As Cleo doesn't store your banking data at any point, it's impossible for your data to be compromised through the app. 

To protect other personal info, like your phone number and email, Cleo uses world-class security practises to ensure the app is as safe and secure as can be.

Security audits and tests are performed regularly to challenge protocols and ensure there are no vulnerabilities in the security setup.

In short, could your bank details be stolen from Cleo? No.
