Swiss UID register: Proton AG (Aktiengesellschaft), seat Plan-les-Ouates, Canton GE, status active. The DPA gives the company ID CHE-354.686.492. Contracting entity.
Oberste Muttergesellschaft
Proton Foundation (CH)
Proton says its primary shareholder is the Proton Foundation, a Swiss non-profit in Geneva; employees hold most other shares. No percentages or register entry found, so this is the named main holder, not a verified ultimate parent.
Zugriff durch Drittstaatenrecht teilweise
Beruht auf derselben Eigentümerkette wie der Rechtsraum.
Datenstandort nicht erfüllt
Speicherung standardmäßig in der EU
Nein
Servers are 'exclusively located in Switzerland, Germany or Norway', owned and operated by Proton or its subsidiaries. Norway is EEA, but Switzerland is not EU/EEA, and no EU/EEA-only option was found.
Verarbeitung standardmäßig in der EU
Unbekannt
Looked at Drive privacy policy, group privacy policy and DPA. Servers are in CH, DE and NO; no page states where processing happens. The DPA allows transfers to CH, EU or adequate countries 'to the extent possible'.
Regionen
Switzerland, Germany, Norway
Older Proton pages list only Switzerland and Germany.
Unterauftragsverarbeiter erfüllt

Ja
Group privacy policy s.4 lists processors with locations; the Drive policy names none. The text names Calendly and HubSpot, missing from the s.4 list. DPA: general authorisation, updates via the privacy policy.
