Yes, it is safe! FloatMe uses the same systems and security as many banks and other finance products you know, to securely connect your bank account to the app.
The security and authentication system is called Plaid. It is also used by 12,000+ banking institutions around the world. And yes, that probably means your bank too!
We need your bank information in order to verify your income, enable us to send Floats to your account, and take repayment for the Floats on their due date.
