Ascendo DataVault has only one plan type for each operating system, including Windows, Mac, Android, iOS, and BlackBerry. It charges a single flat fee for the service, which I appreciate, as subscription models can add up quickly.
Also, if you use the service for more than one year, it is probably the most economical on the market other than the always free versions of other free password managers. You can test drive the service by installing the latest version of the software for free from Ascendo’s website. But you can only run it for 30 days without registering, and to register you need to purchase.
