⚙ Data & look
Auto-save: your collection is stored in this browser whenever you change it. It survives refresh and reopening the file on the same device/browser — but browsers can wipe site data. Keep a backup file.
🗄️ Backup (important)
Export downloads a full JSON snapshot — missing stickers, spare counts, postal swaps, and theme. Import restores everything on another device or after clearing browser data. The yellow Backup button in the header does the same export.
