Frequently Asked Questions

How do I start using ChatFOSS?

Register as a parent by clicking the sign up button. You will receive an email with instructions how to set up all your family. The whole process only takes a couple of minutes.

How do I add friends on ChatFOSS?

You are automatically friends with everyone in your family - that is all users set up by the same person.

To add more friends on ChatFOSS simply swap ChatFOSS usernames and add your friend to your list of friends. As soon as they do the same, you can start chatting.

Neither you nor your friend will be able to see that the other wants to chat with you until you have both added each other. This prevents others from guessing your username and bothering you.

If your friend does not have a ChatFOSS ID or you don't know it, you can also invite them via their email address or phone number.

You can remove a friend at any time.

Can I set up a group chat?

Yes, in ChatFOSS groups are called circles. A circle is created automatically for your family.

To set up a new circle, you simply create a list of friends to invite. You will only join a circle if you accept the invitation. This prevents anyone from adding you to groups you do not want to be part of.

How is ChatFOSS different from other communication apps?

ChatFOSS is designed to be private.

In ChatFOSS no-one can search for you or contact you other than those you have requested and accepted as friends. Only if both users have independently requested to be friends with each other can they connect. You remain in control of whom you communicate with.

ChatFOSS parents receive a notification each time one of their family members adds a new friend.

ChatFOSS carries no advertisements or in-app purchases. We will never sell your data. Your information is yours only.

Who is behind ChatFOSS?

StayPrivate is the company behind ChatFOSS. StayPrivate makes no money from ChatFOSS and they do not access or sell your data. ChatFOSS is entirely financed by StayPrivate's Corporate Social Resposibility programme.

Why should we use ChatFOSS?

ChatFOSS uses start-of-the-art security technology so that when you share pictures, videos and messages with your family and friends you can be confident that they will not be accessed by anyone else.

ChatFOSS is not just designed to be secure, it is designed to be private. Every conversation is conducted within a private channel, and every conversation stays in that channel.
