Is Gloom Dark Mode safe?

Low risk

Gloom Dark Mode sends a persistent locally stored UUID to Google Analytics at startup and every hour.

Gloom Dark Mode creates and stores a UUID in browser local storage for analytics tracking. It sends that identifier to Google Analytics when the background script starts and repeats the same run event every 60 minutes.
