<ahref="https://syncthing.net">Syncthing</a> provides a similar capability to proprietary systems such as Dropbox, and also is well suited for use with low power single board computers. You can have one or more directories which are synchronized across your various laptops/desktops/devices, and this makes it hard for you to ever lose important files. The manner in which the synchronization is done is pretty secure, such that it would be difficult for passive adversaries (mass surveillance, "<i>men in the middle</i>", etc) to know what files you're sharing. Of course, you don't necessarily need to be running a server in order to use Syncthing, but if you do have a server which is always running then there's always at least one place to synchronize your files to or from.

<h3id="org9394f3b">Direct Messages (DMs) and privacy</h3>
One important point about GNU Social is that although direct messages (DMs) are treated as being private their security is quite poor. If you want real communications privacy then use other systems such as XMPP+OMEMO/OTR, Tox or email with GPG. GNU Social is primarily about <i>fully public communications</i>.
If you have the GNU Social microblogging system installed then it's also possible to share things or services between groups or with particular users. This can be useful for sharing items within a family, club or in a local sharing economy. Sharing things freely, without money, reveals the social basis at the root of all economics which money normally conceals or obscures.

Both Hubzilla and GNU Social try to obtain certificates automatically at the time of installation via Let's Encrypt. This will likely mean that in order for this to work you'll need to have obtained at least one "official" domain via a domain selling service, since Let's Encrypt mostly doesn't seem to work with free subdomains from sites such as freeDNS.
IRC is useful for multi-user chat. The classic use case is for software development where many engineers might need to coordinate their activities, but it's also useful for meetings, parties and general socialising.

Tor Messenger is a messaging client which supports XMPP, and its onion routing enables you to protect the metadata of chat interactions to some extent by making it difficult for an adversary to know which server is talking to which. You can download Tor Messenger from <ahref="https://torproject.org">torproject.org</a> and the setup is pretty simple.
Tox is an encrypted peer-to-peer messaging system and so should work without Freedombone. It uses a system of nodes which act as a sort of directory service allowing users to find and connect to each other. The Tox node ID on the Freedombone can be found within the README within your home directory. If you have other users connect to your node then you will be able to continue chatting even when no other nodes are available.
In addition to voice it is also possible to do text chat via mumble. The security of this is pretty good provided that you do it via Plumble and Orbot on mobile, but compared to other options such as XMPP/Conversations or Tox the security is not as good, since the mumble server currently doesn't support forward secrecy.
Freedombone also supports SIP phones The username and domain is the same as for your email address, and the SIP password and extension number will appear within the README file in your home directory. Various SIP client options are available, such as CSipSimple on Android and Jitsi on desktop or laptop machines. Ideally use clients which support ZRTP, which will provide the best level of security.
<ahref="https://jitsi.org/Documentation/ZrtpFAQ">ZRTP</a> appears to be the current best standard to end-to-end encrypted voice calls, combining good security with simplicity of use. When the initial cryptographic negotiation between phones is done at the start of a call a short authentication string (SAS) is calculated and displayed at both ends. To check that there isn't anyone intercepting the call and acting as a <i>man in the middle</i> - as <ahref="https://en.wikipedia.org/wiki/Stingray_phone_tracker">stingray type devices</a> try to do - the short authentication string can be read out and verbally confirmed between the callers. If it's the same then you can be pretty confident that the call is secure.
The way that RSS reading is set up on Freedombone gives you strong reading privacy. Not only is there onion routing between you and the server but also between the server and the source of the RSS feed. The only down side is that many RSS feeds are still http only, and so could be vulnerable to injection attacks, but it's expected that more of this will go to https in the foreseeable future due to a combination of growing recognition of security issues and systems like Let's Encrypt which make obtaining certificates much easier.
