Is CMG Hacks safe?

Low risk

CMG Hacks sets a Coolmathgames premium-play cookie and modifies Coolmathgames game pages to skip ad UI.

When the extension runs, its background worker writes a Coolmathgames cookie named cmg_premium_play with the value true. On matching Coolmathgames game pages, its content script adds skip-ad and fullscreen controls, watches for the ad blocker overlay, and invokes the page's ad-removal function when available.
