I have some data to be stored with my iOS/Android app.
The data exists as files.
Are these files visible to users?
They can just browse the file directory & copy my files to their local drives?
If I have sensitive data to be stored with my app, what would you advise? Store the data with encryption?
For iOS you should store sensitive data in keychain. Apple docs provide a detailed description regarding keychain storage. You can check the below link.
