Frustrated with Samsung Notes locking my notes into their ecosystem, your data isn't really yours. No good alternative existed.
So I started ONF, an open vendor-neutral format for handwritten digital notes. Standard ZIP under the hood, fully open spec, designed for the long term.
Early draft + C++ reference implementation on GitHub. Looking for experienced people to help get it right:
