Accruo v1.0 does not require account creation, and the app does not rely on a hosted personal account for its core projection workflow.
If you want to remove local Accruo data from your device, delete the app from iPhone storage. If you also want to stop future billing, cancel any active Accruo Pro subscription from your Apple subscription settings.
