Data protection­statement

Data protection

The operator of this website takes the protection of your personal data very seriously. We handle your personal data
confidentially and in line with statutory data protection legislation as well as this data protection statement. It is generally possible to use our website without providing personal data. If personal data are provided on our website (for example names, addresses or email addresses), this is always done on a voluntary basis, as far as
possible. These data will not be passed to third parties without your express consent. We would like to point out that data transmission via the internet (e.g. when communicating by email) can be subject to security gaps. It is not possible to completely protect data from being accessed through third parties.


The webpages use so-called cookies at times. Cookies do not cause any damage to your computer and do not contain viruses. Cookies allow us to make our web offer more user-friendly, effective and safe. Cookies are small text files which are placed on your computer and saved by your browser. Most of the cookies used by us are so-called “session cookies”. They will be automatically deleted at the end of your visit
. Other cookies remain saved on your device until you delete them.
These cookies allow us to recognise your browser at the next visit. You can set your browser so that you are informed about the setting of cookies and allow cookies only in individual cases, exclude the acceptance of cookies for certain cases or in general and activate the automatic deletion of cookies when closing the browser. Deactivating cookies may restrict the functionality of this website.

IP anonymisation

We have activated the IP anonymisation function on this website. This causes your IP address to be truncated by Google within member states of the European Union or in other signatory states to the Agreement on the European Economic Area prior to transmission to the USA. Only in exceptional cases is the full IP address transferred to a Google server in the USA and shortened there. On behalf of the operator of this website, Google will use this information for the purpose of evaluating your use of the website, compiling reports on website activity and providing other services relating to website activity and
internet use to the website operator. The IP address transmitted by your browser as part of Google Analytics is not merged with other data from Google.

Demographic features at Google Analytics

This website uses the function “demographic features” by Google Analytics. This means reports can be produced including statements on the age, gender and interests of the visitors to the website. These data are derived from interest-based advertising by Google and from visitor data from third parties. These data cannot be assigned to a specific person. You can deactivate this function at any time via the ad settings in your Google Account or generally prohibit the collection of your data by Google Analytics as described in the section “Objection to data collection”.

Google Web Fonts

This site uses so-called web fonts, which are provided by Google, for the uniform display of fonts. When you load a page, your browser loads the required web fonts in its browser cache to display texts and fonts. If your browser does not support web fonts, your computer will use a standard font. You can find more information about Google web fonts at https://developers.google.com/fonts/faq and in
Google’s privacy policy: https://www.google.com/policies/privacy/

Google Maps

This website uses the map service Google Maps via an API. The provider is Google Inc., 1600 Amphitheatre Parkway Mountain View, CA 94043, USA. In order to use the functions of Google Maps, you need to save your IP address. This information is generally transmitted to a Google server in the USA and saved there. The provider of this website has no influence on this data transfer.

Our website uses plugins from YouTube, which is operated by Google. The operator of the webpages is YouTube, LLC, 901 Cherry Ave., San Bruno, CA 94066, USA. If you visit one of our webpages which is equipped with a YouTube plugin, a connection to the YouTube services is created. The YouTube server is thereby informed which of our webpages you have visited. If you are logged into your YouTube account, you are allowing YouTube to relate your surfing activity directly to your personal profile. You can prevent this by logging out of your YouTube account. You can find more information on handling user data in YouTube’s privacy policy at: https://www.google.de/intl/de/policies/privacy

Userlike Live-Chat Plugin

When you load the live chat, AIHE will initially collect your IP address for a short period in order to determine the country from which you are starting the live chat. This makes it possible for us to offer you customer services tailored to your needs. The IP address is collected for this purpose only and is not permanently stored by AIHE. AIHE also saves the live chats. This serves the purpose of saving you the need for extensive explanations about the history of your request as well as the ongoing quality control of our live chat service. If you do not wish to do so, you are welcome to let us know using the contact details listed below or in the legal notice. Saved live chats will then be deleted by us immediately. You can find more information about the privacy policy of the provider of this plugin at: https://www.userlike.com/de/terms#privacy-policy

SSL encryption

This site uses SSL encryption for security reasons and to protect the transmission of confidential content, such as the requests you send to us as site operator. You can recognise an encrypted connection when the address line of the browser changes from “http://” to “https://” and from the locked symbol in the browser line. If SSL encryption is activated, the data you transmit to us cannot be read by third parties.

Contact forms

If you send us enquiries via the contact form, your details from the enquiry form including the contact data you provide there will be stored by us for the purpose of processing the enquiry and in the event of follow-up questions. We will not pass these data on without your consent. The processing of the data entered in the contact form is thus exclusively based on your consent (Art. 6 (1)(a) GDPR). You can revoke this consent at any time. Simply send us an email informing us of this. The legality of the data processing operations carried out up to the point of revocation remains unaffected by the revocation. The data you enter in the contact form will remain with us until you request us to delete it, revoke your consent for storage or the purpose for which the data were stored no longer applies (e.g. after your enquiry has been processed). Mandatory statutory provisions – in particular retention periods – remain unaffected.

Information, Deletion, Blocking

Many methods of processing data are only possible with your express consent. You have the right to receive information free of charge at any time about your stored personal data, its origin and recipients and the purpose of data processing as well as the right to correct, block or delete these data. For this purpose, as well as for further questions on the subject of personal data, you can contact us at any time at the website operator’s address given in the legal notice. All you have to do is send us an email or use the online services of this website:
Please follow the link for further information about deleting your data with the possibility of an online deletion request and automatic deletion. You can make an online request for information about your personal data here. The legality of the data processing carried out until the point of revocation remains unaffected by the revocation.

Right to data transferability

You have the right to have data, which we process automatically on the basis of your consent or in fulfilment of a contract, provided to you or to a third party in a common, machine-readable format. If you request the direct transfer of the data to another responsible person, this will only be done where it is technically feasible.
