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. A complete protection of data against access by third parties is not possible.
The responsible body for data processing on this website is:
Stephanie Abrecht
SA Safe AI
c/o Postflex #9568
Emsdettener Str. 10
48268 Greven
Phone: +49 (0) 152 07245871
Email: trendsurfer@hiddencore.ai
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.).
Unless a more specific storage duration has been specified in this privacy policy, your personal data will remain with us until the purpose for the 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, unless we have other legally permissible reasons for storing your personal data (e.g. tax or commercial retention periods); in the latter case, the deletion will take place after these reasons have ceased to exist.
Specific Retention Periods:
If you have consented to data processing, we process your personal data on the basis of Art. 6 (1) lit. a GDPR or Art. 9 (2) lit. a GDPR, provided that special categories of data are processed according to Art. 9 (1) GDPR. In the case of express consent to the transfer of personal data to third countries, data processing is also carried out on the basis of Art. 49 (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), the data processing is additionally based on § 25 (1) TDDDG. The consent can be revoked at any time. If your data is required for the fulfillment of a contract or for the implementation of pre-contractual measures, we process your data on the basis of Art. 6 (1) lit. b GDPR. Furthermore, we process your data if this is necessary to fulfill a legal obligation on the basis of Art. 6 (1) lit. c GDPR. Data processing can also take place on the basis of our legitimate interest in accordance with Art. 6 (1) lit. f GDPR. Information on the relevant legal bases in individual cases is provided in the following paragraphs of this privacy policy.
As part of our business activities, we work together with various external bodies. In some cases, it is also necessary to transfer personal data to these external bodies. We only pass on personal data to external bodies if this is necessary within the framework of fulfilling a contract, 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 (1) lit. f GDPR in passing it on 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.
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.
If data processing is carried out on the basis of Art. 6 (1) lit. e or f GDPR, you have the right to object to the processing of your personal data at any time 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 for the establishment, exercise or defense of legal claims (objection under Art. 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 personal data concerning you for such marketing; this also applies to profiling to the extent that 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 under Art. 21 (2) GDPR).
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 exists without prejudice to other administrative or judicial remedies.
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 standard, machine-readable format. If you request the direct transfer of the data to another person responsible, this will only be done insofar as this is technically feasible.
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 the 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.
You have the right to request the restriction of the processing of your personal data. You can contact us at any time for this purpose. The right to restriction of processing exists in the following cases:
If you have restricted the processing of your personal data, this data – apart from its 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 important public interest of the European Union or a Member State.
This site uses SSL or TLS encryption for security reasons and to protect the transmission of confidential content, such as orders or requests 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.
Our websites use so-called "cookies". Cookies are small data packets and do not cause any damage to your end device. They are stored either temporarily for the duration of a session (session cookies) or permanently (permanent cookies) on your end device. Session cookies are automatically deleted after your visit. Permanent cookies remain stored on your end device until you delete them yourself or they are automatically deleted by your web browser.
Cookies can originate from us (first-party cookies) or from third-party companies (so-called third-party cookies). Third-party cookies enable the integration of certain services from third-party companies within websites (e.g. cookies for processing payment services).
Cookies have various functions. Numerous cookies are technically necessary because 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 necessary to carry out the electronic communication process, to provide certain functions you have requested (e.g. for the shopping cart function) or to optimize the website (e.g. cookies for measuring the web audience) (necessary cookies) are stored on the basis of Art. 6 (1) lit. f GDPR, unless another legal basis is specified. The website operator has a legitimate interest in the storage of necessary cookies for the technically error-free and optimized provision of its services. If consent to the storage of cookies and comparable recognition technologies has been requested, the processing takes place exclusively on the basis of this consent (Art. 6 (1) lit. a GDPR and § 25 (1) TDDDG); consent can be revoked at any time.
You can set your browser so that you are informed about the setting of cookies and only allow cookies in individual cases, exclude the acceptance of cookies for certain cases or in general, and activate the automatic deletion of cookies when answering the browser. If cookies are deactivated, the functionality of this website may be restricted.
Which cookies and services are used on this website can be found in this privacy policy.
The provider of the pages automatically collects and stores information in so-called server log files, which your browser automatically transmits to us. These are:

This data is collected on the basis of Art. 6 (1) lit. 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 recorded.
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 for the purpose of processing the inquiry and in the event of follow-up questions. We will not pass on this data without your consent.
The processing of this data takes place on the basis of Art. 6 (1) lit. b GDPR, provided that your request is related to the fulfillment of a contract or is necessary for the implementation of pre-contractual measures. In all other cases, the processing is based on our legitimate interest in the effective processing of the inquiries addressed to us (Art. 6 (1) lit. f GDPR) or on your consent (Art. 6 (1) lit. a GDPR) if this was requested; the consent can be revoked at any time.
The data you enter in the contact form will remain with us until you request us to delete it, revoke your consent to storage or the purpose for data storage no longer applies (e.g. after your request has been processed). Mandatory statutory provisions - in particular retention periods - remain unaffected.

Confirmation and notification emails are sent via the service Resend named above. The legal basis is Art. 6(1)(b) and (c) GDPR. There is no link to your customer account. The data is deleted as soon as it is no longer required for processing and for the statutory retention periods.
If you wish to subscribe to the newsletter offered on the website, we require an email address from you as well as information that allows us to verify that you are the owner of the email address provided and that you agree to receive the newsletter. No further data is collected, or only on a voluntary basis. We use this data exclusively for sending the requested information and do not pass it on to third parties.
The processing of the data entered in the newsletter registration form is based exclusively on your consent (Art. 6 (1) lit. a GDPR). You can revoke your consent to the storage of data, the email address, and its use for sending the newsletter at any time, for example via the "unsubscribe" link in the newsletter.

We have concluded a Data Processing Addendum with beehiiv based on the EU Standard Contractual Clauses to ensure the protection of your data when transferred to the USA. Details on data processing by beehiiv can be found in their privacy policy at: https://www.beehiiv.com/privacy
The data you have provided for the purpose of receiving the newsletter will be stored by us or the newsletter service provider until you unsubscribe from the newsletter and will be deleted from the newsletter distribution list after you cancel the newsletter or after the purpose ceases to apply. We reserve the right to delete or block email addresses from our newsletter distribution list at our own discretion within the scope of our legitimate interest pursuant to Art. 6 (1) lit. f GDPR.
Data stored by us for other purposes remains unaffected.
After you unsubscribe from the newsletter distribution list, your email address may be stored by us or the newsletter service provider in a blocklist to prevent future mailings if necessary.

This serves both your interest and our interest in complying with legal requirements when sending newsletters (legitimate interest within the meaning of Art. 6 (1) lit. f GDPR). Storage in the blocklist is not limited in time. You may object to the storage if your interests outweigh our legitimate interest.

In doing so, information about your visit (in particular pages visited, browser type, operating system, referrer URL, IP address, and device/browser identifiers) is transmitted to Meta and linked to your Meta account, if you have one and are logged in.
The Meta Pixel sets the cookies _fbp and _fbc, each with a maximum lifetime of 90 days.
Processing takes place exclusively on the basis of your consent pursuant to Art. 6 (1) lit. a GDPR and § 25 (1) TDDDG.

After your consent, Google Analytics sets in particular the cookies _ga and _ga_G3XQ2J339V, each with a lifetime of up to 2 years, to recognise returning visitors pseudonymously.
Google Analytics 4 does not record or store full IP addresses. The IP address is only used briefly to derive the approximate location and is not stored permanently.
Processing takes place exclusively on the basis of your consent pursuant to Art. 6 (1) lit. a GDPR and § 25 (1) TDDDG. The consent can be revoked at any time via the cookie settings in the footer of this website. The lawfulness of processing carried out until the revocation remains unaffected by the revocation.

In addition, we use the session recording feature (Session Replay): your mouse movements, scrolling behaviour, clicks and other interactions with our site are recorded and can be replayed as an anonymised session, so that we can identify usability problems and improve the site. All input fields (for example form and text entries) are automatically masked and are never recorded.
After your consent, PostHog sets a cookie and stores entries in your browser's local storage (localStorage) with the prefix ph_ (for example ph_<projectkey>_posthog) in order to recognise returning visits pseudonymously. The storage duration is typically around 12 months.
Processing takes place exclusively on the basis of your consent pursuant to Art. 6 (1) lit. a GDPR and § 25 (1) TDDDG.
