Mastchain Privacy Policy
Effective date: 6 December 2025
This Privacy Policy explains how Mastchain, a product of Worldwide AIS Network ApS, collects and processes personal data when you visit our website or interact with our online services. We recognise the importance of protecting personal data and are committed to processing it lawfully, fairly, and transparently in accordance with the EU General Data Protection Regulation and applicable Danish data protection law. By using our website, you confirm that you have read and understood this Privacy Policy.
The data controller responsible for the processing of personal data is Worldwide AIS Network ApS, CVR number 45911748, with its registered office in Copenhagen, Denmark. Mastchain is operated as a product of Worldwide AIS Network ApS. References to “we”, “us”, or “our” in this policy refer to Worldwide AIS Network ApS. You may contact us regarding data protection matters at contact@worldwideais.org.
We process personal data that you provide directly when you contact us, send enquiries, subscribe to updates, or otherwise communicate with us through the website. This may include your name, email address, contact details, and the content of your communications. In addition, we automatically collect certain technical and usage data when you visit the website. This includes IP address, approximate geographic location derived from the IP address, browser type and version, operating system and device information, pages visited, referring pages, time spent on the site, and general interaction patterns. This data is collected through server logs, cookies, and similar technologies.
Personal data is processed for clearly defined purposes and only when a lawful basis exists. We process data in order to respond to enquiries and communications based on our legitimate interest in engaging with users and operating our business. Technical and usage data is processed to ensure the functionality, stability, and security of the website, which is also based on our legitimate interests. Where we analyse website usage or measure performance through analytics tools, processing takes place only with your consent. Marketing communications are sent only when you have actively chosen to receive them and are based on your consent. You may withdraw consent at any time, and such withdrawal does not affect the lawfulness of processing carried out prior to withdrawal.
Our website uses cookies and similar tracking technologies. Some cookies are strictly necessary to enable core website functionality and cannot be disabled. Other cookies are used for analytics and marketing purposes and are set only after you have given explicit consent through our cookie banner. We use third party tools such as Google Analytics, Google Tag Manager, and Meta Pixel to understand how visitors interact with the website and to measure performance. These tools may collect technical and behavioural data such as IP address, device information, and usage patterns. Continued browsing alone does not constitute consent, and non essential cookies are not set before consent has been given. You can change or withdraw your cookie preferences at any time through the cookie settings on the website or through your browser settings.
We do not sell personal data. Personal data may be shared with trusted service providers who act as data processors on our behalf, such as hosting providers, analytics providers, and communication or technical service providers. These processors process personal data only in accordance with our instructions and under written data processing agreements that ensure appropriate security and confidentiality. Personal data may also be disclosed where required by law, in response to legal proceedings, or where necessary to protect our rights or the safety of others.
Some of our service providers process personal data outside the European Union or European Economic Area, including in the United States. Where such transfers take place, we ensure that appropriate safeguards are in place, including the use of Standard Contractual Clauses approved by the European Commission and, where necessary, additional technical and organisational measures. Information about these safeguards may be requested by contacting us.
Personal data is retained only for as long as necessary to fulfil the purposes for which it was collected. Enquiry and correspondence data is typically retained for up to twelve months, analytics data is retained in accordance with the settings of the relevant service provider and typically for no longer than fourteen months, and marketing subscription data is retained until consent is withdrawn. Data may be retained for longer periods where required by law or where necessary for the establishment, exercise, or defence of legal claims. When data is no longer required, it is securely deleted or anonymised.
You have rights under the GDPR in relation to your personal data. These include the right to access your data, to have inaccurate data corrected, to request deletion, to restrict or object to processing, to receive your data in a portable format, and to withdraw consent at any time where processing is based on consent. Requests may be submitted by contacting us at contact@worldwideais.org. We may request verification of your identity before responding. Requests are handled without undue delay and no later than one month after receipt, unless an extension is permitted under applicable law.
You also have the right to lodge a complaint with the Danish Data Protection Authority, Datatilsynet, if you believe that the processing of your personal data violates applicable data protection law. Information about Datatilsynet and complaint procedures is available at www.datatilsynet.dk.
Our website is not directed at children under the age of sixteen, and we do not knowingly collect personal data from children. If we become aware that personal data relating to a child has been collected without appropriate consent, we will delete it without undue delay.
Our website may contain links to external websites operated by third parties. We are not responsible for the privacy practices or content of those websites, and we encourage users to review the privacy policies of any external sites they visit.
This Privacy Policy may be updated from time to time to reflect changes in legal requirements, technology, or our processing activities. Any updates will be published on this page with a revised effective date. Continued use of the website after an update constitutes acceptance of the revised policy.
If you have questions, concerns, or requests relating to this Privacy Policy or the processing of personal data, you may contact us at contact@worldwideais.org.
