Acceptable Use Policy

The rules that keep Keisan useful, available and safe for teams building project estimates.

Last updated · October 23, 2026

01

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.

02

Authorized use only

Use Keisan to estimate projects you own, run or are authorized to work on. Do not submit briefs describing work you have no lawful basis to estimate, and do not use estimates in ways that violate the rights of others.

03

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
04

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.

05

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.

06

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.

07
