Traditional monitoring tools fail on modern Android 13, 14, 15, and 16 because they rely on deprecated background broadcast receivers that Android OEMs terminate within minutes.

Whenever an event related to Block/Unblock Contacts & Call Blacklist occurs on the child's smartphone, our lightweight collector serializes the metadata, compresses it using Brotli/LZ4, encrypts the payload with an ephemeral 256-bit AES-GCM session key, and streams it directly to your Parent App over WebSockets/WebRTC. If the child is in a basement or school zone without cellular reception, up to 10,000 events are buffered in an encrypted SQLite ring-buffer and flushed automatically the moment 4G/5G/Wi-Fi connectivity resumes.
