A secure, open-source replacement for Skype is currently in the works.
Tox is a voice-over internet protocol (VoIP) client that also aims to deliver video-calling capabilities, according to its website. Other features include encrypted instant messaging and file sharing.
Tox also promises to be privacy focused.
"With the rise of widespread government monitoring programs, Tox is an easy to use application that allows you to connect with friends and loved ones without anyone else listening in," read a paragraph on the site.
""Tox is built with the idea that you can keep up with friends and family without having your privacy violated. While other big-name services require you to pay to unlock features, Tox is free in both price, and in liberty. That is, you're free to do whatever you wish with Tox."
The private focus comes after a series of NSA spying leaks, including allegations that Skype developers left a 'backdoor' for spying on user conversations.
The program isn't available to download just yet, but users are encouraged to help build it.
