Coupon Ledger

Track coupon expiry without a cloud account

Keep the coupon facts you already know in one local ledger, without merchant lookup, cloud sync, or an account.

Use it when

You need a manual record of coupon labels, expiry information, and savings amounts you entered.

How it works

1. Add a coupon-use record and the details you know.
2. Edit or delete records as needed.
3. Export an Android-compatible schema-v1 JSON backup for a portable copy.

Privacy boundary

Store names, labels, amounts, expiry details, and backups stay in browser-local storage or your downloaded file. The app does not verify offers or query merchants.
