3. Collection of general data and information

The website of the City of Jena collects a series of general data and information each time the website is accessed by a data subject or an automated system. This general data and information is stored in the server log files. The following can be recorded
(1) browser types and versions used,
(2) the operating system used by the accessing system
(3) the website from which an accessing system reaches the municipal website (so-called referrer)
(4) the sub-websites which are accessed via an accessing system on the municipal website
(5) the date and time of access to the website
(6) an internet protocol address (IP address),
(7) the internet service provider of the accessing system and
(8) other similar data and information used for security purposes in the event of attacks on the city's information technology systems.

When using this general data and information, the City of Jena does not draw any conclusions about the data subject. The data stored in the log files is not stored together with other personal data of the user.
The legal basis for the temporary storage of data and log files is Art. 6 para. 1 lit. f GDPR.
This information is required in order to
(1) correctly deliver the content of the municipal website
(2) optimize the content of the municipal website and the advertising for it
(3) ensure the long-term functionality of the city's information technology systems and the technology of the website, and

Therefore, the City of Jena analyzes anonymously collected data and information statistically, with the aim of increasing the data protection and data security of the City of Jena, and to ensure an optimal level of protection for the personal data processed by the City of Jena. The data is not analyzed for marketing purposes in this context.
The data is deleted as soon as it is no longer required to achieve the purpose for which it was collected. In the case of the collection of data for the provision of the website, this is the case when the respective session has ended. Data may be stored beyond this point. In this case, the IP addresses of the users are deleted or anonymized so that it is no longer possible to identify the accessing client.
The collection of data for the provision of the website and the storage of data in log files is absolutely necessary for the operation of the website. Consequently, the user has no option to object.

4. Cookies

The Internet pages of the City of Jena use cookies. Cookies are text files that are placed and stored on a computer system via an internet browser.
Numerous websites and servers use cookies. Many cookies contain a so-called cookie ID. A cookie ID is a unique identifier of the cookie. It consists of a string of characters that can be used to assign websites and servers to the specific internet browser in which the cookie was stored. This enables the websites and servers visited to distinguish the individual browser of the data subject from other Internet browsers that contain other cookies. A specific Internet browser can be recognized and identified via the unique cookie ID.
Through the use of cookies, the City of Jena can provide the users of this website with more user-friendly services that would not be possible without the cookie setting.
By means of a cookie, the information and offers on the website can be optimized for the benefit of the user. For example, the user of a website that uses cookies does not have to re-enter their access data each time they visit the website because this is taken over by the website and the cookie stored on the user's computer system.
The data subject may, at any time, prevent the setting of cookies through the municipal website by means of a corresponding setting of the Internet browser used, and may thus permanently deny the setting of cookies. Furthermore, cookies that have already been set can be deleted at any time via an Internet browser or other software programs. This is possible in all common Internet browsers. If the data subject deactivates the setting of cookies in the Internet browser used, not all functions of the website may be fully usable.
The legal basis for the processing of personal data using cookies is Art. 6 para. 1 lit. f GDPR.

5. Registration on the website

The data subject has the option of registering on the controller's website by providing personal data. Which personal data is transmitted to the controller is determined by the respective input mask used for registration. The personal data entered by the data subject is collected and stored exclusively for internal use by the controller and for the controller's own purposes. The controller may arrange for the data to be passed on to one or more processors, such as a parcel service provider, who will also use the personal data exclusively for internal use attributable to the controller.
By registering on the controller's website, the IP address assigned by the data subject's Internet service provider (ISP), the date and time of registration are also stored. This data is stored against the background that this is the only way to prevent misuse of the services offered and, if necessary, to enable criminal offenses to be investigated. This data is not passed on to third parties unless there is a legal obligation to pass it on or it serves the purpose of criminal prosecution.
The registration of the data subject by providing personal data serves the controller to offer the data subject content or services which, due to the nature of the matter, can only be offered to registered users. Registered persons are free to change the personal data provided during registration at any time or to have it completely deleted from the controller's database.
The controller shall provide any data subject at any time upon request with information about which personal data relating to the data subject is stored. Furthermore, the controller shall rectify or erase personal data at the request or indication of the data subject, insofar as this does not conflict with any statutory retention obligations. All of the controller's employees are available to the data subject as contact persons in this context.

6. Contact option via the website

Due to legal regulations, the website of the City of Jena contains information that enables quick electronic contact and direct communication, which also includes a general address for so-called electronic mail (e-mail address). If a data subject contacts the controller by email or via a contact form, the personal data transmitted by the data subject will be stored automatically. Such personal data transmitted on a voluntary basis by a data subject to the controller are stored for the purposes of processing or contacting the data subject. This personal data is not passed on to third parties.

9. Data protection provisions about the application and use of Matomo

The data controller has integrated the Matomo component on this website. Matomo is an open source software tool for web analysis. Web analysis is the collection, gathering and evaluation of data about the behavior of visitors to websites. Among other things, a web analysis tool collects data on the website from which a data subject came to a website (so-called referrer), which subpages of the website were accessed or how often and for how long a subpage was viewed.
Web analysis is mainly used to optimize a website and for the cost-benefit analysis of Internet advertising.
The software is operated on the server of the controller, and the log files, which are sensitive under data protection law, are stored exclusively on this server.
The purpose of the Matomo component is to analyze the flow of visitors to this website. The controller uses the data and information obtained, among other things, to evaluate the use of this website in order to compile online reports that show the activities on the municipal websites. This helps to continuously improve the website and its user-friendliness. These purposes also constitute the legitimate interest in the processing of data in accordance with Art. 6 para. 1 lit. f GDPR. By anonymizing the IP address, the interest of users in the protection of their personal data is adequately taken into account.
Matomo places a cookie on the data subject's IT system. What cookies are has already been explained above. By setting the cookie, the city of Jena is able to analyze the use of the city's website. Each time one of the individual pages of this website is accessed, the Internet browser on the information technology system of the data subject is automatically prompted by the Matomo component to transmit data to our server for the purpose of online analysis. As part of this technical process, we obtain knowledge of personal data, such as the IP address of the data subject, which serves us, among other things, to trace the origin of visitors and clicks.
Cookies are used to store personal information, such as the access time, the location from which access was made and the frequency of visits to our website. Each time you visit our website, this personal data, including the IP address of the internet connection used by the data subject, is transmitted to our server. This personal data is stored by us. This personal data is not passed on to third parties.
The software is set so that the IP addresses are not stored in full, but 2 bytes of the IP address are masked (e.g.: 192.168.xxx.xxx). In this way, it is no longer possible to assign the shortened IP address to the accessing computer.
The data subject may, as stated above, prevent the setting of cookies through the municipal website at any time by means of a corresponding adjustment of the web browser used and thus permanently deny the setting of cookies. Such a setting of the Internet browser used would also prevent Matomo from setting a cookie on the information technology system of the person concerned. In addition, a cookie already set by Matomo can be deleted at any time via an Internet browser or other software programs.
Furthermore, the data subject has the possibility of objecting to and preventing the collection of data generated by Matomo relating to the use of this website. To do this, the data subject must set an opt-out cookie. If the data subject's IT system is deleted, formatted or reinstalled at a later date, the data subject must set an opt-out cookie again.
With the setting of the opt-out cookie, however, there is the possibility that the Internet pages of the controller are no longer fully usable for the data subject.
A "cookie request" is made when the ksj.jena.de page is accessed. Matomo can be deactivated here. Matomo can be subsequently deactivated via the homepage ksj.jena.de in the lower area under "Customize data protection settings".
Further information and the applicable data protection provisions of Matomo can be found at https://matomo.org/privacy/

10. Legal basis for processing

Insofar as the consent of the data subject is obtained for the processing of personal data, Art. 6 para. 1 lit. a EU General Data Protection Regulation (GDPR) serves as the legal basis.
When processing personal data that is necessary for the performance of a contract to which the data subject is a party, Art. 6 para. 1 lit. b GDPR serves as the legal basis. This also applies to processing operations that are necessary to carry out pre-contractual measures.
Insofar as the processing of personal data is necessary to fulfill a legal obligation to which the City of Jena is subject, Art. 6 para. 1 lit. c GDPR serves as the legal basis.
In the event that vital interests of the data subject or another natural person require the processing of personal data, Art. 6 para. 1 lit. d GDPR serves as the legal basis.
In the event that the processing of personal data is necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the City of Jena, Art. 6 para. 1 lit. e GDPR serves as the legal basis for the processing.
If the processing is necessary to safeguard a legitimate interest of the City of Jena or a third party and if the interests, fundamental rights and freedoms of the data subject do not outweigh the first-mentioned interest, Art. 6 para. 1 lit. f GDPR serves as the legal basis for the processing.

11. Legal or contractual provisions for the provision of personal data; necessity for the conclusion of the contract; obligation of the data subject to provide the personal data; possible consequences of non-provision

The provision of personal data is partly required by law (e.g. tax regulations) or can also result from contractual regulations (e.g. information on the contractual partner). Sometimes it may be necessary for a contract to be concluded for a data subject to provide personal data that must subsequently be processed by the city. For example, the data subject is obliged to provide personal data if the city concludes a contract with them. Failure to provide the personal data would mean that the contract with the data subject could not be concluded. Prior to the provision of personal data by the data subject, the data subject must contact the city. The data subject will then be informed on a case-by-case basis whether the provision of the personal data is required by law or contract or is necessary for the conclusion of the contract, whether there is an obligation to provide the personal data and what the consequences would be if the personal data were not provided.

12. Existence of automated decision-making

The City of Jena does not use automated decision-making or profiling.

13. Use of services of Google Inc.

The following Google Inc. services are used on this website:

  • Integration of videos from YouTube
    When integrating YouTube videos, the extended data protection mode offered by Google is used, in which no cookies are stored before an integrated YouTube video is played.
    Further information and the applicable data protection provisions of Google Inc. can be found at https://policies.google.com/privacy

14. Social networks

The City of Jena takes the current discussion about data protection in social networks very seriously. It is currently not legally clear whether and to what extent all social networks offer their services in accordance with European data protection regulations.
It is therefore expressly pointed out that the Twitter, Facebook, Xing, Google+ and YouTube services used by the City of Jena store the data of their users (e.g. personal information, IP address) in accordance with their data usage guidelines and use it for business purposes. The City of Jena has no influence on the data collection and its further use by the social networks. For example, there is no knowledge of the extent to which, where and for how long the data is stored, the extent to which the networks comply with existing deletion obligations, which evaluations and links are made with the data and to whom the data is passed on.

15. Right to lodge a complaint with a supervisory authority

Without prejudice to any other administrative or judicial remedy, you have the right to lodge a complaint with a supervisory authority, in particular in the Member State of your habitual residence, place of work or place of the alleged infringement if you consider that the processing of personal data relating to you infringes the GDPR.
The supervisory authority with which the complaint has been lodged shall inform the complainant on the progress and the outcome of the complaint including the possibility of a judicial remedy pursuant to Art. 78 GDPR.

16. Links

Our website contains links to other websites. We have no influence on whether their operators comply with data protection regulations. This privacy policy applies exclusively to data collected on this website. However, please note the disclaimer in our legal notice.

17. Updating the privacy policy

The rapid development of the Internet makes it necessary to adapt this privacy policy from time to time. You will be informed about the changes here, so we recommend that you visit this website regularly so that you are kept up to date about the protection and processing of your data.
