To stop random people from finding and adding you on Snapchat, go to Settings and tighten the privacy options that control discovery and contact. The most important changes are turning off See Me in Quick Add and setting Contact Me to My Friends.

What to change

  1. Open Snapchat and tap your profile icon, then the settings gear.
  1. Find See Me in Quick Add and turn it off so your account is less likely to show up in suggestions.
  1. Set Contact Me to My Friends so strangers can’t message you as easily.
  1. Check whether people can find you by phone number or email and turn off those discovery options if available.
  1. Block or report anyone who keeps adding or messaging you repeatedly.

What this does

These settings reduce random adds, but they may not make you completely invisible on Snapchat. Some sources note that you can’t fully prevent your username from being searched, so the goal is to make your account much harder to discover and contact.

Extra privacy moves

  • Keep your phone number and email out of public discovery if Snapchat gives you that option.
  • Use Ghost Mode for Snap Map if you also want to limit location-based visibility.
  • Remove or block unknown accounts that are already bothering you.

TL;DR: Turn off Quick Add , set Contact Me to My Friends , and disable phone/email discovery where possible.
