Big Shelf

Big Shelf is a fully offline Android app for reception desks, dormitories, offices, and small pickup counters. Record who each parcel belongs to, where it sits on the shelf, how long it can stay, and when it was handed over — without accounts, ads, or internet.

Key features:
• Accept, edit, search, pin, issue, and reopen parcel records
• Search by recipient, tracking number, or shelf code
• One active parcel per tracking number (enforced locally)
• Label photos via system camera or Photo Picker
• Storage deadline calculation with clear rules and limits
• Immutable handover history on device
• Versioned ZIP backup export/import with preview and conflict checks
• Phone and tablet layouts, light/dark themes, optional Dynamic Color

Privacy by design:
• No login or cloud sync
• No INTERNET permission, analytics, or advertising
• All data stays on the device until you export a backup

Ideal for front desks that need a simple shelf-and-pickup log without a server.
