The Vault provides straightforward, easy to use, secure storage for all your documents and other data, such as passwords, login credentials, and any other confidential information. It can securely store any number of documents, images, screenshots, or photos, along with your confidential information. And while storage and access is simple, The Vault uses rock-solid, industry standard, 256-bit AES encryption.
Why is it better? The Vault is very simple to use, yet it employs industry-standard encryption to keep your data safe. (Some other paid apps do too, but some apps advertised as "secure" really do not, and, for example, save your data using a simple base-64 encoding: your information looks scrambled, but is as readable as plain text when you know how).
