Data Collection on This Website


Who is responsible for data collection on this website?

Data processing on this website is carried out by the website operator. You can find their contact details in the section 'Notice on the Responsible Party' in this privacy policy.

How do we collect your data?

Your data is collected in part by you providing it to us. This could be data that you enter in a contact form, for example. Other data is collected automatically or with your consent by our IT systems when you visit the website. This is primarily technical data (e.g., internet browser, operating system, or time of page access). This data is collected automatically as soon as you enter this website.

What do we use your data for?

Part of the data is collected to ensure error-free provision of the website. Other data may be used to analyze your user behavior. If contracts can be concluded or initiated via the website, the transmitted data is also processed for contract offers, orders, or other order inquiries.

What rights do you have regarding your data?

You have the right at any time to receive information free of charge about the origin, recipients, and purpose of your stored personal data. You also have the right to request the correction or deletion of this data. If you have given consent to data processing, you can revoke this consent at any time for the future. You also have the right, under certain circumstances, to request the restriction of the processing of your personal data. Furthermore, you have the right to lodge a complaint with the competent supervisory authority. You can contact us at any time regarding this and other questions on the subject of data protection.

Analytics Tools and Third-Party Tools

When visiting this website, your browsing behavior may be statistically analyzed. This is done primarily with so-called analytics programs. Detailed information about these analytics programs can be found in the following privacy policy.

1. General information and mandatory disclosures


The protection of your personal data is of particular concern to us. We process your data exclusively on the basis of legal provisions (GDPR, BDSG, TDDDG). In this privacy policy, we inform you comprehensively about the nature, scope and purpose of the collection and use of personal data on the platform fin (analysewithfin.com).

We would like to point out that data transmission over the Internet (e.g., when communicating by email) may have security vulnerabilities. Complete protection of data against access by third parties is not possible.


General Notes on the Legal Bases of Data Processing on This Website

If you have consented to data processing, we process your personal data on the basis of Art. 6(1)(a) GDPR or Art. 9(2)(a) GDPR, if special categories of data pursuant to Art. 9(1) GDPR are processed. In the case of explicit consent to the transfer of personal data to third countries, data processing is also carried out on the basis of Art. 49(1)(a) GDPR. If you have consented to the storage of cookies or to access to information on your device (e.g., via device fingerprinting), data processing is additionally carried out on the basis of § 25(1) TDDDG. Consent can be revoked at any time. If your data is required for contract fulfillment or for the implementation of pre-contractual measures, we process your data on the basis of Art. 6(1)(b) GDPR. Furthermore, we process your data if this is necessary for the fulfillment of a legal obligation on the basis of Art. 6(1)(c) GDPR. Data processing may also be carried out on the basis of our legitimate interest pursuant to Art. 6(1)(f) GDPR. The relevant legal bases in each individual case are explained in the following paragraphs of this privacy policy.


Encrypted Payment Transactions on This Website

If, after concluding a paid contract, there is an obligation to transmit your payment data to us (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 browser's address bar changing from 'http://' to 'https://' and by the lock icon in your browser bar.

With encrypted communication, your payment data that you transmit to us cannot be read by third parties.


Information, Blocking, Deletion

Within the framework of the applicable legal provisions, you have the right at any time to obtain free information about your stored personal data, its origin and recipients, and the purpose of data processing, and, where applicable, a right to correction, blocking, or deletion of this data. For this purpose and for further questions on the subject of personal data, you can contact us at any time at the address given in the legal notice.


Objection to Advertising Emails

The use of contact data published as part of the legal notice obligation for sending unsolicited advertising and information materials is hereby objected to. The operators of the pages expressly reserve the right to take legal action in the event of the unsolicited sending of advertising information, such as spam emails.

7. Data sharing with third parties


In the course of our business activities, we work with various external parties. In some cases, the transfer of personal data to these external parties is also necessary. We only pass on personal data to external parties if this is necessary as part of contract fulfillment, if we are legally obligated to do so (e.g., disclosure of data to tax authorities), if we have a legitimate interest pursuant to Art. 6(1)(f) GDPR in the disclosure, or if another legal basis permits the data transfer. When using processors, we only pass on personal data of our customers on the basis of a valid data processing agreement. In the case of joint processing, a joint processing agreement is concluded.

Personal data is only shared with third parties in the following cases:

  • For contract fulfillment (e.g., payment processing via Stripe)

  • With your explicit consent

Under no circumstances will your data be sold or shared with third parties for advertising purposes.

9. Data retention


Unless a more specific storage period has been stated within this privacy policy, your personal data will remain with us until the purpose for data processing no longer applies. If you assert a legitimate request for deletion or revoke consent to data processing, your data will be deleted unless we have other legally permissible reasons for storing your personal data (e.g., tax or commercial law retention periods); in the latter case, deletion will take place after these reasons cease to apply.

Personal data is only stored for as long as it is necessary for the respective processing purpose or as required by statutory retention periods:

10. Your rights as a data subject


Revocation of Your Consent to Data Processing

Many data processing operations are only possible with your express consent. You can revoke consent that has already been given at any time. The legality of the data processing carried out until the revocation remains unaffected by the revocation.


Right to Object to Data Collection in Special Cases and to Direct Marketing (Art. 21 GDPR)

IF DATA PROCESSING IS BASED ON ART. 6(1)(E) OR (F) GDPR, YOU HAVE THE RIGHT AT ANY TIME TO OBJECT TO THE PROCESSING OF YOUR PERSONAL DATA FOR REASONS ARISING FROM 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 AFFECTED PERSONAL DATA UNLESS WE CAN DEMONSTRATE COMPELLING LEGITIMATE GROUNDS FOR THE PROCESSING WHICH OVERRIDE YOUR INTERESTS, RIGHTS AND FREEDOMS, OR THE PROCESSING SERVES THE ESTABLISHMENT, EXERCISE OR DEFENSE OF LEGAL CLAIMS (OBJECTION PURSUANT TO ART. 21(1) GDPR).

IF YOUR PERSONAL DATA IS PROCESSED FOR THE PURPOSE OF DIRECT MARKETING, YOU HAVE THE RIGHT TO OBJECT AT ANY TIME TO THE PROCESSING OF YOUR PERSONAL DATA FOR THE PURPOSE OF SUCH MARKETING; THIS ALSO APPLIES TO PROFILING INSOFAR AS IT IS RELATED TO SUCH DIRECT MARKETING. IF YOU OBJECT, YOUR PERSONAL DATA WILL SUBSEQUENTLY NO LONGER BE USED FOR THE PURPOSE OF DIRECT MARKETING (OBJECTION PURSUANT TO ART. 21(2) GDPR).


Under the GDPR, you have the following rights:

  • Right of access (Art. 15 GDPR) – You can request information about your personal data stored by us.
  • Right to rectification (Art. 16 GDPR) – You can request the correction of inaccurate data.
  • Right to erasure (Art. 17 GDPR) – You can request the deletion of your data, provided no statutory retention obligations exist.
  • Right to restriction of processing (Art. 18 GDPR)

    The right to restriction of processing exists in the following cases:

    • If you dispute the accuracy of your personal data stored by us, we generally need time to verify this. For the duration of the verification, you have the right to request the restriction of the processing of your personal data.
    • If the processing of your personal data was/is unlawful, you may request the restriction of data processing instead of deletion.
    • If we no longer need your personal data, but you need it for the exercise, defense or assertion of legal claims, you have the right to request the restriction of the processing of your personal data instead of deletion.
    • If you have lodged an objection pursuant to Art. 21(1) GDPR, a balancing of your and our interests must be carried out. As long as it has not yet been determined whose interests prevail, you have the right to request the restriction of the processing of your personal data.

    If you have restricted the processing of your personal data, this data may – apart from being stored – only be processed with your consent or for the assertion, exercise or defense of legal claims or for the protection of 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 (Art. 20 GDPR) – You can receive your data in a structured, commonly used and machine-readable format.

    If you request the direct transfer of data to another controller, this will only be done to the extent that it is technically feasible.

  • Right to object (Art. 21 GDPR) – You can object to the processing of your data based on legitimate interest.
  • Right to withdraw consent (Art. 7 para. 3 GDPR) – You can withdraw a given consent at any time with effect for the future.
