Also experiencing this issue, I thought the idea of the key store was it persisted?

Bump is this possible? On IOS it persists using the Keychain.

shouldnt. the fact that keychain is accessible later is more of a bug than a feature, in all honesty. it sort of creates a way to sort of track users, something that is against privacy and blablabla. on android, it saves a file within the data of the app bundle - once the app is removed, said file is removed along. i'm pretty sure you cant save elsewhere unless it's a rooted device (or you install some 3rd party sorta thing, like a custom keyboard or something).
