You can generally visit our websites without telling us who you are. Our web servers automatically store information of a general nature. This includes the type of web browser, the operating system used, the domain name of your Internet service provider, the website from which you visit us, the websites you visit with us, and the date and duration of your visit. This is only information that does not allow conclusions to be drawn about yourself. We evaluate this data only for statistical purposes and only in anonymous form. The collection and use of personal data of our users takes place regularly only with the consent of the user. An exception applies in cases where prior consent is not possible for factual reasons and the processing of the data is permitted by legal regulations.

2. Legal basis for the processing of personal data
For processing of personal data, we obtain the consent of the data subject. The legal basis for processing is Article 6 (1) lit b of the GDPR.

In the event that vital interests of the data subject or another natural person require the processing of personal data, the legal basis for processing is Article 6 (1) lit b of the GDPR.
If the processing is necessary to safeguard the legitimate interests of our company or a third party and the interests, fundamental rights and freedoms of the person concerned do not outweigh the first interest, Article 6 (1) lit f, shall apply, according the GDPR as the legal basis for processing.

3. Data erasure and storage
As soon as the purpose of the storage is not needed anymore, personal data of the data subject will be deleted or blocked. Storage may also take place if this has been provided for by the European or national legislator in EU regulations, laws or other regulations to which the controller is subject. The data shall also be blocked or deleted if a storage period prescribed by the above-mentioned standards expires, unless there is a need for further storage of the data for the conclusion of a contract or a performance of the contract.

4. Obligation to provide data

As part of our contractual relationship, you must provide the personal data that is necessary for the establishment and execution of the accommodation contract or which we are legally obliged to collect. Without this data, we will generally not be able to conclude or execute the contract with you. In particular, we are obliged to collect certain personal data about you within the scope of the registration certificate in accordance with Section 30 (3) of the Federal Registration Act. If you do not provide us with the necessary information, we may not be able to provide the services you require or may not be able to provide them in full.

In the event of an objection, your personal data will no longer be processed unless we can prove compelling legitimate grounds for the processing that outweigh your interests, rights and freedoms, or the processing serves the purpose of the Assertion, exercise and defense of legal claims. If we process your personal data for direct marketing, you have the right to object at any time to the processing of personal data concerning you for the purpose of such advertising; this also applies to profiling insofar as it is related to such direct marketing.

The revocation can be made via the relevant link in any e-mail newsletter or by e-mail with the subject "Unsubscribe" to marketing@prinzregent.de.
