5.2 Secret Share Storage
Secret shares are the individual secret keys each vault owner stores on their mobile device. Since these secrets should not be shared, they are stored in encrypted storage on the users device.
Only the Tholos mobile app can use the secret share. Other applications can not view, delete, or modify your secret share. Secret shares do not leave your device.
Secret shares are securely stored in Apple Keychain Services.
Secret shares are securely stored in EncryptedSharedPreferences
