Privacy statement[statement]

With our website "bw-cloud.org" we want to provide useful information about our project, its infrastructure and our service - in combination with a good user experience. Therefore we store some details about your visit in a log file. However, we do not store any complete or reproducible user IP addresses. Your IP addresse will be modified before saving them in our log file. The following information is stored in our log file:

Anonymised IP addresse (details see below)
Date and time
Requested page or file
Amount of data transmitted
Returncode if the access was successful or not
Identification of the browser software ("User-Agent")

The collected information is solely used for statistical purpose and traffic analytics. We do not share or transmit this data with third parties. We also do not use any technologies like java applets, plugins or browser extensions. Data we ask you to provide us via our contact form is solely used for correspondence between you and us. We try to secure our server infrastructure as best as we can. Our main goal is to prevent unauthorized access to our records / data.

Contact form[contactform]

With the help of the contact form provided by us you can comfortably formulate your request to us via browser. Please note the following:

All fields except the last question field are optional. None of the fields must be filled in for contact.
However, it is self-explanatory that we can not respond if none of the fields is filled
The field "Last question" field is used to prevent automated filling out of the form with the help of bots
The data use in the form is limited exclusively to the processing of the respective user request
Data collection and use for additional purposes (such as promotional purposes or sharing them with other parties) is excluded and will not take place

Technical details[tecnical_detials]

We anonymize your IP addresse by applying the apache module mod_anonip before storing the data in the log file. The last two octets are replaced by "0". E.g: the fabricated IP address


    132.230.450.912

will be modified so that it looks like this:


    132.230.0.0

Now, it is not possible to map a request to a given IP address / computer combination, but we can use the data to get some information about the countries of our visitors (geolocation).

Format of the log entries[td_log_format]

Data is stored using this format:


    LogFormat "%h %l %u %t \"%r\" %>s %b \"%{User-Agent}i\"" combined_clean

Overview of the components ("flags") of an entry:

%h: Remote hostname.
Will log the IP address if HostnameLookups is set to Off. Diese IP wird von unserem Webserver teilweise anonymisiert: die letzten beiden Stellen werden mit 0 überschrieben
%l: Remote logname (from identd, if supplied).
This will return a dash unless mod_ident is present and IdentityCheck is set On.
%u: Remote user if the request was authenticated.
May be bogus if return status (%s) is 401 (unauthorized)
%t: Time the request was received, in the format [18/Sep/2011:19:18:28 -0400].
The last number indicates the timezone offset from GMT
%r: First line of request.
%>s: (Final) Status.
For requests that have been internally redirected, this is the status of the original request. Use %>s for the final status.
%b: Size of response in bytes, excluding HTTP headers.
In CLF format, i.e. a '-' rather than a 0 when no bytes are sent.
%{User-Agent}: User-Agent explained by Wikipedia
