Start with what your profile reveals
Your profile may show more than the posts you publish. Depending on the service, other people may be able to see your profile photo, bio, friends or followers, location, workplace, contact details and accounts you follow. Open your account’s privacy settings and review each item separately. Menu names vary by service, so look for options such as Profile, Audience, Visibility or Privacy.
Decide what someone needs to know before you make a detail public. A name and photo might help acquaintances recognize you, but a phone number or home location may not need to appear on your profile. Some services keep certain details, such as a display name or profile picture, visible even when an account is private. Check the explanation beside each setting rather than assuming that one “private account” switch hides everything.
Choose an audience for each post
Before publishing, look for the audience selector near the post button. Common choices include everyone, followers, friends, a smaller list or only you. Pick the smallest audience that suits the purpose of the post. A public announcement may need broad visibility; a family update probably does not. Some services remember the audience you chose last time, while others apply a default, so check it each time you share something sensitive.
Posts are not the only things with audiences. Stories, short videos, photo albums, live sessions and comments may have separate controls. A reply on a public post or in a public group may be visible more widely than a post on your own profile. If you are unsure who can see an item, pause before sharing and inspect the audience label or the group’s visibility information.
Review older posts and other people’s tags
Changing your default audience usually affects future posts, not everything you have already shared. Browse older posts, albums and profile updates, especially those containing personal details or photos of others. Many services offer an activity log or a tool for limiting the audience of past posts. Check what such a tool covers before using it: posts made in groups, shared copies and other people’s posts may need separate attention.
Tags and mentions can connect your name to material you did not publish. Look for settings that let you review tags before they appear on your profile, and consider who can see tagged posts once they are there. Removing a tag may disconnect it from your profile, but it does not necessarily remove the original post. If a friend has shared something you would rather keep private, ask them to change its audience or remove it.
Check what others can actually see
If the service has a “view as” or profile preview feature, use it to inspect what a stranger can see. You can also check your profile while signed out, although some content may be hidden behind a login screen. Review search settings, too: a service may offer a choice about whether external search engines can link to your profile. Changes to search visibility may not take effect everywhere immediately.
Make privacy reviews a habit after you add profile information, join a group or notice a change in the app’s menus. It can help to check from both the website and the mobile app, since controls may be placed differently. If you manage more than one account, confirm which one you are editing before changing settings.
Know the limits of privacy controls
Audience settings reduce visibility within a service, but they cannot guarantee that a post stays within its intended circle. Someone who can see it may take a screenshot, copy the text or describe it to someone else. Connected apps and public group activity can also expose information in ways that are easy to overlook. Before posting, consider whether you would be comfortable with the content being passed along.
Privacy also depends on keeping control of your account. Use a strong, unique password, enable two-step verification if available and review unfamiliar devices or connected apps in your security settings. If someone is bothering you, blocking or restricting them may help, but check what each option does on that service. The most useful approach is to combine careful sharing with regular checks of your settings.
