When you search for something on your phone, your activity (searches, clicks, app usage) is tracked by advertisers and analytics systems. That data is used to build a digital profile of your interests, so similar ads or products appear in other apps or websites you use.
🧠 How it works:
1. You search for something → trackers (cookies, pixels, SDKs) collect data.
2. Ad networks link this info to your device ID (Advertising ID, IP, etc.).
3. The same or related ads then appear elsewhere (cross-app tracking).
🛡️ How to reduce tracking:
• On Android: Turn on Opt out of Ads Personalization and Reset Advertising ID.
• On iPhone: Turn off Allow Apps to Track.
• Use privacy browsers (DuckDuckGo, Firefox Focus), a VPN, and an ad blocker.
• Remove unnecessary app permissions (like location, mic).
