Mobile Privacy (iOS & Android Permission Audits)

Hardening Your Smartphone

Smartphones carry our most personal information: GPS history, photos, banking apps, and contacts.

App Permission Audits

Regularly review permissions under Settings:

  • Location: Set to "While Using App" or "Never". Disable "Precise Location" for apps like weather or calculators that only need city-level location.
  • Microphone & Camera: Only grant access to communication or recording apps.
  • Background App Refresh: Turn off for non-essential apps to save battery and stop background telemetry tracking.

iOS App Tracking Transparency

On iPhone, go to Settings > Privacy & Security > Tracking and disable "Allow Apps to Request to Track". This blocks cross-app advertising SDK trackers.

Android Privacy Tips

  • Use Private DNS setting with a provider like dns.adguard-dns.com to block in-app ads system-wide.
  • Review and remove unused app authorizations.
