Does Burna AI write patient data (PHI) to its logs?

No. By design, application logs carry record identifiers, organization identifiers and timestamps, not names, dates of birth or clinical text. The logger redacts known PHI fields and strips patient identifiers from request paths before a line is written, and automated checks during development flag code that would put patient details into a log, an error message or a test fixture. Access to PHI is recorded separately, in an audit log naming who acted, on which record, when and with what outcome, so operational logs never need to carry it.
