Hello @autostrada!
It happens because Hustle stores some data ( ip, request uri, time, etc. ) for each showing or submitting forms when tracking is enabled. If you are interesting only to have information about conversation rate and total count of showing and remove additional data ( ip, request uri, time, etc. ) – you could try adding the following snippet in a MU plugin ( more info about MU plugins is here )

<?php
function wpmu_hustle_brief_tracking_data( $data ) {
	return null;
}

add_filter('hustle_tracking_data', 'wpmu_hustle_brief_tracking_data');

The hustle_tracking_data filter will be added in 3.0.7 vesrion of the plugin. Until it’s not there you could add it to inc/hustle-model.php file via FTP to _log function
$data = apply_filters( 'hustle_tracking_data', $data );
before this line
return $this->add_meta( $type, $data );

Also, if you want to delete already existing tracking data – you could temporary add this snippet to the MU plugin

function wpmu_hustle_remove_old_tracking_data() {
	global $wpdb;
	$wpdb->update( $wpdb->prefix . 'hustle_modules_meta', array( 'meta_value' => null ), array( 'meta_key' => 'popup_view' ) );
	$wpdb->update( $wpdb->prefix . 'hustle_modules_meta', array( 'meta_value' => null ), array( 'meta_key' => 'popup_conversion' ) );
}

add_action('init', 'wpmu_hustle_remove_old_tracking_data');

Then refresh any page on your site and remove this part of the MU plugin. Then you should export and import hustle_modules_meta table (it will decrease your 54Mb table to 11Mb).

Best regards,
Ivan.
