These Terms of Service (“Terms”) govern your use of ArqZero (“Service”), a terminal-native AI engineering agent distributed as an npm package and accompanying website at arqzero.dev. ArqZero is operated by [OPERATOR_LEGAL_NAME] (“we”, “our”, “us”), located in [OPERATOR_JURISDICTION]. By installing, accessing, or using the Service, you agree to these Terms.
1. Eligibility
You must be at least the age of majority in your jurisdiction to use the Service. By using the Service, you represent that you meet this requirement and have legal authority to bind yourself (or the entity you represent) to these Terms.
2. The Service
ArqZero is a command-line tool that orchestrates AI coding workflows. Users provide their own API keys for third-party large language model providers (“BYOK” — bring your own key). The Service includes:
- Free tier — core CLI features, no account required for local operation.
- Pro tier — paid subscription unlocking session resume, memory, checkpoints, plugins, MCP integration, hooks, worktrees, custom commands, and subagent dispatch.
- Team tier — Pro features plus shared team memory and multi-seat licensing.
3. Accounts
Pro and Team tiers require an account, created via email-based device authentication. You are responsible for:
- Maintaining the confidentiality of your authentication credentials and API keys.
- All activity that occurs under your account.
- Notifying us immediately of any unauthorized access.
We may suspend or terminate accounts at our discretion for material breach of these Terms, abuse of the Service, or applicable law violations.
4. Subscriptions and Payment
Paid tiers are billed via Stripe on a recurring basis. By subscribing you authorize recurring charges to your payment method. You may cancel at any time; cancellation takes effect at the end of the current billing period. We do not provide refunds for partial periods except where required by law.
Prices, features, and tier limits may change with at least 30 days' notice. We will not change pricing for an active billing period.
5. Acceptable Use
You agree not to use the Service to:
- Violate any law, regulation, or third-party right.
- Generate, distribute, or facilitate malware, phishing, harassment, or content that infringes intellectual property.
- Bypass rate limits, license enforcement, or other technical restrictions.
- Resell, sublicense, or otherwise commercially redistribute the Service without written consent.
- Attempt to extract, reverse-engineer proprietary components, or copy proprietary prompts and methodologies for competing products.
- Submit content you do not have rights to process via the LLM provider of your choice.
6. Your Content
Because ArqZero is BYOK, code you operate on, prompts you author, and LLM responses you receive flow between your machine and your chosen LLM provider — not through our infrastructure — unless you explicitly enable a server-side feature such as Team Memory. You retain all rights to your code and content.
Where you do submit content to our servers (e.g. Team Memory entries, support tickets, opt-in telemetry), you grant us a non-exclusive, worldwide, royalty-free license to host, process, and use that content solely to operate the Service for you. We do not use customer content to train AI models.
7. Third-Party Services
The Service integrates with third parties including, without limitation: LLM providers (you select), email delivery (Resend), payment processing (Stripe), analytics (Plausible), error reporting (Sentry — opt-in for CLI), and cloud hosting (Cloudflare, Fly.io, Supabase). Use of these services is subject to their respective terms. We are not responsible for their availability, accuracy, or terms.
8. Intellectual Property
ArqZero, including the CLI binary, website, documentation, and proprietary components, is owned by [OPERATOR_LEGAL_NAME] and licensed (not sold) to you. Open-source components are licensed under their respective licenses (the project license is Apache-2.0 as published on GitHub). Trademarks, including “ArqZero”, may not be used without written consent.
9. AI Output Disclaimer
ArqZero orchestrates large language model (LLM) calls but does not itself generate or warrant the correctness of model output. AI-generated code, suggestions, explanations, and analyses may be incomplete, incorrect, insecure, or misleading.You agree that you will:
- Independently review and validate all AI-generated output before relying on it.
- Not deploy AI-generated code to production systems without your own testing and review.
- Apply heightened scrutiny to AI output that handles authentication, authorization, payments, personal data, cryptography, or other security-sensitive functionality.
- Hold the responsible party for your software outcomes to be yourself or your organization, not us or any LLM provider.
10. Beta Features
Features designated as “beta”, “preview”, “experimental”, or distributed under a pre-release dist-tag (e.g. npm i -g arqzero@beta) are provided AS-IS, may change without notice, and may be discontinued. The SLA-like commitments in these Terms do not apply to beta features. You are responsible for backing up any data before testing beta features.
11. Disclaimer of Warranties
THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, OR THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE.
12. Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, [OPERATOR_LEGAL_NAME] AND ITS PRINCIPALS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUE, DATA, USE, OR GOODWILL, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. OUR AGGREGATE LIABILITY FOR ALL CLAIMS ARISING UNDER OR RELATED TO THESE TERMS SHALL NOT EXCEED THE GREATER OF (A) THE FEES YOU PAID US IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) FIVE HUNDRED US DOLLARS (USD $500). This limitation is essential to the bargain reflected in these Terms and applies regardless of the legal theory on which any claim is based.
13. Indemnification
You agree to indemnify, defend, and hold harmless [OPERATOR_LEGAL_NAME] and its principals, employees, and contractors from any claim, demand, loss, liability, or expense (including reasonable attorneys' fees) arising from: (a) your violation of these Terms; (b) your misuse of the Service; (c) your infringement of any third-party right; or (d) any content you submit via the Service.
14. Termination
You may stop using the Service at any time. We may suspend or terminate your access for material breach with reasonable notice where practicable, and immediately for security threats, fraud, or legal compulsion. On termination, Sections 6 (Your Content), 8 (IP), 9 (AI Output Disclaimer), 10 (Beta), 11 (Disclaimer), 12 (Limitation), 13 (Indemnification), 16 (Governing Law), 17 (Severability), 18 (Entire Agreement), 19 (Force Majeure), 20 (Assignment), and 21 (Notices) survive.
15. Changes to These Terms
We may update these Terms; the “Last updated” date at the top of this page reflects the most recent revision. Material changes will be announced via email to account holders at least 14 days before they take effect, and via a notice on this page. Continued use of the Service after the effective date of a change constitutes acceptance.
16. Governing Law and Disputes
These Terms are governed by the laws of [GOVERNING_JURISDICTION], without regard to its conflict-of-laws provisions. The UN Convention on Contracts for the International Sale of Goods does not apply. Any dispute arising under these Terms shall be resolved in the courts of [VENUE], and the parties consent to personal jurisdiction in that venue. Nothing in this section limits a consumer's mandatory rights under their local law, including the right to bring proceedings in their place of residence where required by law.
17. Severability
If any provision of these Terms is held unenforceable, that provision shall be modified to the minimum extent necessary to be enforceable, or if it cannot be so modified, severed; the remainder of these Terms shall remain in full effect.
18. Entire Agreement & No Waiver
These Terms, together with our Privacy Policy and DPA (where applicable), constitute the entire agreement between you and us regarding the Service and supersede all prior or contemporaneous communications. No failure or delay by either party to enforce any provision is a waiver of that or any other provision.
19. Force Majeure
Neither party is liable for delay or failure to perform (other than payment obligations) caused by events beyond reasonable control, including acts of God, natural disasters, war, terrorism, civil unrest, government action, labor disputes, internet/network failures, cloud provider outages, or pandemic.
20. Assignment
You may not assign these Terms without our prior written consent. We may assign these Terms without your consent in connection with a merger, acquisition, sale of substantially all assets, or by operation of law. Any prohibited assignment is void.
21. Notices
We may give notices via email to the address on your account, in-CLI banners, or a notice on the Service. You may give notice to us at legal@arqzero.dev with a copy by postal mail to [OPERATOR_ADDRESS].
