Privacy policy and Data security on karlsruhe.de

Privacy Policy

The following statement explains the exact details of what data is saved on karlsruhe.de, the internet site of Karlsruhe City, and how this data is handled by Karlsruhe City. Karlsruhe City will act in accordance with current legis­la­tion.

In addition to this, we would also like to offer you some advice about how you can help to protect your data yourself.

Be aware, however, that our internet site contains links to other websites. We cannot be respon­si­ble or liable for external websites. We also do not have any influence over whether other organi­sa­ti­ons observe data protection stipu­la­ti­ons.

1. Data protection obliga­tion

Karlsruhe City undertakes to protect the privacy of all persons who entrust their data to it. As a public body it is subject to more far-reaching legal data protec­tion regula­ti­ons than private companies. Laws in force form our basic principles, laws such as the Bundes­da­ten­schutz­ge­setz (BDSG) (Federal German Data Protection Law), the Landes­da­ten­schutz­ge­setz of Baden-Württem­berg (LDSG-BW) (Baden-Württem­berg State Data Protection Law), the Gemein­de­ord­nung für Baden-Württem­berg (GemO) (Baden-Württem­berg Local Government Code), the Kommu­ni­ka­ti­ons­dien­ste­ge­setz (IuKDG) (Commu­ni­ca­ti­ons Services Law) and the Staats­ver­trag über Medien­diens­te (Medi­en­dienste-Staats­ver­trag) (State Law for Media Services).

2. Collection of personal data

Personal data is not actively tracked or collected by Karlsruhe City. It expressly encourages users of karlsruhe.de to use techno­lo­gies which protect against the unnoticed obtainment of personal data (e.g. blocking cookies, non-disclosure of HTTP address, conceal­ment of the inquiring IP address - more on this topic below). We ensure that if you do use such techno­lo­gies you can still access karlsruhe.de.

Only such personal data which you delibe­ra­te­ly commu­ni­cate to us within the scope of a transac­tion is saved electro­ni­cally by Karlsruhe City. The saved data on karlsruhe.de is protected in particular by means of organi­sa­tio­nal and technical measures taken by Karlsruhe City.

3. Storage of personal data

Saved personal data is only used for purposes which were commu­ni­ca­ted to us by you or which we have informed you of beforehand. In particular, you can be sure that data will never be handed on to third parties for commer­cial purposes without having your explicit consent.

Storage of logging data

When you access the pages of karlsruhe.de infor­ma­tion of a general nature is automa­ti­cally collected. This saving of logging data is not a specific function of karlsruhe.de, it takes place on every website on the internet.

What data is stored?

During every access the following infor­ma­tion is saved:

  • Name of the requested file

  • Date and time you accessed our site

  • Trans­fer­red data volumes

  • Status message indicating whether the request was successful or not

  • Operating system used to access our site

  • IP address of the computer from which the infor­ma­tion request was sent

  • Web browser used to access our site

  • If you linked to karlsruhe.de from another website, the address of that website (HTTP referrer).

Personal user profiles cannot be formed from this infor­ma­tion.

All saved logging data is deleted by us after sixty days at the latest.

With some browsers, it is possible to stop the trans­mis­sion of the HTTP referrer and the type of browser used or arbitra­rily change the type of browser used (e.g. Opera, Konqueror). Use this oppor­tu­nity if it appears to be wise for you to do so. We make no endeavours whatsoever to verify or check the data.

The IP address is almost always the number of the computer of your ISP, not that of your personal computer. Normally, your computer does not have a permanent IP number but is allocated a temporary one at every dial-up. This temporary IP address cannot be traced back. If you want to be parti­cu­larly safe, you should use a proxy. Enquire with your ISP about this. Karlsruhe City does not undertake any attempts to track you from your IP number.

Purpose of saving logging data

Storing logging data helps to guarantee opera­tio­nal relia­bi­lity. With the data, we are able to assess where mistakes occur in our service and react accor­din­gly.

In addition we constantly aim to improve our service and make it more appealing. We can only optimise the content according to your demands if we know which areas of our website are visited the most.


What are cookies?

A cookie is a small text file which, with your permission, is stored on the hard drive of your PC. In effect, it is the purpose of a cookie to analyse and comprehend web traffic when you visit a certain website. Cookies allow a web appli­ca­tion to address you indivi­dually. Thus, there is also the danger that cookies could compile personal profiles.

Cookies are not programs and can therefore not cause damage to your PC.

Usage of cookies on karlsruhe.de

Most of the time, no cookies are used on karlsruhe.de. On the newer webpages, we use two cookies:

The first cookie serves to note the preferred language which the user has chosen on sites which are available in several languages. If you did not have cookies, the German version would be chosen after every click.

The second cookie serves a similar purpose. With this one, whether the user is in the text or the graphic version is registered so that the following page is shown correctly.

Otherwise cookies are only used for webpages which are reserved to a very defined set of users.

All cookies from karlsruhe.de originate from the server called up and are deleted at the end of the session. Should an exception occur and this is not the case, we will point it out to you.

Every current browser can be configured so that cookies will not be accepted.

If absolute anonymity is important to you, please ban cookies. You will still be able to use Karlsruhe.de.

If you want to surf more comfor­ta­bly, please ban cookies which:

  • do not come from the same server
  • remain saved after the end of the session.

How do we protect your data?

We use a safe trans­mis­sion procedure, so-called SSL trans­mis­sion, in order to process your data. This means that all infor­ma­tion which comes from you is encrypted using this safety procedure before it is sent to us.

Why encrypt the data?

The internet is an open network. When you send data from one point to another, it is directed through many stations at which it could be read without great difficulty. Trans­mit­ting data on the internet is therefore as open as sending a postcard, for example.

The protection of trans­mis­sion can only be achieved by using encryption. Encryption means that the data is disguised so much by a process agreed beforehand that only the correct recipient can read it. The more compli­ca­ted the encryption process is, the better the protection of confi­den­tia­lity is.

Of course, there are always two partners who come to an agreement about the way of secret commu­ni­ca­tion. Therefore the respon­si­bi­lity for safe encyrption does not lie exclu­si­vely with the recipient of the message or exclu­si­ve­ly with the sender, but always with both of them. If you want to tell us something which should remain confi­den­tial, it is possible from our side outwards, but it depends upon the security of your software, namely your browser. Data protection is always also self-protection.

What is SSL?

SSL (Secure Socket Layer) is a protocol, which the American company Netscape developed and is used in most browsers. It lends itself to a safe server to client connection. Roughly simplified SSL does the following:

First of all, the computer to which you would like to send the data is authen­ti­ca­ted by a certi­fi­cate. You can also authen­ti­cate yourself (this is possible with SSL) but that is not really necessary. You can stay anonymous (and in most cases you are anonymous). Then your computer enters into dialogue with the partner computer in order to come to an agreement regarding the encryption process and the code. When this is finalised, the actual data is trans­fer­red encrypted in both directions.

All this happens unnoticed in modern browsers and you do not really have to do anything.

Is SSL safe?

This question cannot be answered straight­for­wardly. SSL is only a procedure of how two partner computers to commu­ni­cate safely. How they now commu­ni­cate largely depends on which encryption method both computers know and how complex the agreed code is.

Encryption methods are already built into your browser (if it under­stands SSL). Due to export constraints in the United States, however, older browsers' encryp­tion capabi­li­ties are insuf­fi­cient. It is therefore important that you use a newer browser. (Netscape Version 4.74 or later, MS Internet Explorer Version 5.5 or later, Opera 3.5, Konqueror 1.0).
