Been using it pretty happily for like 15 years, but now the need for cross-device access and synchronization has finally become apparent. What I'm looking for is:

1. All or most of Tranglos KeyNote functionality, including tree structure, rich text formatting, text search. Explicit tagging would be nice too.

2. Synchronization between Windows 7 SP1 and Android.

3. Data should be stored locally on my devices and recoverable without access to my note-taking software account. Why? Because I had my Microsoft account temporarily blocked twice already without any reason, warning or explanation. Google is known to do that too, only per-document rather than per-account. I'm not going to trust my vital data to any buggy third party security scripts anymore, thanks.

I'm looking at Evernote right now... Seems to be close to what I need, but the option to recover data without access to my account is not clearly described. Any better ideas?

Please note that while I'm all about opensource, in this particular case opensource alternatives are welcome only if they've been around for long enough, in production stage and with no major issues. The data in question is just too important to me to use it for beta testing.
