By default, WhatsApp will automatically set your privacy settings to allow any WhatsApp user to view your profile photo, status, last seen and Read Receipts.
To change these settings, simply open WhatsApp and tap More > settings > account > privacy.
You can set the following options separately for last seen, profile photo and/or status.
Your profile photo, status and/or last seen will be available to all WhatsApp users.
Your profile photo, status and/or last seen will be available to your contacts from your address book only.
Your profile photo, status and/or last seen will not be available to anyone.
Blocked contacts will not see your status, last seen, typing..., online and will not see any updates to your profile photo. Learn how to block a contact here.
