Think about what you share before pressing Publish. Your public profile and the audience selected for a post are different privacy choices. A setting that controls who can contact you does not necessarily change who can see work already published.
Review public information
Check your name, username, photograph, bio and any country information displayed on your profile. Share only details you want other people to see. A declared profile country is information you choose; it is not proof of your physical location.
Use the controls available
Open Settings and Privacy and review Privacy Settings. Read each control's description before changing it. Use blocking guidance for unwanted contact, and check the audience shown in the creation screen for the post or Status you are making.
Account access matters too
Protect your confirmed email and review the Security Center. Connected Apps helps you examine services you authorised. Removing future access does not automatically erase information already received by another service.
Requests and retention
Read data downloads and account deletion before submitting a request. A queued request is not an immediate download or completed deletion. Applicable privacy information explains retention and available rights; use the Privacy Policy entry in settings to read it.
Ask a specific question
For an unclear setting or request, use in-app support. Explain which app, screen and audience you mean without sending private credentials or another person's personal information.
