Concealer is a Mac program designed to help you store your credit card info, email account credentials or personal notes into a single place. The application enables you to organized the stored items into categories, brings you a comprehensive help manual and video tutorials, and allows you to export credentials and credit card data to your local directories.
You have access to 2 default entries, one for a credit card and another for storing private documents. The utility lets you store as many items as you like and export them if you want to share them with other people.
In addition, the application provides you with a password generator which might come in handy when creating new email accounts.
However, Concealer is quite limited. Unlike other apps that were developed for the same reason - store private data in one place, this utility lacks an option to sync stored info and supports only one format when exporting items to your local folders (TXT). Also, I didn't like the appearance of the interface.
Furthermore, other apps of its kind offer you quick and simple ways to log in to your accounts by using the stored information. Concealer lacks this feature.
In conclusion, you can find better solutions for storing your private data on your Mac.
