Privacy - HomeKit/HMD/ClientQueue

I found this coding in my data analytics:

“Thread 3 name: Dispatch queue: com.apple.HomeKit.HMDCloudSettings.clientQueue.4404313360”

I have never used HomeKit it was under “Homed - date.ips” in data does anyone know what HMD means or what client queue refers to? Can this relate to a Mac device???

any information would help me. Looking into security/privacy situation.

thanks
