The MoneySavingExpert app

There are two main types of data used in the MSE app.

First, like most apps, it uses cookies to keep you logged in and to provide MSE with helpful information on how the app is being used. You can opt in and out of cookie categories within the app settings.

The second is your spending data. We use Open Banking technology that allows MSE to take a top-level look at your spending and payments, to help give you more relevant information about what you can do to save. We've made sure we've taken the security of this data very, very seriously.

• The app (and MSE) does not store any bank account or credit card details or login information.
• It can't access your bank account or move money (not that we'd want to, anyway).
• Nobody at MSE or MoneySupermarket Group (which we're a part of) can see your banking or spending data.
• We use 256-bit encryption to connect with your bank or credit card provider – we know that sounds techy but it's important.
• When you've connected your bank account or credit card account, we'll ask you to set an additional PIN or enable 'biometric login', so that there's an extra layer of security.

You can also stop the app having access to your banking data if you change your mind, plus you can de-link your account from the app via your bank (through its mobile banking app or online banking). Plus, the app can still be used for free without registering, so if you want to, you can use it and provide absolutely no personal data (but you will get a less tailored experience).

Your data-sharing preferences can always be updated in the app settings. You can read more in MSE's Privacy Policy.
