RH Aero Systems – Website Data Protection Declaration

(Last updated 21 July 2025)

RH Aero Systems (“RH Aero,” “we,” “our,” “us”) unites the aerospace‑tooling heritage of Rhinestahl and HYDRO. Protecting your personal data has always been central to both companies’ cultures; this declaration explains how we honour that commitment on the RH Aero website.

Important: This declaration applies only to rhaero.com. When you follow a link to a social‑network page or any other external site, that provider’s privacy notice applies.

3  Transfer of Personal Data to Third Parties

  • Linked offers & social plug‑ins (LinkedIn, Facebook, Instagram, X/Twitter) are inactive until you click them. Thereafter each platform’s policy applies; data may transfer outside the EEA.
  • Service providers (e.g. hosting, IT security, marketing) receive data only as needed under data‑processing agreements. Details appear in our consent‑management banner.

Essential cookies load automatically. All others load only after you grant consent in our banner or through browser settings. Disabling cookies may restrict functionality.

5  Email and Contact Forms

Emails sent to info@hydro.aero or other published addresses—and data from contact or enquiry forms—are stored solely to handle your request. Once the conversation (or any resulting contract) is complete, related data is erased unless commercial or tax laws require retention (up to ten years).

You may object to storage at any time by writing to revoke@hydro.aero; we will then delete your data unless legal obligations prevent us from doing so.
