Relevant Legal Bases

Relevant legal bases under the GDPR: Below you will find an overview of the legal bases of the GDPR on 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 establishment. If more specific legal bases apply in individual cases, we will inform you of these in this privacy policy.

• Performance of a contract and pre-contractual inquiries (Art. 6(1)(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(1)(c) GDPR) – Processing is necessary for compliance with a legal obligation to which the controller is subject.
• Legitimate interests (Art. 6(1)(f) GDPR) – Processing is necessary for the purposes of the legitimate interests pursued by the controller or by a third party, provided that such interests are not overridden by the interests or fundamental rights and freedoms of the data subject which require protection of personal data.

National data protection regulations in Germany: In addition to the GDPR, national data protection regulations apply in Germany. This includes, in particular, the Federal Data Protection Act (Bundesdatenschutzgesetz – BDSG). The BDSG contains specific provisions on the right of access, the right to erasure, the right to object, the processing of special categories of personal data, processing for other purposes and transmission, as well as automated individual decision-making including profiling. Furthermore, data protection laws of the individual federal states may apply.

Security Measures

We take appropriate technical and organizational measures in accordance with legal requirements, taking into account the state of the art, implementation costs, and the nature, scope, context and purposes of processing, as well as the varying likelihood and severity of risks to the rights and freedoms of natural persons, to ensure a level of security appropriate to the risk.

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 related access, input, transfer, ensuring availability and separation of the data. In addition, we have established procedures to ensure the exercise of data subject rights, the deletion of data, and responses to threats to the data. Furthermore, we take into account the protection of personal data already during the development or selection of hardware, software and procedures, in accordance with the principle of data protection through technology design and by data protection-friendly default settings.

Securing online connections through TLS/SSL encryption technology (HTTPS): To protect users’ data transmitted via our online services from unauthorized access, we use TLS/SSL encryption technology. Secure Sockets Layer (SSL) and Transport Layer Security (TLS) are the cornerstones of secure data transmission on the internet. These technologies encrypt the information transmitted between the website or app and the user’s browser (or between two servers), thereby protecting the data from unauthorized access. TLS, as the more advanced and secure version of SSL, ensures that all data transmissions meet the highest security standards. When a website is secured by an SSL/TLS certificate, this is indicated by the display of HTTPS in the URL. This serves as an indicator to users that their data is transmitted securely and in encrypted form.

General Information on Data Storage and Deletion

We delete personal data that we process in accordance with legal requirements as soon as the underlying consents are revoked or there are no other legal grounds for processing. This applies in cases where the original purpose of processing ceases to apply or the data is no longer needed. Exceptions to this rule exist if statutory obligations or special interests require longer retention or archiving of the data.

In particular, data that must be retained for commercial or tax reasons, or whose storage is necessary for the prosecution of rights or for the protection of the rights of other natural or legal persons, must be archived accordingly.

Our privacy notices contain additional information on the retention and deletion of data that apply specifically to certain processing operations.

If multiple retention periods or deletion deadlines are specified for a dataset, the longest period shall always apply. Data that is no longer retained for the original purpose but is kept due to legal requirements or other reasons is processed solely for the reasons that justify its retention.

Retention and deletion of data: The following general periods apply to retention and archiving under German law:

• 10 years – Retention period for books and records, annual financial statements, inventories, management reports, opening balance sheet as well as work instructions and other organizational documents necessary for their understanding (§ 147(1) no. 1 in conjunction with (3) AO, § 14b(1) UStG, § 257(1) no. 1 in conjunction with (4) HGB).
• 8 years – Accounting records such as invoices and cost receipts (§ 147(1) nos. 4 and 4a in conjunction with (3) sentence 1 AO and § 257(1) no. 4 in conjunction with (4) HGB).
• 6 years – Other business documents: incoming commercial or business letters, copies of outgoing commercial or business letters, other documents insofar as they are relevant for taxation, e.g., hourly wage slips, cost accounting sheets, calculation documents, price markings, as well as payroll documents insofar as they are not already accounting records, and cash register strips (§ 147(1) nos. 2, 3, 5 in conjunction with (3) AO, § 257(1) nos. 2 and 3 in conjunction with (4) HGB).
• 3 years – Data required to take into account potential warranty and damages claims or similar contractual claims and rights, as well as to process related inquiries, based on previous business experience and common industry practice, is stored for the duration of the regular statutory limitation period of three years (§§ 195, 199 BGB).

Start of the period at the end of the year: If a period does not explicitly begin on a specific date and is at least one year, it automatically starts at the end of the calendar year in which the event triggering the period occurred. In the case of ongoing contractual relationships in which data is stored, the triggering event is the effective date of the termination or other ending of the legal relationship.

Rights of Data Subjects

Rights of data subjects under the GDPR: As data subjects, you have various rights under the GDPR, in particular those arising from Articles 15 to 21 GDPR:

• Right to object: You have the right, on grounds relating to your particular situation, to object at any time to the processing of personal data concerning you which is based on Article 6(1)(e) or (f) GDPR; this also applies to profiling based on those provisions. Where personal data concerning you is processed for direct marketing purposes, you have the right to object at any time to processing of personal data concerning you for such marketing; this also applies to profiling to the extent that it is related to such direct marketing.
• Right to withdraw consent: You have the right to withdraw consents given 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, where that is the case, access to the personal data as well as further information and a copy of the data in accordance with legal requirements.
• Right to rectification: In accordance with legal requirements, 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 legal requirements, you have the right to request that data concerning you be erased without undue delay, or alternatively to request restriction of processing of the data in accordance with legal requirements.
• 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, or to request its transmission to another controller, in accordance with legal requirements.
• Right to lodge a complaint with a supervisory authority: Without prejudice to any other administrative or judicial remedy, you have the right to lodge a complaint with a supervisory authority, in particular in the Member State of your habitual residence, 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.

Payment Procedures

In the context of contractual and other legal relationships, due to legal obligations, or otherwise on the basis of our legitimate interests, we offer the data subjects efficient and secure payment options and use additional service providers for this purpose, in addition to banks and credit institutions (collectively “payment service providers”).

The data processed by the payment service providers include inventory data, such as name and address, bank details such as account numbers or credit card numbers, passwords, TANs and checksums, as well as contract-, amount- and recipient-related information. The information is required in order to carry out the transactions. However, the entered data is processed only by the payment service providers and stored there. That is, we do not receive any account or credit card-related information, but only information with confirmation or negative notification of the payment. Under certain circumstances, the payment service providers transmit the data to credit agencies. This transmission is intended for identity and credit checks. For this purpose, we refer to the T&Cs and the privacy notices of the payment service providers.

For payment transactions, the terms and conditions and the privacy notices of the respective payment service providers apply, which can be accessed within the respective websites or transaction applications. We also refer to these for further information and the assertion of rights of withdrawal, access and other rights of data subjects.

Single Sign-On Login

“Single Sign-On” or “Single Sign-On login/authentication” refers to procedures that allow users to log in to our online offer using an account with a Single Sign-On provider (e.g., a social network). A prerequisite for Single Sign-On authentication is that users are registered with the respective Single Sign-On provider and enter the required login data in the form provided, or are already logged in with the Single Sign-On provider and confirm the Single Sign-On login via 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 with the respective Single Sign-On provider under this user ID and an ID that cannot be further 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 release choices made 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 users’ choices, various data may be involved; as a rule, this is the email address and the username. The password entered in the context of the Single Sign-On procedure with the Single Sign-On provider is neither visible to us nor stored by us.

Users are asked to note that their details stored with us can be automatically matched with their user account at the Single Sign-On provider, but this is not always possible or actually carried out. If, for example, users’ email addresses change, they must change them manually in their user account with us.

We may use Single Sign-On login, if agreed with users, in the context of or prior to contract performance, process it insofar as users have requested it within the framework of consent, and otherwise use it on the basis of our legitimate interests and those of the users in an effective and secure login system.

If users decide that they no longer wish to use the link between their user account with the Single Sign-On provider for the Single Sign-On procedure, they must remove this connection within their user account with the Single Sign-On provider. If users wish to have their data deleted with us, they must cancel their registration with us.

• Employees: “Employees” are persons who are in an employment relationship, whether as staff, salaried employees or in similar positions. An employment relationship is a legal relationship between an employer and an employee, established by an employment contract or agreement. It includes the employer’s obligation to pay remuneration while the employee performs their work. The employment relationship includes various phases, such as establishment, in which the employment contract is concluded, execution, in which the employee performs work, and termination, when the employment relationship ends, whether by dismissal, termination agreement or otherwise. Employee data is all information relating to these persons and within the context of their employment. This includes aspects such as personal identification data, identification numbers, salary and bank data, working hours, vacation entitlements, health data and performance evaluations.
• Inventory data: Inventory data includes essential information necessary for the identification and management of contractual partners, user accounts, profiles and similar assignments. These data may include, among other things, personal and demographic information such as names, contact information (addresses, telephone numbers, email addresses), dates of birth and specific identifiers (user IDs). Inventory data forms the basis for any formal interaction between individuals and services, institutions or systems by enabling unambiguous assignment and communication.
• Content data: Content data includes information generated in the course of creating, editing and publishing content of all kinds. This category of data may include texts, images, videos, audio files and other multimedia content published on various platforms and media. Content data is not limited to the content itself but also includes metadata that provides information about the content, such as tags, descriptions, author information and publication dates.

Metadata, also known as data about data, includes information that describes the context, origin and structure of other data. It may include details such as file size, creation date, the author of a document and change histories. Communication data records the exchange of information between users across various channels, such as email traffic, call logs, messages on social networks and chat histories, including the persons involved, timestamps and transmission paths.
