AlephNote 
An extensible, lightweight desktop note client for multiple backends
(Download)
(Wiki/Manual)
AlephNote is a lightweight note taking desktop app usable with multiple backends:
Standard Note
With the StandardNotePlugin your notes get synced with a Standard File server. Your notes are locally encrypted and cannot be read from anyone but you
Simplenote
With the SimpleNotePlugin you can sync your notes with the free SimpleNote online service
Nextcloud/owncloud notes
The NextcloudPlugin syncs your notes with the notes app running on you own private nextcloud/owncloud instance
Local
You can also simply not use a remote backend and either use the HeadlessPlugin (don't sync the notes anywhere) or the FilesystemPlugin (sync the notes with another folder).
Installation
Simply download the latest release and extract it where you want (all settings etc are portable). By default the program automatically searches for new versions and downloads them. If there is demand for an installer I could make one, but personally I like portable programs more.
Attention
Sometimes Windows marks the zip-file as untrusted because you downloaded it from the web, and after extraction all .exe and .dll files will be blocked. To prevent this please right-click on the zip file, go to the file properties and click there "Unblock". Then extract the archive.
If you do the extraction first you have to do the unblocking on every single dll and exe file (see also here for a better explanation wiht images)
Contribution
Contributions are always welcome, either with additional plugins for other backends or improvements to the core app.
Also anyone with an ounce of design talent: Feel free to improve the website...
Also there are probably a ton of spelling errors, any native english-speaker can probably fix a lot of smaller errors.
