We shall treat your personal data as confidential and in accordance with the statutory data protection regulations as well as this privacy policy. The fundamental legal basis is the European General Data Protection Regulation (GDPR) and other national data protection acts. Transferred personal data shall only be stored for as long as necessary to use the service in question on the website

Your personal data shall only be processed and used outside of the service where necessary for the fulfilment of the duties incumbent on the city or where required by law. The data shall not be shared with private institutions or bodies. Please note that the transfer of information over the Internet is not completely secure. The possibility that third parties might intercept or modify the data you transfer cannot be ruled out.

Other data are collected by our IT systems automatically when you visit the website. This primarily concerns technical data (e.g. your Internet browser, operating system or the time of your visit to the page). These data are collected automatically as soon as you visit our website.

Some of the data are collected to ensure that the website is provided with zero errors. Other data can be used to analyse how you use the website.

What rights do you have with regard to your data?
You have the right to request free information about the origins, recipients and purposes of stored personal data concerning you at any time.

Withdrawing your consent to data processing

Many data processing procedures require your express consent. You can withdraw consent that you have already granted at any time. If you wish to do so, simply send us an e-mail. A withdrawal of consent does not retroactively affect the lawfulness of data processing that has taken place up to the moment of withdrawal.

Right to lodge a complaint with a supervisory authority

In the event of a breach of the data protection regulations, you, the data subject, are entitled to lodge a complaint with the relevant supervisory authority. The supervisory authority responsible for matters relating to data protection is the Federal Data Protection Commissioner for the state in which our company has its registered office.

Right to data portability

You are entitled to receive data which we are processing by automated means on the basis of your consent or in order to execute a contract and are entitled to have those data transmitted to a third party in a commonly used and machine-readable format. If you ask for the data to be transmitted directly to another controller, this shall only be carried out where technically feasible.

SSL and TLS encryption

For security reasons and in order to protect the transfer of confidential content such as orders or enquiries which you send to us, the operator of the website, this page uses SSL and TLS encryption. You can tell that a connection is encrypted when the address bar in your browser changes from “http://” to “https://” and from the padlock symbol in your address bar. When SSL and TLS encryption is active, the data you send to us cannot be read by third parties.

Description and scope of data processing

Whenever you visit our website, our system automatically collects data and information from your computer.

The following data are collected:

  1. Information about your browser type and version

  8. Point (f) of Article 6 (1) GDPR serves as the legal grounds for the temporary storage of the data and for the log files.

The temporary storage of an IP address by the system is necessary for the purpose of transmitting the website to your computer. Your IP address has to be stored for the duration of the session. It is stored in log files to guarantee the functionality of the website. Additionally, the data enable us to optimise the website and ensure the security of our IT systems. The data are not evaluated for marketing purposes in this context.

We also have a legitimate interest in data processing for these purposes in accordance with point (f) of Article 6 (1) GDPR. The data are erased as soon as they are no longer necessary for the achievement of the purpose for which they were collected. If the data have been collected in order to make the website available, they will be deleted when the session ends. If the data have been stored in log files, they will be deleted within no more than four weeks. They can be stored for longer. In this case, your IP addresses will be deleted or anonymised in order to prevent them from being associated with the visiting client.

The collection of the data in order to make the website available and the storage of the data in log files is absolutely necessary for the operation of the website. Therefore, you have no right to object.

No images can be broadcast outside of these hours.


Contact form and e-mail correspondence

Our website features a contact form that can be used to contact us electronically. If you make use of the form, the data entered in the contact form will be transmitted to us and stored. These data are as follows:

Point (f) of Article 6 (1) GDPR serves as the legal grounds for the processing of data transmitted as part of sending an e-mail. If the e-mail correspondence is aimed towards concluding a contract, point (b) of Article 6 (1) GDPR serves as additional legal grounds for processing. Processing the personal data from the form only serves to process the correspondence. If we are contacted by e-mail, we also have a necessary legitimate interest in the processing of the data.

The conversation will be considered ended when the circumstances imply that the matter in question has been resolved.

You can revoke your consent to the processing of personal data at any time. If you contact us by e-mail, you can object to the storage of personal data concerning you at any time. In this case, the conversation cannot be continued.


Integration of services and third-party content



In line with our legitimate interests (i.e. our interest in the analysis, optimisation and economical operation of our website in the sense of point (f) of Article 6 (1) GDPR), we use content and services from third-party providers on our website in order to integrate their content and services. The City of Frankfurt/Main has created a channel on the video portal YouTube at uses plugins from the platform YouTube which is provided by Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA. When you visit one of our pages that features a YouTube plugin, a connection is established with the Google servers. The provider sends the content of the plugin directly to your browser which embeds it into the page. By embedding the plug-in, Google is notified that your browser has accessed the page on the website even if you do not have a profile with a Google service or are currently not logged in. This information (your IP address) is transferred from your browser to a Google server in the USA and stored there. See here for more information on data protection at Google: Privacy policy:, Opt-out:


We embed maps from the service OpenStreetMap ( which are provided by the OpenStreetMap Foundation on the basis of the Open Data Commons Open Database Licence. To our knowledge, OpenStreetMap only uses user data for the purposes of displaying the map features and temporarily storing chosen settings. In particular, these data can include your IP address and location data, although such data cannot be collected without your consent (this is normally provided through the settings of your mobile device). 

The data can be processed in the USA. More information is available in the privacy policy of OpenStreetMap at


MainMAP+ saves the information you have saved in mainMAP+ in your independently created account. Your e-mail address, your username and the password you have chosen are stored in encrypted form in the database. In addition, the message IDs of the messages you have explicitly saved and the time at which you may wish to receive a newsletter are saved.
In order to avoid a third-party entry, each new account must be activated separately by you personally using a confirmation link.

You can revoke the use of your mainMAP+ at any time by clicking on the corresponding link in the confirmation email "Delete profile", or by deleting your account in mainMAP+ under "Settings".

Use of cookies

a) In the maps application

Our website uses text files known as cookies to store data on your computer which are necessary for the website to function fully. The cookie contains references to the traffic information you have chosen to display. We use cookies:

in our maps application and
the mainMAP.
Furthermore, no unique personal data are collected. These stored data are browser-exclusive; this means they are only stored on the device and in the browser with which you are using our website. Under certain circumstances, elements of your operating system to which we have no access might transfer the data to other devices. 

If you do not want cookies to be used, you can restrict or completely deactivate them in the settings of your browser. Doing so will result in the following disruptions on When you use the maps application under “Traffic information”, the layers you select will not be stored and will therefore not be pre-selected if you visit again later. Additionally, the report ID stores what reports you have stored in your mainMap. This will no longer work when you visit the mainMap again and will render this service unusable.

b) Matomo analytics service

Additionally, our website uses cookies to analyse the surfing habits of users. This is a web analytics service provided by Matomo (formerly Piwik), an open-source software tool. Matomo uses cookies which are text files that are stored on your computer and enable us to analyse how you use the website. For this purpose, the usage information generated by the cookie (including your truncated IP address) is transferred to our server and stored for usage analysis for the purpose of optimising our website. The following data are stored:

One byte from the IP address of the system used to access the website

  1. The visited website
  2. The website you were on previously (i.e. the referrer)
  3. The pages visited on the visited website
  4. The time spent on the website
  5. The frequency of visits to the website

As your IP address is anonymised immediately in this process (Automatically Anonymise Visitor IPs), you will remain anonymous to us as a user. The IP address shall be truncated to one byte. For more information, visit

This means that it is no longer possible to attribute the data to the user who is visiting the website. The software runs on the server of our website exclusively. The data are not stored together with other personal data belonging to users. The information on your use of the website generated by the cookie is not shared with third parties.

As the user, you have full control over the use of cookies. You can change the settings in your browser to deactivate or limit the transfer of cookies at any time. Cookies that are already on your computer can be deleted at any time.

When you visit our website, a cookie banner will notify you that cookies are being used for analytical purposes and refer you to this privacy policy. In this regard, you can also prevent the installation of cookies by changing the settings in your browser software. However, if you choose to do so, you might be unable to make full use of all of the features of this website.

If you do not consent to the storage and analysis of the data generated by your visit, you can object to the storage and use of the data at any time at the click of a mouse as follows. In this case, an opt-out cookie which will prevent Matomo from collecting any session data will be installed in your browser. Warning: If you erase your cookies, the opt-out cookie will be erased too and you will need to activate it again.  

The personal data of users are processed on the basis of point (f) of Article 6 (1) GDPR. Processing the personal data of users enables us to analyse the surfing habits of our users. By analysing the data we collect, we are able to compile information about how the individual components of our website are used. This helps us to improve our website and its user-friendliness on a continuous basis.

We also have a legitimate interest in processing the data for these purposes in accordance with point (f) of Article 6 (1) GDPR. IP address anonymisation takes the user’s interest in the protection of his or her personal data into account sufficiently. The data shall be erased when they are no longer needed for the purposes for which we collected them. On our part, this is the case after two years.
