So:
- You're not in the U.S.?
- For some reason you think you don't have to comply with HIPAA?
- For some reason, your insurance company doesn't care if you comply or not?
- You're not a doctor - but just play one on TV?
I'll ask a doctor friend. He's always completing his notes at home. Pretty sure, though, he's using the online medical records system of his medical group.
The idea of doctors taking medical notes in some random, unencrypted, note-taking software on their notebook is scary. We need a new Dr. McCoy quote for this:
"I'm a doctor, not an IT technician! Get Spock on this HIPAA stuff!"
I remember the first patient notice I got under HIPAA. My dentist's office was burglarized, and they had to notify all of their patients of the breech, and that medical and/or financial data might have been compromised. That was several years ago, and there was still a lot of naivete and disregard/ignorance about data security in the medical industry.
Maybe you can comply by keeping your computer in a locked safe when not in use.
