The U.S. Department of Defense has disabled advertising tracking on service members' phones and computers, a move designed to reduce the risk of location data being exposed through commercial apps and data brokers.
According to a letter shared with Senator Ron Wyden, the Army, Air Force, Navy, Marine Corps, and Special Operations Command have all switched off ad tracking on government-issued devices.
The change covers iPhones, Android devices, and Windows computers used across the military network. By turning off the advertising ID, the devices become harder to identify through app-based location signals that can be combined and sold in the broader data market.
The measure follows growing attention to how commercially available location data can reveal sensitive movement patterns. Wyden said the step is a positive one, while noting that personal devices brought onto military bases may still create exposure points.
The Air Force said it updated its settings in July, while other branches had already put similar protections in place earlier this year. The broader shift reflects how digital privacy tools are becoming part of modern security planning.
As data protection and operational security continue to converge, this approach may shape a more privacy-aware future for both public institutions and everyday technology use.
