By default, your mobile number and email will be visible to your contacts on Qwil Messenger. However, if you prefer to keep your personal details private you can always edit your public contact details from the desktop app.
To keep your personal details private we suggest you set your public details to be an office number or general / and generic email as you deem fit.
Simply click on your avatar (top right) on desktop and go to Profile - see Edit my public contact information.
