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.

2.1 Website Access Logs
Data element | Purpose | Retention |
Browser & OS, date/time, page requests, referrer/next URL, file names & sizes | Site delivery & optimisation | Session |
IP address & ISP | Security (attack detection/fraud prevention) | 7 days |
2.2 Data You Provide
We store additional personal data only when you supply it—for example via registration forms, chats, enquiries, surveys, competitions, or contracts—and only where permitted by your consent or applicable law.
2.3 Legal Bases
Situation | GDPR basis |
Temporary log files | Art. 6 (1)(f) – legitimate interest (site security) |
Enquiries, contracts, support | Art. 6 (1)(b) – contract initiation/fulfilment |
Statutory record‑keeping | Art. 6 (1)(c) |
Non‑essential cookies, analytics, marketing | Art. 6 (1)(a) – your consent |
You are not legally obliged to provide data, but some site functions may be unavailable without it.
2.4 Deletion
Data is erased once its purpose has been fulfilled, unless legal retention duties apply.
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.
4 Cookies & Similar Technologies
We use HTML cookies, Web Storage, Microsoft Clarity scripts, and comparable tools to:
- remember language or preference settings,
- analyse traffic (Google Analytics 4, Lead Forensics, SalesViewer®),
- optimise campaigns via Google Tag Manager.
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.
6 Newsletter
Subscription data: title (optional), name (optional), company (optional), email address (mandatory), timestamp.
With your consent we record open rates, click paths, and on‑site behaviour to personalise content.
Unsubscribe at any time via the link in each newsletter or by emailing revoke@hydro.aero.
