For IT
Know what runs on your box.
Classline is a small Go application with Postgres, field-level encryption, and no analytics or third-party scripts.
Operationally legible
Deploy it behind your own TLS terminator. Keep your own keys. Inspect the source. The application does not need a vendor database to function.
Encryption with boundaries
Student identity fields are encrypted at rest. Participant message bodies use browser-side end-to-end encryption, with controlled safeguarding access through enrolled devices and an audit log.
