Is google sheet safe to use

[Odiez]

I want to know, if I make a app, and there is personal data in my sheet in google sheet, how safe is it, so if someone copy my app, can they see my data

If the app needs authentication and the user is set as just an app user, he/she is not able to copy the app or able to see the data if the data is filtered with the security filter. If you give the access to copy the app, then yes the copy will have your data as well.
