Keeping your online profiles private helps protect you from burglars, stalkers, and fraud. Start by reviewing each service and its controls so you know what others can see. Remember: “private” usually limits people, not the company behind a platform.
Use strong, unique passwords and enable two-factor authentication on every account. Audit any connected apps that access your information. Small changes can cut exposure quickly—set posts to friends-only, hide your page from search, and trim what shows on your profile card.
This short guide shows where to find the key controls and how to reduce data sharing across platforms. We’ll flag defaults that favor sharing and explain why that matters for your security and identity protection. Make a few high-impact updates now and set a reminder to revisit changes every six to twelve months.
Key Takeaways
- Review each platform’s controls and update them now.
- “Private” often blocks people but not companies—plan accordingly.
- Enable two-factor authentication and use unique passwords.
- Limit profile info, posts, and app access to reduce risks.
- Revisit controls every 6–12 months to stay protected.
What “privacy” really means on today’s social media platforms
A private profile usually stops other people, not the platform, from seeing your activity. That distinction matters when you think about what companies collect and how they use it.
Private to people vs. visible to advertisers: Controls you toggle mostly limit who can view posts and profile details. The platform still gathers browsing, watch, and interaction history for features and ads.
Defaults often favor personalization. Google, Facebook, and similar platforms enable broad data use for ads unless you opt out. Microsoft collects Windows and Skype profile data, and Apple offers an opt-out for ad personalization.
The U.S. landscape is a patchwork. Laws vary and protections are limited, so expect to take action yourself. Use built-in checkups and look for terms like “visibility,” “discoverability,” or “audience” when you review controls.
Tip: Turn off off-platform tracking and limit location signals in both app and OS controls to cut unnecessary data flow and reduce risks to your account and information.
Start here: Review your current social media privacy settings
Log in to every profile and run that service’s quick checkup to reveal audience and data defaults. This gives a fast snapshot of who sees posts, what profile information is public, and whether ad controls are active.
Use built-in checkup tools where available. On Facebook, run Privacy Checkup to confirm who can view posts, tags, and whether your email or phone is discoverable. On Google, use its Privacy Checkup to pause ad personalization and clear Search, YouTube watch, and Location History.
Also visit the National Cybersecurity Alliance list to jump straight to the right pages for major sites. Review app permissions on your phone and revoke unneeded access like precise location or microphone.
Keep a simple checklist of accounts and the key changes you made. Then set a recurring calendar reminder every six to twelve months to recheck. As you go, sign out unknown sessions or devices to protect account access and keep your security tight.
Control who can see your posts, profile, and how others find you
Take control of who sees your updates and whether your account appears in searches. Start by setting a default audience so new posts don’t go public by accident. Choose friends-only or a tight custom list and check this after any major app update.
Limit indexing so posts and your profile won’t show up in web search or be found by email or phone lookup. That reduces unsolicited contact and makes it harder for people you don’t know to see posts.
Tune profile fields like employer, city, and connections. Hide details that reveal routines or workplaces to reduce the risk of targeted approaches. Periodically review who can see your connections and remove people you don’t recognize.
Manage friends, custom lists, and request options
Use lists or custom audiences to share sensitive updates with only a small group. Tighten tag and mention controls so you must approve content before it appears on your timeline. Limit who can send requests—friends-of-friends reduces spam.
Quick actions: set defaults to friends-only, audit profile fields, remove unknown contacts, and review who can tag you. These moves cut exposure while keeping your account usable.
Lock down third-party app access and connected services
Connected apps often request broad access; take a minute to pare permissions back to the minimum. This reduces unwanted sharing of your data and limits how much information an app can pull from each account.
Audit app permissions and revoke what you don’t use
Check and remove unused integrations
Open each platform’s “Apps and Websites” or “Connected apps” page. Remove any tool, game, or login you no longer use. Many contests and quizzes keep access long after the giveaway ends.
Reduce data sharing across sites and services
Trim scopes and block unnecessary access
Inspect remaining integrations and downgrade scopes so third parties only get what they need. Avoid using logins that link accounts; create separate credentials when possible.
Also revisit mobile and browser permissions. Turn off camera, microphone, contacts, and precise location unless an app explicitly needs them. Be cautious with links to prevent phishing.
Document what you revoked and set a semiannual reminder to repeat the cleanup. Small, regular audits give strong identity protection and keep your accounts safer over time.
Social media privacy settings by platform: quick how-to steps
Quick platform checklists help you lock down profiles and cut unwanted discovery.
Facebook & Instagram
Run Privacy Checkup and set your default audience to Friends. Turn on tag review and limit who can look you up by email or phone.
On Instagram, consider a Private account and disable Similar Account Suggestions. Control Story sharing and who can message you.
Google & YouTube
Use Google’s Privacy Checkup to turn off Ad Personalization. Pause Search, YouTube watch, and Location History, and audit Google Photos sharing links.
Revoke third-party app access from your Google account to stop unnecessary data sharing.
Microsoft & Apple
Visit the Windows privacy dashboard and reduce diagnostic data. Check Skype visibility and app permissions for camera and mic.
On Apple devices, review iCloud Photo sharing, Find My recipients, and opt out of personalized ads.
Twitter/X, TikTok, LinkedIn & Snapchat
Limit off-platform tracking, control who can send DMs, and protect posts if you want followers-only. Adjust duet, comment, and tag controls on short-video platforms.
On LinkedIn, hide profile details used for ad targeting and limit who can message you. For Snapchat, set Snap Map to Ghost Mode and confirm friend-only access.
Location and geotagging: stop oversharing where you are
Stop sharing exact whereabouts by disabling geotags and location history on your devices. Platforms often use location for ads and suggestions, so turning this off lowers tracking and reduces risks to your identity and home security.
Disable geolocation in apps and at the device level
On your phone, open privacy controls and turn off precise location per app. Choose “While Using” or “Never” unless navigation is essential.
Remove location from past and future posts
Edit old posts to remove geotags or use bulk delete tools when available. Pause Location History on Google and delete past entries to scrub traces of frequent places.
Avoid real-time posting and check features like Snap Map; set Ghost Mode or share only with a trusted circle. Also strip embedded photo metadata before reuploading if you want tighter control over your profile and account data.
Quick tip: Reassess location controls when traveling—public signals about absence can raise theft risks and harm your security.
Strengthen account security to protect your privacy
Make each account harder to breach: choose a strong password and add an extra verification layer. Use unique passwords for every profile so one leak won’t unlock dozens of accounts.
Turn on two-factor authentication with an authenticator app or a hardware key whenever possible. Avoid SMS 2FA when you can to reduce SIM-swap risks.
Recognize phishing and suspicious messages
Be wary of urgent messages that ask for codes, passwords, or direct you to login pages. Phishing often arrives via direct messages or email and can look like it comes from friends.
Navigate to a site directly instead of clicking links. If a message asks for a one-time code, treat it as a red flag and confirm with the sender by a different channel.
Practical checks to keep access tight
Review recovery email addresses and phone numbers and remove old contacts. Check recent logins and active sessions on each account and sign out unknown devices.
Enable login alerts, keep apps and your operating system updated, and revisit third-party app access often. These steps close common gaps attackers use to steal identity and information.
