HKBU Mobile App Backend (gated)
Backend host serving the official HKBU Mobile application (mapp-api.hkbu.edu.hk). The host resolves over TLS 1.3 with HSTS and serves app support content such as the app privacy notice (HTTP 200), but there is no public developer documentation, no OpenAPI and no self-service signup; the API is intended for the first-party mobile client only. Listed for completeness — no endpoints are documented or independently verified.
