You can think of cookies like stickers. Every time you visit a site, that site puts a sticker on you so they can keep track of how many times you’ve visited, how long you’ve spent there, and what you’ve done. That lets the site show you things which are relevant to you, based on information you’ve entered and stuff you’ve looked at. The length of time stored depends on the cookie, but this is generally between a few minutes and up to two years.
Cookies never store any of your banking details.
We use a couple of different kinds of cookies:
We use session cookies to improve our site and give you a better experience. Session cookies let us see where you spend your time, and work out which bits are most (and least) effective. We use persistent cookies to recognise you when you come back to our site. When we spot that it’s you, we’re able to show you the things that we think you like.
Exactly how to do it depends on your browser or phone settings. Try looking in your ‘Help’ section, or searching for ‘How to block cookies’.
If you turn cookies off, you might still see ads for Monzo in other places. But they’ll be general, and not based on your specific information.
