* data ownership - including in the event the startup is bought
* data access revocation - I want to be able to revoke access to my data in a meaningful way
* business plan - I want to be the customer not the product for something like this
* portability - I don't want to feel that I'm stuck using any one solution for my life.
I really don't know if such a service can be made economically viable given such a set of requirements.
Sandstorm pretty much meets those requirements:
* Your data is exportable
* They focus on security and have a non-privacy-invading business plan
* You can decide exactly who to share data with, and revoke it.
It's like a private hosted cloud - you have to pay for it yourself (once it's out of beta), but you could host it yourself, and it's open source.
I'd love to do something with a fully encrypted system, but the usability / recovery trade offs just didn't seem worth it when designing the site.
I work and am pursuing my master's, so I haven't had a ton of time to build an app for it.
Or the data is warranted by a judge in a civil or family case?
