Cookies & local storage
This page explains which cookies and similar storage this website uses and what they are for. We do not use any advertising or third-party tracking.
What are cookies?
Cookies are small text files stored on your device. Alongside cookies, websites can also use the browser's local storage. Both let a site remember information between visits, for example your chosen language or display settings.
Necessary
These are required for the site to work and are always active.
- Your selected language, so the correct version is shown.
- Your decision from the cookie banner, so it is not shown again.
- An admin session, only while an administrator is logged in.
- The offline cache of the service worker, holding only technical files.
About the offline cache: It stores stylesheets, scripts and icons on your device so the site loads faster and stays usable on a poor connection. It holds no content about you and nothing that would allow conclusions to be drawn about you, so it is set up without consent and stays in place if you choose "Only necessary". You can clear it at any time in your browser settings.
Functional (preferences)
These make the site behave the way you have set it up. They are stored in your browser's local storage. Most of them only come into being once you use the feature concerned; a few the site creates on its own, for example the placeholder name in the header or the cache of the statistics data.
- Layout, theme and font preferences.
- A placeholder name and picture for the header, generated on your own device.
- Which redeem codes you copied or reported.
- Whether you dismissed the update banner.
- Push notifications for new codes, only if you actively subscribe.
Important: If you choose "Only necessary", these settings are not stored at all: entries that already exist are deleted and the settings are shown greyed out, because without storage they cannot be remembered. As long as you have not decided yet, they apply for the current visit only.
