The safest option of crypto storage is storing and using private keys on a completely (and always) offline device - it is called cold storage.
One way to achieve this is buying a hardware wallet - however, this costs money and has some other disadvantages
We propose another option to achieve this, a cold wallet consisting of 2 separate parts of software
Context
Our wallet consists of 2 parts of software:
Offline client - cross-platform web-page - it is designed to work in a separate, completely offline OS. Creates and signs transactions with private key
Online client - mobile application, sends transactions to the network. Allows to track multiple addresses, watching their balance and transaction history

Similar functionality is available in the oldest and one of the most popular Ethereum wallets - https://www.myetherwallet.com.
Functionality of our wallet is even better, because it allows to transfer transaction data with QR code, instead of a USB stick in both directions
As for Bitcoin, similar functionality is available for example in one of the oldest wallets - electrum
