The only data we have, is when a customer contacts us via email for support or a question and the Customer emails provided by Atlassian Marketplace when customers get a license of our plugins.
We use Google Analytics to make statistics about this website.
Thoses emails are used to answer your requests, and, if you agree, to contact you about important changes in plugins.
All thoses Email adresses are stored, in a secure manner in order to prevent unauthorized access to them.
