Many people worry about hackers, but not as many consider the apps they use daily. Some of the most popular apps are also the biggest privacy offenders.

• TikTok collects a lot of data, such as device details, your location, how you use the app, and your interactions.
• Facebook tracks what you do not only on its own apps but also on many other websites, using advertising and analytics tools.
• Instagram gathers information like your behavior, search history, location, contacts, and how you interact with content to personalize ads and suggestions.
• Google Chrome saves your browsing history, searches, cookies, and other data, especially if you are signed into your Google account.
• Google Maps tracks your exact location, travel routes, places you visit, and your searches unless you turn off these settings.
• Amazon collects information about your shopping habits, browsing history, Alexa voice recordings, and purchases to improve its targeting and recommendations.
• Snapchat gathers your location, contacts, device details, and how you use the app, especially if you use features like Snap Map.
• X (formerly Twitter) collects data about how you engage with content, your device, your browsing activity, and your interactions with ads.
• LinkedIn tracks your professional activity, what you search for, whose profiles you view, and how you engage to improve its recommendations and ads.
• Temu has been criticized for the amount of device and user data it requests and collects, raising privacy concerns in several countries.

So, should you delete these apps?

• Not always.
• But it is important to understand the tradeoff.
• If a service is free, your data is often what pays for it.
• Most of the time, privacy is not lost all at once.
• Instead, it is usually given up bit by bit—one permission, one click, and one accepted policy at a time.

Which of these apps do you trust the least with your personal data?
