Top Risks

• Privacy policy is Google's generic policy (scope_extension=false, admits data collection and third-party sharing) — scores maximum privacy risk.
• Uninstall URL hijack redirects to excalidraw.com shared room — suspicious for a tab manager, warrants investigation.
• new Function() constructor in bundled JS executes dynamic string code against window — code execution risk.
• Developer uses free Gmail with no business domain; no verified publisher badge; low accountability.
• history permission exposes full browsing history; combined with tabs gives broad user profiling capability.
