Wyze robot vacuum protection question

I read the following article about how malicious actors can use LiDAR to act as sounds waves and was curious what measures Wyze has implemented to prevent this? Are the maps the robot vacuums make stored AND encrypted at rest? Or are they stored in plaintext?

“Specifically, the LiDAR lasers they use to scan for objects can be captured and transformed into sound waves – turning the vacuums into roaming robot listening devices.
Using signal processing software and machine learning systems, computers can accurately pick out speech and musical patterns from things like television shows – even thought the vacuum doesn’t have a microphone on it.
Privacy experts have suggested that the maps made by vacuum bots, which are often stored in the cloud, pose potential privacy breaches that could give advertisers access to information about such things as home size – which suggests income level, and other lifestyle-related information.”
