Features

Everything a wallet needs, nothing else.

Create or restore

Create a new wallet in seconds, or restore one you already have with its recovery key. Your key is made on your phone and stays there.

Send in milliseconds

Enter an address and an amount on the keypad, add a note if you like, and tap Send. The payment is confirmed in milliseconds.

Receive and scan

Show a QR code with your address and, if you want, an amount. Scan it in the app or with the phone’s own camera to open Send already filled in.

Money just arrives

Payments to you are collected automatically, and your balance and activity update live as blocks are confirmed.

See your own chain

My chain shows your wallet’s blocks, linked one after another, with the newest glowing gold.

Names for addresses

Give addresses names like “Mom” or “Coffee shop”. They are kept only on your phone.

Getting started

Three steps to your first payment.

  1. 01

    Get the app

    Download the OneEur wallet for iOS or Android from [where to get it].

  2. 02

    Create your wallet

    Tap Create wallet and choose a 6-digit PIN. Your key is made on the phone and encrypted with the PIN.

  3. 03

    Back up your recovery key

    In Settings, tap Copy recovery key and keep it somewhere safe and offline. It is the only way to restore your wallet.

Safe by design

Locked with your PIN.

Your key stays on the phone

The wallet’s secret is encrypted with your PIN and stored in the iOS Keychain or Android Keystore. The app asks for the PIN when it opens, after a minute in the background, and before anything sensitive. More about security →

Removing the app removes the wallet

Uninstalling the app or tapping Remove wallet deletes the key from the phone. Make sure your recovery key is backed up first.

Privacy policy

No account, no tracking.

This policy covers the OneEur wallet app for iOS and Android. Last updated 6 October 2026.

What we don’t collect

The app has no sign-up and never asks for your name, email, phone number or contacts. It has no ads, no analytics, no crash reporting and no third-party trackers, and it sends no device identifiers.

What stays on your phone

Your wallet’s secret key, encrypted with your PIN and kept in the iOS Keychain or Android Keystore. Your PIN is never stored or sent. Names you give to addresses and a local copy of your chain are also kept only on the phone. None of this is sent to us or anyone else.

What the app sends to the network

To show your balance and make payments, the app connects to the OneEur gateway at gateway.oneeur.com over an encrypted connection. It asks for the blocks of your address and sends payments you sign: the sender and receiver addresses, the amount, your public key, the signature and the memo, if you add one. As with any internet connection, the gateway sees your IP address in order to reply.

Payments are public and permanent

Every confirmed block, including addresses, amounts and memos, is copied to every chain holder and can be seen by anyone in the explorer. Addresses are not linked to your name by us, but anyone you pay or who pays you knows your address. Blocks cannot be changed or deleted by anyone, including OneEur. Never put private information in a memo.

Camera and clipboard

The camera is used only to scan payment QR codes, and only after you allow it. Images are read on the phone and are never saved or sent. The app reads the clipboard only when you tap Paste, and writes to it only when you tap Copy.

Deleting your data

Tapping Remove wallet or uninstalling the app deletes the key, your address names and the local chain copy from the phone. Blocks already on the chain stay there, because the network has no way to remove them.

Changes and contact

If this policy changes, we will update this page and the date above. Questions about privacy: [contact email].
