2. Data processing on this website
General information on the legal basis for data processing on this website
If you have consented to data processing, we will process your personal data based on Art. 6 (1) (a) GDPR or Art. 9 (2) (a) GDPR if special categories of data are processed under Art. 9 (1) GDPR. In the case of express consent to the transfer of personal data to third countries, data processing will also be based on Art. 49 (1) (a) GDPR. If you have consented to the storage of cookies or access to information on your device (e.g., via device fingerprinting), data processing will also be based on Section 25 (1) TDDDG. Your consent can be revoked at any time. If your data is required to fulfill the contract or to carry out pre-contractual measures, we will process your data based on Art. 6 (1) (b) GDPR. Furthermore, we process your data if it is necessary to fulfill a legal obligation based on Art. 6 (1) (c) GDPR. Data processing may also be based on our legitimate interest under Art. 6 (1) (f) GDPR. The relevant legal bases in each individual case are explained in the following paragraphs of this privacy policy.
Recipients of personal data
As part of our business activities, we work with various external parties. In some cases, this also requires the transfer of personal data to these external parties. We only transfer personal data to external parties if this is necessary to fulfill a contract, if we are legally obliged to do so (e.g., transferring data to tax authorities), if we have a legitimate interest in the transfer under Art. 6 (1) (f) GDPR, or if another legal basis permits the transfer. When using processors, we only transfer our customers' personal data based on a valid contract for order processing. In the case of joint processing, a joint processing contract is concluded.
SSL or TLS encryption
This site uses SSL or TLS encryption for security reasons and to protect the transmission of confidential content, such as orders or inquiries that you send to us as the site operator. You can recognize an encrypted connection by the browser's address bar changing from "http://" to "https://" and by the lock symbol in your browser's address bar.
If SSL or TLS encryption is enabled, the data you transmit to us cannot be read by third parties.
Server Log Files
The website provider automatically collects and stores information in so-called server log files, which your browser automatically transmits to us. These include:
• Browser type and version
• Operating system used
• Referrer URL
• Hostname of the accessing computer
• Time of the server request
• IP address
This data will not be merged with other data sources.
This data is collected based on Art. 6 (1) (f) GDPR. The website operator has a legitimate interest in the technically error-free presentation and optimization of its website – for this purpose, the server log files must be collected.
Contact form
If you send us inquiries via the contact form, your details from the inquiry form, including the contact details you provided there, will be stored by us to process your inquiry and in case of follow-up questions. We will not share this data without your consent.
This data is processed based on Art. 6 (1) (b) GDPR if your inquiry is related to the fulfillment of a contract or is necessary to carry out pre-contractual measures. In all other cases, the processing is based on our legitimate interest in the effective processing of inquiries addressed to us (Art. 6 (1) (f) GDPR) or on your consent (Art. 6 (1) (a) GDPR), if requested; consent can be revoked at any time.
The data you enter in the contact form will remain with us until you request its deletion, revoke your consent to storage, or the purpose for storing the data no longer applies (e.g., after your inquiry has been processed). Mandatory statutory provisions – in particular retention periods – remain unaffected.
Inquiry by email or telephone
If you contact us by email or telephone, your inquiry, including all personal data resulting from it (name, inquiry), will be stored and processed by us for the purpose of processing your request. We will not disclose this data without your consent.
This data will be processed based on Art. 6 (1) (b) GDPR if your inquiry is related to the fulfillment of a contract or is necessary to carry out pre-contractual measures. In all other cases, the processing is based on our legitimate interest in the effective processing of inquiries addressed to us (Art. 6 (1) (f) GDPR) or on your consent (Art. 6 (1) (a) GDPR), if requested; consent can be revoked at any time.
The data you send to us via contact inquiries will remain with us until you request deletion, revoke your consent to storage, or the purpose for storing the data no longer applies (e.g., after your request has been processed). Mandatory legal provisions – in particular statutory retention periods – remain unaffected.
Registration on this website
You can register on this website to use additional features on the site. We will use the data you enter only to use the respective offer or service for which you have registered. The mandatory information requested during registration must be provided in full. Otherwise, we will reject your registration.
For important changes, such as changes to the scope of services or technically necessary changes, we will use the email address you provided during registration to inform you.
The data entered during registration is processed for the purpose of implementing the user relationship established by the registration and, if necessary, for initiating further contracts (Art. 6 (1) (b) GDPR).
The data collected during registration will be stored by us for as long as you are registered on this website and will then be deleted. Statutory retention periods remain unaffected.
Cookies
Our websites use so-called "cookies." Cookies are small data packets and do not cause any damage to your device. They are stored either temporarily for the duration of a session (session cookies) or permanently (permanent cookies) on your device. Session cookies are automatically deleted after your visit. Permanent cookies remain stored on your device until you delete them yourself, or they are automatically deleted by your web browser.
Cookies can come from us (first-party cookies) or from third-party companies (so-called third-party cookies). Third-party cookies enable the integration of certain third-party services within websites (e.g., cookies for processing payment services).
Cookies have various functions. Many cookies are technically necessary, as certain website functions would not work without them (e.g., the shopping cart function or the display of videos). Other cookies can be used to evaluate user behavior or for advertising purposes.
Cookies that are required to carry out electronic communication, to provide certain functions you request (e.g., for the shopping cart function), or to optimize the website (e.g., cookies for measuring web audiences) (necessary cookies) are stored based on Art. 6 (1) (f) GDPR, unless another legal basis is specified. The website operator has a legitimate interest in storing necessary cookies for the technically error-free and optimized provision of its services. If consent to the storage of cookies and similar recognition technologies has been requested, processing will take place exclusively based on this consent (Art. 6 (1) (a) GDPR and Section 25 (1) TDDDG); consent can be revoked at any time.
You can set your browser to inform you about the use of cookies and to only allow cookies in individual cases, to exclude the acceptance of cookies for certain cases or generally, and to activate the automatic deletion of cookies when closing the browser. If cookies are deactivated, the functionality of this website may be limited.
You can find out whether and which cookies and services are used on this website in this privacy policy.
Use of Chatbots
We use chatbots to communicate with you. Chatbots are able to respond to your questions and other inputs without human assistance. To do so, the chatbots analyze your input as well as other data to provide appropriate answers (e.g., chat histories).
User profiles can be created based on the collected data.
The collected data can also be used to improve our chatbots and their response behavior (machine learning).
The data you enter during communication will remain with us or the chatbot operator until you request deletion, revoke your consent to storage, or the purpose for storing the data no longer applies (e.g., after your request has been processed). Mandatory statutory provisions – in particular retention periods – remain unaffected.
The legal basis for the use of chatbots is Art. 6 (1) (b) GDPR, provided the chatbot is used to initiate or fulfill a contract. If consent has been requested, processing will be carried out exclusively based on Art. 6 (1) (a) GDPR and Section 25 (1) TDDDG, insofar as the consent includes the storage of cookies or access to information on the user's device (e.g., device fingerprinting) within the meaning of the TDDDG. Consent can be revoked at any time. In all other cases, the use is based on our legitimate interest in the most effective customer communication possible (Art. 6 (1) (f) GDPR).
We use the following chatbots:
meRfi – Medical Research Finder GmbH
The provider is meRfi – Medical Research Finder GmbH, Amselweg 7, 51503 Rösrath (hereinafter "meRfi").

3. eCommerce and Payment Providers
Processing of Customer and Contract Data
We collect, process, and use personal customer and contract data to establish, define, and modify our contractual relationships.

Data transfer upon conclusion of a contract for services and digital content
We only transfer personal data to third parties if this is necessary for the execution of the contract, for example, to the credit institution responsible for payment processing.
Further transfer of data will not occur unless you have expressly consented to the transfer. Your data will not be passed on to third parties without your express consent, for example, for advertising purposes.
The basis for data processing is Art. 6 (1) (b) GDPR, which permits the processing of data for the fulfillment of a contract or pre-contractual measures.
Encrypted payment transactions on this website
If, after concluding a paid contract, you are required to provide us with your payment details (e.g., account number for direct debit authorization), this data is required for payment processing.
Payment transactions using common payment methods (Visa/MasterCard, direct debit) are carried out exclusively via an encrypted SSL or TLS connection. You can recognize an encrypted connection by the fact that the browser's address bar changes from "http://" to "https://" and by the lock symbol in your browser bar.
With encrypted communication, the payment details that you transmit to us cannot be read by third parties.
Payment Services
We integrate payment services from third-party companies on our website. When you purchase from us, your payment data (e.g., name, payment amount, account details, and credit card number) will be processed by the payment service provider for payment processing. The respective contractual and data protection provisions of the respective providers apply to these transactions. The use of payment service providers is based on Art. 6 (1) (b) GDPR (contract processing) and in the interest of ensuring the smoothest, most convenient, and most secure payment process possible (Art. 6 (1) (f) GDPR).
We use the following payment services/payment service providers on this website:
Stripe

4. Rights of Data Subjects
Information, Correction, and Deletion
Within the scope of applicable legal provisions, you have the right at any time to obtain free information about your stored personal data, its origin and recipient, and the purpose of data processing, as well as, if applicable, the right to have this data corrected or deleted. You can contact us at any time with any questions about this or other issues relating to personal data.
Right to Restriction of Processing
You have the right to request that the processing of your personal data be restricted. You can contact us at any time to do so. The right to restriction of processing applies in the following cases:
• If you dispute the accuracy of your personal data stored by us, we generally need time to verify this. You have the right to request that the processing of your personal data be restricted while we verify this.
• If the processing of your personal data was/is unlawful, you can request that its processing be restricted instead of erased.
• If we no longer need your personal data, but you need it to exercise, defend, or assert legal claims, you have the right to request that its processing be restricted instead of erased.
• If you have lodged an objection under Art. 21 (1) GDPR, your interests must be weighed against ours. As long as it is not yet clear whose interests prevail, you have the right to request that the processing of your personal data be restricted.
If you have restricted the processing of your personal data, this data may – except its storage – only be processed with your consent or for the establishment, exercise or defense of legal claims or to protect the rights of another natural or legal person or for reasons of important public interest of the European Union or a Member State.
Right to data portability
You have the right to have data that we process automatically based on your consent or in fulfillment of a contract handed over to you or a third party in a common, machine-readable format. If you request the direct transfer of the data to another controller, this will only be done if technically feasible.
Revocation of your consent to data processing
Many data processing operations are only possible with your express consent. You can revoke your consent at any time. The legality of the data processing carried out up to the time of revocation remains unaffected by the revocation.
Right to object to data collection in special cases and to direct marketing (Article 21 GDPR)
If data processing is based on Article 6 (1) (e) or (f) of the GDPR, you have the right to object at any time to the processing of your personal data for reasons related to your particular situation; this also applies to profiling based on these provisions. The respective legal basis on which processing is based can be found in this privacy policy. If you object, we will no longer process your personal data unless we can prove compelling legitimate grounds for the processing that override your interests, rights, and freedoms or the processing serves to assert, exercise, or defend legal claims (objection under article 21(1) GDPR). If your personal data is processed for direct marketing purposes, you have the right to object at any time to the processing of your personal data for such marketing purposes; this also applies to profiling insofar as it is associated with such direct marketing. If you object, your personal data will subsequently no longer be used for direct marketing purposes (objection under Article 21 (2) GDPR).
The right to complain to the competent supervisory authority
In the event of violations of the GDPR, data subjects have the right to lodge a complaint with a supervisory authority, in particular in the Member State of their habitual residence, place of work, or place of the alleged violation. This right of complaint is without prejudice to other administrative or judicial remedies.
