@Tom Wrigglesworth, Thanks for posting in Q&A. Based on my researching, the translate app is not included in Intune protected app list.

If we configure "Send Org data to other apps" as managed app, the data transfer will be blocked. we can create exceptions to the Intune App Protection Policy (APP) data transfer policy. You can check the documentation provided by the developer of the app to find information about supported URL protocols and add it to transfer exceptions by URL protocol. If the document can't be found, you can contact the app developer to get the information.
