notice where practicable, except for emergencies or repeat abuse.
  • Upon termination, your right to access the Service ceases. We may delete or retain data as described in our Privacy Policy and applicable law. Provisions that by their nature should survive (including Sections 5–8, 10, and 12–18) will survive termination.

12. Disclaimers

To the maximum extent permitted by law, the Service is provided "as is" and "as available," without warranties of any kind, whether express, implied, or statutory, including implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement.

We do not warrant that the Service will be uninterrupted, error-free, or free of harmful components, or that AI outputs will be accurate or suitable for any purpose.

13. Limitation of liability

To the maximum extent permitted by law, MARIN and its suppliers will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, revenues, data, or goodwill, arising out of or related to the Service or these Terms, even if advised of the possibility.

To the maximum extent permitted by law, our aggregate liability for all claims arising out of or relating to the Service or these Terms will not exceed the greater of (a) the amounts you paid to MARIN for the Service in the twelve (12) months before the event giving rise to liability, or (b) one hundred U.S. dollars (USD $100) if you have not paid fees.

Some jurisdictions do not allow certain limitations; in those cases, our liability is limited to the fullest extent permitted by applicable law.

14. Indemnification

You will defend, indemnify, and hold harmless MARIN and its affiliates, officers, directors, employees, and agents from and against any claims, damages, losses, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of or related to your content, your use of the Service, your violation of these Terms, or your violation of third-party rights or law. We may assume exclusive defense and control of any matter subject to indemnification by you, at your expense, and you will cooperate with our reasonable requests.

15. Export, sanctions, and government users

You may not use or export the Service except as authorized by United States law and the laws of your jurisdiction. You represent that you are not located in, or ordinarily resident in, a country or region subject to comprehensive U.S. sanctions, and that you are not on any restricted party list. If you are a U.S. government entity, additional terms may apply as required by applicable regulations.

16. Disputes, governing law, and venue

These Terms are governed by the laws of the State of Delaware and the United States, without regard to conflict-of-law principles. Subject to non-waivable rights you may have under local consumer protection law, you and MARIN consent to the exclusive jurisdiction and venue of the state and federal courts located in Delaware for disputes arising out of or relating to these Terms or the Service.

17. General

  • Entire agreement. These Terms and the Privacy Policy are the entire agreement between you and MARIN regarding the Service and supersede prior understandings on this subject, except for a signed enterprise agreement that explicitly overrides specific provisions.
  • Assignment. You may not assign these Terms without our consent. We may assign these Terms in connection with a merger, acquisition, or sale of assets.
  • No waiver; severability. Failure to enforce a provision is not a waiver. If a provision is unenforceable, the remaining provisions remain in effect.
  • Notices. We may provide notices through the Service, by email to the address associated with your account, or by posting updates to these Terms.
  • Force majeure. We are not liable for delays or failures caused by events beyond our reasonable control.

18. Changes to these Terms

We may update these Terms from time to time. We will post the revised Terms on this page and update the "Last updated" date. If changes are material, we will provide additional notice as appropriate (for example, by email or in-product notification). Your continued use after the effective date of updated Terms constitutes acceptance, except where non-waivable law requires explicit consent.
