Our servers don’t store data, they are used as a connection point.
To be able to connect to Lima, you are asked to create an account during installation, with a username and a password. This user name enables your account and your devices (your Lima included) to be recognized in the network when you are not home. Kind of like the way a DNS server links a domain to an IP address.
This information is the only one that we need to be on our server so you can use your Lima, and it is necessary only when you add a new device to your account.
