Why Your Privacy Settings Matter

Every app you install, every account you create, and every search you make generates data. Much of this data is collected, stored, and used — often in ways you haven't explicitly agreed to. The good news: you have more control than you might think. Most platforms offer privacy settings, but they bury them several menus deep and set defaults that favor data collection over user privacy.

This guide walks you through the most impactful privacy changes you can make, organized by platform and device type.

Start With Your Smartphone

On iPhone (iOS)

  1. Go to Settings → Privacy & Security to see a full breakdown of which apps have access to your location, microphone, camera, contacts, and more.
  2. Set Location Services for most apps to "While Using" rather than "Always." Only navigation apps typically need always-on location.
  3. Enable App Tracking Transparency — go to Settings → Privacy & Security → Tracking and turn off "Allow Apps to Request to Track."
  4. Check Settings → Privacy & Security → Analytics & Improvements and disable sharing diagnostic data with Apple and app developers.

On Android

  1. Go to Settings → Privacy → Permission Manager to review and revoke unnecessary app permissions.
  2. Under Settings → Location, set apps to "Only while in use" and disable "Improve Location Accuracy" if you're concerned about Google Wi-Fi scanning.
  3. In Settings → Privacy → Ads, opt out of personalized advertising and reset your advertising ID regularly.
  4. Review which apps have access to your microphone and camera — revoke permissions for any app that doesn't clearly need them.

Lock Down Your Web Browser

Your browser is one of the biggest privacy leaks. Here's how to tighten it up:

  • Switch to a privacy-respecting browser — Firefox and Brave offer strong privacy protections by default. Chrome requires more manual configuration.
  • Use a privacy-focused search engine — DuckDuckGo and Brave Search don't build a profile of your searches.
  • Enable "Do Not Track" — While not universally respected, it's worth enabling in your browser settings.
  • Install uBlock Origin — This free, open-source extension blocks ads and trackers effectively across most sites.
  • Clear cookies regularly — Or use browser containers (Firefox offers this natively) to isolate different websites from each other.
  • Disable third-party cookies — In Chrome, go to Settings → Privacy and Security → Cookies. In Firefox, Enhanced Tracking Protection handles this automatically.

Review Your Google Account Settings

Google collects extensive data across its services. Visit myaccount.google.com and review:

  • Data & Privacy → History Settings — Pause Web & App Activity, YouTube History, and Location History if you don't need personalized recommendations.
  • Data & Privacy → Ad Settings — Turn off "My Ad Center" personalization.
  • Security → Third-party apps with account access — Revoke access for any app you no longer use or don't recognize.

Social Media Privacy Essentials

Social platforms are designed to collect and share data. Take these steps on any platform you use:

  1. Set your profile to private or friends-only visibility where possible.
  2. Disable data sharing with third-party partners — usually buried in "Ads" or "Data" settings sections.
  3. Remove your phone number if it's not needed for account recovery — it's often used for ad targeting.
  4. Review and revoke connected apps — any third-party app you connected to your social account years ago may still have access to your data.
  5. Opt out of face recognition features where available.

The Bigger Picture

No privacy measure makes you completely invisible online — that's not the realistic goal. The goal is to meaningfully reduce the amount of data collected about you, limit how it's used for targeting, and ensure that data you share is shared intentionally rather than by default. Even making five or six changes from this guide will meaningfully improve your privacy posture compared to out-of-the-box settings.

Revisit these settings periodically — platforms update their terms and introduce new data collection features regularly.
