Privacy Policy

1. Basic Policy

e-Toolbox ("this Service") places great importance on protecting user privacy. This Privacy Policy explains what information we collect and how we use it.

2. Information We Collect

2.1 Data Entered When Using Tools
Most tools process input in your browser. The OGP checker sends the entered URL to our server to fetch the page and its redirects and extract metadata. Metadata is cached on the server to reduce repeated requests, with revalidation after approximately 60 seconds. Image URLs are sent to the server, which validates public access and retrieves the images without storing them. A hash of the client IP address is temporarily held in memory to limit repeated requests.

2.2 Analytics Information
We use Google Analytics 4 to analyze site usage. The following information may be collected:

• Page views and session counts
• Device and browser type
• Geographic location (city level)
• On-site behavior data

3. Purpose of Information Use

• Service improvement and feature enhancement
• User experience optimization
• Site performance analysis
• Identification and resolution of technical issues

4. Sharing Information with Third Parties

This Service does not share collected information with third parties except in the following cases:

5. Cookies and Browser Storage

This Service uses cookies through Google Analytics for the following purposes:

Favorites stores only your selected tool IDs in this browser’s localStorage. No login is needed, and this information is not sent to our server. Favorites remain in the same browser until you remove them using the star buttons or clear site data. Search queries are not saved.

You can disable cookies through your browser settings, but some features may be limited.
