SlopBlock Privacy Policy

Last Updated: November 3, 2025 Version: 1.0.0 (Phase 4 Complete)

Our Commitment to Privacy

SlopBlock is designed with privacy-first principles. We believe in transparency, minimal data collection, and user control. This privacy policy explains what data we collect, why we collect it, and how it’s used.

Summary (TL;DR)

What Data We Collect

1. Extension Installation ID

What: A randomly generated UUID (e.g., f47ac10b-58cc-4372-a567-0e02b2c3d479)

When: Generated on first run of the extension

Stored: Locally in your browser (Chrome storage API)

Purpose: Prevents duplicate reports and enables the “remove report” feature

Sensitive: No - completely random, not linked to any personal information

Example:

{
  "extension_id": "7e8d9f0a-1b2c-3d4e-5f6a-7b8c9d0e1f2a"
}

2. Video Report Data

What: YouTube video IDs and your extension ID when you report a video

When: Only when you click the “Report” button

Stored: In our Supabase (PostgreSQL) database

Purpose: Track community reports and display warnings when trust threshold is met

Sensitive: No - video IDs are public, extension IDs are random

Phase 3 Addition - Trust Fields:

Example:

{
  "video_id": "dQw4w9WgXcQ",
  "extension_id": "7e8d9f0a-1b2c-3d4e-5f6a-7b8c9d0e1f2a",
  "channel_id": "UCuAXFkgsw1L7xaCfnd5JJOw",
  "reported_at": "2025-01-31T12:34:56Z",
  "trust_weight": 0.65,
  "accuracy_status": "pending"
}

3. Trust Score Data (Phase 3)

What: Your extension’s trust score and accuracy statistics

When: Calculated automatically based on your reports over time

Stored: In our Supabase (PostgreSQL) database

Purpose: Prevent abuse from fake accounts while allowing legitimate users to contribute

Sensitive: No - just numerical scores tied to random extension ID

Example:

{
  "extension_id": "7e8d9f0a-1b2c-3d4e-5f6a-7b8c9d0e1f2a",
  "trust_score": 0.75,
  "accuracy_rate": 0.82,
  "accurate_reports": 14,
  "inaccurate_reports": 3,
  "pending_reports": 8,
  "first_seen_at": "2025-01-01T10:00:00Z"
}

4. User Settings

What: Your preferences (e.g., auto-hide enabled/disabled)

When: When you change settings in the popup

Stored: Locally in your browser (Chrome storage API)

Purpose: Remember your preferences across browsing sessions

Sensitive: No - just boolean flags

Example:

{
  "auto_hide_enabled": false
}

5. Local Cache Data (Phase 4)

What: Marked video IDs cached locally for instant performance

When: Downloaded automatically in background (hourly full blob + 30-min delta syncs)

Stored: Locally in your browser (IndexedDB)

Purpose: Enable instant video checks without server calls

Sensitive: No - just public video IDs and timestamps

Note: This data never leaves your device. It’s a local performance cache only.

Example:

{
  "video_id": "dQw4w9WgXcQ",
  "effective_trust_points": 3.2,
  "is_marked": true,
  "cached_at": "2025-11-03T14:22:00Z"
}

What Data We DON’T Collect

We explicitly do not collect:

How We Use Your Data

Primary Use: Community Reporting with Trust System

  1. You report a video as AI-generated
  2. We store the video ID + your extension ID + trust weight
  3. We calculate effective trust points (sum of all weighted reports)
  4. If trust points ≥ 2.5, we show warnings to all users
  5. Your individual reports remain anonymous
  6. After 30 days, your report’s accuracy is evaluated to improve your trust score

Secondary Use: Trust & Accuracy

Tertiary Use: Statistics

Local Caching (Phase 4)

Data Storage & Security

Infrastructure

Hosting: Supabase (secure PostgreSQL database)

Encryption:

Access Control:

Data Retention

Reports: Retained indefinitely for community accuracy and trust evaluation

Trust Scores: Retained indefinitely (tied to anonymous extension ID)

Extension IDs: Retained indefinitely (but anonymous)

Deleted Reports: If you remove a report, the report is deleted but trust history remains
