Trustful is a private photo vault app that lets you secure your photos and videos locally and in iCloud.
Every photo and video is encrypted locally and in iCloud using the secret key and master password, which only you know in this entire world. Your photos and videos always exist in an encrypted form. They are decrypted live only when you open and unlock the app. As soon as the app goes to background or is closed, no data can be accessed locally since everything is always in encrypted form.
