Analytics Percentage Highlighter
Version 1.1 View in Chrome Web Store
Extension Details
Context-Aware Verdict
The extension has a perfect 5.0 rating, though this is based on only 2 reviews which limits reliability. With 429 users, it has a relatively small user base. The developer website (beamusup.com) provides some transparency, though limited developer information is available. The extension targets a specific, legitimate use case for Google Analytics users.
The primary concern is the storage permission, which allows the extension to store data locally on your device. While this permission alone isn't inherently dangerous, it's worth noting for an extension that appears to simply highlight percentages in Google Analytics. The extension operates specifically on Google Analytics pages, which contain sensitive business and website performance data. The small user base and limited review history make it difficult to establish a strong trust foundation.
Given the medium risk level, consider running this extension in a separate Chrome profile if you handle sensitive analytics data. Monitor what data the extension might be storing by checking Chrome's extension storage settings. Since the extension only works on Google Analytics pages, you could disable it when not actively using Analytics to minimize exposure. Consider whether the functionality provided is essential enough to justify the storage permission, or if alternative methods for highlighting percentages might be preferable.
