Privacy Policy

Last updated: 9 July 2026

This Privacy Policy explains how we collect, use, store and protect your personal data when you visit this website or contact us, and describes your rights under the EU General Data Protection Regulation (Regulation (EU) 2016/679, the “GDPR”) and Hungarian data protection law.

1. Who we are (Data Controller)

The controller responsible for your personal data is:

• Interien Kft.
• Registered seat: 1066 Budapest, Teréz körút 56-60, Hungary
• Tax number: 33064165-2-42
• Company registration number: 01-09-457202
• Email: [email protected]

We have not appointed a Data Protection Officer, as we are not required to do so. For any question about this policy or your personal data, please contact us using the email address above.

2. What personal data we collect

We collect only the data we need to respond to you and to run this website:

• Contact form data — your name, email address, company name (optional) and the content of your message.
• Booking data — if you book a meeting through our scheduling link, your name, email address and any details you provide when booking.
• Technical data — when you visit the site, our hosting provider automatically processes limited technical data in server logs, such as your IP address, browser and device type, and the date, time and pages requested. This is used to operate and secure the website.

We do not collect special categories of data, and we do not carry out automated decision-making or profiling.

3. Why we process your data and our legal basis

• To respond to your enquiry and take steps toward a possible engagement — legal basis: our legitimate interests (Art. 6(1)(f) GDPR) and, where relevant, steps taken at your request prior to entering into a contract (Art. 6(1)(b) GDPR).
• To schedule and hold meetings you book — legal basis: our legitimate interests and pre-contractual steps (Art. 6(1)(f) and 6(1)(b) GDPR).
• To operate, maintain and secure the website — legal basis: our legitimate interests in a functioning, secure service (Art. 6(1)(f) GDPR).
• To comply with legal obligations — where applicable, legal basis: compliance with a legal obligation (Art. 6(1)(c) GDPR).

4. Cookies

This website uses only strictly necessary, technical processing required to serve the pages to you. We do not use analytics, advertising or tracking cookies, and we do not embed third-party trackers. Because of this, no cookie-consent banner is required. If we introduce analytics or marketing cookies in the future, we will update this policy and ask for your consent beforehand.

5. Who we share your data with (processors)

We do not sell your personal data. We share it only with service providers who process it on our behalf and on our instructions, under a data processing agreement:

6. International data transfers

netcup GmbH processes data within the European Union. Calendly LLC and Interien US LLC are located in the United States, so using their services involves transferring your personal data outside the European Economic Area. These transfers are protected by the European Commission's Standard Contractual Clauses (SCCs), together with appropriate additional safeguards. Calendly also participates in the EU-US Data Privacy Framework where applicable. You can request more information or a copy of the relevant safeguards by contacting us.

7. How long we keep your data

We keep contact-form and enquiry data only for as long as needed to handle your enquiry, and we delete it within 12 months afterwards, unless a longer retention period is required by law or to establish, exercise or defend legal claims. Technical server logs are kept only for a short period for security and troubleshooting purposes.

8. Your rights

Under the GDPR, you have the right to:

• access the personal data we hold about you;
• request rectification of inaccurate or incomplete data;
• request erasure of your data (“right to be forgotten”);
• request restriction of processing;
• object to processing based on our legitimate interests;
• data portability, where applicable;
• withdraw consent at any time, where processing is based on consent (without affecting prior processing).

To exercise any of these rights, email us at [email protected]. We will respond within one month.

9. Right to lodge a complaint

If you believe we have handled your personal data unlawfully, you may lodge a complaint with the Hungarian supervisory authority:

• Nemzeti Adatvédelmi és Információszabadság Hatóság (NAIH)
• Address: 1055 Budapest, Falk Miksa utca 9-11, Hungary
• Postal address: 1363 Budapest, Pf. 9
• Phone: +36 1 391 1400
• Website: naih.hu

You also have the right to seek a judicial remedy before the competent court.

10. Data security

We apply appropriate technical and organisational measures to protect your personal data against unauthorised access, loss, alteration or disclosure. No method of transmission or storage is completely secure, but we take reasonable steps to safeguard your information.

11. Children

This website is intended for businesses and is not directed to children. We do not knowingly collect personal data from children under the age of 16.
