While it might seem a bit ironic that the safest way to store your personal data is sometimes to upload it to a website, the truth of the matter is you never know what's going to happen to all of that valuable information stored on your computer in the event of a disaster. If your house burned down, what would happen to your family photos, financial records, and license keys for software you've paid for?

While we've looked at a variety of ways to store files and documents offsite, KeyFiler does one thing and does it well: lets you store license keys an registration information for web sites and programs. You can create an account for free and start storing your data within moments. Your information is encrypted and stored on Keyfiler's servers. If you're really paranoid, you can choose the high security option when you signup, and if you lose or forget your password, KeyFiler will refuse to let you reset it.

Once you've entered your data, you can export it as a CSV file, or print a report showing all of your license information for software or websites fitting certain criteria.

The service is free to use, but has a clever advertising-based business model. As the About KeyFiler page points out, registered users are almost certainly people who have paid for software in the past. So odds are they'd be willing to pay for software in the future. That's a pretty compelling reason for advertisers to sign on.
