Terms of Service

What you're agreeing to.

These Terms of Service govern your use of Precursor — the macOS application, theprecursor.build website, and related services (together, the "Service"), operated by the Precursor team ("we", "us").

By creating an account or using the Service, you agree to these terms and to ourPrivacy Policy. If you do not agree, do not use the Service. If you are using Precursor on behalf of an organization, you confirm you have authority to bind that organization to these terms.

Precursor is offered as a public beta. Features may change, break, or be removed, and availability is not guaranteed.

One account, yours to keep secure.

• You must be at least 18 years old and legally able to enter into these Terms where you live.
• You may sign in using Google, GitHub, or a magic link sent to your verified email address. Precursor does not offer password-based sign-in.
• You are responsible for keeping your email account and your device secure, and for all activity under your account.
• Provide accurate information, and keep your email address current so we can reach you.
• Tell us promptly at hello@precursor.build if you believe your account has been compromised.

The graph is yours, and it stays on your machine.

Your conversations, projects, drafts, provider runs, files, and related workspace data are stored locally on your device. Precursor does not upload, host, synchronize, or back up that content through the Precursor cloud service.

You retain ownership of your local content. When you use an AI agent, the desktop application may provide selected local context directly to the provider tooling you choose. That processing is governed by your agreement with the provider.

You are responsible for maintaining backups of local content you cannot afford to lose.

We do not use your content to train, fine-tune, or develop AI or machine learning models.

Your agents, your subscription, your review.

Precursor coordinates AI coding agents that you run under your own provider accounts and subscriptions. Your use of those agents is governed by your agreement with each provider, and their fees are yours to pay.

AI output can be wrong, incomplete, insecure, or infringing. Precursor makes the reasoning behind it traceable; it does not make it correct. You are responsible for reviewing, testing, and deciding whether to ship anything an agent produces, and you should never rely on it without human review in a production or safety-relevant context.

What you may not do.

• Break the law, infringe anyone's intellectual property, or violate anyone's privacy.
• Build or operate malware, spyware, credential-harvesting tools, or anything designed to cause damage or gain unauthorized access to systems.
• Probe, scan, overload, or interfere with the Service or its infrastructure, or bypass any access limit, rate limit, or security control.
• Reverse engineer, decompile, or resell the Service, or use it to build a competing product.
• Send us — through feedback, support, or any other channel — content you do not have the rights to, or personal data you are not permitted to share.
• Share your account access or let others use your account.

We may suspend or terminate access for a violation of these rules, and where the violation is serious or ongoing we may do so without prior notice.

What stays ours.

The Service — its software, design, documentation, and the Precursor name and marks — is owned by us and protected by intellectual property law. We grant you a limited, revocable, non-transferable license to use the Service in line with these terms. Nothing here transfers any of our rights to you.

Feedback you send us is welcome and we may use it without obligation or compensation to you.

How this ends.

You may stop using Precursor and delete your account at any time, as described in thePrivacy Policy. We may suspend or discontinue the Service, or any part of it, with reasonable notice where practical.

Material changes to these Terms may require you to accept a new version before continuing to use authenticated features.

Deleting your Precursor account revokes your cloud sessions and begins a seven-day recovery period. After that period, cloud account data is deleted subject to limited legal and security retention. Deleting your account does not remotely delete local content from your devices; the application provides separate export and local deletion controls.

On termination, your license to use the Service ends. Sections that by their nature should survive — ownership, disclaimers, and limitation of liability — do.

Provided as is.

To the fullest extent permitted by law, the Service is provided "as is" and "as available", without warranties of any kind, whether express, implied, or statutory — including any implied warranty of merchantability, fitness for a particular purpose, non-infringement, or accuracy. We do not warrant that the Service will be uninterrupted, secure, error-free, or that any output will meet your requirements. Some jurisdictions do not allow certain exclusions, in which case they do not apply to you.

Limits.

To the fullest extent permitted by law, we are not liable for indirect, incidental, special, consequential, or punitive damages, or for lost profits, lost revenue, lost data, or business interruption, arising out of or relating to your use of the Service — even if we were advised such damages were possible.

Our total liability for any claim relating to the Service is limited to the greater of the amounts you paid us in the twelve months before the claim, or one hundred US dollars (US$100). Nothing in these terms limits liability that cannot be limited by law.

You agree to indemnify and hold us harmless from claims, losses, and expenses arising from your content, your use of the Service, or your breach of these terms.

The remainder.

These terms and the Privacy Policy are the entire agreement between us about the Service. If a provision is found unenforceable, the rest stays in force. Our failure to enforce a provision is not a waiver of it. You may not assign these terms without our consent; we may assign them in connection with a merger, acquisition, or sale of assets.
