Great product, enjoying since 3 years now

Pati Rimo

I've used it since Password Retriever days and it's become possibly my most durable application that I absolutely could not live without. I find it gives me the kind of flexibility I like to organize different things as needed rather than trying to squeeze my needs into a programmer's parameters. Maybe not the prettiest but it does what it's designed to do and does it well.

Derek Meade

I create and store all user name and password combos for everything I access on the internet through use of this software, even for smart phone apps. I was recently tempted to switch to "One Password", but didn't see much difference, and didn't want to spend the extra time trying to export all of my data. One of the early versions of Data Guardian had a "clickable" button to allow the activation of the chosen URL. That feature was discontinued along the way, and I still miss it. I'd like to have such a feature made available again. I'll give a "5" rating if that is reinstated.

Andrew Foster

Totally customizable to your needs. I've needed a program like this for a while but could never find exactly what I needed. Data Guardian ended up being the end of the road for me, and I absolutely recommend it to anyone out there who is still searching.

Susan McAllister

Excellent product. My only reason for not giving 5 stars is the frequent need to update the software. Perhaps this is a strength for this type of product but it seems like a new version is available almost weekly. Also the need to save changes or new entries when closing an entry and closing the application is a minor irritation -- automatic saves would be convenient.

DataGuardian has helped me to keep my passwords for some years and ~i couldn't do without it. I wish a full version was also available for the iPhone

J Goodall

I have used Data Guardian (through at least one name change) for more than 10 years on Mac, PC and, more recently, iOS. I have used other personal database programs which I have often seen come and go. Data Guardian always works on both platforms and has been keeping track of contacts and other information faithfully and reliably for all this time. It is one program I use many times each week and have been doing so for all these many years. What other program can I say that about? Not too many come to mind.

Sam Asher

I use this product since the beginning I like it nothing else :)

Tim Hollister

Excellent product. Syncs to all my devices.
