From the developer:
Annals is an application built to protect your journals. Each shelf's master key is encrypted with a derived key from its password, which in turn encrypts each item's unique key. Annals is designed to be simple to use, and for those who work better with other fonts, sizes, and colors, the entry format is fully customizable. Annals can store its data in iCloud, using CloudKit.
You may want to check out more Mac applications, such as PitStop Extreme, 3dissue or FileOpenInstaller, which might be similar to Annals.
