The latest version for Mac (Password 7), which supports local vaults, is available for purchase as an individual license (even for new users), here:

For a limited time, the full price of $64 is discounted $15, making a license cost $49. This license is good for any number of Macs owned. I just bought it - no subscription needed. This is also not an upgrade price - it is a full license for a new user (or existing user). This info was tucked away in this blog -

One note - if you are running Mojave (10.14 - any Beta version), the Touch ID isn't working. Otherwise it works fine, and of course works fine with 10.13.
