1. Zero Server Processing
At YouThumb, your privacy is our highest priority. We do not process, store, or log any of your YouTube URL queries on our servers. The entire extraction mechanism operates entirely within your own web browser using Client-Side JavaScript.
2. Local Storage (Cookies/Cache)
We use your browser's Local Storage strictly to enhance your personal user experience. This includes:
- Saving your preferred language setting (e.g., English, Korean).
- Keeping a temporary history of up to 5 recently extracted thumbnails so you can quickly revisit them. This data never leaves your device and can be cleared at any time by clearing your browser cache.
3. Third-Party Services
We may use basic third-party analytics (like Google Analytics 4) to monitor general website traffic, uptime, and performance. This data is aggregated and completely anonymized. Furthermore, our site may display advertisements via Google AdSense, which may use cookies to serve ads based on your prior visits to this or other websites.
4. No Personal Information Collected
Because there is no account registration or login required to use YouThumb, we do not collect names, email addresses, phone numbers, or any personally identifiable information (PII).
5. Changes to This Policy
We reserve the right to update or change our Privacy Policy at any time. Any changes will be posted on this page immediately.
