Kayio
Never miss a return deadline again.
Kayio files your purchases from a receipt photo or an order confirmation, reads the retailer, price and deadlines, and reminds you in time – before a return window or warranty runs out.

How it works
Three ways in, one vault, reminders in time.
Photograph the receipt
Snap a till receipt or invoice, or upload it as a PDF. Kayio reads the retailer, items, price and purchase date.
Forward the order email
Send order confirmations to your personal Kayio address, or set it up once as a Gmail filter. New orders then land in the vault by themselves.
Deadlines are read for you
Return window and delivery date come from the receipt or the email. If something is missing, Kayio leaves the field empty instead of guessing – you fill it in with a tap.
Get reminded in time
7, 3 and 1 day before a return deadline and on the last day; before a warranty ends, in its final month. By email or push. Keeping it or returning it? One tap, and the reminders stop.
Automatic recognition can be wrong. Kayio shows you everything to check before filing, and return deadlines taken from retailer policies are marked as estimates.
What Kayio keeps in view for you
Everything you still need after the purchase – in one place.
Return deadlines
Counted from the delivery date, with reminders 7, 3 and 1 day before and on the last day. For over 200 retailers Kayio knows the usual return terms.
Return windows by retailerWarranty and statutory rights
Your country's statutory period is entered automatically; a longer manufacturer warranty takes one tap.
Warranty documents
Receipt photo, purchase details and order documents as one PDF for a claim – created in seconds.
Find everything again
Search your purchases by item or retailer. Receipts, order emails and invoices stay fully readable.

Frequently asked questions
What does Kayio cost?
Using Kayio is free: filing purchases, return reminders and the family vault, with no cap. Five warranty reminders per vault are included.
Which receipts can I file?
Till receipts and invoices as a photo or PDF, order confirmations and shipping emails by forwarding – or you enter a purchase by hand.
How does Kayio know the return deadline?
If it is printed on the receipt or in the order email, Kayio takes it from there. Otherwise Kayio shows the retailer's usual terms from a maintained table – marked as an estimate. Your own entry always wins.
What if Kayio reads something wrong?
Before filing you see every recognised detail and can tap to change it. If something is missing, the field stays empty instead of Kayio guessing.
Do I need the app?
No. Kayio runs fully in the browser, on the phone too. The Android app adds push notifications and the camera right inside the vault.
How does the family vault work?
You invite up to four adults by email. Shared purchases are seen by everyone, private ones only by you. If someone leaves the vault, they take their private purchases with them; shared ones stay.
Where is my data stored?
Database and files are in Frankfurt. For automatic recognition, receipts are transmitted to an AI service; details and legal bases are in the privacy policy.
Is Kayio legal advice?
No. Kayio helps you keep deadlines in view. Whether you have a right to return or a warranty claim in a given case depends on the law and the retailer's terms.
Your next purchase has a deadline. Kayio remembers it.
