Gifticon Keeper: Expiry Alert

Got gifticons (mobile gift certificates) from Kakaotalk Gift or other services buried somewhere in your gallery, quietly expiring?

Gifticon Keeper organizes your gifticon images in one place and tracks their expiry dates with clear D-day badges. It's a pure local storage tool with no trading, selling, or cash-conversion features — lightweight, and no sign-up or login required.

■ How it works
1. Pick a gifticon image from your gallery (uses Android's system Photo Picker — only the single photo you pick is shared with the app, no full gallery access needed)
2. Enter brand (12 presets + custom entry), item name, amount (optional), and expiry date
3. Save, and it's automatically sorted by nearest expiry on the home screen

■ Key features
- D-day badges in 3 colors: safe (mint), approaching (amber), urgent (red) — check status at a glance
- Brand category filter chips, plus Active / Used / Expired segments
- Present your barcode at checkout instantly: the detail screen shows a full-screen image and auto-boosts screen brightness to the max
- Mark as used, extend expiry (for reissued gifticons), pinch-to-zoom
- Expiry reminders: local notifications at 9 AM on D-7 / D-3 / D-1 (toggle each in Settings)
- Stats: this month's and all-time "saved" (used) vs. "missed" (expired) amounts, plus usage breakdown by brand
- Korean/English language support, dark mode support

■ Privacy-friendly by design
- No sign-up, no login, no trading/selling/cash-conversion features
- Selected gifticon images and info are stored only on your device — never sent to any server
- Deleting the app deletes the data with it

Never miss a gifticon's expiry date again.
