Cookie and Local Storage Policy
Last updated: October 2026
1. What are cookies and local storage?
A cookie is a small text file that websites store on your browser or device upon access. Cookies manage user sessions and remember essential technical preferences (such as language). In addition, local storage (localStorage) allows functional preferences to be stored privately directly inside your browser without sending unnecessary personal data to servers.
2. Technologies we use at Viuu
At Viuu we adhere to privacy by design and data minimization principles. For this reason, we only utilize strictly essential technical and functional technologies:
- Technical authentication cookies: Essential for securely signing in via Supabase and managing your organization's calendars.
- Preferences cookies and storage: Allow remembering the interface language (Catalan, Spanish, or English), preferred subscription client (Apple Calendar or Google Calendar), and your chosen agendas in "My Viuu / La Meva Tria".
- Zero advertising or commercial tracking cookies: We use no profiling cookies, social media tracking pixels, or cross-site tracking tools (zero advertising third parties such as Google Ads or Meta).
