1. Service Description

NotaryOS provides cryptographic receipt infrastructure for AI agents. The service generates tamper-evident, Ed25519-signed receipts that form per-agent hash chains, enabling verifiable audit trails for autonomous agent actions.

2. Acceptable Use

By using NotaryOS you agree not to:

• Abuse the service through automated flooding, denial-of-service attempts, or intentional circumvention of rate limits.
• Impersonate other agents or users by forging agent identifiers in receipt requests.
• Use receipts to fabricate false audit trails or manufacture fraudulent evidence of actions that did not occur.
• Reverse-engineer, decompile, or attempt to extract source code from the NotaryOS backend services.

3. API Keys

Each API key is non-transferable and tied to a single user account. You are responsible for safeguarding your key. NotaryOS reserves the right to revoke any key that is involved in abusive behavior, shared publicly, or used in violation of these terms.

4. Free Tier

The free tier includes up to 100 receipts per month per account. Free-tier usage is subject to fair-use policies. NotaryOS may throttle or suspend accounts that consistently exceed reasonable usage patterns on the free tier.

5. Paid Tiers

Paid subscriptions are billed monthly via Stripe. You may cancel at any time; cancellation takes effect at the end of the current billing period. No prorated refunds are issued for partial months. Pricing and tier limits are published on the pricing page.

6. Limitation of Liability

Receipts generated by NotaryOS are cryptographic records of data submissions. They attest that a specific payload hash was submitted at a specific time -- nothing more. NotaryOS is not liable for business decisions, disputes, or legal proceedings based on receipt data. The service is provided "as is" without warranties of any kind, express or implied.

7. SDK License

The NotaryOS SDK is licensed under the Business Source License 1.1 (BUSL-1.1). The license converts automatically to Apache 2.0 on February 25, 2029. Full license terms are included in the SDK repository.

8. Governing Law

These terms are governed by the laws of the State of Delaware, USA, without regard to conflict-of-law provisions. Any disputes arising under these terms shall be resolved in the courts of Delaware.
