How we use your information

Mobile apps

We have two mobile apps:

  • The Premium Bonds prize checker app, for checking if you’ve won any prizes
  • The NS&I app, for viewing your account balances and transaction history

We use cookies and similar technologies to help us understand how you use our apps, spot bugs and make improvements.

They can last for different lengths of time depending on the job they do. Some last for the length of your online session and are removed automatically from your device when you leave the app, and others last for a set period.

You can manage which types of data, cookies and similar technologies you agree to us collecting in our apps.

Currently there are two versions of the NS&I app – a new version 5.0.0 and older versions 4.0.10 and below. Version 5.0.0 collects different types of data, cookies and similar technologies to previous versions. We will only collect this information if you have updated to the latest version of the app and given us your consent.
