Privacy information.

This notice explains how Mercury International GmbH handles personal data when you use this website or contact the company.

1. Controller

Mercury International GmbH (“Mercury”, “we”, “us” or “our”) is the controller responsible for the processing described in this notice. Its registered office is Sinserstrasse 65, 6330 Cham, Switzerland.

Privacy and other enquiries can be submitted through the contact form.

2. Scope and applicable law

This notice covers personal data processed through this corporate website and related business correspondence. Swiss data-protection law applies. The EU or UK GDPR may also apply where its territorial requirements are met.

3. Website access and hosting

When you visit the website, technical connection data is processed to deliver and secure it. This may include IP address, date and time, requested path, referrer, browser or device information, and response status.

The website is hosted by Render Services, Inc. (United States). The production service is deployed in Render’s Frankfurt region in Germany. Render and its subprocessors may also process technical data in the United States or other countries, subject to applicable contractual and transfer safeguards.

4. Contact form

The form collects your name, work email, optional company or organisation, reason for contact, and message. Mercury uses this information to assess and respond to your enquiry, take requested pre-contractual steps, manage relevant business correspondence, and protect the form from misuse.

Form messages are transmitted through Resend, an email-delivery service operated by Plus Five Five, Inc. (United States), and received in a mailbox provided to Mercury by Google Ireland Limited (Ireland). Google group companies and subprocessors may also process message and technical data in the United States or other countries. Provider processing is subject to applicable contracts and transfer safeguards.

Please do not submit passwords, payment details, sensitive personal data, or confidential documents through a first-contact message.

Providing information is voluntary. Your name, work email, reason for contact, and message are required so Mercury can receive and respond to the enquiry; the company or organisation field is optional. The form cannot be submitted if required information is omitted.

5. Form security and cookies

General information pages do not set cookies. When you open the contact form, Mercury sets one short-lived, first-party security cookie that is strictly necessary to validate the form and reduce automated misuse.

You can block or delete the cookie through your browser settings, but the contact form cannot be submitted without it. A privacy request can instead be sent by post to Mercury’s registered office. The cookie is not used for advertising, analytics, or profiling.

Because the website uses no non-essential cookies or similar browser storage, Mercury does not display a consent banner. If optional storage or tracking technology is introduced later, it will remain disabled until any required information and consent choices are available.

Mercury also applies limited, temporary rate controls using one-way identifiers; form contents and raw IP addresses are not written to application logs by the contact handler.

6. Analytics and marketing technologies

Mercury does not use advertising trackers, behavioural analytics, non-essential cookies, local storage, or session storage on this website. The website does not build visitor profiles for marketing purposes or use website and contact data for solely automated decisions that produce legal or similarly significant effects.

7. Purposes and legal grounds

Under Swiss law, Mercury processes personal data in accordance with the applicable principles of lawfulness, good faith, transparency, proportionality, purpose limitation, and security. Where the EU or UK GDPR applies, Mercury relies on the following legal grounds as relevant:

Pre-contractual steps or contract: responding to an enquiry or taking steps you request in connection with a possible business relationship.
Legitimate interests: providing and securing the website, preventing misuse, maintaining reliable services, and managing business relationships and correspondence, provided those interests are not overridden by individual rights.
Legal obligations: retaining or disclosing information where applicable law requires it.
Consent: only where Mercury specifically asks for consent for a separate purpose; consent may be withdrawn at any time without affecting earlier lawful processing.

8. Recipients and international processing

Data may be accessed by authorised Mercury personnel, the providers identified above, and professional advisers where necessary and subject to appropriate confidentiality obligations. Where data is disclosed or made available in a country without an adequate level of data protection, Mercury relies on recognised contractual clauses or other safeguards required by law, unless a statutory exception applies.

9. Retention

Technical security data is retained only for the period needed to operate and protect the service. General enquiries are ordinarily retained for up to 24 months after the last substantive interaction. Relevant records may be kept longer where needed for an ongoing business relationship, legal duties, the establishment or defence of claims, or documented corporate records.

10. Security

Mercury applies reasonable technical and organisational measures appropriate to the nature of the data and the associated risks. These include encrypted transport, server-side validation, access controls, rate controls, and restricted handling of contact details. No method of internet transmission or storage can be guaranteed absolutely secure.

11. Your rights

Depending on the law that applies, you may have rights to information, access, correction, deletion, restriction, objection, or data portability, and to withdraw consent where processing relies on consent. Submit a privacy request through the contact form or in writing to Mercury’s registered office; proportionate information may be required to verify identity.

You may report a concern to the Swiss Federal Data Protection and Information Commissioner (FDPIC). Where EU or UK data-protection law applies, you may also lodge a complaint with the competent supervisory authority.

12. Changes

Mercury may update this notice when the website, providers, or legal requirements change. The date above identifies the current version.
