Cookies & storage
This site sets no advertising or tracking cookies, so there's no cookie banner. Here is everything it stores in your browser.
Your sound setting
Key “fda:sound” in your browser's local storage remembers whether you turned the interface sounds on or off. It never leaves your device.
Error diagnostics
When error diagnostics are active, Sentry may keep a short-lived session identifier in session storage, so an error and the moments before it can be linked. It's cleared when you close the tab.
Intro animation
Key “fda:intro” in session storage remembers that the opening animation already played, so it shows once per visit. It's cleared when you close the tab.
Visit statistics
Our visit statistics use no cookies and store nothing in your browser. Details are in the Privacy Notice.
Clearing it
You can clear local and session storage at any time in your browser's settings. The site keeps working without it.
