Relevant legal bases

Collaboration with contractor data processors and third parties

If, in the context of our processing, we disclose data to other persons and companies (contract processors or third parties), transmit them to such or otherwise grant access to the data, such disclosure or transmission is done exclusively on the basis of a legal permission (e.g. if a transmission of the data to third parties is required by payment service providers to fulfill the contract, pursuant to Art. 6 (1) (b) GDPR), because you have consented to the disclosure, because of a legal obligation or based on our legitimate interests (e.g. the use of agents, web hosters, etc.).

Cookies and right to object to direct mailing

"Cookies" are small files that are stored on users computers. Various information can be stored within the cookies. A cookie serves primarily to store the information about a user (or the device on which the cookie is stored) during or after his visit to an online service.

Temporary cookies, or "session cookies" or "transient cookies", are cookies that are deleted after a user leaves an online service and closes his browser. In such a cookie, e.g. the contents of a shopping cart are stored in an online store or a login status.

The term "permanent" or "persistent" refers to cookies that remain stored after the browser has been closed. In such cookies, e.g. the login status stays saved if users visit the site after several days. The interests of the users can also be stored in such cookies, and they can be used for range measurement or marketing purposes.

A "third-party cookie" refers to cookies that are used by providers other than the person responsible for managing the online service (Cookies used by the online service itself are called "first-party cookies").

We may use temporary and permanent cookies and clarify this in the context of our privacy policy.

If users do not want cookies to be stored on their computer, they are asked to disable the relevant option in their browser's system settings. Cookies already saved can be deleted in the system settings of the browser. The exclusion of cookies may lead to functional restrictions of this online service.

An explanation on general objection to the use of cookies used for online marketing purposes, especially in the case of tracking, can be obtained at a variety of services, , via the US website http://www.aboutads.info/choices/ or the EU site http://www.youronlinechoices.com/ be explained. Furthermore, the storage of cookies can be avoided by switching them off in the settings of the browser. Please note that not all features of this online service may be used if cookies are switched off.

Deletion of data

The data processed by us is deleted or limited in their processing in accordance with Articles 17 and 18 GDPR. Unless explicitly stated in this privacy policy, the data stored with us will be deleted as soon as it is no longer necessary for its intended purpose and its deletion does not conflict with any statutory retention requirements. If the data is deleted because it is required for other and legitimate purposes, its processing will be restricted. This means the data is locked and not processed for other purposes. This applies, e.g., to data that must be kept for commercial or tax reasons.

According to legal regulations in Austria relevant data is stored specifically for 7 years according to § 132 paragraph 1 BAO (accounting documents, receipts / invoices, accounts, receipts, business papers, statement of income and expenses, etc.), for 22 years in connection with real estate and for 10 years in the case of documents related to electronically supplied services, telecommunications, broadcasting and television services provided to non-EU companies in EU Member States to which the Mini-One-Stop-Shop (MOSS) is applied.


The hosting services we use serve to provide the following services: infrastructure and platform services, computing capacity, storage and database services, collateral and technical maintenance services, all of which we use to operate this online service.

In the course of this we, respectively our hosting provider, process inventory data, contact data, content data, contract data, usage data, meta and communication data of customers, interested parties and visitors to this online service on the basis of our legitimate interests in an efficient and secure provision of this online service according to Art. 6 para. 1 lit. f GDPR i.V.m.

Collection of access data and logfiles

Logfile information is stored for security reasons (e.g. to investigate abusive or fraudulent activities) for a maximum of 7 days and then deleted. Data the which of further retention is required for evidence purposes is excluded from the deletion until final clarification of the respective incident.

Registration function

If users have terminated their user account, their data will be deleted with regard to the user account, unless their retention is necessary for commercial or tax law reasons according to Art. 6 para. 1 lit. c GDPR.
It is the responsibility of the users to save their data upon termination before the end of the contract. We are entitled to irretrievably delete all user data stored during the contract period.

In the context of the use of our registration and login functions as well as the use of user accounts, we store the IP address and the time of the respective user action.
This storage is on the basis of our legitimate interests, as well as the user's protection against misuse and other unauthorized use.
