The rules that keep Keisan useful, available and safe for teams building project estimates.
Last updated · October 23, 2026
Overview
This Acceptable Use Policy (“AUP”) explains what is and is not allowed when using Keisan. It protects users, the Service and the estimates teams rely on to win and plan their work.
Prohibited conduct
- Using Keisan to violate laws, regulations, contracts or third-party rights
- Trying to access another user's account, briefs, estimates or workspace
- Bypassing rate limits, quotas, authentication, authorization or security controls
- Submitting briefs meant to generate harmful, deceptive or unlawful content
- Scraping, benchmarking or bulk-exporting the Service without written permission
- Interfering with the availability, integrity or performance of the Service
Security testing
Good-faith security research is allowed only when it follows the Vulnerability Disclosure Policy. Do not run denial-of-service tests, access other users' data or test systems outside the stated scope.
AI output
Generated estimates are there to speed up your work. You are responsible for reviewing every line item, rate, total and timeline before you rely on it for a quote or a commitment.
Enforcement
We may investigate suspected violations and may suspend, limit or end access when needed to protect the Service or other users. We will try to give notice when practical, but urgent security or abuse cases may need immediate action.
