Control of your data
Well ok, technically the data is on my servers. However, I will NEVER abuse your data, and in most cases, it is completely inaccessible, even to me.
Security
All data is sent via encrypted TLS tunnels to my self-hosted servers. Your data is at significantly lower risk of compromise, since the big players are the ones being targeted.
Privacy
You may have nothing to hide, but big companies have no rights to your data. Using these services ensures that your data stays yours.
Functionality
Fifthdread Services should not only be more secure, but also retain key functionality you can find elsewhere- if not improve on it.
