Privacy Statement Stichting Amsterdam Dance Event

In this Privacy Statement, we aim to inform you as comprehensible and complete as possible about the way in which we may collect and use your (personal) data.

We are Stichting Amsterdam Dance Event, a foundation with full legal capacity, having its registered office in (1031 HV) Amsterdam at Wilgenweg 6 and registered with the chamber of commerce under KvK number 34292016 (in the following referred to as: ‘the ADE Foundation’). You can reach us at the aforementioned address or by email at [email protected] or in case of specific privacy issues at [email protected].

We organize the annual Amsterdam Dance Event, an international platform combining a business conference, a platform for brand activation and a(n) (indoor) festival consisting of events featuring electronic music (‘the ADE’), in part through our website(s), including but not limited to www.amsterdam-dance-event.nl, and/or the website(s) (of organization(s)) affiliated to our website(s) (the ‘Website(s)), web interfaces on our own and/or affiliated website(s) and our own social media pages and/or those of companies we work together with for the purpose of organizing the ADE (our ‘Partner Companies’), where our visitors to the business conference (‘Delegates’) and visitors to the festival (‘Visitors’) can directly make agreements or bookings, and the ADE Foundation apps linked to the Website(s) (together referred to as: the ‘Platform’). The Platform also includes any digital or AI-enabled assistant made available through the Website(s) or apps to help users find information about the ADE programme and events, including the Intelligent ADE Assistant (the “ADE Assistant”).

For the purpose of organizing the ADE, we may use (some of) the personal data of Visitors and/or and Delegates.

It is very important to us that data obtained from our visitors is used in a responsible manner. As such, we process and protect your personal data carefully and in compliance with the relevant provisions of the European General Data Protection Regulation (GDPR).

It is not compulsory to provide personal data to make use of the Platform. However, for some of our services it might be necessary to provide certain personal data.

1. The data we use

We may collect and/or use the following data of visitors to the ADE, the Website(s) and/or other parts of the Platform:

‘Registration Data’
Data you have provided to us yourself when:
- registering with us for an account, such as your name, gender, email and home address, place and date of birth, log-in name, password, profile picture and IP-address and/or data about your social network profiles, including website(s) such as LinkedIn, Twitter, Facebook, Spotify, SoundCloud and Instagram;
- purchasing products, such as your name, gender, email and home address, place and date of birth, log-in name, password, profile picture, IP-address and payment details;
- registering for specific services (for instance to perform at the ADE), such as your name, gender, email and home address, place and date of birth, log-in name, password, profile picture and IP-address; and/or
- registering for newsletters, such as name, gender, email and home address, place and date of birth, log-in name, password and IP-address.


Delegates may be asked to provide further information such as occupation, phone number, company data including company name, phone number, picture and address. We primarily use your Registration Data to carry out our agreement with you as best as we can or for the purposes of our internal administration.

‘External Data’
Data which we have access to through:
- our Partners (companies we have agreements with to provide you certain services, like Booking.com or KLM), which you have provided them in order to make use of their services;
- our Promoters (companies that organize an event that is part of the ADE festival and are responsible for the said event), but only in case you have provided them with such data in order to make use of their services;
- companies and other organisations such as your employer or another company or organisation that purchases or reserves a ticket on your behalf. We use this information to invite and register you for the relevant event, allocate and issue your ticket, provide you with necessary information regarding the event and administer access to the event. We process this information on the basis of our legitimate interest, and that of the organisation purchasing or reserving the ticket, in arranging your attendance at and access to the event. Unless continued retention is required by law or is necessary for the establishment, exercise or defence of legal claims, personal data received specifically for these purposes will be deleted no later than four weeks after the relevant event;
- and/or Third Parties (companies that provide certain online services through the Platform, such as Spotify, YouTube, Xaton, Paylogic or Facebook), upon providing them with your data and after registering with us through their (website(s) or app(s)) or when you make a payment for a purchase on the Platform.


‘Venue Data’
Data we have collected about which venues and corresponding performances you visited during the ADE. We collect these Venue Data when you check into a venue taking part in the ADE using a wristband containing an electronic chip.

‘Commercial Data’
Data we have collected and compiled about your online interests and buying behavior, which we will only use as anonymized data, except if you have given us permission to use it without anonymizing.

‘Surf Data’
Data we collect about your surfing behavior:
- on our Platform, such as your type of account and IP-address, the time of your visit and/or services you have used on or through the Platform
- technical information, such as your browser type and which functionalities you use which we only use anonymously or after having received your explicit permission. Part of Surf Data are cookies, which are discussed in a little more detail below.


‘ADE Assistant Data’
When you use the ADE Assistant, we process:
- the questions, words and options you enter or select;
- a randomly generated conversation identifier that enables the ADE Assistant to maintain the context of your conversation;
- your IP address for security, rate-limiting and misuse prevention;
- if you are logged in, a pseudonymous internal account identifier used to verify that the conversation relates to a valid session;
- if you are logged in, we provide the ADE Assistant with the events in your favourites list (without your name, email address or internal account identifier); and
- technical information about how the ADE Assistant works and whether errors occur, such as identifiers, counts, error types and status codes. The external system we use to monitor errors does not receive the questions you enter, the answers generated by the Assistant or other conversation content.


The ADE Assistant is not provided with your name, email address or other direct account details except for events in your favourites list. If you are logged in, relevant events from your favourites list may be provided to the ADE Assistant as described above. The internal account identifier is not transmitted to the AI model provider.

Because you can enter free text, the information you provide may contain personal data relating to you or another person. Please do not enter sensitive personal data or personal data that is not necessary for your question.

Besides the abovementioned data, we may use anonymized and combined data for various purposes, such as testing of our IT systems, research, data analyses, development of marketing and promotional models and new and improved appliances and services.

2. How we use your data

Registration and use of account

To create an account on the Platform, and to offer, deliver and invoice the products and/or services you order on our Platform through this account, we will use your Registration Data and/or External Data if you register through one of our Third Parties.

Upon registration with us, or if you have pre-registered, we will send you a welcoming email.

Furthermore, we will use your Registration Data and your Surf Data (such as user cookies) to verify that you are the same user who purchased certain products and/or services on the Platform, for example tickets, wrist bands and merchandise.

Only when you are registered as a Delegate, some of your Registration Data may become visible to other Delegates, in their accounts or in a physical guide. This is only possible for Delegates and is part of our agreement with Delegates to offer the full experience of a delegate ticket: to know which other Delegates will be attending in order to optimize their participation in the Conference by, for instance, networking and making new business contacts. Any other information besides your name, such as your e-mail address or telephone number, will only be made visible if you have given us permission to do so and as long as you have not withdrawn your permission.

We collect External Data when you register through one of our Third Parties or any third party has registered you on your behalf. We may use such External Data to adapt and be able to provide services adjusted to your tastes and interests.

On the Platform you also have the possibility to register for services from our Partners. In case you do so, we will not collect or use such External Data. It will be provided directly to those Partners and their privacy policy applies to further use they make thereof. We will make sure it is always clear to you when you are providing your data to such Partners. We will, however, collect Surf Data and Commercial Data about the interaction you have with our Partners in order to adjust and optimize our services to your interests in the future.

We may collect your Registration Data, Venue Data, Commercial Data and/or Surf Data to analyze the way in which you visit and use the Platform and purchase our products and services, or to make an anonymous profile of your interests and behavior, including the way in which you interact on various parts of the Platform such as purchase of products through us or our Partners or Third Parties.

From time to time, we may use the Registration Data to contact you for the purpose of market research.

The legal ground for the use of your data in the above is the necessity to perform our agreements with you and legitimate interests to know who makes use of our services and how. Where we use your data based on your explicit permission, you are always entitled to withdraw such permission in the way as set out below.

In order to offer you a personalized experience of the use of our Platform, we may lease data in an electronic form, for instance by placing third party pixels on our Website(s), to our carefully selected Third Parties, so that they are able to offer products or services. But only if you have given us permission to do so.


Use of the ADE Assistant
We use the ADE Assistant Data described in section 1 to answer your questions, search the ADE programme, provide relevant programme information, maintain the context of your conversation, protect the ADE Assistant and resolve technical problems.

The text you enter, together with the conversation context and relevant ADE programme information, is transmitted to our AI service provider, OpenAI, to generate a response, and may be used as or converted into a search query for our programme index. We also process limited technical information, including your IP address, session information and error logs, to secure the service, prevent misuse and investigate technical problems.

We use this information on the basis of our legitimate interests. This means that we use the information because it is reasonably necessary to provide, operate and secure the ADE Assistant, while limiting the impact on your privacy. More specifically:
- We use the question or options you enter to answer your question and find relevant events in the ADE programme. Without this information, the ADE Assistant cannot understand or answer your question.
- We use a randomly generated conversation identifier so that the ADE Assistant can remember the context when you ask a follow-up question. We use this random identifier instead of your name or email address.
- If you are logged in, we may use the events in your favourites list to show programme information and suggestions that are more relevant to the interests you have already indicated. The relevant favourite events are provided to the ADE Assistant without your name, email address or internal account identifier.
- We use your IP address to prevent misuse and excessive use of the ADE Assistant, for example by limiting the number of new conversations that can be started from the same IP address.
- If you are logged in, we use an internal account identifier to check that the conversation belongs to a valid session. The ADE Assistant does not use this identifier to identify you and the identifier is not sent to OpenAI.
- We keep technical logs for a limited period to find and resolve errors, investigate security incidents and keep the ADE Assistant working properly. These regular logs show the technical structure of a conversation turn, such as identifiers, block types, counts and text lengths, but do not contain the text you enter or the answers generated by the ADE Assistant. Access to these logs is limited to authorised personnel who need the information for these purposes. In exceptional cases, more detailed logging may be temporarily enabled where this is necessary to investigate a specific technical problem. If this includes conversation text, access is strictly limited and the information is deleted after the debugging session and no later than the maximum period described in section 5;
- We also use an external error-monitoring service. This service receives only limited technical details about an error, such as identifiers, counts, the type of error and a status code. It does not receive the question you entered, the answer generated by the ADE Assistant or the original error message received from OpenAI or our programme search provider.


We have considered your privacy interests when using this information. We therefore do not provide the ADE Assistant with your name or email address, do not use the content of your conversations for advertising or personalised marketing, and do not allow OpenAI to use the conversation data submitted through the relevant API to train its general models.

You have the right to object to processing based on our legitimate interests. More information about this right and how to exercise it is provided in section 7 below.

Subscriptions and forms
You will only receive our newsletters if you have subscribed to our newsletter, in which you will always have the possibility to unsubscribe.

If we have your explicit permission, we may use your Registration Data, Venue Data, Commercial Data and/or Surf Data to send you information about artists or speakers performing at ADE and events that might interest you.

To make (targeted) offers via advertising, email and/or social media networks and to keep you up-to-date on the latest news and/or updates and/or service announcements, we may use your Registration Data, Surf Data and/or Commercial Data;

The legal ground for this use of your data is your explicit permission and/or our legitimate interests to know how you make use of our services and improve our business.

Venue Data
In principle, these data shall only be processed as anonymized data for internal purposes such as statistics and to gain insight into visitor numbers. We will only use Venue Data in a non-anonymized form if you have explicitly given your prior permission.

Use of Venue Data helps us to improve our services, because it shows us which events and performances as part of the ADE have been popular and which have not. It also helps us to try to adapt our services to suit your wishes and expectations even more.

Anonymized Venue Data enable us to check whether our Promoters actually meet their obligation to us and allow the agreed minimum number of Delegates to enter the event in question.

You are able to link your Venue Data to your profile on selected social media networks. If you choose to do so, your Venue Data will be available on the selected social media network in a way that depends on the settings in your social media account settings. As long as you don’t explicitly choose for this option, the Venue Data will not be disclosed.

The social media networks in question are responsible for the use of data through this functionality, including the use of cookies they could use for this purpose. From the moment you choose this functionality, what the social media network does with your data is out of our hands. The privacy statements and conditions of those social media networks apply.

The legal ground for this use of your data is your explicit permission and/or our legitimate interests to improve our services.

Safety, security, access and incident handling
We may process personal data for access control, fraud prevention, incident handling and safeguarding the safety, security, public order and orderly conduct of ADE, any event, venue, staff, artists, visitors, delegates, promoters and other participants.

For these purposes, we may use registration details, ticket, pass or wristband details, access logs, venue data, incident reports and other relevant information available to us. This may include information necessary to verify admission rights, prevent or respond to incidents, enforce admission policies or house rules, suspend, cancel, revoke or invalidate tickets, passes, wristbands or other admission rights, refuse or restrict admission, or establish, exercise or defend legal claims. To the extent permitted by applicable law, we may receive and share relevant personal data with Promoters, Venues, ticketing partners, security personnel, competent public authorities, emergency services and other parties involved in the organisation, safety or security of ADE or any event. Where such information relates to suspected or actual criminal offences, criminal convictions or related security measures, we will only process such information where and to the extent permitted under applicable data protection laws

3. Third parties

We only share your Data with Partners, Promoters and Third Companies where we explicitly let you know.

We only disclose personal data to third parties where this is necessary for the purposes described in this Privacy Statement – for instance, to deliver products, services or tickets where we share data with our carefully selected processors – or where we have a valid legal basis, where you have given permission where required, or if we are required to do so by law.

To be able to provide our services, we use companies to process and store information including your Data (‘third party processors’). In order for them to carry out their agreement, we may transfer your Data to them. In such cases we will always make sure they are obliged to apply our same standards of processing and protection of your Data.

For the operation of the ADE Assistant, we use our service provider Bravoure for the development, hosting, middleware, technical management, logging and support of the service. We use OpenAI to process the text entered in the ADE Assistant and generate responses. We also use cloud, search, monitoring and security providers to host, operate and protect the service. All these third party processors may process personal data only for the agreed purposes and subject to applicable contractual and security requirements.

When you register for services from our Partners, your information will be handed over to those parties and their privacy policy applies to further use they make thereof. We will make sure it is always clear to you when you are providing your data to such Partners.

We may also share relevant personal data with Promoters, Venues, ticketing partners, security personnel, competent public authorities, emergency services and other parties involved in the organisation, safety or security of ADE or any event, where necessary for access control, fraud prevention, incident handling, safety, security, enforcement of admission policies or house rules, or the establishment, exercise or defence of legal claims, in each case to the extent permitted by applicable law.

4. Cookies and Surf Data

We may collect automatically generated Surf Data, including your IP-address and cookies. Our servers also automatically record certain data, such as the URL, IP address, browser type, language and the date and time of the visit to the Website(s). We store these Surf Data and use them make statistical analyses of visits to and use of the Website(s) and also to optimize the Website(s). We always anonymize Surf Data as much as possible.

To ensure that the Website(s) are working properly, we can, just as most websites do, use cookies to obtain information to make it easier for you to navigate the Website(s). These cookies are small text files that are saved on your computer and that contain the data necessary to ensure that your use of the Website(s) is as positive and effective as possible. This could include remembering your personal settings, such as language settings and preferences for mobile or desktop, the contents of a shopping basket and/or remembering that you are logged in. These cookies can be set via the settings used for the web browser.

We also use Google Analytics and Google Analytics cookies to gain an insight into how the Website(s) is (or are) used. This information (including IP-address) shall only be provided to Google when wanting to use the Google statistics program. We do not use other Google services when using Google Analytics. We have a Data Processing Agreement with Google and will make sure to partially anonymize the IP-address and switch off the option to share data.

When you use the ADE Assistant, our analytics systems may register that a question was submitted, that an event card was selected or which of the offered options you tapped. The text of your question or the content of the conversation is not included in these analytics events. Where your consent is legally required for these analytics technologies, we process the information only after you have given your consent. You can withdraw that consent through the cookie settings. Where consent is not legally required, we process these limited analytics events on the basis of our legitimate interest in understanding whether the ADE Assistant works properly and which basic functions are used.

Finally, cookies can be placed via the Website(s) and then read by Facebook, Twitter and KLM. We do not have any influence on the use of these data by these parties and they are responsible for this type of cookie use and their privacy statements and conditions shall apply in this situation.

5. Time limit

We do not retain personal data for longer than necessary for the purposes described in this Privacy Statement. The applicable retention period depends on why we use the information, the legal basis for the processing and whether we are legally required to retain it for a longer period.

In case we hold and use your personal data based on your permission, we will immediately remove your data upon withdrawal of your permission.

For the ADE Assistant, the following specific retention periods apply:
- conversation data processed by OpenAI is currently retained for up to 30 days and is not used to train OpenAI’s general models;
- the randomly generated conversation identifier remains in your browser or app until you reset or delete the conversation;
- technical session information is retained only for the duration necessary to maintain and validate the session;
- technical logs maintained in AWS CloudWatch, which in regular operation do not contain the text you enter or the answers generated by the ADE Assistant, are retained for no longer than 30 days;
- limited technical error information processed through our external error-monitoring service does not contain prompts, generated answers or other conversation content and is retained for no longer than 90 days;
- where logging of conversation text is temporarily enabled to investigate a specific technical problem, that text is deleted after completion of the debugging session;
- analytics events that do not contain conversation text are retained in accordance with the applicable analytics settings described in this Privacy Statement.


We may retain information for a longer period where this is necessary to investigate a security incident, comply with a legal obligation or establish, exercise or defend legal claims.

6. Withdrawal of permission

In case we use your personal data based on your explicit prior permission, you can at all times withdraw your permission by sending an email to [email protected] with a request and description of which permission you wish to withdraw. In case you make such a request we will provide you with a form to specify your request. Also, when we send you direct marketing messages for which we do not need your prior explicit permission, you are absolutely free to sign out from such messages. After you withdraw your consent, we will stop the relevant processing and delete the information where we have no other legal basis or legal obligation to retain it.

7. Access, removal, corrections and complaints

You are required to ensure that the Registration Data you provide to us is always correct. However, you of course always have the general privacy rights of access to and correction of your personal data, the right to be forgotten and to restriction of processing, the right of data portability, and the right not to be subjected to automated decision making (profiling), which means the following.

You are always free to contact us in writing via the e-mail address [email protected] to request information about whether or not we use any of your personal data, where and for what purpose we do so. Because the ADE Assistant is designed not to identify you directly, we may need information such as the relevant conversation identifier to locate conversation data when responding to a privacy request. If so, we will provide you with an electronic copy of any of your personal data we may use, which you are free to transmit to another data controller.

If you believe they are no longer relevant for the purposes for which they were collected, you also have the right to send us a request to erase your personal data and/or cease further dissemination of your personal data.

Furthermore, you are free to provide us with any corrections to your personal data.

We ask you when sending us one of the requests above, to provide us with a copy of a valid identification document. We shall consider your requests by comparing your privacy rights to the public interest in the availability of the data.

If we use your personal data on the basis of our legitimate interests, you may object if you have a specific reason why you do not want us to use your data in this way. We will stop the processing unless we have an overriding legal reason to continue or need the information for a legal claim.

Finally, you have the right to send us any motivated complaints about how we use your personal data and, if you so wish, file a complaint with the supervisory privacy authority.

8. Protection

We will treat all your personal data with the greatest possible care and that we shall not use the data for any purposes other than those that can be understood to be included in the purposes referred to above.

We have put all reasonable measures in place to ensure that personal data are protected against theft, misconduct and/or data breaches.

Access to personal data is limited to authorised personnel of ADE Foundation and authorised personnel of our (third party) processors and service providers who require access for the purposes described in this Privacy Statement. Such persons are subject to appropriate confidentiality and security obligations.

In all agreements regarding third party processors we oblige those parties to install at least the same level of protection and measurements protecting your personal data.

For the ADE Assistant, additional measures include separation of the conversation from direct account details, secure transmission, access restrictions, signed session tokens, rate-limiting, protected API credentials, monitoring and controls intended to reduce prompt-injection and unauthorised-output risks. As an additional data-minimisation measure, the content of user questions and generated answers is removed before regular technical logging and replaced by information about the length of the tekst.

9. Transfer to third countries

We may transfer data to a processor or third party based in a country outside of the EU or international organizations, but only if they provide appropriate measures to safeguard the protection of your data, and on condition that your rights and effective legal remedies are available. In such cases we will upon your request provide you with a copy of which data are transferred and to which third countries and under which level of protection.

When you use the ADE Assistant, the text you enter, the relevant conversation context and relevant ADE programme information are transmitted to OpenAI for the purpose of generating a response. Personal data processed through OpenAI may be transferred to and processed by OpenAI and its approved subprocessors in countries outside the European Economic Area, including the United States.

Such transfers take place only where a valid transfer mechanism under Chapter V GDPR applies. Where the relevant US recipient is covered by an applicable adequacy decision, by taking part in the Data Privacy Framework, the transfer is based on that adequacy decision. Furthermore, OpenAI uses the European Commission’s Standard Contractual Clauses and, where required, supplementary safeguards. You may contact us at [email protected] for more information about the applicable transfer mechanism or to request a copy of the relevant safeguards.

10. Minors

If you have not reached the age of 16 yet, your parents or legal representatives must be aware of this Privacy Statement before you are able to register and use the Website(s) and the Platform.

11. General

We reserve the right to modify this privacy and cookie policy and, as such, advise you to regularly check the most-up-to-date version of the Privacy Statement on the Website(s) or Platform to see if any changes have been made. If changes are of a fundamental nature, we shall clearly notify you of these changes, for example via e-mail.

The most recent changes to this Privacy Statement were made and published in September 2026.
