Preferences: Privacy

Me → Preferences → Privacy has two smaller tabs: General and Discord.

General

Clear History	Clears your search and teleport history, web browser data and the texture cache.
Show my profile info in Search results	Lets people find your profile in Search. Needs you to be logged in.
Only friends and groups know I'm online	Hides your online status from everyone else.

Look At

"Look At" is where each avatar's camera is pointed. Viewers can show it as crosshairs.

Option	What it does
Show others Look At targets	Shows crosshairs where other people are looking. Name Style chooses whether, and how, their names are shown on the crosshairs.
Show a line from the Look At beacon to its owner	Draws a line from each crosshair to the avatar, so you can tell whose it is.
Don't show me my Look At target	Hides your own crosshair.
Don't send my Look At target to others	Stops sharing where your camera is pointed.
Limit Look At Distance	Your eyes and head still move, but beyond Max Distance your Look At points at nothing in particular.

Discord

Shows on your Discord profile that you're in Second Life, with as much detail as you choose. Off until you turn it on. See Discord status for every option and the privacy rules.
