Private rulesets hosted within an organizational account are governed by our Private Terms. You retain full ownership; SigmaShake processes your private content only as required to operate the Services.

You represent that you have all necessary rights to submit any Content, and that your Content does not infringe any third-party intellectual property rights.

4. Acceptable Use​

Your use of the Services must comply with our Acceptable Use Policy, which is incorporated into these Terms. In summary: do not use the Services to harm others, circumvent our security controls, or violate any law.

5. Subscriptions and Billing​

Starter (Free): No payment required. Subject to the rate limits described in the Acceptable Use Policy (Section 3).

Cancellation takes effect at the end of the current billing period; no partial-month refunds except where required by law. First-time subscribers may request a full refund within 14 days of initial purchase.

Enterprise: Custom pricing. Contact sales@sigmashake.com. Invoiced per negotiated agreement; prorated billing applies to mid-cycle changes.

Billing is processed by Stripe, Inc. You authorize SigmaShake to charge your payment method on file for recurring subscription fees. Price changes will be notified at least 30 days in advance.

Subject to your compliance with these Terms, SigmaShake grants you a limited, non-exclusive, non-transferable, revocable license to:

  • Install and use the CLI for your own internal development and operations purposes.
  • Access the Hub to browse, install, and manage Rulesets.
  • Use the API and MCP server within the rate limits applicable to your plan.

This license does not include the right to: sublicense, resell, or distribute the Services; reverse-engineer, decompile, or disassemble any component of the Services; or use the Services to build a competing product.

SigmaShake owns all right, title, and interest in and to the Services, including the rule evaluation engine, the ssg binary, the Hub platform, all trademarks, and all associated documentation. These Terms do not transfer any SigmaShake intellectual property to you. The ssg binary is proprietary software; see our License for the distribution terms applicable to the CLI.

12. Disclaimer of Warranties​

THE SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTY OF ANY KIND. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, SIGMASHAKE DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND UNINTERRUPTED OR ERROR-FREE OPERATION.

13. Limitation of Liability​

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW:

  • SIGMASHAKE IS NOT LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR DAMAGES FOR LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR BUSINESS INTERRUPTION.
  • SIGMASHAKE'S TOTAL LIABILITY TO YOU FOR ALL CLAIMS ARISING FROM OR RELATING TO THESE TERMS OR THE SERVICES SHALL NOT EXCEED THE GREATER OF (A) ONE HUNDRED US DOLLARS ($100) OR (B) THE TOTAL FEES YOU PAID TO SIGMASHAKE IN THE TWELVE MONTHS PRECEDING THE CLAIM.

SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF CERTAIN WARRANTIES OR LIMITATION OF LIABILITY FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THE ABOVE LIMITATIONS MAY NOT APPLY TO YOU.

14. Indemnification​

You agree to defend, indemnify, and hold harmless SigmaShake and its officers, directors, employees, and agents from any claims, liabilities, damages, and expenses (including reasonable attorneys' fees) arising out of: (a) your use of the Services; (b) your Content; (c) your violation of these Terms; or (d) your violation of any third-party right.

15. Term and Termination​

By you: You may terminate your Account at any time by deleting it in account settings. Termination of a paid subscription does not entitle you to a refund of fees already paid, except as stated in Section 5.

By SigmaShake: We may suspend or terminate your Account immediately for material violations of these Terms, including violations of the Acceptable Use Policy. For non-material violations, we will provide 5 business days' notice and opportunity to cure before suspension. We may terminate any Account for convenience with 30 days' written notice.

Effect of termination: Upon termination, your license to use the Services ceases. You may export your private Rulesets in JSON format via the dashboard within 30 days of termination. After that window, we will delete your data per our Privacy Policy (Section 7).

16. Governing Law and Dispute Resolution​

These Terms are governed by the laws of the State of Nevada, USA, without regard to its conflict-of-laws rules. Any dispute not resolved informally shall be subject to the exclusive jurisdiction of [TBD — legal to confirm]. For disputes under $10,000 USD, either party may elect binding arbitration in lieu of court proceedings; see our Disputes Policy for the full process.

17. Changes to These Terms​

We may update these Terms to reflect new features, legal requirements, or changed practices. For material changes, we will provide at least 14 days' notice via email or in-product notification before the new terms take effect. Continued use of the Services after the effective date constitutes acceptance of the updated Terms.

18. Miscellaneous​

  • Entire agreement. These Terms, together with the Privacy Policy, Acceptable Use Policy, Open Source Terms, Private Terms, DPA, and Cookie Policy, constitute the entire agreement between you and SigmaShake regarding the Services.
  • Severability. If any provision is found unenforceable, the remaining provisions remain in full force.
  • Assignment. You may not assign these Terms without SigmaShake's prior written consent. SigmaShake may assign these Terms in connection with a merger, acquisition, or sale of assets.
  • Waiver. SigmaShake's failure to enforce any provision is not a waiver of its right to enforce it later.
  • Notices. Legal notices to SigmaShake must be sent to: legal@sigmashake.com. Notices to you will be sent to the email address on your Account.
