I've used Evernote for many years now. From snipped recipes to very personal information and business stuff under NDA's. I always called it an extension of my brain.
I have a premium account, because I believe in paying for services I rely on and I trusted that this gives companies to have a viable business mode, the whole "If you're not paying for it, you're not the customer." concept.
This news got me worried, not only about future situations but also the current. I kinda expected that my data would have been encrypted, but learned here that's not the case. I must say that's shocking. I'm always very restrained with using services and putting content online, but Evernote was always a no-brainer for me. I hope Evernote hears the concerns and acts on it, because they'll lose paying users.
€60 for a service as Evernote that has my privacy and security as primary focus, not a problem. €60 for a service as Evernote that I only (can) use for snipped recipes and grocery list, no way.
