Explain This is a Chrome extension that helps users understand selected web content by generating explanations using Chrome's built-in on-device AI capabilities.

The extension does not intentionally collect:
Names or email addresses
Passwords or authentication information
Financial or payment information
Health information

However, webpage text selected by a user could potentially contain personal or confidential information. Users should avoid selecting sensitive information unless they are comfortable processing that content through Chrome's built-in AI functionality.
Selected webpage text is used only to provide the explanation requested by the user.
