When you first install Advanced Page Visit Counter, you will see this optin form powered by Freemius asking if you’d like to share non-sensitive diagnostic data with us:

We collect some data to understand our users better, but you can choose not to share it. The data includes basic information about your site’s setup and helps us with troubleshooting.

Using Freemius makes it easier for us to offer Independent Analytics Pro and manage licenses and updates for you.

Freemius doesn’t access your website’s analytics data, so it doesn’t affect your site’s GDPR compliance or user privacy.
