Acceptable Use Policy

This Acceptable Use Policy (AUP) sets out the conduct we require of everyone who uses Herald. It applies in addition to the Terms & Conditions. Violations may result in immediate suspension.

Scope

This policy applies to every account, product, and integration connected to the Herald service, including use of the Herald SDKs, public API, webhooks, and email ingestion. By using Herald you agree to this policy. It incorporates by reference the Terms & Conditions and the Privacy Policy.

Prohibited uses

You must not use Herald to:

Enforcement

We may suspend or terminate any account that violates this policy, with as much notice as the circumstances allow. For clear violations — CSAM, active security attacks, fraud — suspension may be immediate and without prior notice. For ambiguous situations, we will contact the account owner before acting where possible. Repeated or egregious violations result in permanent termination with no refund of prepaid fees.

We will cooperate with law enforcement when required by law and will preserve relevant data for a commercially reasonable period if we receive a valid legal hold.

Responsible disclosure

If you discover a security vulnerability in Herald, report it to security@withherald.co before disclosing it publicly. We will acknowledge receipt within one business day and work to resolve the issue promptly. Good-faith security research conducted within these bounds is not a violation of this policy. See withherald.co/security for our security posture and contact details.
