NoteBerg

NoteBerg is a privacy-first note-taking app for handwriting, rich text,
and PDF annotation - with optional Nextcloud sync.

no cloud of our own.

OPEN SOURCE
NoteBerg is fully open source (MIT license). You can review the source
code on GitHub: https://github.com/thomasleuthold/NoteBerg

NoteBerg is currently in beta and has not undergone a formal security
audit - please avoid storing highly sensitive data. Feedback and bug
reports are welcome via GitHub Issues.

Note: automatic handwriting recognition currently requires a local
Windows recognition service and is not available on Android; handwriting,
drawing, rich text, PDF annotation and sync all work fully on Android.
