I want to store sensitive data locally in a React Native app.
Is the data only available to the app that wrote it?
I've faced the same problem on a project I was working on, we were using a custom wrapper for AsyncStorage, stored some amount of data and then we tried to retrieve the same data... and it was so easy.
We get over that problem by using Realm with the encryption option and it was a easier, faster and better solution than AsyncStorage.
