Right of data portability

You have the right to get in a machine-readable form the data which we have processed on the basis of your consent or by fulfillment of a contract or you can have them delivered to a third party. If you want the direct transmission of the data to another person responsible, this will be done when technically feasible.

SSL or TLS encryption

This page uses an SSL or TSL encryption for security reasons and to protect the transmission of confidential contents, like for example orders or requests which you send us as website operator. An encrypted connection can be recognized by the address line of the browser changing from http:// to https:// and by the lock icon in the browser line. Once the SSL or TSL encryption is activated, the data which you transmit cannot be read by third parties.

Within the framework of the current legal regulations you have at any time the right of free information regarding your stored personalized data, regarding their origin and receiver and the purpose of data processing and if applicable a right of correction, blocking or deletion of these data.

Data collection on our website


The websites use partly so-called cookies. The cookies do not cause any damage on your computer and do not contain viruses. Cookies serve the purpose of making our offer user-friendly, effective and safer. Cookies are simply small text files stored on the computer. Most of the cookies used by us are so-called „session cookies“ which are deleted immediately after the end of your visit. Other cookies remain on your computer until you delete them. These cookies allow us to recognize your browser as soon as you visit the website again. You can set your browser to alert you of cookies before receiving them and allow cookies only on a case by case basis, exclude the acceptance of cookies  for specific cases or generally and activate the automatic deletion of cookies when closing the browser. The functionality of our website might be restricted when deactivating cookies.

Cookies that are necessary to carry out electronic communication processes or to provide certain required functions (for example shopping cart function), will be stored on the basis of art. 6 paragraph 1 lit.f DSGVO. The website operator has a legitimate interest on the storage of cookies for the technically correct and optimized supply of his services. Insofar as other cookies (for example to analyse your surfing behaviour) are stored, the latter will be dealt with separately in this data protection declaration.

Server log files

The service provider of the pages collects and automatically stores information in so-called server log files that your browser sends to us automatically. These are:

browser type and browser version

used operating system

referrer URL

host name of the accessing computer

Time of the server inquiry

IP address

A combination of these data with other data sources is not carried out.

The basis for data processing is art. 6 paragraph 1 lit. b DSGVO which allows the processing of data to fulfill a contract or pre-contractual measures.

Contact form

When you send us requests per contact form, your information from the contact form including all the details will be stored by us for the purpose of processing your request and for follow-up questions. These data will not be passed on without your consent. The processing of the data mentioned in the contact form happens exclusively on the basis of your consent (art. 6 paragr. 1 lit. a DSGVO). You may revoke your consent at any time by sending us an e-mail. The legality of the data processing operations up to the revocation remains  unaffected by the revocation. Your data from the contact form remain with us unless you request deletion, revoke your consent to the storage or the purpose for data storage does not apply (for example after a completed processing of your request). Mandatory legal provisions – in particular retention periods – remain unaffected.

Right of modification

Zisska & Lacher Buch- und Kunstauktionshaus GmbH & Co. KG reserves the right to change at any time this declaration to data protection in compliance with the legal requirements.
