How we use behavioural information to help better protect you

Behavioural information refers to data that measures patterns in how an individual moves, behaves, or interacts with their device. It can include factors such as how a device is held or moved, how a person types or taps on the screen, and other routine interaction patterns. This information reflects behaviour rather than personal content, and is often used to help verify identity or detect unusual activity.

CommBank is collecting behavioural information about the way you interact with your devices while using the CommBank app, NetBank and CommBiz. This includes information about how you interact with your devices such as typing speed, keystroke patterns and mouse movement to help identify potential fraud. 

CommBank collects behavioural information to help detect suspicious cyber activity and financial crime to combat fraud and scams, such as identity theft. 

Behavioural information allows CommBank to understand how a customer typically uses their device. When activity falls outside these patterns, it may signal a customer’s account has been compromised or unauthorised device use. 

The way that you interact with our digital platforms is used to help identify if a third party is in control of your banking. All behavioural information we collect is held by our trusted third party in a de-identified form to help maintain your privacy. 

Your behavioural information will only be collected when you are using the CommBank app, NetBank and CommBiz. 

If you don’t consent to this information being collected, you won’t be able to use these platforms. We can support you to remove your NetBank ID if required.  

If you don’t want CommBank to collect this information for you or your child (who is under 14 years old), you will need to go to a CommBank branch and request the removal of their NetBank ID or de-register devices that have the CommBank app.
