Privacy Policy

What we collect

• Account information: the email address and credentials you register with.
• Ledger records: every movement on the rail is recorded on the ledger. This includes credit purchases, toll lines, quota key issuance, and metered spend. Ledger records are the product; they are retained as the settlement history of the rail.
• Usage data: quota keys are metered to the second. Metering records are part of the ledger.
• Technical data: standard server logs (IP address, timestamps, request paths) used to operate and secure the service.

What we do with it

• Operate the rail: settle movements, meter spend, issue receipts, and enforce grade labels.
• Secure the rail: detect abuse, fraud, and violations of the acceptable use policy.
• Communicate with you about your account and about material changes to our terms.
• Comply with law where required.

What we do not do

• We do not sell your personal data.
• We do not share your personal data with advertisers.
• We do not use your prompts, workloads, or agent activity to train models.

Ledger transparency

The rail settles on one ledger, and ledger lines carry grades (live, live-attested, attested, fixture-mechanism, fixture). Receipts and attestations are designed to be verifiable. Public proof artifacts are limited to ledger lines and attestations; they are not published with your account identity attached.

Retention

Ledger records are retained for the life of the rail because they are the settlement history. Account information is retained while your account is active and for a reasonable period after closure, as required for legal, tax, and audit purposes. Server logs are rotated on a regular schedule.

Security

We apply reasonable technical and organizational measures to protect account data and ledger integrity. No system is perfectly secure; see risk disclosures.

Your choices

You may export your records from the account dashboard and may request account closure through contact. Closing an account does not erase settled ledger lines, which are the shared settlement record of the rail.

Changes

Material changes to this policy are posted on this page with a revised date.

Governing law

This policy is governed by the laws of the State of Texas.
