    WireGuard keys are generated and kept on peers; device inventory, users, routes, groups, and access policies live in NetBird Cloud or the self-hosted management database, while payload traffic normally travels peer-to-peer and may traverse NetBird relay infrastructure when direct connectivity fails.
