A review from a customer Ripped Off in the Koingo-Macupdate dispute.

No idea who is right or wrong, but the customer was the jetsam.

My legal Macupdate purchases of Koingo software were unilaterally, without notice, cancelled by Koingo.

Main thing I found interesting in my relegation to rubbish in their dispute, was trying and failing to make contact with Josh Hoggan of Koingo, who publicised the Macupdate CEO's email address, but appeared to hide his own.


Zero stars for Koingo.

This is the most used product I "lease" from Koingo but I will be quite happy to drop it along with the others I subscribe to if someone at Koingo doesn't grow up. I sent a message to Koingo on their web site this morning which reads as follows:
Good Morning from New Zealand, This is not really about Data Guardian but about my relationship with Koingo. I feel it my duty as a free citizen to point out that your current licensing policies are an anathma with a great many subscribers, planet wise. Coupled with this, your ongoing mountain out of a molehill spat with macupdate is doing no one any good, least of all your companies revenues and koingo licence holders attitude towards this petty little squabble which has grown to enormous proportions. If you do not read the comments on macupdate.com in regard to your leased products and your policies, then I suggest you do so with urgency. It would appear that someone in your company is harbouring a "pride comes before a fall" attitude and I would say that if common sense does not prevail, then the future of your ompany is bleak. I use three products from your companys lease stable, with Data Guardian being the most used but there are alternatives and I would not cry too much if you went under. 2014 is a new year and when the holidays are over, surely its time for someone at Koingo to grow up, bite the bullet and mend some bridges before its too late. Anyone can be stupid, it takes a man with guts and fortitude to evamuate his failures and apologise and then move on. For goodness sake, grow up you guys!

Regardless of your feelings about Koingo, I don't see any justification for posting your letter here, especially since there's no reply to accompany it.
Since you posted it as a review, it would have been better to post an actual review of the product instead of your tirade to the company.

"I feel it my duty as a free citizen to point out that your current licensing policies are an anathma with a great many subscribers."

Your "duty" as a "free citizen?" ROFLMAO!
It may be your RIGHT, but it certainly isn't your DUTY.

BTW, it's spelled anathema,

I have 31 licenses for Koingo software, I have been a customer for many years, since 2008. I personally have never had a problem with them, I have had cause to contact support and always had feed back, and a resolution to the problem.

I find it sad that MacUpdate, and Koingo, both don't just agree to disagree.

This past week end Macupdate was also not so innocent selling it's own software, and not bothering to answer all the questions, that were asked. As a sub note the software is ropy at best, it tells me updates for software like camera bag area available, but they are not?? But for $10

Come on guys, we all make mistakes, but it's how we deal with the mistakes that make up better people. I thought the whole mac community spirit was better that calling each other names, or posting silly comments at the top of pages, which is no better than a form or censorship, once you go down that road, it could lead any where…

Shake hands and go your separate ways, thats what was always told to me.

I wasnt so upset that the licenses were pulled, although it was incentive enough to never purchase a koingo app in the future. But what truly took the cake was the spam email I just received from koingo, where they are practically begging for contact information of 5 friends so they can go and spam them as well. Not gonna happen, and I hope you enjoy your rating.

Koingo is not a trustable company. Why not informed the bundle customers about the ilegal licenses sold by MU, immediately, not after months.

We were hoping there was another option, and we didn't have to revoke licenses. Unfortunately, there wasn't.


I recommend reading the full correspondence behind the ordeal. I feel it was a tough situation for both sides:



Thanks for the link to the correspondence log. I read the whole thing. It ought to be obvious to anyone with a objective frame of mind that Koingo Software is run by an arrogant person who has absolutely no sense of integrity. He shifts his positions to suit himself; he takes no responsibility for his unethical, unprofessional behavior; and he is completely unreasonable in his demands for a settlement to a whole slew of problems which he created from the outset by his incompetence.

This individual is way too greedy and way too controlling to ever merit any sympathy or support from me. He's maliciously trying to make MacUpdate the fall guy for his many personal flaws and inadequacies. How pathetic can one get?

His latest ploy, issued today, offers a "free" license to customers whom he originally infuriated by unilaterally voiding the version 3 licenses which they had legit steely obtained in a free bundle arrangement negotiated by MacUpdate on behalf of their customers and to allow Koingo to expand its customer base.

What kind of a businessman "gives back" something which customers had originally purchased, declares it an act of generosity on his part, and libels the distributor who set up the whole deal in clearly written terms from the outset? I'll tell you. A greedy developer who wants to sucker you in to his coral, so that he can pester you from now until forever with email campaigns offering you all sorts of upgrade "deals" for a hefty price. That's the kind of manipulation which is going on here.

You'd have to be a fool to get suckered into his spider web of deceit. I'm no fool. I'm done with Koingo Software. If you've got any sense at all, you will be done with him, too. Let him self destruct, if he's so inclined. He deserves his own demise.

I have been using Data Guardian since version 1.2.8 (december 2007) and upgraded to 2.x and 3.x. I like the features to keep all my private information at a safe place with a strong encryption.
The flexibility to create new custom fields is great and I can use the same encrypted database file without any limitation at Windows with DG for Windows.
I wish that Koingo Software will soon improve the iOS version and develop an Android version…
Keep up the good work!

So Koingo decided to take my license away and is spamming reviews with the same message over and over. My license was coupled to my e-mail address and Koingo has been using that e-mail address to mail me their ad-mails since I bought the Macupdate package. Koingo obviously wanted my e-mail address as part of their participation in the package deal. If you did not have the right to have my e-mail address it makes your e-mail messages nothing more than spam. I usually buy updates to software I like but I don't trust your company anymore.

I have been using since version 2, upgraded to version 3, and have nothing against it, since it does what it is supposed to do, and does it well. I did not notice any speed hit (Macbook Air with SSD drive), using it with Mountain Lion. In an age of NSA folks feeling they have the right to unlawfully snoop anyone in the world, the stronger the encryption I can have available to me, the better! Don't know of any similar apps with such strong 448-bit Blowfish encryption.

The developer's repeated response sounds like a broken record. If MU was not authorized to give away copies of Data Guardian, how did the end users end up with working registration? I'm pretty sure MU didn't crack Koingo's system and issue a bunch of rogue licenses, so that leaves the only possibility being that Koingo issued licenses and then had a change of heart.

Initially I had a license for DG 3, then it became a license for DG 2. But DG 2 won't open a DG 3 database, so that left users unable to access their databases.

Just because the developer keeps repeating the same mantra over and over doesn't make it true; and given my previous bad experience with Koingo with regard to upgrading Alarm Clock Pro this doesn't surprise me in the least.

So now my rating. Features I cannot access? ½ star. Having to juggle trial versions of v2 and v3 give an ease of use rating of ½ star. Not being able to use DG 3 earns a value rating of, you guessed it, ½ star. And stability, well if I can't use it then that's pretty unstable so DG 3 goes 4 for 4 with ½ star ratings. And for the overall rating I'm going to quote Jayne from Firefly/Serenity:

…nothin into nothin, carry the nothin…

To access Data Guardian 3 files with the Data Guardian 2 app, all you have to do is manually change the file's extension from dg3 to dg2. That is all you need to do.
In regards to your comments about Koingo, I can't disagree with you. Even if one would accept Koingo's side of the story regarding their dispute with MacUpdate, the best spin I can give Koingo is that they suffer from the worst customer relations that I have ever encountered from any company.


Thanks for the tip @Arcarnat, that will save me and probably others a lot of headache. :-)

Despite of what is going on between MacUpdate and Koingo this still is a decent piece of software. It does not offer the sophisticated system integration of 1Password (which has a distant price tag...) but is much easier to use than TrueCrypt. And it uses a decent encryption method, not the dated 256-bit AES some competitors have.
Although I am perfectly able to ssl-encrypt my files with homebrewn shell scripts, I prefer Data Guardian for its ease of use.
