Security and privacy are two of the most important issues in today's world; leaving passwords on sticky notes around your computer simply will not cut it anymore. Data Guardian is a secure database application with full Blowfish encryption — regardless of how sensitive your data is. Create multiple databases in Data Guardian for a variety of purposes such as an address book, customer database, Christmas shopping list, journal, password manager, or even notepad.

Easily create collections to store records, and even apply custom color labels and icons! Change the view options for each collection to see the information you want, and add your own custom data fields. Do not be stuck with a program which forces you to input your information into predefined fields. Enter the data you need to, not what you are forced to.

Aside from Data Guardian's easy to use Keychain integration* to autofill passwords on web sites, it also offers a variety of other tools and features to enhance each record. Dial phone numbers through your modem with a single click, create new e-mail messages, generate secure passwords (based on an algorithm of your choosing), and even synchronize two databases.

Data Guardian is the ultimate database solution, and not only if security is a priority. Allow it to become your computerized Swiss Army Knife in an age of digital chaos.

Simple & Easy to Use

I use the recent version and it does what it promises with an easy to use interface. My data is safe and I can quickly access it with a single password. I like that it locks when not used for a duration. It could have more features, though simplicity and ease of use make it nice!

DO NOT BUY THIS APP - Terrible Support from this Developer!

I have been using this for a long time, starting back when it was Password Retrever. I originally chose it, and still love it, for its simplicity. Other password apps require you to make a choice for each entry, as to whether it is a password, or credit card, or bank accoung. The simplicity of this interface is wonderful, and I appreciate that the developer has continually updated it on their website.
NOTE: I have to report that I am DONE with this application. It stopped working because the developer said my email was rejecting mail from their server??? In any case, it will no longer work. I wrote to the developer, AND I wrote to Koingo, where I bought the non App Store version. It has been SIX WEEKS and no response from either.

I have been using Data Guardian since it was Password Retriever and Love it!
It's the best thing I've found for keeping all of my passwords and software serial numbers.
You can make your own record templates easily and have all the info you need for site logins, serial numbers and many other things stored securely and ready a click away whenever you need them. You can also keep the database on Dropbox or something similar if using it on multiple computers.
