What the app stores
BestWhen stores the event title, invited names, and the availability blocks each person submits. Times are stored in UTC so they can be shown correctly in each viewer's local time zone.
How identity works
There are no accounts or passwords. Your selected name is remembered on your device using local browser storage. The private event link acts as access to that calendar, so only share it with people you trust.
Who processes the data
The app is hosted by Vercel and event data is stored with Supabase. BestWhen does not currently use advertising, sell personal information, or run third-party behavioral analytics.
Control and deletion
Participants can edit or clear their own availability. For help removing an event, contact the organizer who shared your link.
Keep it group-safe
Do not enter sensitive personal information. Anyone with the event link may be able to view the names and availability on that calendar.
