Access data (server log files)

When you visit our website, we automatically collect and store access data in so-called server log files, which your browser automatically transmits to us.
This includes:

• Browser type and browser version of your PC
• Operating system used by your PC
• Date and time of the server request
• As a rule, it is not possible for us to identify individuals, nor is this our intention. Such data is processed in accordance with Art. 6 (1) lit. f GDPR to safeguard our legitimate interest in improving the stability and functionality of our website.

Cookies

We use so-called cookies to make visiting our website attractive and to enable the use of certain functions. These are small text files that are stored on your device. Cookies cannot execute programs or transfer viruses to your computer system.

Cookies that are necessary for the electronic communication process or to provide certain functions you have requested are stored on the basis of Art. 6 (1) lit. f GDPR. We have a legitimate interest in storing cookies for the technically error-free and optimized provision of our services. If other cookies (e.g., cookies for analyzing your surfing behavior) are stored, these are treated separately in this privacy policy.

Most of the cookies we use are so-called “session cookies.” They are automatically deleted at the end of your visit. Other cookies remain stored on your device until you delete them. These cookies enable us to recognize your browser the next time you visit.
You can set your browser so that you are informed about the setting of cookies and only allow cookies 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. If you deactivate cookies, the functionality of this website may be limited.

Web analysis tools and advertising

Google Analytics

Our website uses the web analysis service Google Analytics in the version Google Analytics 4. The provider is Google Ireland Ltd., Gordon House, Barrow Street, Dublin 4, Ireland (“Google”).

Google Analytics uses so-called “cookies.” These are text files that are stored on your computer and enable an analysis of your use of our website. In Google Analytics, all data from devices located in the EU (based on the geographical location according to the IP address) is collected via domains and servers in the EU before the traffic is forwarded to Analytics servers for processing.

The legal basis for the processing of your data is the consent you have given via the cookie consent tool in accordance with Art. 6 (1) sentence 1 lit. a) GDPR.

IP anonymization

The IP anonymization feature is automatically activated on the website in Google Analytics. This means that your IP address will be truncated by Google within member states of the EU or in other signatory states to the Agreement on the European Economic Area before being transmitted to the US. Only in exceptional cases will the full IP address be transmitted to a Google server in the US and truncated there. On our behalf, Google will use this information to evaluate your use of our website, to compile reports on website activity, and to provide us with other services related to website activity and internet usage. According to Google, IP addresses are not logged and stored in Google Analytics, but are only processed briefly for geolocation and deleted immediately afterwards. The IP address transmitted by your browser as part of Google Analytics is not merged with other Google data.

Order processing

We have concluded a contract with Google for order processing and fully implement the strict requirements of the German data protection authorities when using Google Analytics.

Storage period

Data stored by Google at user and event level that is linked to cookies, user IDs (e.g., user ID) or advertising IDs (e.g., DoubleClick cookies, Android advertising ID) is deleted after two months. Details can be found at the following link: https://support.google.com/analytics/answer/7667196?hl=de.

Right of withdrawal

Many data processing operations are only possible with your express consent. If the processing of your data is based on your consent, you have the right to withdraw your consent to the processing of data at any time with effect for the future in accordance with Art. 7 (3) GDPR by accessing the cookie settings and changing your selection there. The revocation of consent does not affect the lawfulness of the processing carried out on the basis of the consent until revocation. The storage of data for billing and accounting purposes remains unaffected by a revocation.

For more information on how Google Analytics handles user data, please refer to Google’s privacy policy: https://support.google.com/analytics/answer/6004245?hl=de.

Further information on data protection can be found in Google’s privacy policy: https://policies.google.com/privacy?hl=de&gl=de

Google Maps

Our website uses the Google Maps map service provided by Google Ireland Ltd., Gordon House, Barrow Street, Dublin 4, Ireland (“Google”) via an API (Application Programming Interface).
To ensure data protection on our website, Google Maps is deactivated when you first visit our website. A direct connection to Google’s servers is only established when you activate Google Maps yourself (consent in accordance with Art. 6 (1) (a) GDPR). This prevents your data from being transferred to Google when you first visit our website.
After activation, Google Maps will store your IP address. This is then usually transferred to a Google server in the USA and stored there. The provider of this site has no influence on this data transfer after Google Maps has been activated.
For more information on how user data is handled, please refer to Google’s privacy policy: https://www.google.de/intl/de/policies/privacy/.

Contact form

If you contact us by email or via a contact form, the data transmitted, including your contact details, will be stored so that we can process your enquiry or be available for follow-up questions. This data will not be passed on without your consent.
The data entered in the contact form will be processed exclusively on the basis of your consent (Art. 6 (1) (a) GDPR). You can revoke your consent at any time. An informal email is sufficient for revocation. The legality of the data processing operations carried out until revocation remains unaffected by the revocation.

Data transmitted via the contact form will remain with us until you request its deletion, revoke your consent to its storage, or there is no longer any need for data storage. Mandatory legal provisions—in particular retention periods—remain unaffected.

Data use and disclosure

We will not sell or otherwise market to third parties the personal data that you provide to us, e.g. by email (e.g. your name and address or your email address). Your personal data will only be processed for correspondence with you and only for the purpose for which you have provided us with the data.

The use of data that is automatically collected when you visit our website is only for the purposes mentioned above. The data will not be used for any other purpose.

We assure you that we will not disclose your personal data to third parties unless we are legally obliged to do so or you have given us your prior consent.

SSL or TLS encryption

For security reasons and to protect the transmission of confidential content, such as requests you send to us as the site operator, our website uses SSL or TLS encryption. You can recognize an encrypted connection by the fact that the address line of the browser changes from “http://” to “https://” and by the lock symbol in your browser line.
If SSL or TLS encryption is activated, the data you transmit to us cannot be read by third parties.

Storage period

Personal data provided to us via our website will only be stored until the purpose for which it was entrusted to us has been fulfilled. Insofar as commercial and tax law retention periods must be observed, the storage period for certain data may be up to 10 years.

Rights of data subjects

As a data subject, you have the following rights vis-à-vis the controller with regard to your personal data in accordance with the statutory provisions:

Right of withdrawal

Many data processing operations are only possible with your express consent. If the processing of your data is based on your consent, you have the right to withdraw your consent to the processing of data at any time with effect for the future in accordance with Art. 7 (3) GDPR. The revocation of consent does not affect the lawfulness of the processing carried out on the basis of the consent until revocation. The storage of data for billing and accounting purposes remains unaffected by a revocation.

Right to information

You have the right, in accordance with Art. 15 GDPR, to request confirmation from us as to whether we process personal data concerning you. If such processing is taking place, you have the right to obtain information about your personal data processed by us, the purposes of the processing, the categories of personal data processed, the recipients or categories of recipients to whom your data has been or will be disclosed, the planned storage period or the criteria for determining the storage period, the existence of a right to rectification, deletion, restriction of processing, objection to processing, complaint to a supervisory authority, the origin of your data if it was not collected by us from you, the existence of automated decision-making, including profiling, and, where applicable, meaningful information about the logic involved and the significance and intended effects of such processing on you, as well as your right to be informed of the guarantees that exist in accordance with Art. 46 GDPR when your data is transferred to third countries.

Right to rectification

You have the right, in accordance with Art. 16 GDPR, to request the immediate rectification of inaccurate personal data concerning you and/or the completion of your incomplete data at any time.

Right to erasure

You have the right, in accordance with Art. 17 GDPR, to request the erasure of your personal data if one of the following reasons applies:

• Your personal data is no longer necessary for the purposes for which it was collected or otherwise processed
• You withdraw your consent on which the processing was based in accordance with Art. 6 (1) (a) or Art. 9 (2) (a) GDPR, and there is no other legal basis for the processing
• You object to the processing pursuant to Art. 21 (1) GDPR and there are no overriding legitimate grounds for the processing, or you object to the processing pursuant to Art. 21 (2) GDPR
• The personal data has been processed unlawfully
• The erasure of the personal data is necessary to comply with a legal obligation under Union law or the law of the Member State to which we are subject
• The personal data has been collected in relation to information society services offered in accordance with Art. 8 (1) GDPR

However, this right does not apply if the processing is necessary:

• for exercising the right of freedom of expression and information
• for compliance with a legal obligation which requires processing under Union or Member State law to which we are subject, or for the performance of a task carried out in the public interest or in the exercise of official authority vested in us
• for reasons of public interest in the area of public health in accordance with Art. 9 (2) (h) and (i) and Art. 9 (3) GDPR
• for archiving purposes in the public interest, scientific or historical research purposes or statistical purposes pursuant to Art. 89(1) GDPR, insofar as the rights of the data subject are likely to render impossible or seriously impair the achievement of the objectives of this processing, or
• for the establishment, exercise or defense of legal claims.

If we have made your personal data public and are obliged to delete it in accordance with the above, we will take appropriate measures, including technical measures, taking into account the available technology and implementation costs, to inform data controllers who process the personal data that you, as the data subject, have requested the deletion of all links to your personal data or copies or replications of this personal data.

Right to restriction of processing

You have the right to request the restriction of processing (blocking) of your personal data in accordance with Art. 18 GDPR. To do so, you can contact us at any time at the address given in the imprint. The right to restriction of processing exists in the following cases:

• If you dispute the accuracy of your personal data stored by us, we usually need time to verify this. For the duration of the verification, you have the right to request the restriction of the processing of your personal data
• If the processing of your personal data was/is unlawful, you can request the restriction of data processing instead of deletion
• If we no longer need your personal data, but you need it to exercise, defend, or assert legal claims, you have the right to request the restriction of the processing of your personal data instead of deletion
• If you have lodged an objection pursuant to Art. 21 (1) GDPR, a balance must be struck between your interests and ours. As long as it is not yet clear whose interests prevail, you have the right to request the restriction of the processing of your personal data

If you have restricted the processing of your personal data, this data may – apart from its storage – only be processed with your consent or for the assertion, exercise, or defense of legal claims or for the protection of the rights of another natural or legal person or for reasons of important public interest of the EU or a member state.

Right to information

If you have asserted your right to rectification, erasure, or restriction of processing against us, we are obliged to notify all recipients to whom your personal data has been disclosed of this rectification, erasure, or restriction of processing, unless this proves impossible or involves disproportionate effort. Pursuant to Art. 19 GDPR, you have the right to be informed about these recipients upon request.

Right not to be subject to a decision based solely on automated processing, including profiling

Pursuant to Art. 22 GDPR, you have the right not to be subject to a decision based solely on automated processing, including profiling, which produces legal effects concerning you or similarly significantly affects you.

This does not apply if the decision

• is necessary for the conclusion or performance of a contract between you and us
• is authorised by Union or Member State law to which the controller is subject and which also lays down suitable measures to safeguard your rights and freedoms and legitimate interests, or
• is based on your explicit consent.

However, decisions in the cases referred to in (a) to (c) may not be based on special categories of personal data pursuant to Art. 9 (1) GDPR, unless Art. 9 (2) (a) or (g) applies and appropriate measures have been taken to protect your rights and freedoms and your legitimate interests.

In the cases referred to in (a) and (c), we take appropriate measures to safeguard your rights and freedoms and your legitimate interests, including at least the right to obtain human intervention on the part of the controller, to express your point of view and to contest the decision.

Right to data portability

If the processing is based on your consent pursuant to Art. 6 para. 1 lit. a GDPR or Art. 9 para. 2 lit. a GDPR or on a contract pursuant to Art. 6 para. 1 lit. b GDPR and is carried out using automated procedures, you have the right, pursuant to Art. 20 GDPR to receive your personal data that you have provided to us in a structured, commonly used, and machine-readable format and to transmit it to another controller or to request its transmission to another controller, insofar as this is technically feasible.

Right to object

Insofar as we base the processing of your personal data on the balancing of interests pursuant to Art. 6 (1) lit. f GDPR, you have the right to object to the processing of your personal data at any time for reasons arising from your particular situation; this also applies to profiling based on this provision. The respective legal basis on which processing is based can be found in this privacy policy. If you object, we will no longer process your personal data unless we can demonstrate compelling legitimate grounds for the processing that override your interests, rights, and freedoms, or the processing serves to assert, exercise, or defend legal claims (objection pursuant to Art. 21(1) GDPR).

If your personal data is processed for direct marketing purposes, you have the right to object at any time to the processing of personal data concerning you for the purpose of such marketing; this also applies to profiling insofar as it is related to such direct marketing. If you object, your personal data will no longer be used for direct marketing purposes (objection pursuant to Art. 21 (2) GDPR).

You have the option, in connection with the use of information society services – notwithstanding Directive 2002/58/EC – to exercise your right to object by means of automated procedures using technical specifications.

Right to lodge a complaint with the competent supervisory authority pursuant to Art. 77 GDPR

In the event of violations of the GDPR, data subjects have the right to lodge a complaint with a supervisory authority, in particular in the Member State of their habitual residence, place of work, or place of the alleged violation. The right to lodge a complaint exists without prejudice to other administrative or judicial remedies.

The supervisory authority responsible for us is:

The State Commissioner for Data Protection of Lower Saxony
Prinzenstraße 5
30159 Hanover
