Analytics (with your consent)
We may use Plausible to count visits. This measurement is disabled by default. The script is only loaded if you click “Accept” in the banner.
Plausible measures page views, the general origin of visits (referring site), the device type and the country. It does no cross-site tracking and doesn’t create an advertising profile. See the privacy policy.
Declining is as easy as accepting. If you decline, no measurement script is loaded.
Regardless of that choice, and without any cookie or script, the site counts server-side the openings of your player area pages (plan, diagnostic, cheat sheet), per day, without the time of day or the IP address. This is described in the privacy policy, section “Usage measures, without trackers”.
