Terms of service.

The agreement that governs your use of gbrain.io.

These terms govern access to gbrain.io, operated by The Overton Window Company, Inc. (“we,” “us,” “Overton”). They apply to anyone who creates an account or uses the service (“you,” “Customer,” “your organization”).

Customers who need a signed MSA, a DPA, or other contractual language can reach us at legal@overton.xyz.

1. The service

gbrain.io provides hosted “brains,” which are agent runtimes that crawl public sources, summarize them, and surface findings to your team. Each brain runs in an isolated compute environment we provision and operate. The full architecture is described in Security; the data we process is described in Privacy.

We may add, change, or remove features. We won’t degrade core functionality you’re paying for without notice; we will iterate on what’s around it.

2. Accounts and authentication

Sign-in is via Google OAuth. Each user account is identified by the email address Google asserts. You’re responsible for the security of the Google account you use to sign in.

A workspace (also called an “organization”) is the billing and membership unit. One user is the payor for each workspace; that user’s billing relationship covers the workspace’s brains. Other users join the workspace as admins or members. Admins can create and delete brains; members can use them. Removing a member from a workspace doesn’t delete brains the workspace owns.

You’re responsible for who you invite into your workspace and what they do there. We don’t review invites.

3. Acceptable use

Don’t use the service to:

  • Violate the law of any jurisdiction that applies to you or to us.
  • Break into, scan, or interfere with systems you don’t have permission to access.
  • Crawl sources whose terms of service prohibit automated access.
  • Harass, defame, or harm other people.
  • Train a competing AI model on outputs the service generates.
  • Resell access to the service to third parties without our written agreement.

We can suspend a workspace that we believe is doing any of the above. We’ll tell you why and give you a chance to respond, except in cases where doing so would create immediate harm.

4. Customer data

Customer data means anything your workspace’s brains ingest, generate, or store. This includes the raw content brains pull from connected sources, the notes and summaries they write, and any configuration you provide.

You own your customer data. We don’t claim license to it beyond what we need to actually operate the service for you (host it, transmit it between components, send it to the AI model that processes it on your behalf, return it to you). We don’t train models on it. We don’t share it with anyone outside the subprocessor list in Privacy.

When you delete a brain, the customer data on it is destroyed on the timeline described in Privacy.

5. Subscription, billing, and term

Plans, prices, and what each plan includes are listed in the workspace’s billing area. We use Stripe for payment processing.

  • Subscriptions renew automatically until you cancel.
  • Cancellation takes effect at the end of the current billing period; we don’t pro-rate refunds for unused time.
  • Material price changes for an existing plan get at least 30 days’ email notice.
  • Failed payments may result in suspension; we’ll email you before suspending and again at the suspension itself.

If your workspace owes us money and you stop paying, we may eventually delete the brains in that workspace after reasonable notice.

6. Service availability

The service does not include a contractual uptime SLA today. Until one is in place:

  • We notify customers of unplanned downtime by email when it exceeds a few minutes.
  • We do best-effort restoration. We do not credit accounts for downtime today.
  • We publish a written post-mortem after any incident that affects customer data or causes downtime longer than 30 minutes.

If your use case requires a contractual SLA, contact legal@overton.xyz.

7. Confidentiality

What you tell us about your business while we’re working together (roadmap conversations, support tickets that include sensitive details, sales calls) is confidential. We use it to support you and to improve the product, not to share with third parties or to brag about who our customers are without permission.

Material we publish or that anyone can derive from public use of the service isn’t confidential.

8. Intellectual property

We own the platform: the code, the design, the documentation, the trademarks. Using the service doesn’t transfer any of that to you.

You own your customer data, as described above. You also own anything you create that’s specific to your use of the service (brain configurations, ability customizations, exported reports).

If you give us feedback, we can use it to improve the service. We won’t claim it as our invention or attribute it to you publicly without permission.

9. Third-party services

The service integrates with third-party services you choose to connect, including Google (for sign-in and OAuth-scoped channels), Anthropic (the default AI model provider), Stripe (billing), and the public sources that abilities crawl. Your use of those services is also governed by their own terms.

We don’t control those services. If one of them changes their API, raises their prices, or goes down, we deal with it as best we can but can’t guarantee uninterrupted access through us.

10. Disclaimers

The service is provided “as is” and “as available.” Brains read from public and connected sources and summarize them; their summaries can be incomplete or wrong. You should treat brain output as a starting point for your own judgment, not as authoritative.

To the extent the law allows, we disclaim implied warranties of merchantability, fitness for a particular purpose, non-infringement, and quiet enjoyment.

11. Limitation of liability

To the extent the law allows, neither party is liable to the other for indirect, incidental, special, consequential, or punitive damages arising out of or relating to this agreement.

Each party’s total cumulative liability arising out of or relating to this agreement is capped at the fees you paid us in the twelve months immediately before the event giving rise to the claim. (Or, for free accounts, capped at $100.)

These limits don’t apply to fraud, willful misconduct, or anything else that’s non-waivable as a matter of law.

12. Indemnification

You’ll defend and indemnify us against third-party claims arising from your customer data being unlawful, your violation of section 3 (acceptable use), or your violation of someone else’s intellectual property rights.

We’ll defend and indemnify you against third-party claims that the service, used as we describe, infringes that third party’s intellectual property rights. If we believe the service may become subject to such a claim, we may modify it or, if we can’t reasonably do so, refund any prepaid unused fees and terminate the affected workspace.

13. Termination

You can cancel anytime through the workspace’s billing area. We can terminate for material breach (including non-payment) after notice and a reasonable opportunity to cure, or immediately if your conduct creates legal or operational risk to us or others.

On termination, your access ends, your brains are destroyed on the timeline in Privacy, and any prepaid unused fees are non-refundable except as required by law.

14. Changes to these terms

We may revise these terms. Material revisions get notified by email at least 30 days before they take effect, and the Updated date at the top of this page changes. Continued use of the service after a material change takes effect counts as acceptance.

Every revision lives in our public git repository as a commit; the diff is the audit trail.

15. Governing law

These terms are governed by the laws of the State of California, without regard to its conflict-of-laws principles. The parties consent to exclusive jurisdiction in the state and federal courts located in San Francisco County, California, except that either party may seek injunctive relief in any court of competent jurisdiction to protect its intellectual property or confidential information.
