3FX Mixer ("the Extension", "we", "us", or "our") is a real-time multi-track audio mixer, parametric equalizer, DSP effects processor, and 3D visualizer extension for Google Chrome.
We believe privacy is an essential right. This Privacy Policy details our data handling practices and affirms that 3FX Mixer does not collect, record, transmit, or monetize your personal information or audio streams.
When you capture a browser tab's audio, all signal processing (including 10-band graphic EQ, parametric EQ, dynamic compression, tape saturation, phasing, reverb, limiter, and visualizer rendering) is executed 100% locally in-memory on your computer using the standard Web Audio API and WebGL:
The extension uses Chrome's local storage API (chrome.storage.local) strictly on your machine to save user configuration:
This information is stored exclusively on your device and is never synced, uploaded, or transmitted to any external server.
To deliver audio mixing and real-time DSP effects within Google Chrome's Manifest V3 architecture, the extension requests the following permissions:
| Permission | Purpose |
|---|---|
| tabCapture | Routes audio from the active browser tab into the local Web Audio processing rack. |
| offscreen | Allows the Web Audio API context and audio worklets to run reliably in a dedicated offscreen document as required by Chrome Manifest V3. |
| tabs & activeTab | Identifies media-playing tabs (title and favicon) so you can distinguish and control channel strips in the mixer dashboard. |
| storage | Saves your mixer presets, custom effects settings, and UI themes locally on your machine. |
| scripting | Synchronizes media playback controls and volume adjustments on compatible web players upon user activation. |
| <all_urls> | Enables you to mix audio across any website playing media. |
This extension may display non-intrusive advertisements provided by third-party monetization partners, including PlayaYield.
To deliver and measure ads safely, limited technical information (such as approximate IP address, browser type, device type, and ad interaction events) may be processed by the advertising network in accordance with industry standards.
Ad requests are isolated within sandboxed containers and never have access to your tab audio, browsing history, or mixer settings. For more information regarding PlayaYield's data practices, please consult the PlayaYield Privacy Policy.
3FX Mixer does not contain any third-party behavioral analytics, telemetry beacons, or tracking pixels.
3FX Mixer operates within the secure sandbox architecture enforced by Google Chrome's Manifest V3. Because audio processing and state storage take place solely in local device memory, your media and activity cannot be intercepted or exposed by external cloud infrastructure.
The extension is intended for general audiences. Because we do not collect personal information of any kind, we do not knowingly solicit or collect data from children under the age of 13.
We may occasionally update this Privacy Policy to maintain compliance with updated Chrome Web Store policies or browser requirements. Updates will be published on this page with a revised "Last Updated" timestamp.
If you have any questions, feedback, or concerns regarding this Privacy Policy or the data practices of 3FX Mixer, please submit an issue or inquiry via our official extension support page or repository.
