3. General Notes and Mandatory Information

Data Protection

The operators of these pages take the protection of your personal data very seriously. We treat your personal data confidentially and in accordance with the statutory data protection regulations and this privacy policy.

When you use this website, various personal data is collected. Personal data is data with which you can be personally identified. This privacy policy explains what data we collect and what we use it for. It also explains how and for what purpose this happens.

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

Note on the Responsible Body

The responsible body for data processing on this website is:

Dirk Thonig
Limburgerstr. 74B
04229 Leipzig, Germany

Phone: +49 1578 4948007

The responsible body is the natural or legal person who alone or jointly with others decides on the purposes and means of processing personal data (e.g., names, email addresses, etc.).

Storage Duration

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

General Information on the Legal Basis for Data Processing on this Website

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

Recipients of Personal Data

In the context of our business activities, we work together with various external bodies. In some cases, the transmission of personal data to these external bodies is also necessary. We only pass on personal data to external bodies if this is necessary within the framework of contract fulfillment, if we are legally obliged to do so (e.g., passing on data to tax authorities), if we have a legitimate interest in accordance with Art. 6 Para. 1 lit. f GDPR in the transfer, 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 contract for order processing. In the case of joint processing, a contract for joint processing is concluded.

Revocation of Your Consent to Data Processing

Many data processing operations are only possible with your express consent. You can revoke consent you have already 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 Advertising (Art. 21 GDPR)

IF DATA PROCESSING IS CARRIED OUT ON THE BASIS OF ART. 6 PARA. 1 LIT. 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 PROVE COMPELLING WORTHY OF PROTECTION REASONS FOR THE PROCESSING THAT OUTWEIGH YOUR INTERESTS, RIGHTS, AND FREEDOMS OR THE PROCESSING SERVES THE ASSERTION, EXERCISE, OR DEFENSE OF LEGAL CLAIMS (OBJECTION ACCORDING TO ART. 21 PARA. 1 GDPR).

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

Right of Appeal to the Competent Supervisory Authority

In the event of violations of the GDPR, the persons concerned have a right of appeal to a supervisory authority, in particular in the member state of their habitual residence, their place of work, or the place of the alleged violation. The right of appeal applies without prejudice to other administrative or judicial remedies.

Right to Data Portability

You have the right to have data that we process automatically on the basis of your consent or in fulfillment of a contract handed over to you or to a third party in a common, machine-readable format. If you request the direct transfer of the data to another person responsible, this will only take place if it is technically feasible.

Information, Correction, and Deletion

Within the framework of the applicable legal provisions, you have the right at any time to free information about your stored personal data, its origin and recipient and the purpose of data processing and, if applicable, a right to correction or deletion of this data. You can contact us at any time regarding this and other questions on the subject of personal data.

Right to Restriction of Processing

You have the right to request the restriction of the processing of your personal data. You can contact us at any time regarding this. The right to restrict processing exists in the following cases:

  • If you dispute the accuracy of your personal data stored by us, we usually need time to check this. For the duration of the examination, you have the right to request the restriction of the processing of your personal data.
  • If the processing of your personal data happened/is happening unlawfully, you can 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 in accordance with Art. 21 Para. 1 GDPR, a balance must be made between your interests and ours. As long as it is not yet clear 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, these data – apart from their storage – may 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 an important public interest of the European Union or a Member State.

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 fact that the address line of the browser changes from "http://" to "https://" and by the lock symbol in your browser line.

If SSL or TLS encryption is activated, the data you transmit to us cannot be read by third parties.

Objection against Advertising Emails

The use of contact data published within the scope of the imprint obligation for the transmission of not expressly requested advertising and information materials is hereby contradicted. 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.

4. Analysis Tools

Vercel Web Analytics

We use the analysis tool "Vercel Web Analytics" from the provider Vercel Inc., 440 N Barranca Ave #4133, Covina, CA 91723, USA, on this website.

Legal Basis and Consent

The analysis is performed exclusively on the basis of your express consent in accordance with Art. 6 (1) (a) GDPR and § 25 (1) TDDDG (storage of information in, and access to information in, your terminal equipment).

The Vercel Web Analytics measurement script is loaded only after you have actively consented via our consent banner. If you do not grant or if you withdraw your consent, no analysis takes place. How you grant, inspect, or withdraw your consent is described in § 6 Consent Management.

Your consent can be withdrawn at any time; the lawfulness of any processing carried out up to the point of withdrawal remains unaffected.

Data Collected

Vercel Web Analytics operates without cookies. Visitors are identified by a hash derived from the incoming request; this hash is automatically reset every 24 hours and does not allow recognition across different days or different websites.

For every recorded page view, the following data points are transmitted: event timestamp, accessed URL, dynamic path, referrer, filtered query parameters, rough geolocation (country, region, city), operating system and browser version, device type, and the version of the analytics script. No personal identifiers are collected that would track or identify you beyond our website.

Data Transfer to the USA

Vercel Inc. is based in the USA. For the transfer of personal data to the USA, the Standard Contractual Clauses of the EU Commission described in § 2 Hosting apply; these are part of the Data Processing Addendum concluded between us and Vercel.

Further information on data protection at Vercel can be found at: https://vercel.com/legal/privacy-policy

Search (Pagefind)

The search function of this website is provided by Pagefind. The search index is part of the static website bundle and is served from the same origin as the website itself. Pagefind has no server component; the search runs entirely in your browser.

Your search queries do not leave your device, are not transmitted to us or to third parties, and are not logged. No cookies are set as part of the search function and no personal data is collected. No consent is required for the use of the search.

5. Google Forms

Bonus Application Form

We use Google Forms (provider: Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland; parent company: Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA) for the application form of our eToro bonus program.

Data Collected

When using the form, the following data is collected:

  • Email address
  • Your responses to the application questions (free-text fields about your understanding of our strategy)

Purpose of Processing

The data is used exclusively to evaluate your application for one of the limited bonus slots and to send you the referral link via email.

Legal Basis

Processing is based on your consent in accordance with Art. 6(1)(a) GDPR. By actively submitting the form, you consent to the processing of the data you entered. You may withdraw this consent at any time with effect for the future by contacting us via email.

Processor and Data Transfer to the USA

Google processes the form data as a processor. Google LLC is based in the USA and is certified under the EU-U.S. Data Privacy Framework (DPF), which ensures an adequate level of data protection.

Further information on data protection at Google can be found at: https://policies.google.com/privacy

Retention

Your application data is stored for a maximum of 6 months after the conclusion of the respective bonus program round and then deleted. In the case of a successful application, only the email address is retained for the duration of the bonus campaign.

6. Consent Management

Purpose and legal basis

The purpose of consent management is to capture, store, and enforce your decision regarding the use of services that require consent (e.g., Vercel Web Analytics, see § 4) on every page view. The legal basis for the storage of the consent record itself is § 25 (2) No. 2 TDDDG (strictly necessary): without this record, we could neither document nor enforce your choice. A separate consent for the storage of the record is therefore not required.

How consent is captured

On your first visit to this website, a consent banner appears. You must make an explicit choice – either "Accept" or "Reject". Silently dismissing the banner is not possible. As long as you have not made a choice, no services that require consent are loaded.

Where and how your choice is stored

Your choice is stored exclusively in your browser – not on our servers. The storage takes place in localStorage under the key ck-consent as a JSON record with three fields:

  • status – the value "accepted" or "rejected", depending on your choice.
  • version – an integer identifying the version of this policy in force at the time of your choice (see "Policy versioning" below).
  • timestamp – the point in time of your choice in ISO-8601 format.

You may inspect this record at any time via your browser's developer tools.

Retention

The record persists in your browser until (a) you clear the site data in your browser, (b) you change your choice via the footer "Privacy settings" link, or (c) this policy materially changes and the version stored in the record no longer matches the current CONSENT_VERSION (see "Policy versioning" below). There is no time-based automatic expiry.

Changing or withdrawing your consent

In the footer of every page you will find the "Privacy settings" link. Clicking it reopens the consent banner with your current choice pre-loaded. You may change your decision (e.g., from "Accept" to "Reject" or vice versa) or withdraw a consent you have previously granted. The change takes effect on the next page load: after rejection, no further analytics script is loaded; after renewed consent, it is loaded again. The lawfulness of any processing carried out up to the point of withdrawal remains unaffected.

Policy versioning

When this policy materially changes (e.g., a new processor, a changed purpose, or a changed legal basis), the internal CONSENT_VERSION constant is incremented. On your next visit, the consent banner then reappears and asks for a fresh decision. Your previous choice is treated as superseded.

No third-party transmission

The ck-consent record does not leave your device. It is not transmitted to us, to Vercel, or to any other third party. The management of your consent takes place exclusively locally in your browser.
