In-depth safety analysis
This extension requests the tabCapture permission to access audio from browser tabs, which is essential for applying equalizer effects to playing media. The tabs permission lets it identify which tab is producing sound, while storage saves your custom settings and offscreen enables background audio processing under Manifest V3. For an audio equalizer, this permission set is expected and tightly scoped to its core functionality.
Audio-processing extensions inherently have the capability to capture tab audio, which could include sensitive content like voice calls or banking alerts if a user is not mindful. As with any extension that can read audio, careful users should only install from trusted sources and verify that the extension’s behavior matches its stated purpose. The developer’s declared privacy practices indicate that data is not sold or used for unrelated purposes, which aligns with a low-risk profile.
The extension’s strongest dimension is Maintenance & Ownership, scoring 100%, suggesting it is actively updated and well-maintained. Its weakest area is Publisher & Identity at 60%, reflecting limited public information about the developer—a common situation for smaller or independent publishers. This does not imply any wrongdoing, but users who prioritize a well-known corporate entity might note the lower transparency.
AI-assisted analysis of the documented signals above (permissions, store data, privacy practices) — explains what they mean and the risks typical for this category. Not a hands-on test.
