Product: Sanctum Chrome Extension

This policy explains how Sanctum handles data. Sanctum is designed to help users pause and choose again when YouTube recommendations, autoplay, or Shorts carry them away from their original viewing purpose.

1. Summary

• Most Sanctum data stays on the user's device in Chrome local storage.
• Sanctum processes limited YouTube navigation and interaction signals to provide its user-facing features.
• Sanctum does not transmit YouTube URLs, video titles, search terms, page body text, or YouTube account information to the developer's servers.
• Optional product-improvement data is sent only after the user enables improvement feedback.
• Free-text feedback is sent only after the user explicitly presses a send button.
• After at least 14 completed Evidence Mode days, the user may preview and send one fixed-field aggregate summary one time. This is separate from the improvement-feedback setting and is never sent automatically.
• An optional uninstall survey may open after removal.
• Sanctum does not sell user data or use it for personalized advertising, credit, lending, insurance, employment, or eligibility decisions.

2. Data processed locally on the device

To provide its disclosed single purpose, Sanctum may process the following information locally:

YouTube page and interaction state

• Whether the current supported page is YouTube Home, a watch page, Shorts, search, or another supported YouTube surface
• Recommendation navigation, autoplay transitions, Shorts swipes, video play/pause state, and timing needed to decide when to show a checkpoint
• Whether a Sanctum dialog, timer, or Cherry Break is currently active
