How do I use #syncthing:

On my mobile phone:

- Synchronize photos/videos and notes to my server for archival and my desktop computer

On my desktop computer:

- Synchronize scanned and stored documents to my server to process them with paperless-ngx
- Synchronize notes to the phone

It is good not having to think, it just syncs. Hosting it on my own makes me responsible and is work, but I do not have to use services of big companies.
