To write comments and play my games, you need to register an account on this website, which is linked to an email address. Your email address is used only for account creation, password resets and delivery of account status information. Your data is never shared with any third party. For the sake of everyone involved I still recommend to use non-personal emailadresses and not your main password. You can fully delete your account at any time.
For page analytics as well as spam protection, the WordPress Plugin Slimstat is in place, which reveals public IP adresses to the site owner. All data collected in this fashion is deleted automatically after 14 days and is not used for anything other than ensuring the site works normally.
