Relevant legal bases

Relevant legal bases under the GDPR: Below you will find an overview of the legal bases of the GDPR on the basis of which we process personal data. Please note that in addition to the provisions of the GDPR, national data protection regulations may apply in your or our country of residence or domicile. Should more specific legal bases also apply in individual cases, we will inform you of these in the privacy policy.

• Consent (Art. 6 para. 1 sentence 1 lit. a) GDPR) - The data subject has given their consent to the processing of their personal data for one or more specific purposes.
• Performance of a contract and pre-contractual inquiries (Art. 6 para. 1 sentence 1 lit. b) GDPR) - Processing is necessary for the performance of a contract to which the data subject is party or in order to take steps at the request of the data subject prior to entering into a contract.
• Legal obligation (Art. 6 para. 1 sentence 1 lit. c) GDPR) - Processing is necessary for compliance with a legal obligation to which the controller is subject.
• Legitimate interests (Art. 6 para. 1 sentence 1 lit. f) GDPR) - Processing is necessary for the purposes of the legitimate interests pursued by the controller or by a third party, except where such interests are overridden by the interests or fundamental rights and freedoms of the data subject which require protection of personal data.

National data protection regulations in Austria: In addition to the data protection regulations of the GDPR, national data protection regulations apply in Austria. These include, in particular, the Federal Act on the Protection of Natural Persons with regard to the Processing of Personal Data (Data Protection Act - DSG). In particular, the Data Protection Act contains special regulations on the right to information, the right to rectification or erasure, the processing of special categories of personal data, processing for other purposes and transfer as well as automated decision-making in individual cases.

Note on the applicability of the GDPR and Swiss FADP: This data protection notice serves to provide information in accordance with both the Swiss Federal Act on Data Protection (FADP) and the General Data Protection Regulation (GDPR). For this reason, please note that the terms of the GDPR are used due to the broader geographical application and comprehensibility. In particular, instead of the terms “processing” of “personal data”, “overriding interest” and “sensitive personal data” used in the Swiss DPA, the terms “processing” of “personal data”, “legitimate interest” and “special categories of data” used in the GDPR are used. However, the legal meaning of the terms will continue to be determined in accordance with the Swiss DPA within the scope of application of the Swiss DPA.

Security measures

We take appropriate technical and organizational measures in accordance with the legal requirements, taking into account the state of the art, the implementation costs and the nature, scope, circumstances and purposes of the processing as well as the different probabilities of occurrence and the extent of the threat to the rights and freedoms of natural persons, in order to ensure a level of protection appropriate to the risk.

The measures include, in particular, safeguarding the confidentiality, integrity and availability of data by controlling physical and electronic access to the data as well as the access, input, disclosure, safeguarding of availability and its separation. Furthermore, we have established procedures that ensure the exercise of data subject rights, the deletion of data and responses to data threats. Furthermore, we already take the protection of personal data into account during the development or selection of hardware, software and processes in accordance with the principle of data protection, through technology design and through data protection-friendly default settings.

Shortening of the IP address: If IP addresses are processed by us or by the service providers and technologies used and the processing of a full IP address is not required, the IP address is truncated (also known as “IP masking”). The last two digits or the last part of the IP address after a dot are removed or replaced by placeholders. The purpose of shortening the IP address is to prevent or make it much more difficult to identify a person by their IP address.

TLS encryption (https): We use TLS encryption to protect your data transmitted via our online offering. You can recognize such encrypted connections by the prefix https:// in the address bar of your browser.

Rights of the data subjects

Rights of data subjects under the GDPR: As a data subject, you are entitled to various rights under the GDPR, which arise in particular from Art. 15 to 21 GDPR:

• Right to object: You have the right to object, on grounds relating to your particular situation, at any time to processing of personal data concerning you which is based on Art. 6 para. 1 lit. e or f GDPR; this also applies to profiling based on these provisions. If the personal data concerning you are processed for direct marketing purposes, you have the right to object at any time to the processing of personal data concerning you for such marketing, which includes profiling to the extent that it is related to such direct marketing.
• Right to withdraw consent: You have the right to withdraw your consent at any time.
• Right of access: You have the right to obtain confirmation as to whether or not personal data concerning you is being processed and to obtain information about this data and further information and a copy of the data in accordance with the legal requirements.
• Right to rectification: In accordance with the statutory provisions, you have the right to request the completion of data concerning you or the rectification of inaccurate data concerning you.
• Right to erasure and restriction of processing: In accordance with the statutory provisions, you have the right to demand that data concerning you be erased immediately or, alternatively, to demand that the processing of the data be restricted in accordance with the statutory provisions.
• Right to data portability: You have the right to receive the data concerning you, which you have provided to us, in a structured, commonly used and machine-readable format in accordance with the legal requirements or to request its transmission to another controller.
• Complaint to a supervisory authority: In accordance with the statutory provisions and without prejudice to any other administrative or judicial remedy, you also have the right to lodge a complaint with a data protection supervisory authority, in particular a supervisory authority in the Member State in which you are habitually resident, the supervisory authority of your place of work or the place of the alleged infringement, if you consider that the processing of personal data relating to you infringes the GDPR.

Use of cookies

Cookies are small text files or other storage notes that store information on end devices and read information from the end devices. For example, to store the login status in a user account, the contents of a shopping cart in an e-shop, the content accessed or the functions used in an online offering. Cookies can also be used for various purposes, e.g. to ensure the functionality, security and convenience of online services and to analyze visitor flows.

Notes on consent: We use cookies in accordance with the statutory provisions. We therefore obtain prior consent from users, unless this is not required by law. In particular, consent is not required if the storage and reading of information, including cookies, is absolutely necessary in order to provide the user with a telemedia service expressly requested by them (i.e. our online offer). Strictly necessary cookies generally include cookies with functions that serve the display and operability of the online service, load balancing, security, storage of user preferences and selection options or similar purposes related to the provision of the main and secondary functions of the online service requested by the user. The revocable consent is clearly communicated to the users and contains the information on the respective use of cookies.

Information on legal bases under data protection law: The legal basis under data protection law on which we process users’ personal data with the help of cookies depends on whether we ask users for their consent. If users give their consent, the legal basis for processing their data is the consent given. Otherwise, the data processed with the help of cookies is processed on the basis of our legitimate interests (e.g. in the business operation of our online offering and improving its usability) or, if this is done in the context of fulfilling our contractual obligations, if the use of cookies is necessary to fulfill our contractual obligations. We explain the purposes for which we process cookies in the course of this privacy policy or as part of our consent and processing procedures.

Storage period: With regard to the storage period, a distinction is made between the following types of cookies:

• Temporary cookies (also: session cookies): Temporary cookies are deleted at the latest after a user has left an online service and closed their end device (e.g. browser or mobile application).
• Permanent cookies: Permanent cookies remain stored even after the end device is closed. For example, the login status can be saved or preferred content can be displayed directly when the user visits a website again. The user data collected with the help of cookies can also be used to measure reach. If we do not provide users with explicit information on the type and storage duration of cookies (e.g. when obtaining consent), users should assume that cookies are permanent and can be stored for up to two years.

General information on revocation and objection (so-called “opt-out”): Users can revoke the consent they have given at any time and object to processing in accordance with the legal requirements. Among other things, users can restrict the use of cookies in their browser settings (although this may also restrict the functionality of our online offering). An objection to the use of cookies for online marketing purposes can also be declared via the websites https://optout.aboutads.info and https://www.youronlinechoices.com/.

• Legal basis: Legitimate interests (Art. 6 para. 1 sentence 1 lit. f) GDPR). Consent (Art. 6(1) sentence 1 lit. a GDPR).

Further information on processing operations, procedures and services:

• Processing of cookie data on the basis of consent: We use a cookie consent management procedure in which the consent of users to the use of cookies or the processing and providers mentioned in the cookie consent management procedure can be obtained, managed and revoked by users. The declaration of consent is stored so that it does not have to be requested again and the consent can be proven in accordance with the legal obligation. Consent can be stored on the server and/or in a cookie (so-called opt-in cookie or with the help of comparable technologies) in order to be able to assign the consent to a user or their device. Subject to individual information on the providers of cookie management services, the following information applies: Consent may be stored for up to two years. A pseudonymous user identifier is created and stored with the time of consent, information on the scope of consent (e.g. which categories of cookies and/or service providers) as well as the browser, system and end device used; legal basis: consent (Art. 6 para. 1 sentence 1 lit. a) GDPR).

Business services

We process data of our contractual and business partners, e.g. customers and interested parties (collectively referred to as “contractual partners”) in the context of contractual and comparable legal relationships and associated measures and in the context of communication with the contractual partners (or pre-contractual), e.g. to answer inquiries.

We process this data in order to fulfill our contractual obligations. These include, in particular, the obligations to provide the agreed services, any updating obligations and remedies in the event of warranty and other service disruptions. In addition, we process the data to safeguard our rights and for the purpose of the administrative tasks associated with these obligations and the company organization. In addition, we process the data on the basis of our legitimate interests in proper and efficient business management and in security measures to protect our contractual partners and our business operations from misuse, threats to their data, secrets, information and rights (e.g. for the involvement of telecommunications, transport and other auxiliary services as well as subcontractors, banks, tax and legal advisors, payment service providers or tax authorities). Within the framework of applicable law, we only pass on the data of contractual partners to third parties to the extent that this is necessary for the aforementioned purposes or to fulfill legal obligations. Contractual partners will be informed about other forms of processing, e.g. for marketing purposes, as part of this privacy policy.

We inform the contractual partners which data is required for the aforementioned purposes before or as part of the data collection, e.g. in online forms, by special marking (e.g. colors) or symbols (e.g. asterisks or similar), or personally.

We delete the data after the expiry of statutory warranty and comparable obligations, i.e. generally after 4 years, unless the data is stored in a customer account, e.g. as long as it must be retained for legal archiving reasons. The statutory retention period is ten years for documents relevant under tax law as well as for trading books, inventories, opening balance sheets, annual financial statements, the work instructions required to understand these documents and other organizational documents and accounting records, and six years for commercial and business letters received and reproductions of commercial and business letters sent. The period begins at the end of the calendar year in which the last entry was made in the book, the inventory, the opening balance sheet, the annual financial statements or the management report was prepared, the commercial or business letter was received or sent or the accounting document was created, the record was made or the other documents were created.

Single sign-on” or “single sign-on registration or authentication” refers to procedures that allow users to log in to a provider of single sign-on procedures (e.g. a social network), including our online offering, with the help of a user account. The prerequisite for single sign-on authentication is that users are registered with the respective single sign-on provider and enter the required access data in the online form provided for this purpose, or are already registered with the single sign-on provider and confirm the single sign-on registration via a button.

Authentication takes place directly with the respective single sign-on provider. As part of such authentication, we receive a user ID with the information that the user is logged in to the respective single sign-on provider under this user ID and an ID that cannot be used by us for other purposes (so-called “user handle”). Whether additional data is transmitted to us depends solely on the single sign-on procedure used, on the data releases selected during authentication and also on which data users have released in the privacy or other settings of the user account with the single sign-on provider. Depending on the single sign-on provider and the user’s choice, it can be different data, usually the e-mail address and the user name. The password entered with the single sign-on provider as part of the single sign-on procedure is neither visible to us nor is it stored by us.

Users are asked to note that their details stored with us can be automatically compared with their user account with the single sign-on provider, but that this is not always possible or actually takes place. If, for example, users’ e-mail addresses change, they must change them manually in their user account with us.

If agreed with the users, we can use single sign-on registration in the context of or before the fulfillment of the contract, insofar as the users have been asked to do so, process it within the scope of consent and otherwise use it on the basis of our legitimate interests and the interests of the users in an effective and secure registration system.

Should users ever decide that they no longer wish to use the link to their user account with the single sign-on provider for the single sign-on procedure, they must cancel this link within their user account with the single sign-on provider. If users wish to delete their data with us, they must cancel their registration with us.

• Comments and posts: When users leave comments or other contributions, their IP addresses may be stored on the basis of our legitimate interests. This is done for our security in case someone leaves illegal content in comments and posts (insults, prohibited political propaganda, etc.). In this case, we ourselves can be prosecuted for the comment or post and are therefore interested in the identity of the author. Furthermore, we reserve the right to process user information for the purpose of spam detection based on our legitimate interests. On the same legal basis, we reserve the right to store the IP addresses of users for the duration of surveys and to use cookies to prevent multiple votes.

Chatbots and chat functions

We offer online chats and chatbot functions (collectively referred to as “chat services”) as a means of communication. A chat is an online conversation conducted with a certain degree of timeliness. A chatbot is software that answers users’ questions or informs them about messages. If you use our chat functions, we may process your personal data.

If you use our chat services within an online platform, your identification number will also be stored within the respective platform. We may also collect information about which users interact with our chat services and when. Furthermore, we store the content of your conversations via the chat services and log registration and consent processes in order to be able to prove these in accordance with legal requirements.

We would like to point out to users that the respective platform provider may find out that and when users communicate with our chat services and may collect technical information about the user’s device and, depending on the settings of their device, location information (so-called metadata) for the purpose of optimizing the respective services and for security purposes. Likewise, the metadata of communication via chat services (i.e., e.g., information about who has communicated with whom) may be used by the respective platform providers for marketing purposes or to display advertising tailored to users in accordance with their provisions, to which we refer for further information.

If users declare their willingness to a chatbot to activate information with regular messages, they have the option to unsubscribe from the information for the future at any time. The chatbot informs users how and with which terms they can unsubscribe from the messages. By unsubscribing from the chatbot messages, user data is deleted from the list of message recipients.

We use the aforementioned data to operate our chat services, e.g. to address users personally, to answer their queries, to transmit any requested content and also to improve our chat services (e.g. to “teach” chatbots answers to frequently asked questions or to recognize unanswered queries).

Notes on legal bases: We use chat services on the basis of consent if we have previously obtained users’ permission for the processing of their data within the scope of our chat services (this applies in cases where users are asked for consent, for example so that a chatbot can regularly send them messages). If we use chat services to respond to user inquiries about our services or our company, this is done for contractual and pre-contractual communication. Otherwise, we use chat services on the basis of our legitimate interests in optimizing the chat services, improving their economic efficiency, and enhancing the positive user experience.

Withdrawal, objection, and deletion: You can withdraw your consent at any time or object to the processing of your data within the scope of our chat services.

• Processed Data: Contact data (e.g., email, telephone numbers); content data (e.g., entries in online forms); usage data (e.g., visited websites, interest in content, access times); meta, communication, and procedural data (e.g., IP addresses, timestamps, identification numbers, consent status).

Push messages

With the user’s consent, we can send users so-called “push notifications”. These are messages that are displayed on users’ screens, end devices or browsers, even if our online service is not currently being actively used.

In order to register for the push messages, users must confirm the request from their browser or end device to receive the push messages. This consent process is documented and saved. The storage is necessary to recognize whether users have agreed to receive the push messages and to be able to prove their consent. For these purposes, a pseudonymous identifier of the browser (so-called “push token”) or the device ID of an end device is stored.

Push notifications may be necessary for the fulfilment of contractual obligations (e.g. technical and organizational information relevant to the use of our online offer) and are otherwise sent on the basis of the user’s consent, unless specifically mentioned below. Users can change the receipt of push messages at any time using the notification settings of their respective browsers or end devices.

Cloud services

We use software services accessible via the Internet and running on the servers of their providers (so-called “cloud services”, also referred to as “software as a service”) for the storage and management of content (e.g. document storage and management, exchange of documents, content and information with specific recipients or publication of content and information).

In this context, personal data may be processed and stored on the provider’s servers if they are part of communication processes with us or are otherwise processed by us as set out in this privacy policy. This data may include, in particular, master data and contact data of users, data on transactions, contracts, other processes and their content. Cloud service providers also process usage data and metadata that they use for security purposes and to optimize their services.

If we use cloud services to provide other users or publicly accessible websites with forms or other documents and content, the providers may store cookies on users’ devices for the purposes of web analysis or to remember user settings (e.g. in the case of media control).

• Data processed: Inventory data (e.g., names, addresses); contact data (e.g., email, phone numbers); content data (e.g., entries in online forms); usage data (e.g., websites visited, interest in content, access times). Meta, communication, and process data (e.g., IP addresses, time stamps, identification numbers, consent status).

Web analysis, monitoring and optimization

Web analysis (also referred to as “reach measurement”) is used to evaluate the flow of visitors to our online offering and may include behavior, interests or demographic information about visitors, such as age or gender, as pseudonymous values. With the help of reach analysis, we can, for example, recognize at what time our online offer or its functions or content are most frequently used or invite reuse. We can also understand which areas require optimization.

In addition to web analysis, we may also use test procedures, e.g. to test and optimize different versions of our online offering or its components.

Unless otherwise stated below, profiles, i.e. data summarized for a usage process, can be created for these purposes and information can be stored in a browser or in an end device and read out from it. The information collected includes, in particular, websites visited and the elements used there as well as technical information such as the browser used, the computer system used and information on usage times. If users have consented to the collection of their location data from us or from the providers of the services we use, location data may also be processed.

IP addresses of users are also stored. However, we use an IP masking procedure (i.e. pseudonymization by shortening the IP address) to protect users. In general, no clear user data (such as e-mail addresses or names) is stored in the context of web analysis, A/B testing and optimization, but pseudonyms. This means that neither we nor the providers of the software used know the actual identity of the users, but only the information stored in their profiles for the purposes of the respective processes.

• Types of data processed: Usage data (e.g., visited websites, interest in content, access times); meta, communication, and procedural data (e.g., IP addresses, timestamps, identification numbers, consent status).
• Affected persons: Users (e.g., website visitors, users of online services).
• Purpose of processing: Reach measurement (e.g., access statistics, identification of returning visitors). Profiles with user-related information (creation of user profiles).
• Security measures: IP masking (pseudonymization of IP address).
• Legal bases: Consent (Art. 6(1) sentence 1 lit. a GDPR).

Presence in social networks (social media)

We maintain online presences within social networks and process user data in this context in order to communicate with the users active there or to offer information about us.

We would like to point out that user data may be processed outside the European Union. This may result in risks for users because, for example, it could make it more difficult to enforce users’ rights.

Furthermore, user data within social networks is generally processed for market research and advertising purposes. For example, user profiles can be created based on user behavior and the resulting interests of users. The user profiles can in turn be used, for example, to place advertisements within and outside the networks that presumably correspond to the interests of the users. For these purposes, cookies are generally stored on the user’s computer, in which the user’s usage behavior and interests are stored. Furthermore, data can also be stored in the user profiles independently of the devices used by the users (especially if the users are members of the respective platforms and are logged in to them).

For a detailed description of the respective forms of processing and the opt-out options, please refer to the data protection declarations and information provided by the operators of the respective networks.

In the case of requests for information and the assertion of data subject rights, we would also like to point out that these can be asserted most effectively with the providers. Only the providers have access to the users’ data and can take appropriate measures and provide information directly. If you still need help, you can contact us.

Plugins and embedded functions and content

We incorporate functional and content elements into our online offering that are obtained from the servers of their respective providers (hereinafter referred to as “third-party providers”). These may be, for example, graphics, videos or city maps (hereinafter uniformly referred to as “content”).

The integration always requires that the third-party providers of this content process the IP address of the user, as they would not be able to send the content to their browser without the IP address. The IP address is therefore required to display this content or function. We endeavor to only use content whose respective providers only use the IP address to deliver the content. Third-party providers may also use so-called pixel tags (invisible graphics, also known as “web beacons”) for statistical or marketing purposes. Pixel tags can be used to analyze information such as visitor traffic on the pages of this website. The pseudonymous information may also be stored in cookies on the user’s device and may contain, among other things, technical information about the browser and operating system, referring websites, time of visit and other information about the use of our online offer, as well as being linked to such information from other sources.
