Turn Personalized Ad Recommendations On or Off auf Xiaomi
Personalized ad recommendations is a system-level setting on Xiaomi phones that lets MIUI use your app activity and search behavior to choose which promotions show up in system apps and pre-installed tools.
The toggle sits under the privacy section, separate from general notification or app permission settings. It only controls relevance, not frequency: turning it off keeps the same number of banners but removes the profiling behind them.
To change it, go to Tap on Settings ➤ Tap on Passwords & security ➤ Tap on Privacy ➤ Tap on Ad services, then use the switch to Enable or disable Personalized ad recommendations.
If your goal is fewer ads overall rather than less relevant ones, this setting will not help since ad volume stays fixed. It is the right fix specifically when you want to stop Xiaomi from using your data for targeting, without changing how often ads appear.
The menu path is the same across recent MIUI releases, so you do not need to check your exact version before making the change.
