YouTube Stat Tracker Data Handling Policy

Data Processing & Privacy
Last updated: 7/4/2025

Overview

YouTube Stat Tracker is designed with privacy as a core principle. This application processes your YouTube viewing data locally in your browser to generate statistics and insights about your viewing habits. No data is collected, stored, or transmitted to external servers, unless explicitly stated below.

Data Collection

We do not collect, store, or transmit any personal data. The application operates entirely within your browser environment and does not maintain any databases or servers that store user information.

  • No personal information is collected or stored
  • No user accounts or profiles are created
  • No tracking cookies are used
  • No analytics or monitoring services are integrated

Data Processing

When you use this application, your YouTube data is processed in the following manner:

  1. Local Processing: All data analysis occurs within your browser's memory
  2. Temporary Storage: Data is held only in browser memory during active use
  3. Immediate Disposal: All data is automatically flushed when you close the browser tab or navigate away
  4. No Persistence: No data is saved to your device's storage or sent to external servers

Google API Usage

When using the Google Takeout integration feature:

  • OAuth Authentication: Google's secure authentication system is used to access your data
  • Limited Scope: Only YouTube viewing history data is requested
  • Direct Transfer: Data flows directly from Google to your browser without intermediate storage
  • Temporary Access: Authentication tokens are used only for the duration of data retrieval

Third-Party Services

The application may make API calls to:

  • YouTube Data API: To fetch video metadata for enhanced statistics (duration, thumbnails)
  • Google Data Portability API: To retrieve your YouTube viewing history

These API calls are made directly from your browser and are subject to Google's privacy policies. No data from these requests is stored or logged by our application.

Data Security

  • All data processing occurs in your browser's secure sandbox environment
  • No data transmission to external servers (except Google APIs as described)
  • HTTPS encryption is used for all external API communications
  • No persistent storage of sensitive information

Your Rights

Since no data is collected or stored, you maintain complete control over your information:

  • You can stop processing at any time by closing the browser
  • No deletion requests are necessary as no data is retained
  • You can revoke Google API access through your Google Account settings
  • All processing is voluntary and user-initiated

Changes to This Policy

This privacy policy may be updated to reflect changes in our data handling practices. Any updates will be posted on this page with a revised "Last updated" date. Given the nature of this application (no data collection), substantial changes to our privacy practices are unlikely.
