If the app recognizes the transactions correctly as transfers between your own accounts, they will not be taken into account for the reporting ('incoming', 'outgoing' tabs).

If you have any transfers, the app did not recognize as such, you can change their category manually to eliminate them from the reports:

• on iOS: select the transaction either from the reports or in the list of transactions > with a swipe to the right you can change the category  'transfer'
• on macOS: please select the transaction from the list of transaction - at the moment you cannot change the category from the reports directly > open the transaction details and change the category 
• on Android and Windows 11 / Amazon FireOS: select the transaction either from the reports or in the list of transactions > with a swipe to the right you can change the category
