For the first time I've recently been seriously considering going paperless at home.

However, every great solution involves uploading my scans to online services.

This is something I'm not comfortable doing with my sensitive data (i.e. tax records).

Has anyone found or developed tools that can be run locally to organize my files? Something like evernote? I'd like to just scan and shred, and not have to fuss too much with naming files, manually organizing files, etc. A good pdf search interface is a must.
