Privacy Policy

The Chaostreff Osnabrück e.V. stores just that much personal data as is absolutley necessary in order to offer information and services to visitors and members in reliable and safe way.

We ourselves operate the server as a VServer with all services. An evaluation of the logfiles of the services will be done exclusively by ourselves und only to detect possible errors or intrusion attempts.

We therefore decided explicitely to avoid the usage of cookies and tracking tools for the analysis of the data traffic like e.g. GoogleAnalytics.

We only pass any parts of the collected data according to legal demands e.g. to law enforcement authorities or tax authorities.

Subsequently, we break down exactly at which opportunity we store which data for what time period. The subsequently mentioned password storage does not mean the plain text storage of the password but the storage of the password hashes instead. We further describe the steps necessary to delete those data that are not deleted automatically.
