We operate with restraint, provenance, and auditability. If something is not necessary, we do not collect it.

Effective date: October 5, 2025. This Notice supersedes prior versions.

Cookies & Similar Technologies

We use strictly necessary cookies for core functionality (session continuity, security) and, with consent, analytics cookies for aggregate insights. You can manage preferences through your browser and any consent banner we present. Blocking essential cookies may degrade Site functionality; we do not gate access behind analytics consent.

We share Personal Data with vetted service providers under contract (hosting, security, analytics, email), limited to the minimum necessary to deliver the service, with confidentiality and processing restrictions. We may disclose data if required by law or to protect rights, safety, or integrity. We do not sell Personal Data.

Retention

We retain Personal Data only as long as necessary for the purposes described, to comply with legal obligations, or to resolve disputes. Typical ranges: contact correspondence — months; candidate files — one hiring cycle plus a limited archival period (unless you request deletion); security logs — short, rolling windows unless an incident is under investigation.

Security

We employ layered controls: encryption in transit, access control by role, least-privilege keys, logging and anomaly detection, and separation of environments. No system is impenetrable; responsible disclosure is welcomed at[email protected]with a minimal reproduction path. Do not publicly disclose before coordination.
