+## Security
+
+Project contains basic code for auth token management. It stores sensitive information with [react-native-encrypted-storage](https://github.com/emeraldsanto/react-native-encrypted-storage#readme) library. Although it has been listed in [react-native's official docs](https://reactnative.dev/docs/security#:~:text=react%2Dnative%2Dencrypted%2Dstorage%20%2D%20uses%20Keychain%20on%20iOS%20and%20EncryptedSharedPreferences%20on%20Android.), it's a community-maintained package. **Use at your own risk** or replace it with your own implementation.

+App uses preconfigured auth token management. It stores sensitive information via [react-native-encrypted-storage](https://github.com/emeraldsanto/react-native-encrypted-storage#readme) library.

 ## Environments
 
 There are three different environments preconfigured with [react-native-config](https://github.com/luggit/react-native-config). Use `.env.[development|staging|production]` files to place things like `API_URL`s etc.
