Wow! Probably would have done this had I known earlier, but at this point I feel like if I lock myself in to their platform they'll eventually get rid of this option completely at which point I'd have to find an alternative anyways.
don't bother. I bought the license for mobile and mac when those were the options and now regulated to paying subscription.
I don't think that's correct, they completely support standalone licenses, and you can use Dropbox for syncing across devices. I'm using 1password 6 on my Mac, and 1password 7 on windows, no problem, no subscription.
It is indeed possible to purchase standalone licenses for 1Password 7 for Mac and 1Password 7 for Windows and they can be synced using Dropbox.
