1. What we use and why
A cookie is a small file a site stores in your browser. This site uses them for one thing only: to know how many people visit and which pages they look at, via Google Analytics. There is no advertising, no profiling and no tracking across other websites.
These cookies are not set until you accept them. Until you decide, and also if you decline, Google’s code is never loaded. Declining limits nothing: you can read the whole site and download the application just the same.
2. Cookies used

Your decision about this notice is stored separately, in the browser’s local storage, under the key luft.consent. It is not a cookie: it is not sent to the server with each request and serves only to avoid asking you again. It is exempt from consent because it is strictly necessary to honour the consent you expressed.
3. Who receives the data
Google Ireland Limited, as the analytics service provider. Processing may involve Google LLC in the United States under the EU-US Data Privacy Framework. See how Google uses data from sites that use its services and its privacy policy.
Data is retained for 14 months.
4. Changing your mind
Withdrawing consent is as easy as giving it and has no consequences. Use the control at the end of this page.
You can also delete or block cookies from your browser settings; if you clear this site’s storage, the notice will appear again next time you visit.
5. More information
The full processing details, legal bases and your rights are in the privacy policy.
