I'm working with an app dev team who are capturing a preference flag called OptIn that is being pushing to Adobe Campaign Standard via collectPii.
The developers want to be able to retrieve this flag so they can show the current status on a preference screen in app.
I believe that they need to store locally on the device to do this. I pointed them towards using Profile to store this attribute locally and they have asked how data stored in the local Profile is kept secure?
I can't find any detail in the document? Are these data encrypted?
