About this app
Keep track of deadlines. The receipt as proof.
Kvarvero is the app for everyone who wants to stay on top of warranty and guarantee issues. Because the real value isn't in the receipt itself, but in the deadline behind it – and that deadline slips away quietly while the receipt fades into obscurity in a drawer.
IT'S THAT EASY
Photograph the receipt, enter the purchase date – done. Kvarvero calculates the deadlines, sorts your entries by the next expiration date, and reminds you in good time before a deadline expires. If a defect occurs, you have the proof immediately at hand.
THE REAL REMAINING VALUE
In Germany, you have a two-year statutory warranty against the retailer for every new purchase. For the first twelve months, it's presumed that a defect already existed at the time of purchase – the retailer is responsible. After that, the situation reverses. Kvarvero makes this turning point visible: What looks like "2-year warranty" on the box is actually a remaining period that changes month by month.
AT A GLANCE
• Green: approaching, red: running out, gray: expired – the status is always clear.
• "1 deadline approaching" or "12 deadlines expired" – you see immediately what's coming up.
• Sorted by the next expiration date, so the important ones are at the top.
RECEIPTS YOU CAN FIND AGAIN
• Scan receipts and invoices – the text becomes searchable.
• Import from photos and files (PDF, JPEG, PNG, HEIC).
• Transfer receipts directly from other apps to Kvarvero.
• Claims documents as PDFs – your proof, all in one place.
ON YOUR DEVICE – NOWHERE ELSE
• No account, no registration, no ads, no tracking.
• Your receipts stay locally on your device.
• Optional backup to your own cloud – you stay in control.
SET UP ONCE, ALWAYS READY
No subscription, no ongoing costs. Kvarvero runs silently in the background and only notifies you when a deadline is important.
WHO IS IT FOR? For anyone who buys electronics, household appliances, tools, or furniture and doesn't want to be left empty-handed if something goes wrong. It's not a tax tool or an accounting export – it's an app that does one thing right: keeping track of deadlines and providing proof of purchase.
Note: Kvarvero is an organizational app and does not provide legal advice.
