Is Auto Refresh Plus | Page Monitor safe?

It lets you set predefined, custom, random, scheduled, or limited refresh intervals, including hard refreshes and behavior changes based on user interaction. It can monitor pages for keywords or content changes, highlight or scroll to detected keywords, click detected elements, and send alerts through push notifications, email, or webhooks. It also includes options for custom scripts, generated scripts or expressions, settings sync, profiles, and multi-device settings.
