Ask HN: How do you sync and share data from your smartphone?

I have many use-cases where I sync data like text, messages, photos, contacts or notes from my smartphone to my computer.

- What are your setups / solutions to sync your data to your own PC? - What are your solution to send it to a friends oc or smartphone?

I am not using google photos or other google cloud services, hence I may have more use cases than others.

What I do: - Syncthing ( https://github.com/syncthing/syncthing ) for particular folders and photos to my laptop / PC. - Share via http ( https://github.com/marcosdiez/shareviahttp ) to share files from my smartphone to someone else in the network. - etesync ( https://github.com/etesync/server ) for private calendars and contacts

I do not have a process for sharing to someone directly through the internet. Firefox send comes to.my mind here?!
