π« Common Mistakes in Understanding Online Tracking
- π΅οΈ Mistake 1: Thinking all cookies are bad. πͺ Not all cookies are harmful. First-party cookies can improve your browsing experience by remembering your login information or shopping cart items.
- π Mistake 2: Believing incognito mode makes you invisible. π Incognito mode prevents your browser from saving your history, cookies, and login data, but it doesn't hide your IP address or prevent websites from tracking you through other means.
- π§ Mistake 3: Assuming email is private. π§ Email providers often scan your emails to personalize ads. Using end-to-end encryption can help protect your email privacy.
- π± Mistake 4: Forgetting about app tracking. π± Mobile apps can track your location, usage habits, and other personal information. Review app permissions and privacy settings regularly.
- π Mistake 5: Confusing tracking with hacking. π¨ Tracking is about collecting data, while hacking involves unauthorized access to your accounts or systems. They are different, although tracking data can sometimes be used in hacking attempts.
- π Mistake 6: Ignoring privacy settings. βοΈ Many websites and apps allow you to control the amount of tracking they do. Take the time to review and adjust your privacy settings.
- π« Mistake 7: Thinking a VPN stops all tracking. πΊοΈ A VPN hides your IP address, but websites can still track you through cookies, fingerprinting, and other methods.
