Never miss a return deadline. Your money comes back.
Kumbak keeps track of returns, refunds and warranties after every purchase and tells you what to do, and by when, so you don't lose money by missing a deadline.

How it works
Add your purchases
Scan the receipt, share the PDF or text of the order e-mail, import your order history from the store, or enter it by hand.
Kumbak works out the deadlines
Return window, refund and warranty, based on the shop's policy and the law of your country, and always with the reason shown.
Act in time
Reminders before money is at stake: before a return window closes, before a guarantee ends and when a refund is late.
Your data stays on your phone
No account and no password. Your purchases are not stored on Kumbak's servers. Premium backups are encrypted on your phone before they go to your own Google Drive.
