Group and activity data live in Room on device; the APK has no network permission—no login or backend for daily use.
Who needs to install the app?

Can multiple people sync or edit together?
No. Group Matters is single-device offline software—no accounts, server, or multi-device sync. Use zip backup / restore to move to a new phone.
