The agent is cross compiled for both Intel and Apple Silicon (Arm-based) architectures.
All agent specific data is aged out and deleted after 30 days. Only non-identifiable metrics and aggregate data is used longer term to improve the service.
Agents can only talk outbound (push) from your machine. There is no inbound communication possible and no remote access tooling or functionality. There are no listening ports on the agent. It only talks outbound via DNS and HTTPS TCP 443 to write data to (not read data from) buckets.
