Designed so Primust cannot see what you are governing.

The data boundary is part of the product design. Signing requests contain commitment hashes and execution metadata, not the underlying content being governed.

§ 01Boundary

Designed so Primust does not need to see what you are governing.

What leaves your environment
Commitment hashes for the governed input, output, or artifact.
Identifiers for the declared checks, policies, or bundles that ran.
Execution metadata such as timestamps, environment labels, run IDs, and proof level.
Declared gaps when a required check did not run or produced incomplete evidence.
What stays with you
Prompts, source content, uploaded documents, model outputs, or code diffs do not need to leave your environment.
Primust does not need your raw governed data in order to issue a credential.
Verification can be done later from the credential, the public key, and the verifier.
§ 02Operations

Store only the information needed to run the service and verify the credential.

Trust Boundary
Account and service metadata

Primust stores standard account information, authentication state, billing records, and service telemetry needed to operate the dashboard and API. That is separate from governed content.

Trust Boundary
Signing metadata

Signing requests contain commitment hashes and related execution metadata. By default, signing metadata is retained for 90 days for service operation, abuse prevention, and support.

Trust Boundary
Open verification

A relying party can verify issuer, signature, proof level, bundles, and declared gaps with the open-source verifier and Primust public keys. Verification does not require calling Primust.

Trust Boundary
Key distribution

Public verification keys are published through the Primust well-known key endpoint. That lets counterparties validate a credential independently and archive the trust material they rely on.

§ 03Disclosure

Marketing analytics are limited to the public site and are not part of the proof path.

Public website

The marketing site uses Vercel Analytics and Vercel Speed Insights to measure page traffic and page performance. Those scripts are limited to the public website. They are not part of the dashboard, API, signing flow, or offline verification flow.

Product proof and website analytics are separate systems.

Primust does not use business-visitor identification on the marketing site, and the verifier does not depend on Primust analytics infrastructure.

Read The Boundary

Start with the verifier and the policy docs, not marketing promises.

The strongest trust claim on the site should be one you can test yourself.
