This privacy policy explains how TubeTuner ("the extension") handles user data. We are committed to protecting your privacy and ensuring transparency.

1. Personal Data Collection

We DO NOT collect, store, use, or share any personally identifiable information (PII).

This extension operates entirely on your local browser. We do not have any servers, and we do not transmit any personal data to any third party or to ourselves.

2. User Settings and Data Synchronization (chrome.storage.sync)

To provide a consistent experience across your devices, the extension uses the chrome.storage.sync API.

• What this means: Your personal settings for the extension (such as layout preferences, theme choices, etc.) are saved and synchronized with your Google Account.
• Our Access: We, the developers, DO NOT have access to this data. This data is managed by Google and is tied directly to your personal Google Account. We cannot read, collect, or see these settings. This is a feature provided by the browser for your convenience.

3. Analytics and Tracking

We DO NOT use any analytics or tracking tools (such as Google Analytics). We do not track your browsing activity, clicks, or any other user behavior.

4. Extension Permissions

The extension requests permission to access *://*.youtube.com/* for the sole purpose of its core functionality: applying your chosen customizations (CSS and JavaScript) to the YouTube website. No data is read from the page for any other purpose, and no data is stored or transmitted.

5. Changes to This Policy

We may update this privacy policy in the future. Any changes will be posted on this page.
