Pro Thumbnail Preview for YouTube

Privacy Policy for PRO Thumbnail Preview

Last Updated: January 25, 2026

1. Introduction PRO Thumbnail Preview ("we", "us", or "our") respects your privacy. This Privacy Policy explains how our Chrome Extension handles your data. We are committed to protecting your personal information and your right to privacy.

2. Data Collection and Usage We do not collect personal browsing history, search history, or website content. The extension operates locally on your device to modify the DOM (Document Object Model) of YouTube pages for preview purposes.

We collect and process the following limited data types:

• Authentication Information (License Keys): When you activate the PRO version, you enter a license key. This key is transmitted securely to our validation server (Cloudflare Worker) and verified against the Lemon Squeezy API to confirm your purchase status. We do not store payment details (credit cards, bank accounts); these are handled entirely by Lemon Squeezy.

• User Activity & Location (Google Analytics): We use Google Analytics to collect anonymous usage data to help us improve the extension. This includes:

  • Button clicks (e.g., how often "Blur Test" is used).

  • General location data (Region/Country) derived from IP addresses (IP anonymization is enabled).

  • Error logs to identify bugs.

3. Permissions The extension requires specific permissions to function:

• Host Permissions (YouTube.com): To identify thumbnail elements and overlay the preview interface.

• ActiveTab: To trigger extension features without refreshing the page.

• Host Permissions (prothumbnailpreview.com): Required to securely fetch and display educational images and assets for the "Thumbnail Pro Tip of the Week" feature.

• Storage: To save your preferences (e.g., saved title ideas) and license status locally on your browser.

4. Third-Party Services We use the following trusted third-party services:

• Lemon Squeezy: For license management and payment processing.

• Google Analytics: For anonymous usage statistics.

• github: To fetch static configuration data (e.g., educational tips).

• prothumbnailpreview.com: To host and deliver educational media (images) for in-app creator tips. No user data is sent to this domain; it is used strictly for downloading static assets. 

5. Data Sharing We do not sell, trade, or rent your personal identification information to others. We do not transfer data to third parties outside of the specific use cases mentioned above (license validation and analytics).
