Kaucjoner

Stop losing deposit return coupons in your wallet or trash. Kaucjoner scans, stores, and reminds you before any deposit return coupon expires.

Kaucjoner turns every paper deposit-return receipt into a coupon you'll actually remember to use.

In most countries, returning bottles and cans gets you a paper coupon with a barcode and a 30-day clock that's easy to lose track of. Kaucjoner keeps every coupon scanned, organized, and ready to use before it expires.

HOW IT WORKS Point your camera at the receipt. Kaucjoner reads the barcode automatically and assigns shop name from your current location, so there's nothing to type. Save it, and the coupon is ready to show at the register next time you shop.

STAY ON TOP OF EXPIRY DATES Every coupon shows its issue date, expiry date, and current status at a glance. Mark coupons as used once redeemed, and get a local reminder before one is about to expire, so a copupon never quietly disappears.

BUILT FOR HOW YOU ACTUALLY SHOP

• Fast barcode scanning, no manual entry
• Automatic 30-day expiry calculation, editable if needed
• Store tagging, so you know where each coupon came from
• Expiry reminders generated entirely on your device — no network access, no data leaving your phone

PRIVACY BY DESIGN Kaucjoner doesn't need an account, a server, or your data. Coupons stay stored on your device, and notifications are generated locally. What's in the app stays in the app.

Whether you've got one coupon or a drawer full of crumpled receipts, Kaucjoner makes sure none of them go to waste.
