I Have Question For Samsung IME Keyboard

I am developing a service that brings user-generated data into our app.
Among these, I became interested in a service that recommends values previously entered by the user from Samsung IME.

Q. Is it possible Getting Samsung Keyboard IME Personalized Prediction Data?

Q. How to Samsung IME Store Personalized Prediction Data, is it stored on Device? or Cloud Data?

It it not possible to access personalized IME data by any third party applications. This is applicable for all keyboard apps unless they specifically provide a feature to extract user data.

Then I Have Question
How to Stored personalized IME Data?
Is it Stored Each IME In App Storage? or Cloud Saved Data?
Is there any way to receive it if the user requests his or her data?
