Your photo, name and About

Open Settings → Profile to change what others see.

• Photo — upload one, take a new one, or build an avatar. Who can see it is a privacy setting.
• Name — how you appear to people who haven't saved your number.
• About — a short line under your name. You can set one that expires by itself after a chosen time.
• Username — an optional handle people can find you by without knowing your number.

Your phone number is never shown on your profile, and you decide who can see the rest.
