Questions, answered.
Everything about plans, privacy, the scanner, offline use, shared books and investments. A question not covered? A short message is enough.
Privacy
How can the scanner be private?
The whole scan runs on the phone. On-device text recognition reads the receipt, and parsers and matching rules written for Money Koi sort the items into the right categories — no external service reads it. With a connection, the app may look up a shop’s VAT number in the EU’s VIES register or open the link in a receipt’s QR code to fill in shop, date and total. Without an account, the booking and the photo stay on the phone. In a Cloud book, they are backed up encrypted to an EU server; the photo upload can be switched off.
Is the data encrypted?
Without an account, the book is stored on the phone, and Money Koi’s server never receives it. With Cloud, the sync to the EU servers is encrypted in transit and at rest. It is not end-to-end encrypted: the server works with the book itself to sync it, share it and show it in the web dashboard.
Is data sold or shared?
No. Financial data is never sold, shared or used for advertising. There is no ad network in the app.
What analytics are collected?
Usage statistics are only sent after a clear yes, go to Money Koi’s own server and never contain amounts, names or text. Crash reports are scrubbed of personal data, stored in the EU and can be switched off in settings.
Receipt scanner
Does anything need to be set up?
No. There’s nothing to download and nothing to switch on. The scanner works the moment the app is installed.
How accurate is the scan?
Accuracy depends on the receipt, so the app doesn’t just trust the result: it checks the sum of the extracted line items against the printed total and shows how well they match. Everything is reviewed before it’s saved.
What if the scan gets something wrong?
It can be fixed in the review screen. Merchant, date, total and every single line item can be edited before the transaction is created.
Can it handle long receipts?
Yes. Several photos of one receipt are processed together as a single transaction.
Does the scanner work offline?
Completely. Reading a receipt needs no server, so scanning works in airplane mode exactly as it does at home. In a Cloud book, the photo upload simply catches up once the connection is back.
Which stores does it know?
It has parsers written for SPAR, BILLA, LIDL, ADEG, HOFER, TEDI, Smyths and OBI, plus a general parser for every other store. The scanner is made for Austrian receipts: total, date and photo work on most of them, and items from other stores are a best guess that the review screen can fix. Receipts with the Austrian QR code are read especially fast.
Offline & sync
Does it work without internet?
Yes. Money Koi works fully without a connection — add, edit, delete and scan offline. Nothing is stuck behind a loading spinner.
When does it sync?
With Cloud, automatically in the background once the connection is back — a sync never has to be triggered by hand. Without Cloud, the book stays on the phone and nothing needs to sync.
Can several devices be used?
Yes, with Cloud. Signing in with the same account keeps the books in sync on every phone and tablet, and on the web.
What happens if the phone is lost?
With Cloud, signing in on the new phone brings everything back. Without Cloud, a backup file kept somewhere other than the phone does the same — restoring one is free on every plan.
Family sharing
How does family sharing work?
Money Koi has separate books. The personal book stays private, and a partner or the family can be invited into a shared one for the costs carried together. Shared books are part of Cloud: only the owner needs it, and everyone invited uses every feature inside the book at no cost.
Can others see personal transactions?
No. Only a shared book is visible to invited people. The personal book stays personal.
What roles are there?
Owner, admin and member — so the book owner decides who may only add bookings and who may manage the book.
How is someone invited?
With an invite link from inside the app. Switching between books afterwards takes one tap.
Investments
What can be tracked?
Precious metals and crypto at daily market prices, plus custom assets like property, vehicles or collectibles, valued by hand. Investments are part of Pro.
Can stocks and ETFs be tracked?
They can be added as a custom position and valued by hand. There are no automatic stock or ETF prices yet.
How is the return calculated?
Money Koi shows gains and losses and the real annual return (XIRR), which takes the timing of every purchase and sale into account.
Plans & pricing
What does Money Koi cost?
The budget book is free, with no time limit. Pro is a one-time purchase for the power features, and Cloud adds sync, shared books and the web — monthly, yearly or once. Current prices are on the pricing page.
What is free?
The whole budget book: bookings, quick add, the receipt scanner, budgets, income and savings goals, loans, recurring bookings, the Budget Book with its calendar, tags, the balance check, reminders and Android widgets. Free has no time limit and needs no account.
What does Pro add?
Analytics, the forecast, investments, shopping lists, an own Home layout and bottom bar, every export (CSV, PDF and ZIP) and backup files. Pro is paid once, works offline and needs no account.
What does Cloud add?
Everything in Pro, plus sync across devices, an automatic backup on EU servers, receipt photos in the cloud, shared books, up to three own books and the web dashboard. Monthly, yearly and lifetime Cloud all unlock the same.
Do invited people need to pay?
No. Everyone invited into a Cloud book uses every feature inside that book at no cost. In their own books, their own plan applies.
What happens when a plan ends?
Nothing is deleted or hidden. All data stays readable; only adding and editing in paid features locks. When Cloud ends, sync pauses and the phone keeps working on its own.
Is there a free trial?
Yes. Yearly Cloud starts with one month free, and the store shows when billing begins before anything is confirmed.
How is Cloud cancelled?
In the store account at Google Play or the App Store, at any time. Monthly and yearly Cloud renew until cancelled, and the plan stays active until the end of the period already paid for.
Can Pro be upgraded to Cloud?
Yes. Every Cloud plan is open to Pro owners, and Cloud lifetime comes as an upgrade with the Pro purchase already deducted.
Why is Cloud a subscription?
Sync, backup and the web run on servers that cost money every month. Paying once is still possible with Cloud lifetime.
What do early adopters get?
Every account created before 8 November 2026 keeps Cloud for life, at no cost and without a subscription.
Getting started
Which platforms are supported?
Android is available on Google Play. With Cloud, the web dashboard runs in any browser at my.moneykoi.com. An iPhone version is planned for the end of 2026.
Is an account needed?
No. Free and Pro work on one phone without an account, and Money Koi’s server never receives the book. An account is needed for Cloud, for joining a shared book and for the web dashboard.
Can the data be deleted?
Anytime. Deleting the account in settings removes the data from the servers too.
Which languages and currencies are supported?
The app is available in English, German and Japanese. Each book has one currency; several currencies in one book are planned for early 2027.
Still stuck?
Money Koi is built by one person, so every message lands directly with the developer.
