Terms of Service

Last updated: 2026‑05‑10

These Terms are an agreement between Mainframe Computer, Inc. ("Mainframe", "we") and the organization that uses our service ("you"). They cover everything at mainframe.app and its subdomains (including mcp.mainframe.app), the Mainframe GitHub App, and our APIs (the "Service"). The Privacy Policy and the DPA are part of these Terms. If you're accepting on behalf of a company, you confirm you have authority to bind it.

In plain English. You bring video, prompts, voice, and likeness; we host and generate at your direction. You own what you put in and what comes out. Unless you opt out in writing, we may use Customer Content — excluding biometric and likeness materials — to improve Mainframe's AI features, prompts, evals, generation quality, model routing, and models. You're responsible for what you upload, including having permission to use anyone's voice or face. We can suspend accounts that break the Acceptable use rules.

You must be 18 to sign up. The Service is for organizations, not children. You're responsible for your Authorized Users and for any action taken with your credentials, OAuth tokens, Model Context Protocol (MCP) tokens, or installed integrations — if a coding agent uploads a video through your MCP token, that's you. Your Workspace has Admins, whose actions bind it. Notify help@mainframe.app of any suspected unauthorized use.

Your content

Customer Content is everything you put into the Service: uploads, prompts, voice samples, avatar images, brand assets, comments, settings, and credentials. Outputs are what the Service generates from it.

You own your Customer Content and your Outputs. We assign to you whatever Output rights we have, to the extent law and the underlying model's terms allow.

You grant us a worldwide, non‑exclusive, royalty‑free license to use Customer Content only to:

• generate Outputs at your request,
• host content and share it with the audiences you choose,
• route content to the subprocessors listed in the Privacy Policy,
• back up, secure, and operate the Service,
• improve Mainframe's AI features, prompts, evals, generation quality, model routing, and models through Data contribution, unless you opt out in writing,
• compute aggregated, de‑identified statistics about how the Service is used.

That license does not allow us to use biometric or likeness materials for model training without your separate, specific written permission, market the Service using your content without your separate written consent, sell your voice or likeness, or use your content for anything else. The license ends when you delete the content, when the Workspace is deleted, or when these Terms end — except for backups, legal‑hold copies, and Data contribution uses that occurred before a written opt-out took effect. If you send us feedback, we can use it freely.

AI features

Generative features turn an Input into an Output using third‑party models we identify in the Privacy Policy.

• You own your Outputs, subject to the underlying model's terms.
• Outputs may not be unique. Two users with similar Inputs can get similar Outputs. Outputs may be inaccurate or infringe third‑party rights — review them before relying on them.
• Data contribution. Unless you opt out in writing, we may use Customer Content, excluding biometric and likeness materials, to improve Mainframe's AI features, prompts, evals, generation quality, model routing, and models. You may opt out by emailing help@mainframe.app. We will apply your opt‑out prospectively within 30 days.
• Biometric and likeness materials. Voiceprints, facial geometry, voice models, avatar models, and likeness materials are excluded from Data contribution unless you give separate, specific written permission for that use.
• Voice and likeness. When you upload a voice recording or face image, you confirm it is of you, or that you have written permission from the person depicted. We will not commercialize your voice or likeness on a standalone basis without your separate written permission.
• Disclose synthetic media. If an Output identifies or resembles a real person, you'll clearly disclose that it's AI‑generated, in addition to any disclosure required by law (including the EU AI Act).
• Safety review. We may use automated tools and trained reviewers to evaluate suspected violations under appropriate confidentiality. Content flagged for safety or security review may be analyzed to improve abuse detection and enforcement. Content you explicitly submit as feedback may be used to improve the Service.

Sharing and integrations

Each video has an audience: Private, Workspace, Link, or Public. Setting a video to Link or Public authorizes us to make it available to anyone in that audience. You can change the audience or delete a video at any time; cached copies on viewers' devices and search engines may persist.

You can connect the Service to other tools — the GitHub App, OAuth providers, MCP clients, webhooks. By installing or connecting one, you authorize us to exchange Customer Content with it as needed. When an agent acting through your credentials triggers compute or generation in our sandboxes — for example, an MCP client commissioning a video render — the resulting compute usage and Outputs are your responsibility. Third‑party services have their own terms; we're not responsible for them.

Confidentiality

Customer Content is your confidential information. Non‑public information about the Service — pricing, technical roadmap, security designs — is ours. Each party will protect the other's with at least reasonable care and limit access to people and subprocessors who need it. The usual exceptions apply for information that's public, already known, independently developed, or required to be disclosed by law.

Acceptable use

Don't use the Service, and don't let anyone using your credentials use it, to:

• create or distribute illegal content, including child sexual abuse material, content that infringes intellectual property, content that violates publicity or privacy rights, or content prohibited by export controls or sanctions;
• submit anyone's voice, face, or other likeness without their written permission;
• impersonate a person, deceive others about the source of an Output, create election‑deception content, or hide that an Output is AI‑generated when disclosure is required;
• engage in any use prohibited or classified as "high‑risk" under the EU AI Act (Regulation (EU) 2024/1689) without a separate written agreement with us;
• submit data subject to specific legal protection beyond general personal‑data rules — including protected health information regulated by HIPAA, cardholder data regulated by PCI DSS, financial account information regulated by GLBA, or substantially similar regimes — without a separate written agreement with us covering that use;
• train, fine‑tune, or develop any AI service that competes with the Service;
• attack, scan, or test the Service except under a coordinated disclosure agreement; introduce malware; circumvent rate limits or access controls; access other Workspaces' content;
• scrape or extract data except as the documentation expressly permits, or reverse engineer the Service except as law allows.

Report violations to help@mainframe.app; security issues to help@mainframe.app. We will terminate accounts of repeat copyright infringers in appropriate circumstances.

Plans, billing, and termination

Plans are at mainframe.app/pricing. We charge recurring fees in advance and usage fees in arrears. Stripe processes payments. Fees are non‑refundable except where required by law. Past‑due amounts accrue interest at the lesser of 1.5% per month or the legal maximum. We can change fees on 30 days' notice before a renewal term.

You can terminate any time by deleting your Workspace. We can suspend the Service for legal reasons, security risks, non‑payment after notice and a reasonable cure period, or material breach of Acceptable use, and we'll limit suspension to what's necessary. We can terminate for material breach you don't cure within 30 days, or immediately for breach of Confidentiality, Acceptable use, or your insolvency. On termination, the licenses end and Customer Content is deleted as described in the Privacy Policy. Sections that should survive (ownership, confidentiality, indemnities, limits, disputes) survive.

Mainframe IP

The Service, our software, our trademarks, and the documentation are ours. These Terms grant you the right to use the Service as described; all other rights are reserved.

Risk allocation

Disclaimer. Except as these Terms expressly say, the Service is provided "as is" without warranties of any kind. We don't warrant that Outputs are accurate, original, or fit for any particular purpose.

Beta features. Anything we label as beta, preview, alpha, or early access is provided for evaluation only, on an as‑is basis, without warranty or support, and may be changed or discontinued at any time without notice or liability.

Your warranty. You confirm you have all rights and consents needed for us to process your Customer Content — including the consents in AI features — and that your use of the Service complies with these Terms.

Indemnities. You'll defend us against third‑party claims arising from your Customer Content, your use of the Service in violation of these Terms, your failure to obtain a required consent, or your dispute with an Authorized User. We'll defend you against third‑party claims that the Service, used as these Terms allow, infringes a U.S. patent, copyright, or trademark, or misappropriates a trade secret — but not for claims arising from your Customer Content, modifications you make, your combination with other products, Outputs, or your continued use after we provide an alternative.

Liability cap. Each party's total liability is capped at the fees you paid us in the 12 months before the event giving rise to the claim, or US $100 for free use. Neither party is liable for indirect, incidental, special, consequential, or punitive damages. The cap doesn't apply to your fee obligations, the indemnities above, breaches of Confidentiality or Acceptable use, or liability that can't be limited by law.

Disputes

Try us first: send a written notice to help@mainframe.app and allow 30 days to resolve. If that fails, disputes are resolved by binding arbitration administered by the American Arbitration Association under its Commercial Arbitration Rules, seat Wilmington, Delaware. Each party brings claims only on its own behalf — no class or collective actions.

You can opt out of arbitration by emailing help@mainframe.app within 30 days of first accepting these Terms. Either party can bring a small‑claims action or seek injunctive relief in court to protect IP or confidential information. These Terms are governed by Delaware law, without its conflict‑of‑laws rules. The U.N. Convention on Contracts for the International Sale of Goods doesn't apply.

Changes

We may change the Service. If a change materially reduces functionality with material adverse effect on you, you can terminate and get a pro‑rata refund of pre‑paid, unused fees. We may change these Terms; we'll post the new version with a new Last updated date and, for material changes, give 30 days' notice through the Service or to your Workspace Admin. Continued use after the effective date is acceptance.

Other

• Notices to us: help@mainframe.app. Notices to you go to your Admin's email or are posted in the Service.
• Assignment: you can't assign without our consent except to a non‑competing successor in a corporate transaction; we can.
• Subcontractors: we can use them and remain responsible for their performance.
• Force majeure: neither party is liable for events outside its reasonable control.
• Independent contractors: these Terms create no partnership, agency, or employment relationship.
• Severability: unenforceable provisions are modified to the minimum extent needed; the rest stand.
• Export and sanctions: you'll comply, and you confirm you're not on a denied‑party list or in a comprehensively sanctioned country.
• Government use: the Service is "commercial computer software" under 48 C.F.R. §12.212 and §227.7202.
• Entire agreement: these Terms, the Privacy Policy, the DPA, and any signed order form are the whole agreement and supersede earlier communications.
