Supperman is a set of static pages. There is no account system, no newsletter, no comment section and no advertising. Nothing you do here is stored on a server belonging to us, because there is no application server behind this site. The pages do carry Google AdSense, explained below.
Every page loads Google AdSense (client ca-pub-3205506069395369). Google and its partners may set third-party cookies or read device identifiers in order to serve, cap and measure ads. We never receive that data — it stays between your browser and Google.
You can turn personalised advertising off in Google Ads Settings, or refuse third-party vendor cookies at aboutads.info. Google explains its own use in How Google uses information from sites that use its services.
Diagnosis, teaching steps, the practice round and the search box all run as JavaScript on your own device. The answers you click are never transmitted anywhere — they exist only in the page's memory and disappear when you close the tab.
Like every website, the hosting provider keeps standard access logs: IP address, user agent, timestamp and requested path. These are used for security and for diagnosing delivery problems, and are not combined with anything else. They are not used to build a profile and are not sold or shared.
If you write to us, we receive your email address and whatever you put in the message. It is used only to reply, and is not added to any list.
Under the GDPR and comparable laws you may ask what data is held about you. In practice the answer is: only the email you chose to send. Requests go to [email protected].
If this policy changes, the date below changes with it. There is no version to accept — the site has nothing to accept.
