The deposit that stays in your pocket
In Poland every bottle and can carries a deposit, and the receipt that proves it has an expiry date and a talent for disappearing. Buttelkowy keeps every voucher together, shows the total up front and reminds you before anything expires. At the till it takes one tap.
Shop loyalty cards live in the same app — no more scrolling your photo gallery in the queue.
Your data stays with you
Vouchers, photos and cards stay in your phone’s storage. There is no account and no sign-in; the only thing the app sends out is an anonymous report when something breaks. You can save a backup to a single file whenever you like.
