%strong.question How does local encryption work?
%p.answer Users who opt into using local encryption can add an additional layer of security over their notes. These notes will be encrypted locally on your machine before being sent over the wire. This means that when Neeto receives your notes, we have no idea what the contents are. And if a government ever forces us to give up your data, we couldn't decrypt it for them even if we wanted to.
%p This encryption is based on your password, which is also never sent over the air. The strength of this encryption is directly tied to the strength of your password.
