Privacy Policy
Last updated: February 04, 2026
1. Overview
At Tube Flash Kit, we believe in privacy by design. Our extension is built to enhance your YouTube experience without compromising your personal data. We do not track your browsing history, we do not sell your data, and we minimize data collection to the absolute essentials required for functionality.
2. Data Collection & Usage
Local Storage (Default)
By default, all your data (playlist progress, settings, preferences) is stored locally on your device using `chrome.storage.local`. This data never leaves your browser.
Cloud Sync (Optional)
If you choose to sign in with Google, we use Firebase Authentication and Realtime Database to sync your settings preferences (e.g., "Focus Mode: On") across your devices. We do not sync your watch history or personal browsing data to the cloud.
3. Permissions Explained
- storage: Used to save your settings and playlist progress locally.
- scripting / activeTab: Used to inject functionality (like the progress bar or screenshot button) directly into the YouTube page you are viewing.
4. Third-Party Services
We use Google for optional user authentication and settings synchronization. Please refer to Google's Privacy Policy for more details on how they handle data.
