Sync Notes from Mac and iOS devices without iCloud
NOTE: i assume in my answer that you just don't want the Apple iCloud servers
you need an other email account to do this

you add one more email account (any but not iCloud)
and then you activate at this email account the section NOTES
the notes are created in an imap folder named notes
do it on both: iPhone and Mac
then you move all notes on Mac to the other account
then you can switch off the NOTES with the iCloud account

iPhone (iOS10):
Settings -&gt; Notes -&gt; Accounts -&gt; (some account) -&gt; notes -&gt; switch: on/off
OSX 10.11.6
Settings -&gt; Internet Accounts -&gt; (some account) -&gt; notes -&gt; checkbox: on/off
