No, but after you setup Lansweeper server and link it Cloud, your agents if not able to contact your server directly, will switch to contact Cloud, making it theoretically 'cloud only', with extra steps..
Link your Lansweeper with Cloud.
Install LsAgent on laptop, including server and agentkey in it.
LsAgent will try to connect to your local server and if not available will switch to Cloud and report every 60 minutes (lowest time window)
The following may be visible in log during installation and linkage to cloud
