# Polkadot Vault Wallet \[Legacy]

[Polkadot Vault](https://signer.parity.io/) (Formerly Parity Signer) is a cold storage solution that allows you to turn your iOS or Android device into a dedicated hardware wallet for Polkadot, Kusama, and other Substrate-based chains. Your keys are kept secure (i.e. offline) at all times, and transactions are signed in an air-gapped way via QR codes. 

{% hint style="info" %}
The device on which you install Nova Spektr has to have a **camera** so that it can scan QR codes. This can be a laptop camera or an external webcam.
{% endhint %}

{% hint style="warning" %}
It is important to note that the device which has Polkadot Vault installed on it should be:

1. **Factory Reset to remove any previous data**
2. **Disconnected from the internet**
3. **Set to airplane mode**

If you turn off airplane mode, connect to the internet, or plug in your Polkadot Vault device to a computer that has internet access after setting up your Polkadot Vault you will need to repeat the process of installing and setting up Polkadot Vault.
