Feed Filter

Transparency Report

Last Updated: July 2025

Technical overview of Feed Filter's data flows and privacy safeguards implemented. We value and strive to maximize the degree of data sovereignty that is possible while still delivering your filtered feed.

Content Terms We Use

In this report, terms like clickbait, ragebait, misleading content, misinformation, fake news patterns, toxicity, and low-quality AI slop describe public-post patterns that are commonly associated with distraction, doomscrolling, and information overload. These labels are used to classify content patterns, not to make legal claims about any person.

Executive Summary

Does browsing history leave your device?No. Only public posts you're already viewing are analyzed.
Is data tied to real identity?No. After initial auth, all operations use anonymous IDs.
Is the code auditable?Client-side code is viewable from the Chrome download.

Data Flow Analysis

1. Authentication (One-time)

  1. Google OAuth provides temporary authorization code
  2. Backend exchanges code for ID token (never stored)
  3. Anonymous user account created with cryptographically secure unique identifier (CUID)
  4. JWT issued containing only anonymous ID + subscription status
  5. Google credentials immediately discarded

2. Post Analysis

Text-Only Posts:

Post text → Cloudflare Worker → OpenAI API → Filter decision

Media Posts:

Image URL → GPU Server → OCR/Caption → OpenAI API → Filter decision

3. Data Storage

  • Settings and feedback stored in Firebase (Google Cloud)
  • No cookies or tracking pixels
  • IP addresses are visible to our hosting providers (Vercel, Firebase, Cloudflare) for infrastructure purposes but are not used by Feed Filter for tracking or user identification
  • No cross-site tracking
  • Cache stored locally in your browser only
  • User data (settings, feedback, filter decisions) retained indefinitely to improve service quality

Platform Features vs Feed Quality

Native controls such as muted words, account restrict, and “not interested” signals can help, but they are often weak against platform-level ranking systems and dark patterns in For You-style feeds. Feed Filter is built to give users an external, user-controlled layer for time management and feed quality.

We believe in radical transparency. If you have questions about our data practices or want to verify any claims in this report:
