Take Back Control

You cannot erase tracking, but you can shrink it a lot:

• Audit app permissions — revoke camera, mic, and location from apps that do not need them. A flashlight app wanting your contacts is harvesting, not helping.
• Use a privacy browser — Firefox blocks known trackers by default, and Brave also blocks ads and fingerprinting scripts.
• Turn off ad tracking — on iPhone: Settings, Privacy, Tracking. On Android: delete your advertising ID under Privacy, Ads.
