Privacy notice

Controller

Stefan Junk Holding UG, Sterkraderstr. 24, 13507 Berlin, Germany. Represented by Stefan Junk. Privacy contact: [email protected].

Firebase Hosting

This static website is delivered through Google Firebase Hosting. Google may process technical request data such as IP address, requested URL, timestamp, browser information, and security signals to deliver and protect the service. Our legal basis is our legitimate interest in secure, reliable publication under Article 6(1)(f) GDPR.

Optional Firebase Analytics

Firebase Analytics is loaded only after you select Allow analytics. Before that choice, the Analytics SDK is not initialized and no Analytics page view is sent. If allowed, Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland processes page URL, page title, referrer, browser and device information, approximate location, and analytics identifiers. We do not send email addresses, form values, or calculator inputs.

The legal basis is consent under Article 6(1)(a) GDPR and Section 25(1) TDDDG. Event-level data is retained for no longer than 14 months under the Analytics property controls. Google may use approved safeguards, including standard contractual clauses and an applicable adequacy framework, for transfers outside the EEA.

You can decline without losing site functions. Use the persistent Privacy settings button to withdraw or change the choice; withdrawal stops future collection and does not affect prior lawful processing.

No newsletter or email subscription

RoamSignal runs no newsletter or email subscription, and this site has no contact form, account, advertising profile, or checkout. Email sent voluntarily to our published address is used only to respond and is retained only as needed for that correspondence and legal obligations.

External provider links

Provider links open third-party websites. Those providers receive normal request information and apply their own privacy notices. Current links are non-affiliate and RoamSignal does not send a user identifier in them.

Your rights

You may request access, rectification, erasure, restriction, portability, or object to processing where applicable. You may withdraw consent at any time. Contact [email protected]. You may also complain to the Berlin Commissioner for Data Protection and Freedom of Information or another competent supervisory authority.
