Two roles: this website, and the EZ2Stay platform
This policy covers two different things, because they have different legal roles under data protection law.
First, ez2stay.com the marketing website: when you browse it, EZ2Stay SRL is the controller of the data described below (analytics, consent choice, locale, server logs).
Second, the EZ2Stay platform that hostels run their front desk on: when a guest completes online check-in, EZ2Stay SRL acts as processor on behalf of the hostel (the controller), which sets the retention and access rules for its own guests' data. A Data Processing Agreement governs this relationship; the DPA page ships separately.
