クーポンキーパー

"3 yen off next time" coupons at gas stations, "exchange vouchers" at convenience stores—coupons attached to receipts are often lost along with the receipt, or their expiration dates are forgotten, leading to missed opportunities to use them.

"Coupon Expiration Memo" is an app that saves and manages these receipt-based time-limited coupons, including their expiration dates. Membership barcodes (point cards) without expiration dates can also be saved in the same app.

■ For those who:
・Often lose receipts with coupons
・Sometimes realize coupons have expired
・Want to organize membership cards in their wallet

■ Main Features

【Scan and Save Barcodes】
Scan barcodes and QR codes with your camera and save them directly within the app. For coupons that cannot be scanned, you can also save them as images. Supports both QR codes and one-dimensional barcodes (EAN / Code128, etc.).

【Register Expiration Dates and Automatically Sort by Expiration Date】
Register expiration dates for coupons, and they will be automatically sorted by the nearest expiration date. The list is clearly displayed, divided into "Expiring Soon," "Expiring," and "Permanent Cards." You can see at a glance which cards are nearing their expiration date. Entering the expiration date is optional, so you can save membership cards without expiration dates as well.

【Full-Screen Display & Automatic Brightening at the Register】
Simply tap a card to display the barcode in full screen. While displayed, the screen brightness automatically increases to maximum, making it easier for the register scanner to read. Swipe left or right to quickly switch to the next card.

【Expiration Reminder Notification】
You will receive a notification the day before and on the day of the expiration date. This prevents you from accidentally forgetting to use your coupons.

【Used/Expired Coupons in History】
Used and expired coupons are moved to the history. You can restore or delete them later.

■ Privacy Policy
All data is stored on your device; no cloud transmission or account registration is required. Receipt images are not displayed in the list; they are only displayed when presenting a coupon.

■ Terms of Use
This app is designed to support the storage and presentation of your coupons. This coupon is not intended for resale, transfer to third parties, or repeated use. You may be required to present the original coupon for individual campaigns. Please check the terms and conditions of each store and campaign before use.
