The deal between you and Yelt.

These terms govern your use of Yelt (“Yelt”, “we”, “our”) — a policy engine and tamper-evident audit ledger for AI agents that touch money. By creating an account or using the service, you agree to them. If anything below is unclear, email legal@yelt.ai and we'll explain it.

What Yelt does

Yelt sits between AI agent runtimes (Claude Code, Cursor, Codex, custom agents) and the financial systems they touch (Stripe, Mercury, Brex, on-chain wallets, ERPs). You write policies in plain English. Yelt compiles them to a typed runtime descriptor. Every agent action is evaluated against active policies; the decision plus its evidence chain lands in an append-only ledger.

What Yelt does not do:

• We don't run agents. You bring your own agent runtime; we govern what it does.
• We don't move money. Stripe, Mercury, your wallets, your ERPs — those are yours. We sit in front of them.
• We don't hold customer financial data we don't need. The policy gateway sees tool-call payloads in flight; the control plane stores only the redacted audit metadata.
• We're not a money transmitter, not an exchange, not a broker-dealer. We're a software application.

Your account

• You must be at least 18 and authorized to bind the business you're using Yelt for.
• You're responsible for keeping your credentials secure. We use Supabase Auth (magic link + Google/GitHub OAuth) — no passwords to lose.
• Each org has at least one admin. If you lose admin access, email support@yelt.ai.

Acceptable use

You agree not to use Yelt to:

• run agents that intentionally bypass legitimate financial controls (sanctions screening, KYC, AML);
• launder proceeds of crime or evade tax reporting in your jurisdiction;
• impersonate another organization, individual, or financial institution;
• upload material that infringes third-party IP, contains malware, or violates someone's privacy;
• scrape, reverse-engineer, or attempt to extract our policy IR, gateway internals, or hash-chain implementation at scale.

We reserve the right to suspend accounts that breach this clause — usually with notice; without notice when the breach is ongoing and clear. We'll always preserve your data export rights described in the Privacy policy.

Payments — how money flows

Yelt's subscription billing. Stripe is our billing rail. The Developer tier ($30/dev/month) and Company tier ($1,500/month) are subscription products. The Enterprise tier is a custom contract; talk to hello@yelt.ai.

Annual contracts. 20% discount versus monthly. Renewals are explicit and never auto-extended.

Refunds. Within 14 days of first paying for a tier we refund unused time, no questions. After that we don't — you've had a long enough trial to know.

Liability + risk

Yelt is provided as-is. The policy engine evaluates agent actions deterministically; the audit ledger's integrity is cryptographically verifiable. We do not guarantee that every agent action is safe, only that every action is governed by the policy you authored and recorded with tamper-evident proof.

To the maximum extent permitted by law: we're not liable for indirect, incidental, special, or consequential damages — including lost revenue, lost profits, or business interruption. Our aggregate liability for any claim is capped at the greater of $100 USD or the fees you paid Yelt in the 12 months preceding the claim.

Some agent actions are irreversible (on-chain transactions, sent emails, posted GL entries). Yelt's policy engine can prevent or hold them; once executed downstream, Yelt cannot reverse them.

Intellectual property

You own your data. You grant us a limited license to process it for the purpose of providing the service (evaluating policies, recording audit events, generating digests). The service itself — code, design, policy IR specification, hash-chain implementation, agent skills format — remains ours, except where explicitly open-sourced.

Termination

You can cancel anytime from the Billing tab. Your data export rights persist for 30 days after cancellation; after that, hard delete cascades through every row that doesn't belong to the audit ledger. The audit ledger itself is retained per the retention rules of your tier (30 days Developer, 1 year Company, 7 years Enterprise) before purging.

We can terminate accounts for repeated breach of acceptable use, payment failure (after 14 days of grace), or operational necessity (rare — would be communicated 60 days ahead).

Changes to these terms

We'll update the “Last updated” date and email active orgs at least 14 days before material changes take effect. Continued use after the effective date constitutes acceptance.

Governing law + disputes

These terms are governed by the laws of the State of Delaware, United States, without regard to conflict-of-laws principles. Disputes go to the state and federal courts located in Wilmington, Delaware as the venue, except that you may always bring small-claims actions in your local jurisdiction. Both parties waive jury trial where applicable.
