Despite popular belief, iPhone isn't using your microphone to spy on you, but Big Tech's data collection remains complex. The constant feeling of being followed by targeted ads stems from behavioral tracking, not device eavesdropping. Performing a privacy audit helps limit what companies collect about your habits and interests across apps and websites.

Start with Siri by disabling "Hey Siri" if unused in Settings > Apple Intelligence & Siri > Talk to Siri. Revoke unnecessary permissions for microphone, camera, and location services under Privacy & Security. Toggle off Analytics & Improvements to prevent sharing usage data with developers. These steps significantly reduce your digital footprint within the Apple ecosystem.

App tracking across websites and other apps poses the greatest privacy risk. Disable this feature in Settings > Privacy & Security > Tracking by toggling off Allow Apps to Request to Track. Review and revoke permissions for individual apps that don't genuinely need your data. Regular privacy audits maintain control over your information in an increasingly data-driven world.
