Thank you for your inquiry regarding the integration of your data with the Loyverse app, Acc18. 

I can provide general advice on best practices for data security. However, for specific questions  regarding the security protocol, data handling, and privacy policies of the third party app, I recommend reaching out directly to the official Loyverse Customer Service website, they are equipped to address any concerns related to security measures.

Once the safety has been confirmed by them, as long as this third party app supports QuickBooks, you can proceed with the integration.

Please leave us a response if you have questions or other concerns regarding the integration with QuickBooks. We're always here to advice and assist you.
