Platform-by-platform quick hits (Image credit: Getty Images) Here are the most impactful privacy switches to flip on each major platform: Facebook: Set your profile to “Friends only” for posts, limit past posts visibility, disable search engine indexing, and restrict who can look you up using your email address or phone number.

Instagram: Switch to a private account in Settings > Privacy.

This prevents strangers from seeing your posts or stories.

Disable activity status, restrict tag approvals, and turn off location sharing on posts.

Snapchat: Enable “Ghost Mode” in Snap Map settings to hide your location.

In Privacy Control, set who can contact you and view your story to “Friends Only.” Review your “Find Friends” settings regularly to control whether your account is suggested to other users.
