Trust documents in one place.

Program
Four places to look
Trust at Keisan is split into four plain surfaces: security controls, privacy commitments, service status and legal documents.
Security
How sessions, account-scoped data, keys and API boundaries are protected.
Privacy and data rights
What we collect and why, how long we keep it, and how to export or delete it.
Service status
The parts of Keisan, from the web app to client approvals, and how to report a problem.
Legal documents
Terms, the data processing addendum, acceptable use, cookies and sub-processors.
Posture
How your data is handled today
These describe how Keisan works now. If your procurement process needs more, write to us through the contact page.
Access
Scoped to your account
Projects, estimates, rate cards and proposals belong to the account that made them. Database policies return only that account's rows.
Your content
Never used for training
Your briefs, estimates, rate cards and proposals are encrypted at rest and never used to train models, sold or shared with other users.
Data rights
Your data, your call
Export your data as a file or delete it from settings. Deleting removes your projects, estimates, rate cards and settings.
