Link Whisper does save some site visitor data as a function of the Click Tracking. The data is used to provide greater detail in the click stats and is only stored on your site. Link Whisper does not have cloud storage capabilities, so the data is always in your possession. The data Link Whisper tracks are:

• The visitor’s IP address.
• The visitor’s site ID. (If they are logged in.)

This data is collected when a user clicks on a link and is associated with the tracked link click. Visitors that don’t click links will not be tracked.

All of the visitor data can be deleted, and you can set Link Whisper to not collect visitor data.
