Your Data
The databases of freisein and all text, images and files that you save to the platform are stored in a data center in Germany. If you delete content, it will also be deleted physically from the disk.

When you are logged in, your browser (as with any login site on the Internet) transmits an authentication code on every page request, so the server knows that you are the one who makes the request. This code is also called a cookie, is about 60 random characters long and varies for each login.

Until you log out, your browser stores the cookie in its database, so you're automatically logged in when you load the page again. Once you log out, the cookie is deleted. Therefore, always do log out if you're using a PC that's not yours.

When you surf the Internet, your browser transmits its program name and version number, type of operating system, IP address, and a few other technical information on each page that you load. freisein summarizes these data and receives regular, anonymous visitor statistics to find out how many people with what Brower, operating system or country use the platform.

Most other sites on the Internet automatically pass this information and your surfing habits on to other companies for reasons of personal advertising or statistical analysis. freisein does not.
