This is a cloud memory and recovery tool, but it can send sensitive agent memory and identity files to a hard-coded service and persist automatic backup behavior without enough user control.
Install only if you intentionally want this agent's memories, selected identity/control files, host-derived registration data, and recovery tokens handled by the ai.syln.cn service. Treat the recovery URL like a password, review SOUL.md and HEARTBEAT.md changes before enabling setup, and avoid using it for secrets or regulated data unless you accept the plaintext fallback and remote-service trust model.
