Is Screenly : Screenshot & Screen Video Recorder safe?

This extension records screen video and captures screenshots from tabs, desktop, camera, or selected areas.

It lets you record your desktop, current tab, or camera, with options to include microphone audio, webcam video, video dimensions, and drawing tools during tab recording. It also captures full-page, visible-area, selected-area, screen, or application-window screenshots, supports delayed capture, and includes screenshot editing and download options. Recordings can be saved to local disk or to an online account, and uploaded videos can be downloaded in WebM format.
