How to Protect Smartphone Privacy and Stop Unwanted Ads with These Simple Settings

In today’s digital world, smartphone privacy and unwanted ads are two of the biggest concerns for users of all ages. Whether you’re a student, professional, or tech-savvy grandparent, knowing how to control what your phone shares and who sees it is more important than ever. Fortunately, by adjusting a few simple settings, you can significantly boost your privacy and reduce those pesky ads that seem to follow you everywhere.

Smartphones are incredibly powerful tools, but they also collect a lot of personal data. From your location to your browsing habits, this information is often used to deliver targeted advertisements. While some users appreciate personalized content, many others find it invasive. Thankfully, you can take control without needing to be a tech expert.

Protect Smartphone Privacy and Stop Unwanted Ads

Smartphone privacy is no longer a luxury — it’s a necessity. By following these simple yet effective steps, you can protect your personal data, reduce unwanted ads, and enjoy a safer digital experience. Whether you’re a casual user, parent, or cybersecurity professional, taking control of your phone’s settings is a powerful step toward digital autonomy. These privacy tips not only shield you from advertisers but also enhance device performance, battery life, and peace of mind. Start with the basics today and build your privacy shield one step at a time.

Why Smartphone Privacy Matters

Every time you install a new app or browse a website, data about your actions may be collected. This data is often sold to advertisers who then create detailed profiles about you. These profiles can include your:

• Location
• Purchase history
• Browsing habits
• Device type and IP address
• App usage behavior

This can lead to targeted ads, price discrimination, or even scams. For professionals and parents alike, protecting this data is critical.

Real-World Example

Imagine you search for sneakers on your browser, and later, every app shows you shoe ads. That’s targeted advertising in action — and it relies on your data being shared across services.

Additionally, companies may use your smartphone’s sensors (gyroscope, accelerometer, etc.) to infer behaviors. This underscores the importance of not just permissions, but ongoing app monitoring.

Data privacy also impacts your professional life. Business travelers, remote workers, and freelancers often use their phones for sensitive tasks, such as accessing client files or financial apps. A compromised smartphone can lead to data leaks, identity theft, and loss of business reputation.

Stop Unwanted Ads and Boost Privacy

Step 1: Disable Personalized Ads

On Android:

1. Go to Settings > Privacy > Ads.
2. Tap Delete advertising ID.
3. Enable Opt out of Ads Personalisation.

On iPhone:

1. Go to Settings > Privacy & Security > Tracking.
2. Turn off Allow Apps to Request to Track.
3. Go to Apple Advertising, turn off Personalized Ads.

These steps reduce the personalized data advertisers use to target you.

Step 2: Revoke Unnecessary Permissions

Apps often ask for more access than they need. Review and restrict permissions:

Android:

• Settings > Privacy > Permission Manager.
• Revoke access to Location, Camera, Microphone, Contacts, and Files for apps that don’t require them.

iOS:

• Settings > Privacy.
• Review each category and toggle permissions off as needed.

Permissions like background location and microphone access can lead to continuous tracking even when the app is not in use.

Step 3: Block Pop-ups and Notifications

These can be annoying and sometimes dangerous. Disable pop-ups:

• In Chrome: Settings > Site Settings > Pop-ups and redirects > Block
• Turn off Push Notifications for suspicious apps via your phone’s notification settings.
• Safari users can go to Settings > Safari > Block Pop-ups.

Unwanted notifications often lead to scam links or deceptive promotions. Limiting these improves focus and security.

Step 4: Use Private DNS (Android Only)

Private DNS helps block ads at the system level:

1. Go to Settings > Network & Internet > Private DNS.
2. Select Private DNS provider hostname.
3. Enter dns.adguard.com or dns.familyshield.opendns.com.

Private DNS not only blocks ads but also improves browsing speed and encrypts your DNS queries, preventing ISPs from seeing your online activities.

Step 5: Install Ad Blockers and Private Browsers

Some great options include:

• AdGuard – Provides system-wide ad blocking and tracking protection.
• Blokada – Open-source, non-root ad blocker for Android.
• DuckDuckGo Browser – Automatically blocks trackers and enforces HTTPS.
• Brave Browser – Offers built-in ad blocking, anti-tracking, and privacy-friendly search.

Private browsers prevent websites from building behavioral profiles, helping maintain anonymity.

Step 6: Use a VPN for Extra Protection

A VPN (Virtual Private Network) hides your IP and encrypts all traffic. Choose a trusted provider like:

• ProtonVPN
• NordVPN
• Mullvad VPN – Known for strict no-logs policies

VPNs are especially useful on public Wi-Fi networks in airports, cafes, or hotels. They ensure your online activities cannot be intercepted by third parties.

Step 7: Enable OS-Level Security Settings

Android:

• Use Google Play Protect to scan apps.
• Enable Advanced Protection under Security settings.
• Turn on Find My Device and Screen Lock.

iPhone:

• Use Lockdown Mode for sensitive environments (Settings > Privacy & Security).
• Enable Silence Unknown Callers.
• Use App Privacy Report to track app behavior.
• Ensure Face ID/Touch ID and passcode are enabled.

These features reduce risks of phishing, surveillance, and unauthorized access.

Step 8: Use Encrypted Messaging and Backup Safely

• Switch to encrypted messaging apps like Signal, Telegram, or WhatsApp for secure communication.
• Backup your data using encrypted cloud storage or encrypted offline methods. Avoid public or unknown services.

Additional Tips

• Avoid suspicious apps: Only download from official app stores like Google Play or Apple App Store.
• Keep your OS and apps updated: Updates often include important security patches.
• Use two-factor authentication (2FA): Adds an extra layer of account protection.
• Clear browsing data regularly: Helps prevent long-term tracking.
• Limit location sharing: Use “Allow only while using the app” wherever possible.
• Set app usage limits: Some apps continuously collect data even when idle. Set screen time limits.
• Turn off Bluetooth and Wi-Fi when not in use: Prevents passive tracking and unauthorized access.
