I'm about to start working on a expense tracker app for mobile and I would like to use React Native with Expo (pretty new to mobile techs). Maybe I will share it with some friends or other people and the question that cames up is where to store their data (in this case is sensitive as they will register their money's movement).

What I mean is, I could use any cloud DB (Mongo, Firestore, etc) but I will have access to everything they register there and I wouldn't like that, just for security and their privacy sake.

So, is there a way to store their data or everything they register locally in their phones? So the app can only access to the data that is stored there and I can't see it. Or any other possibility?

I found the AsyncStorage API but I don't know if this is the correct approach for what I'm looking for. I didn't code anything yet as I don't know which would be the right path.

I had a similar case and i went for realm.js .

You can use Secure Store since you're using expo.

expo-secure-store provides a way to encrypt and securely store key–value pairs locally on the device. Each Expo project has a separate storage system and has no access to the storage of other Expo projects. See https://docs.expo.dev/versions/latest/sdk/securestore/
