Smush sends images to the WPMU DEV servers to optimize them for web use. This includes the transfer of EXIF data. The EXIF data will either be stripped or returned as it is. It is not stored on the WPMU DEV servers.

Smush uses a third-party email service (Drip) to send informational emails to the site administrator. The administrator’s email address is sent to Drip and a cookie is set by the service. Only administrator information is collected by Drip.
