Terms of Service

Brief is open-source software you install on your own machine. These terms set out the basic agreement between you and the Brief contributors when you install, use, or interact with the extension or the marketing site. We've kept them as short and plain as we can while still saying what needs to be said.

The short version

Use Brief however you like, within the law. Brief records your browsing activity to build a daily report and sends a summary of it to a language model to write that report. The software is free and provided as-is, with no warranty. We're not responsible for what the model says or for what you do with the output. If you can't agree to that, don't install the extension.

01Acceptance

By installing the Brief Chrome extension or using the site at brief.productivities.fyi, you agree to these Terms of Service and to the Privacy Policy. If you are using Brief on behalf of an organization, you represent that you have authority to bind that organization to these terms.

02The Brief software

The Brief extension is open source and distributed under the MIT License. A copy of the license ships with the source code. You receive whatever rights the MIT License grants you with respect to copying, modifying, and redistributing the software. These Terms of Service govern your use of the official builds we publish.

Updates

The Chrome Web Store may push extension updates automatically. We may modify, add, or remove features between versions. Major changes that affect data handling will be reflected in the Privacy Policy and surfaced in-app.

03Your account and the hosted service

On first use, the extension creates an anonymous account on the Brief backend so it can store your intervals and generated briefs. You may at any time sign in with Google to convert the anonymous account into a permanent one so it survives a reinstall. Brief is free; there is no paid tier and no payment processor.

Reasonable rate limits apply to uploads and brief generation to keep the service available for everyone. We may adjust those limits, or the feature set, on reasonable notice.

04Acceptable use

You agree not to use Brief, or the marketing site, to:

Violate any applicable law, regulation, or third-party right.
Attempt to disrupt, reverse-engineer for purposes other than those permitted by the MIT License, or interfere with the operation of the extension, the marketing site, the backend, or the model provider Brief connects to.
Abuse the hosted service — for example by circumventing rate limits or submitting fabricated activity at scale.
Resell or repackage Brief as a service without complying with the MIT License and removing any branding that would imply endorsement.

05Model output

The daily brief is generated by a third-party language model from your activity summary. It may be inaccurate, incomplete, or misleading. Treat it as a convenience read, not as an authoritative record of how you spent your time. Brief does not author the model output, does not pre-screen it, and cannot be held responsible for what a given model says on a given day.

06Third-party services

Using Brief involves several third-party services, each with its own terms:

Supabase hosts the Brief backend and authentication layer.
A language-model provider (currently DeepSeek) generates the prose brief; the specific provider may change over time and is disclosed in the extension and Privacy Policy.
Google provides the OAuth sign-in flow if you choose to attach an email.
Cloudflare hosts this marketing site.

We are not responsible for the availability, content, or behavior of any of these services, and your use of them is governed by their respective agreements.

07Intellectual property

The Brief name, wordmark, and visual identity belong to the Brief contributors. The source code is MIT-licensed. The marketing site's copy, layout, and images are © 2026 Brief contributors. Nothing in these terms grants you a trademark license; if you fork the source and ship a derivative product, please pick your own name.

08Disclaimer of warranties

The Brief extension, the marketing site, and any related services are provided "as is" and "as available," without warranty of any kind, express or implied, including but not limited to the implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that Brief will be uninterrupted, error-free, or that it will produce accurate, complete, or current results.

09Limitation of liability

To the maximum extent permitted by law, the Brief contributors are not liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of profits, revenue, data, or goodwill, arising from or in connection with your use of Brief — including model output or downtime of any third-party service. Because Brief is provided free of charge, our aggregate liability for any direct claim is limited to USD $50.

10Indemnification

You agree to indemnify and hold harmless the Brief contributors from any claim, demand, loss, or expense (including reasonable attorney's fees) arising out of your use of Brief in violation of these terms, any applicable law, or any third party's rights.

11Termination

You may stop using Brief at any time by uninstalling the extension or removing your saved data through your browser's controls. We may discontinue the extension, the marketing site, or any feature at any time, with or without notice. Provisions that should reasonably survive termination — license, intellectual property, disclaimers, limitations of liability, indemnification — will do so.

12Governing law

These terms are governed by the laws of the jurisdiction in which the Brief contributors reside, without regard to its conflict-of-laws rules. Disputes that cannot be resolved informally will be brought in the competent courts of that jurisdiction, except where mandatory consumer-protection law in your country of residence provides otherwise.

13Changes to these terms

We may update these terms from time to time. When we do, we'll change the "Effective" date at the top of this page and, for material changes, surface a notice in the extension before they take effect. Continued use of Brief after the new effective date constitutes acceptance of the revised terms.
