This policy describes how Ephemeral Sentinel collects and uses information.
We may collect:
Collected information is used to:
Ephemeral Sentinel is designed to be privacy-first by architecture. The analysis pipeline never stores email body content, subject lines, sender or recipient addresses, attachment content, or raw URLs. Only metadata — verdict, score, signal identifiers, and timestamps — is retained, hashed where necessary, and subject to configurable retention limits.
Account and billing records are stored for the duration of your subscription. Analysis event metadata is retained according to the retention policy configured by your administrator and purged automatically when it expires.
Payment processing is handled by Stripe. Hosting infrastructure is provided by third-party cloud or on-premise providers selected by your organisation. No email content is shared with any third party.
Reasonable administrative and technical safeguards are applied to all stored data. PII-adjacent fields are hashed using HMAC-SHA256 with a per-tenant salt.
This policy may be updated periodically. Continued use of the service constitutes acceptance of the current policy.
