Browser Extension & Website (mutefeed.com)

Effective & Last Updated: November 8, 2026
// ARCHITECTURAL GUARANTEE: 100% LOCAL EXECUTION

MuteFeed does NOT collect, store, transmit, rent, or sell any personal data, browsing history, or user content. The extension operates strictly locally inside your browser with zero external server communication.

1. Zero Data Collection Policy (Chrome Extension)

MuteFeed ("the Extension"), engineered by PRYSKY, is built on a strict local-first architecture. When you install and use MuteFeed on Facebook™:

  • No Personal Information: We do not collect your name, email address, Facebook profile ID, credentials, or IP address.
  • No Browsing or Feed Tracking: We do not read, log, or transmit the content of your feed, messages, friend lists, or interactions to any remote server.
  • No Analytics or Telemetry: The Extension contains zero third-party analytics scripts, tracking pixels, or telemetry SDKs.

2. How Local Storage Is Used (chrome.storage.local)

MuteFeed utilizes the browser's native chrome.storage.local API exclusively on your own device to remember your interface preferences:

  • Your active filter checkbox states (e.g., Mute Stories, Mute Reels, Mute Ads, Mute Suggested Posts/Pages, Mute Friend Suggestions, Mute Suggested Groups, Hide Right Column).
  • Your Chronological Feed toggle state (Show Recent Posts).
  • Your personal list of muted post authors/sources (Muted Sources) that you explicitly choose to silence in your feed.

This data never leaves your local browser environment and is immediately erased if you uninstall the Extension.

3. Host Permissions Justification

MuteFeed requests access solely to *://*.facebook.com/* in order to apply real-time DOM/CSS filtering rules that hide algorithmic clutter (Reels shelves, Story trays, and unconnected recommendations) directly on the page before or as they render. The Extension has no access to any other websites.

4. Website Interactions (mutefeed.com)

Our informational website (https://mutefeed.com) is a static publication and does not use tracking cookies or behavioral profiling. If you voluntarily contact our studio via email regarding technical support, partnerships, or investment inquiries, your email address and message are used strictly to respond to your inquiry and are never shared with third parties.

5. Compliance with Chrome Web Store User Data Policy

MuteFeed's handling of technical permissions adheres strictly to the Chrome Web Store Developer Program Policies, including the Limited Use requirements.
