Are you the owner of a Protonet server, or were you invited onto one as a user? Then get your Protonet Messenger now and use all the important functions of our software SOUL OS, any place and any time via your smartphone. Send messages, photos, or share your location, while your data is still completely safe on your personal server. FUNCTIONS Private chat and sharing of pictures Send pictures, videos, and message remotely via your smartphone to all users on your Protonet server. Protonet SOUL OS automatically recognizes on which device you are currently active. If you are working on your laptop with SOUL OS, you will receive a message directly through the browser, if you are underway you receive a push message on your smartphone. Location sharing Share your location with specific users for as long as you wish. These selected users will receive a push notification, and via the integrated map (map from Open Street Maps), they are able to see what your exact location is and where you are moving to. AND YOUR DATA? All the data that you share via the app is secured with a strong SSL encryption, just like all the communication done through the Protonet server. Because of our custom made technology, the Protonet server can send the text output from one smartphone to another. And the best part about this is that Apple or Google do not get their hands on your data. HOW DOES IT WORK? Firstly, in order to make use of the Protonet Messenger you need a Protonet server. Either you own one or were invited onto one as a user or guest. The rest is very simple: 1. Download and install the app 2. In the app enter the name of your Protonet server eg. carla.protonet.info 3. Enter the same login data that you use when you login to your Protonet server. 4. Spread the word of our new Protonet Messenger app. Do you not have a Protonet Server yet? Take control of your data and become independent! Please keep in mind that continued use of GPS running in the background can dramatically decrease battery life.
