This is done on the basis of Art. 6(1)(f) GDPR (legitimate interest in efficient and privacy-compliant video delivery). For more information, please see Bunny.net's privacy policy: https://bunny.net/privacy.

Data Processing Agreement

We have entered into a data processing agreement (DPA) with the above-mentioned providers. This is a legally required contract that ensures that these providers process the personal data of our website visitors only according to our instructions and in compliance with the GDPR.

3. General Information 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 legal data protection regulations and this privacy notice.

If you use this website, various personal data will be collected. Personal data is data that can be used to personally identify you. This privacy notice explains what data we collect and what we use it for. It also explains how and for what purpose this is done.

We would like to point out that data transmission over 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.

Notice of the Responsible Entity

The responsible entity for data processing on this website is:

Tobias Grawinkel (nuuminds)
Driesener Straße 8 B
D-10439 Berlin

hello@nuuminds.com

The responsible party 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 Period

Unless a more specific storage period has been mentioned 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 legitimate 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 cease to exist.

Revocation of your consent to data processing

Many data processing operations are only possible with your express consent. You can revoke a consent already given at any time. The lawfulness of data processing that has taken place up to the revocation remains unaffected by the revocation.

Right to object to data collection in special cases as well as 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. You can find the respective legal basis on which processing is based in this privacy notice. If you object, we will no longer process your affected personal data unless we can demonstrate 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 Art. 21 para. 1 GDPR).

If your personal data is processed for the purpose of direct advertising, you have the right to object at any time to the processing of your personal data for the purpose of such advertising; this also applies to profiling, insofar as it is associated with such direct advertising. If you object, your personal data will subsequently no longer be used for the purpose of direct advertising (objection under Art. 21 para. 2 GDPR).

Right to lodge a complaint with 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. The right to lodge a complaint is 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 standard, machine-readable format. If you request the direct transfer of the data to another controller, this will only be done if it is technically feasible.

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

Information, deletion, and correction

Under the applicable legal provisions, you have the right to obtain free-of-charge information about your stored personal data, its origin and recipients, and the purpose of data processing, and if applicable, the right to correct or delete such data. For this purpose, as well as for any questions regarding personal data, you can contact us at any time.

Right to restrict processing

You have the right to request the restriction of processing of your personal data. For this purpose, you can contact us at any time. The right to restrict processing applies in the following cases:

  • If you dispute the accuracy of your personal data stored by us, we usually need time to verify this. During the period of verification, you have the right to request the restriction of 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 require it for exercising, defending, or claiming legal rights, you have the right to request the restriction of processing of your personal data instead of deletion.

  • If you have objected pursuant to Art. 21(1) GDPR, an assessment must be made as to whether your interests override ours. Until it has been determined whose interests prevail, you have the right to request the restriction of processing of your personal data.

If you have restricted the processing of your personal data, such data - apart from being stored - may only be processed with your consent or for the purpose of asserting, exercising, or defending legal claims or protecting the rights of another natural or legal person, or for reasons of important public interest of the European Union or a member state.

Objection to promotional emails

We hereby object to the use of contact data published within the scope of the imprint obligation for the purpose of sending unsolicited advertising and informational material. The operators of the pages expressly reserve the right to take legal action in the event of unsolicited advertising information, such as spam emails.

4. Data collection on this website

Cookies

Our website uses so-called "cookies". Cookies are small text files that do not cause any damage to your device. They are either stored temporarily for the duration of a session (session cookies) or permanently (persistent cookies) on your device. Session cookies are automatically deleted after your visit ends. Permanent cookies remain stored on your device until you delete them yourself or your web browser automatically deletes them.

In some cases, cookies from third-party companies can also be stored on your device when you enter our site (third-party cookies). These allow us or you to use certain services provided by the third-party company (e.g., cookies for payment processing).

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 are used to evaluate user behavior or display advertising.

Cookies that are necessary for electronic communication processes (necessary cookies) or to provide certain functions requested by you (functional cookies, such as the shopping cart function) or to optimize the website (e.g., cookies to measure website traffic) are stored on the basis of Art. 6 para. 1 lit. f GDPR, unless another legal basis is specified. The website operator has a legitimate interest in storing cookies for the technically error-free and optimized provision of its services. If consent to the storage of cookies has been requested, the storage of the respective cookies is based exclusively on this consent (Art. 6 para. 1 lit. a GDPR); the consent can be revoked at any time.

You can set your browser to inform you about the setting of cookies and allow cookies only in individual cases, exclude the acceptance of cookies for certain cases or in general, and activate the automatic deletion of cookies when the browser is closed. If cookies are deactivated, the functionality of this website may be limited.

To the extent that cookies are used by third-party companies or for analysis purposes, we will inform you separately within the scope of this data protection declaration and, if necessary, ask for your consent.

Contact form

If you send us inquiries via the contact form, your information 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 share this information without your consent.

The processing of this data is based on Art. 6 para. 1 lit. b GDPR, if your request is related to the performance of a contract or is necessary for the implementation of pre-contractual measures. In all other cases, processing is based on our legitimate interest in the effective processing of the inquiries addressed to us (Art. 6 para. 1 lit. f GDPR) or on your consent (Art. 6 para. 1 lit. a GDPR) if this has been requested.

The data you enter in the contact form will remain with us until you ask us to delete it, revoke your consent to storage, or the purpose for data storage no longer applies (e.g., after your inquiry has been processed). Mandatory legal provisions - especially retention periods - remain unaffected.

Inquiry by email, telephone or fax

If you contact us by email, telephone or fax, your request including all resulting personal data (name, request) will be stored and processed by us for the purpose of processing your request. We will not share this information without your consent.

The processing of this data is based on Art. 6 para. 1 lit. b GDPR, if your request is related to the performance of a contract or is necessary for the implementation of pre-contractual measures. In all other cases, processing is based on our legitimate interest in the effective processing of the inquiries addressed to us (Art. 6 para. 1 lit. f GDPR) or on your consent (Art. 6 para. 1 lit. a GDPR) if this has been requested.

The data you send us through contact requests will remain with us until you request deletion, revoke your consent for storage, or the purpose for data storage no longer applies (e.g. after completion of your request). Mandatory statutory provisions, especially statutory retention periods, remain unaffected.

Privacy Notice for our Social Media Profiles

Data processing by social networks

We maintain publicly accessible profiles on social networks. The social networks we use are listed below.

Social networks such as LinkedIn, Instagram, etc. can generally analyze your user behavior extensively if you visit their website or a website with integrated social media content (such as like buttons or advertising banners). By visiting our social media presence, numerous privacy-relevant processing operations are triggered. Specifically:

If you are logged in to your social media account and visit our social media presence, the operator of the social media portal can associate this visit with your user account. Under certain circumstances, your personal data may also be collected even if you are not logged in or do not have an account with the respective social media portal. This data collection may occur, for example, via cookies stored on your device or by capturing your IP address.

With the help of the data collected in this way, the operators of the social media portals can create user profiles in which your preferences and interests are stored. In this way, interest-based advertising can be displayed to you both inside and outside the respective social media presence. If you have an account with the respective social network, interest-based advertising can be displayed on all devices on which you are logged in or were logged in.

Please note that we cannot comprehensively trace all processing processes on the social media portals. Depending on the provider, additional processing operations may therefore be carried out by the operators of the social media portals. For details, please refer to the terms of use and privacy policy of the respective social media portals.

Legal basis

Our social media presence is intended to ensure the broadest possible presence on the Internet. This is a legitimate interest within the meaning of Art. 6 (1) lit. f GDPR. The analysis processes initiated by the social networks may be based on different legal bases, which are to be stated by the operators of the social networks (e.g. consent in accordance with Art. 6 (1) lit. a GDPR).

Responsible person and assertion of rights

When you visit one of our social media presences (e.g. Instagram), we are jointly responsible with the operator of the social media platform for the data processing operations triggered by this visit. You can exercise your rights (information, correction, deletion, restriction of processing, data portability, and complaint) in principle both with us and with the operator of the respective social media portal (e.g. Instagram).

Please note that despite our joint responsibility with the social media portal operators, we do not have full influence over the data processing operations of the social media portals. Our options are largely determined by the company policy of the respective provider.

Storage period

The data directly collected by us via the social media presence will be deleted from our systems as soon as the purpose for their storage no longer applies, you request us to delete them, you revoke your consent to their storage or the purpose for the data storage no longer applies. Stored cookies remain on your end device until you delete them. Mandatory legal provisions, in particular retention periods, remain unaffected.

We have no influence on the storage period of your data, which is stored by the operators of the social networks for their own purposes. For details, please contact the operators of the social networks directly (e.g. in their privacy policy, see below).
