1. Don’t overshare: Even with AI tools like ChatGPT

AI chatbots like ChatGPT are useful, but they’re not private journals. The platform owners may have privacy policies and use the latest security measures, but that doesn’t mean you should let your guard down. When using these tools, refrain from sharing any personal information, such as your name, address, birthdate, passwords, financial details or sensitive conversations. Remember that AI systems store and process your inputs, and despite security promises, data breaches can occur.

SCAMMERS CAN EXPLOIT YOUR DATA FROM JUST 1 CHATGPT SEARCH

Tip: Treat all online forms of AI interaction like public forums. Keep your examples generic and use caution with anything that could identify you.

If you’re going to input your personal information while using these AI tools, ensure there is an option to prevent them from sharing it. On ChatGPT, for instance, do the following:

• Go to Settings.
• Click Data controls.
• Tap Improve the model for everyone.

• Toggle off Improve the model for everyone.
• Click Done.

Why it matters: AI tools may seem personal, but they’re not secure vaults. Guarding what you share helps prevent misuse, identity theft or data leaks from breaches.

2. Use alias email addresses

Your email is often the key to your online identity and a common target for spam. By creating disposable email aliases that forward messages to your main inbox, you can keep your real address hidden from websites and services. These unique aliases act as shields, so if one starts getting spammed or is involved in a data breach, you can simply deactivate it without affecting your main email account.

My top recommendation to avoid being inundated with spam emails is to use an alias email address. An alias email address is an additional email address that can be used to receive emails in the same mailbox as the primary email address. It acts as a forwarding address, directing emails to the primary email address.

In addition to creating throwaway email accounts for online sign-ups and other circumstances where you would not want to disclose your primary email address, alias email addresses are helpful for handling and organizing incoming communications. 

Sometimes, it’s best to create various email aliases so that you don’t have to worry about getting tons of spam mail or having your information taken in a data breach. An alias email address is a great way for you to stop receiving constant spam mail by simply deleting the email alias address. See my review of the best secure and private email services here.

Why it matters: You stay anonymous, avoid data leaks and never have to change your main email address again.

3. Take advantage of Facebook’s privacy checkup

Meta frequently updates its privacy settings, so it’s best to check regularly to see how you can improve your privacy. Use Facebook’s Privacy Checkup tool to review and adjust crucial settings, including post visibility, app permissions, search visibility and friend-request settings. This comprehensive tool helps ensure your profile remains as private as you want it to be. You can find the tool by following these steps:

• Log in to your Facebook app on your phone.
• Then click the menu icon in the bottom right.
• Tap Settings.
• Click Privacy Checkup.

Once you open the Privacy Checkup, you’ll be guided through several key areas to customize your privacy preferences and better control your information.

• Who can see what you share: Adjust who can view your posts, photos and profile details to limit access to only people you trust.
• How people can find you on Facebook: Manage who can send you friend requests, look you up using your email or phone number, and decide whether your profile appears in search engines.
• Your data settings on Facebook: Review which apps and websites have access to your Facebook data and remove any you no longer use or trust.
• How to keep your account secure: Set up two-factor authentication, update your password and monitor login alerts to protect your account from unauthorized access.
• Your ad preferences on Facebook: Control how Facebook uses your activity to show you personalized ads and opt out of categories that feel too intrusive.

Quick tip: Set a reminder to run a privacy checkup every few months, especially after major Facebook updates. This way, you’ll always be in control of your information.

Why it matters: Social media platforms thrive on your personal data. Adjusting your settings regularly puts you back in control of what others and Facebook can see and use.

HOW TO PROTECT YOUR ONLINE PRIVACY AND SECURITY ON YOUR NEXT CRUISE VACATION

4. Scrub yourself off the internet automatically

Your name, phone number and home address may already be listed on people-search sites like Spokeo, Whitepages and BeenVerified. These data brokers collect and sell your personal information without you even knowing it. Fortunately, personal data removal services are available to protect your privacy. They automatically send legal removal requests to hundreds of data brokers. They also go above and beyond by continuously monitoring them in case these third parties happen to get your information again.

While no service can guarantee the complete removal of your data from the internet, a data removal service is really a smart choice. They aren’t cheap and neither is your privacy. These services do all the work for you by actively monitoring and systematically erasing your personal information from hundreds of websites. It’s what gives me peace of mind and has proven to be the most effective way to erase your personal data from the internet. By limiting the information available, you reduce the risk of scammers cross-referencing data from breaches with information they might find on the dark web, making it harder for them to target you. Check out my top picks for data removal services here.

Why it matters: The less personal information available about you online, the harder it is for scammers and identity thieves to target you and the more peace of mind you’ll have. 

10 SIMPLE STEPS TO IMPROVE YOUR SMARTPHONE’S SECURITY AND PRIVACY

5. Use a privacy-focused messaging app

If you’re still using standard texting apps or platforms like Facebook Messenger, it’s time to upgrade to a more secure option. Apps like Signal and Session offer end-to-end encryption, no ads and no metadata tracking, meaning they can’t see who you’re talking to or what you’re saying. Both apps support disappearing messages, giving you more control over how long your conversations stick around.

Why it matters: Your messages stay private and can’t be accessed by hackers, advertisers or the app developers themselves.

6. Stop Google from tracking your every move

Google collects a massive amount of data from your searches, YouTube views, Gmail activity and location history, all of which fuels targeted advertising. You can stop much of this tracking by turning off Ad Personalization and deleting your activity history. Here’s what to do:

• Go to Google’s My Ad Center.
• Find the Ad Personalization section.
• Toggle the switch to turn off ad personalization. This stops Google from using your activity to tailor ads.

Manage activity history

• In My Ad Center or via your Google Account, go to Data & Privacy.
• Under History Settings, review and pause or delete: Web & App Activity, YouTube History and Location History (if applicable).

Delete existing activity data

• Select Manage all Web & App Activity, Manage all YouTube History, etc.
• Delete past activity by choosing a time range (e.g., “All time”) and confirming deletion for each category.

Opt out of third-party ad personalization

• Scroll to Ad settings and look for third-party ad personalization options.
• Opt out of partner sites’ ad personalization if available.
• If you have multiple Google accounts, repeat these steps for each account.

Why it matters: Cutting down on ad tracking reduces how much of your online behavior is used to build a profile on you, often without your knowledge.

7. Turn off location tracking on your smartphone

Apps don’t need to know your every move. Disabling or limiting location tracking is one of the simplest ways to protect your physical privacy. Here’s what to do:

iPhone:

• Go to Settings.
• Tap Privacy & Security.
• Click Location Services.
• Scroll down and tap the app you want to manage.
• Choose your preferred setting: Never to block location access completely; Ask Next Time Or When I Share to allow location only with your permission; While Using the App to allow location only when the app is open.

For apps like Maps, toggle Precise Location off to prevent pinpoint tracking.

To disable location tracking entirely, toggle Location Services off at the top of the Location Services page (this will stop all apps from using your location).

Android:

Settings may vary depending on your Android phone’s manufacturer.

• Go to Settings.
• Tap Location.
• Tap App permissions or App location permissions.
• You will see a list of apps grouped by their location access: Allowed all the time; Allowed only while in use; Ask every time; Not allowed.
• Tap any app to change its location permission. Choose from: Allow all the time; Allow only while using the app; Ask every time; Don’t allow.

For apps that have location access, you can also turn Precise location on or off if you want to limit accuracy. Repeat for each app you want to manage.

Tip: If you want to stop all apps from accessing your location, you can turn off Location at the top of the Location settings page.

Why it matters: Prevents apps, advertisers and even your OS from building a detailed map of your daily routines.

8. Change the default admin password on your router

Most routers ship with default admin usernames and passwords like “admin” or “1234,” and these are publicly available online. Hackers know this and often scan networks looking for unprotected routers. Here’s what to do:

• Log in to your router’s settings via its IP address (often 192.168.1.1 or 192.168.0.1).
• Change the admin username and password to something strong and unique.
• Consider using a password manager to generate and store complex passwords. Get more details about my best expert-reviewed password managers of 2025 here.

Why it matters: Prevents intruders from hijacking your home network and spying on your devices.

9. Enable WPA3 encryption on your Wi-Fi router

WPA3 is the newest wireless encryption protocol and offers much stronger protection than WPA2. If your router supports WPA3, enabling it is a no-brainer. How to check:

• Log into your router settings and look under Wireless Security.
• If WPA3 is available, enable it.
• If not, consider upgrading to a newer, security-focused router. Check out our top routers for best security 2025.

Why it matters: Stronger encryption means hackers can’t easily intercept or crack your Wi-Fi traffic.

10. Set up a guest network for visitors and smart devices

Your friends don’t need access to your entire home network and neither do your smart lights and doorbells. Creating a guest network adds a safety barrier between your personal devices and less trustworthy ones. Steps to take:

• Log into your router settings.
• Create a separate guest network with its own password.
• Connect smart devices, TVs and guests to this network only.
• Keep your main network just for personal computers and phones.

Why it matters: Even if a smart device gets compromised, the attacker won’t have access to your main network or sensitive devices.

11. Use a secure, private browser for sensitive browsing

Not all browsers treat your privacy equally. Switching to a browser designed for privacy like Brave, Firefox or DuckDuckGo’s browser can drastically cut down on the amount of data collected about you while you browse. Also, use incognito/private mode for sensitive searches. 

Why it matters: Reduces digital fingerprints and helps stop advertisers and data brokers from building a profile on you based on your browsing behavior.
