Permalink Manager does not collect or transfer any personal data from your website; they are not gathered since there is no need to.
When the plugin is activated, Permalink Manager Pro send requests to the update server that include just necessary (non-sensitive) info to authenticate the license keys and provide direct access to automatic updates.
A sample request looks like this:
