4. Third-Party Services
Analytics: We use Google Analytics and Google Tag Manager to understand how visitors use our Site. Google may collect and process data as described in their privacy policy.

External URLs: When you submit a URL for preview, our server makes a request to that URL to fetch its meta tags. We do not control the content or privacy practices of those external websites.

5. Data Retention
Cached preview data is automatically deleted after 24 hours. Analytics data is retained according to Google Analytics' default retention settings. Server logs are retained for up to 30 days.

7. Data Security
We implement reasonable security measures to protect your personal information from unauthorized access, alteration, or destruction. Our service includes SSRF protection to prevent abuse of the URL fetching feature. However, no internet transmission is completely secure, and we cannot guarantee absolute security.
