2. General Information on Data Processing

2.1. Relevant Legal Bases

Below you will find an overview of the legal bases under 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 country or our country of residence or domicile.

Consent (Art. 6 (1) sentence 1 lit. a) GDPR) – The data subject has given consent to the processing of their personal data for one or more specific purposes.
Performance of a contract and pre-contractual requests (Art. 6 (1) sentence 1 lit. b) GDPR) – Processing is necessary for the performance of a contract to which the data subject is a party or in order to take steps at the request of the data subject prior to entering into a contract.
Legitimate interests (Art. 6 (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.

In addition to the data protection rules of the GDPR, national data protection regulations apply in Germany, in particular the Federal Data Protection Act (BDSG) and the Act on Data Protection and the Protection of Privacy in Telecommunications and Telemedia (TDDDG).

2.2. Security Measures

We take appropriate technical and organisational measures in accordance with the legal requirements, taking into account the state of the art, the cost of implementation, and the nature, scope, circumstances, and purposes of the processing as well as the varying probability of occurrence and severity of the risk 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 through control of physical and electronic access to the data, as well as the access, input, transfer, availability, and segregation of data.

Securing online connections via TLS/SSL encryption technology (HTTPS): To protect the data of users transmitted via our online services from unauthorised access, we use TLS/SSL encryption technology. Where a website is secured by an SSL/TLS certificate, this is signalled by the display of HTTPS in the URL.

2.3. International Data Transfers

Where we transfer data to a third country (i.e. outside the European Union (EU) or the European Economic Area (EEA)) or where this occurs in the context of using third-party services, this is always carried out in accordance with the legal requirements.

For data transfers to the USA, we rely primarily on the Data Privacy Framework (DPF), which was recognised as a secure legal framework by an adequacy decision of the EU Commission of 10 July 2023. In addition, we have concluded standard contractual clauses with the respective providers, which comply with the requirements of the EU Commission.

For each individual service provider, we inform you whether they are certified under the DPF and whether standard contractual clauses are in place. Further information on the DPF can be found on the website of the U.S. Department of Commerce at https://www.dataprivacyframework.gov/.

2.4. Data Storage and Deletion

We delete personal data that we process in accordance with the legal provisions as soon as the underlying consents are revoked or no further legal bases for processing exist. This applies to cases in which the original purpose of processing no longer applies or the data is no longer needed.

Exceptions to this rule exist where statutory obligations or particular interests require longer retention or archiving of the data. In particular, data that must be retained for commercial or tax law reasons, or whose storage is necessary for the pursuit of legal claims or for the protection of the rights of other natural or legal persons, must be archived accordingly.

The following general retention and archiving periods apply under German law:

10 years – Retention period for books and records, annual financial statements, inventories, management reports, opening balance sheets, and the working instructions and other organisational documents required to understand them, as well as accounting vouchers and invoices (§ 147 (3) in conjunction with (1) nos. 1, 4 and 4a AO, § 14b (1) UStG, § 257 (1) nos. 1 and 4, (4) HGB).
6 years – Other business records: received commercial or business letters, copies of dispatched commercial or business letters, and other documents to the extent that they are relevant for taxation (§ 147 (3) in conjunction with (1) nos. 2, 3, 5 AO, § 257 (1) nos. 2 and 3, (4) HGB).
3 years – Data required to take into account potential warranty and damage claims or similar contractual claims and rights, as well as to handle related enquiries, based on prior business experience and customary industry practice, are stored for the duration of the regular statutory limitation period of three years (§§ 195, 199 BGB).

2.5. Rights of Data Subjects

As a data subject, you have various rights under the GDPR, which arise in particular from Art. 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 carried out on the basis of Art. 6 (1) lit. e or f GDPR; this also applies to profiling based on these provisions. If personal data concerning you is processed for direct marketing purposes, you have the right to object at any time to the processing of your personal data for the purpose of such marketing.
Right to withdraw consent: You have the right to withdraw consent given at any time.
Right of access: You have the right to request confirmation as to whether data concerning you is being processed and to obtain information about this data and further information as well as a copy of the data in accordance with the legal requirements.
Right to rectification: You have the right, in accordance with the legal requirements, to request the completion of data concerning you or the rectification of inaccurate data concerning you.
Right to erasure and restriction of processing: You have the right, in accordance with the legal requirements, to request that data concerning you be erased without undue delay, or alternatively, in accordance with the legal requirements, to request a restriction of the processing of the data.
Right to data portability: You have the right, in accordance with the legal requirements, to receive data concerning you that you have provided to us in a structured, commonly used, and machine-readable format, or to request its transmission to another controller.
Complaint to a supervisory authority: In accordance with the legal requirements 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 of your habitual residence, the supervisory authority of your place of work, or the place of the alleged infringement, if you consider that the processing of personal data concerning you infringes the GDPR.

3. Specific Information on Data Processing

3.1. Provision of the Online Offering and Web Hosting

We process the data of users in order to provide them with our online services. For this purpose, we process the user’s IP address, which is necessary in order to transmit the content and functions of our online services to the user’s browser or device.

Our website is built with the JavaScript framework Next.js and hosted on the cloud platform Vercel.

Collection of access data and log files: Access to our online offering is logged in the form of so-called “server log files”. Server log files may include the address and name of the web pages and files retrieved, the date and time of retrieval, the volume of data transferred, notification of successful retrieval, browser type and version, the user’s operating system, the referrer URL (the previously visited page), and as a rule IP addresses and the requesting provider. Server log files may be used for security purposes, e.g. to prevent overloading of the servers (in particular in the case of abusive attacks, so-called DDoS attacks), and to ensure server load and stability.

Types of data processed: Usage data (e.g. page views and time spent, click paths, device types and operating systems used); meta-, communication- and process data (e.g. IP addresses, time stamps, identification numbers); log data (e.g. log files relating to data retrieval or access times).
Data subjects: Users (e.g. website visitors).
Purposes of processing: Provision of our online offering and user-friendliness; information technology infrastructure; security measures.
Retention and deletion: Log file information is stored for a maximum period of 30 days and then deleted or anonymised. Data whose further retention is required for evidentiary purposes is exempt from deletion until the respective incident has been finally resolved.
Legal bases: Legitimate interests (Art. 6 (1) sentence 1 lit. f) GDPR).
