Extension Details

Developer: dadan.io

Rating: 4.7 ★ (52 ratings)

Users: 4,000

Context-Aware Verdict

CRITICAL

Overall Risk

Trust Factors: The extension has a decent rating of 4.7 stars from 52 reviews and serves a legitimate purpose as a screen recording and annotation tool. However, the relatively small user base of 4,000 users and limited developer information raise some concerns about the extension's maturity and transparency.

Concerns: The extension's permission set is extremely broad and concerning for its stated purpose. While screen recording tools do need some elevated permissions, this extension requests access to cookies, all websites, download capabilities, and tab manipulation - far beyond what's necessary for basic screen recording. The ability to inject content scripts into all URLs means it can read and modify any webpage you visit. The unsafe WebAssembly execution policy is particularly troubling as it could hide malicious code. The combination of broad host permissions with cookie access creates significant privacy and security risks, as the extension could potentially track your browsing habits and steal sensitive information across all websites.

Recommendations: Given the critical risk level, avoid installing this extension on your main browser profile. If you must use it, create a dedicated Chrome profile with minimal sensitive data and only use it when actively recording screens. Consider alternative screen recording tools with more limited permissions, such as built-in browser recording features or desktop applications that don't require such extensive web access.
