Long time user of 1password; love the product, love the security of not having my passwords stored in the cloud by default and of being able to then select/manage/change whether or not I want to use cloud storage providers for data sync on my own. This is the very reason I have pushed every member of my team to use 1password in the past, as opposed to using a service like LastPass. The most secure system (that isn't turned off) is one which isn't connected to the Internet, after all.
As a security specialist with a strong background in crypto concepts (and having read your whitepapers/available materials on your site), I understand what you're going for and why your protections can be considered sufficient. That said, I am still not satisfied with my password vault being uploaded automatically to your servers. When you are compromised (it's never if, these days), someone could take the vaults they obtain and launch brute force cracking efforts on a cluster of AWS GPU instances. Thus is born a risk of possible compromise of all of my passwords. This risk simply doesn't exist if you're breached when the vault is only on my systems.
I understand from having searched through the forums to see questions like mine (will you continue to sell standalone licenses?) that you will not; this is your new business model and customers are welcome to continue using their standalone apps until they stop working, at which time you're willing to see them move to something else.
This saddens me, because your product is fantastic and I would gladly pay (as would my team/company) for perpetual licenses to new releases of your solutions on our platforms of choice such that we could continue to have local-only storage of our vaults. I guess optionally, I'd be happy to have the subscription, without the account/automated data upload. If this is truly the end of local-only vault support, then I regret to say that when the current solution stops working (hopefully not any time soon - please keep supporting it! ) that I may no longer be able to use/recommend your solution. Additionally, I'll have the first member of my team (currently undergoing a platform change) who will have to stop using it. I guess that leaves KeePass, which I'm not nearly as big a fan of for usability reasons.
So, all of the above is to say, I understand that at the moment your mind is made up, and you're doing what you're doing. I hope it works for you and wish you the best, but here's a request from a current customer to please reconsider and offer an option to use 1password without mandating/requiring automatic vault upload to your servers. In my case, target platform is Windows + iOS. Some members of my team are OS X + iOS, and I've got a couple Android users, as well.
