This extension does not do anything unless you click the Send to Kindle button. We do not monitor or inject any scripts into your pages while you browse.

When you click the Kindle icon, this extension sends the contents of the page and its URL to the KTool service. The KTool service then packages the contents into a reader-ready format and delivers it to your Kindle.

Content which you process with the KTool service will be cached on the server for a short period.
