Built for Privacy
Prism EQ processes all audio locally, directly in your browser. No audio, settings, or browsing data is ever collected, transmitted, or sold. Your EQ settings and presets are stored only in your browser's local storage — nothing leaves your device. There's no remote code and no analytics, so what you see in the source is exactly what runs.
Simple Permissions, Clear Purpose
Prism EQ requests only what it needs to function:

Tab audio capture – to process and play back the audio of the tab you enable
Active tab access – to authorize capture only on the tab you click
Local storage – to save your settings and presets on your device
Side panel – to display the equalizer interface

No broad host permissions, no background tracking.
Perfect For
