Google Analytics also uses "cookies", which are text files placed on your computer, to help the website analyze how users use the site. It is not excluded that the information generated by the cookie about your use of this website will be transmitted to and stored by Google on servers in the United States. The transmission of personal data to the USA was judged by the European Court of Justice to be fundamentally unsafe without further security measures, as it cannot be ruled out that US security authorities may gain access to this data.

Only in exceptional cases will the full IP address be transmitted to a Google server in the USA and shortened there. A data transfer to the USA only takes place if the requirements of Art. 44 et seq. DSGVO are fulfilled. On behalf of the operator of this website, Google will use this information for the purpose of evaluating your use of the website, compiling reports on website activity and providing other services relating to website activity and internet usage to the website operator. The IP address transmitted by your browser as part of Google Analytics will not be merged with other data from Google. The user data is deleted after 24 months.
You can revoke your consent at any time with effect for the future and prevent the use of data by Google by downloading and activating the available browser plugin: http://tools.google.com/dlpage/gaoptout?hl=de.

The app can also be used anonymously, i.e. without creating a user account.

You can delete your user account independently at any time. Please note that the recovery of data after deletion of the user account is not guaranteed.
