575 Using Privacy Settings More Effectively | Finding Privacy Settings on Your Accounts, and Checking Privacy Settings on Shared Devices


Privacy settings control who can see information and how an account or service may use certain data. The available choices differ between platforms and can change after updates, so privacy is not a one-time setup. Profiles, posts, location sharing, activity history, advertising preferences, and shared-device access may all have separate controls.
This section focuses on finding and reviewing those settings in a practical way. It covers audience choices, location and activity sharing, advertising and tracking options, changes after software updates, and extra care when an account is used on a shared device.

575.1 Finding Privacy Settings on Your Accounts

Privacy settings are often spread across several parts of an account rather than placed on one page. Look for sections named privacy, security, permissions, data, activity, advertising, profile visibility, or connected services. Mobile apps may also have device-level settings that override or limit what the account itself can do.
Start with the controls that affect the widest exposure: public profile information, post audiences, location sharing, contact discovery, search visibility, and connected apps. Read short explanations before changing unfamiliar options, because a setting may affect a useful feature as well as privacy. If the service has a privacy check-up tool, it can provide a useful overview, but it should not replace checking the settings most relevant to your own use. Prioritizing settings that expose information widely or control sensitive data makes a short review more useful than changing every option at once, especially after account or app updates.

575.2 Choosing Who Can See Your Profile and Posts

Profile and post visibility determine whether information is open to everyone, limited to contacts, shared with a selected group, or kept private. A public account can be useful for a business, creator, or professional role, while a personal account may need a narrower audience. Older posts can also have different settings from new ones, so changing the default may not change everything already published.
Choose an audience that fits the purpose of the account and the type of information being shared. Review details such as phone number, birthday, workplace, family links, and friend lists separately when the platform allows it. Test the public view of the profile if that option exists. Remember that anyone who can see a post may be able to copy or forward it, so audience controls reduce reach but do not make sensitive content impossible to spread. Profile visibility should reflect the real purpose of the account rather than the platform's most open default.

575.3 Controlling Location and Activity Sharing

Location and activity sharing can make services more useful, but they can also reveal routines, travel, exercise, visits, or periods when a home may be empty. Some sharing is direct, such as a live-location link, while other sharing comes from tagged photos, public check-ins, map history, fitness records, or background app access.
Check both the account setting and the device permission because they may control different parts of the feature. Turn off continuous sharing when a temporary need has ended, and review who still has access to live or historical location. For activity histories, consider whether storage is necessary and how long records are kept. Removing visible location from a post may not remove location data already saved elsewhere, so prevention is usually easier than later cleanup. Repeated location records can reveal patterns that a single check-in would not, so old sharing links and stored histories deserve periodic review over time.

575.4 Managing Advertising and Tracking Choices

Advertising settings can influence how activity is used to choose or measure ads. Depending on the service, controls may cover personalized advertising, activity from partner sites, data from connected accounts, or the use of advertising identifiers on a device. Turning personalization off may change the type of advertising shown without removing advertising or all data collection.
Read what each control actually changes instead of assuming one switch stops every form of tracking. Browser privacy tools, cookie choices, device settings, and account preferences can work together, but each has limits. If an option is unclear, choose the more private setting first and see whether the service still meets your needs. Revisit the choice after major updates because labels, defaults, and available controls can change. Advertising choices often reduce personalization rather than eliminate all collection, so labels should be read carefully. Advertising controls should be read for what they actually change.

575.5 Reviewing Privacy Settings After Updates

Software and service updates sometimes introduce new features, reorganize menus, or change default choices. A privacy setting that once matched your preference may move or a new feature may begin sharing data in a way you have not considered. Updates are also important for security, so the solution is not to avoid them; it is to review important privacy choices afterward when changes are substantial.
Pay attention to notices about new sharing, personalization, location, artificial-intelligence features, connected services, or revised account controls. Check the settings that matter most to you rather than reading every menu item. If a platform announces a material privacy change, review its explanation and available choices. Keeping a short list of your highest-priority settings makes this review faster and less dependent on remembering every previous option. Important settings are worth rechecking after major changes rather than assuming old choices carried over exactly.

575.6 Checking Privacy Settings on Shared Devices

A shared device can expose an account even when its online privacy settings are strong. Browsers may save sign-ins, apps may remain open, notifications can appear on a locked screen, and downloaded files may be visible to the next person. Family, school, workplace, library, or public devices therefore need different habits from a personal device.
Use a separate user profile or private session when available, avoid saving passwords, and sign out fully when finished. Check downloads, recent files, and notification settings if sensitive information was viewed. Do not assume closing the browser ends every session. On a device shared regularly with trusted people, separate accounts can reduce accidental access without treating the other users as threats. The goal is to match privacy controls to shared access. Shared access changes the privacy situation even when the online account itself has strong settings. Shared devices require privacy habits beyond ordinary account settings.
