The NSA is again telling phone owners to switch off one location setting

A phone’s location setting is convenient for maps, weather and finding a lost device, but leaving every app with continuous access creates a detailed record of movement. Updated National Security Agency guidance again recommends turning location services off when they are not needed. The agency also makes clear that this step reduces exposure rather than making a powered phone impossible to locate.

The updated advice focuses on unnecessary access

The NSA originally published its location-exposure guidance for national-security and Defense Department users, whose movements may carry unusual operational risk. The underlying privacy mechanics apply more broadly to ordinary smartphones.

The agency’s document gallery lists “Limiting Location Data Exposure” as updated in April 2026. Recommended steps include disabling location services when they are not required, restricting app permissions, turning off unused wireless radios and avoiding location details in shared photos.

The advice is risk-based. Navigation cannot work normally without location access, and emergency or device-recovery features may provide real benefits. The goal is to stop passive collection that offers little value.

GPS is only one way a phone reveals position

A mobile device communicates with cellular towers to provide service. Wi-Fi networks, Bluetooth beacons and nearby devices can also help infer location. Apps may combine those signals with account information and advertising identifiers.

NSA’s mobile-security guidance warns that no single mitigation fully prevents a phone from being located. Turning off the visible GPS permission therefore does not create a radio-silent device.

Permission choices can sharply reduce routine collection

Modern phones generally allow location access all the time, only while an app is in use, once, or never. Many apps function adequately with the “while using” option. Precise location can also be disabled when an approximate city-level position is enough.

A privacy review should start with apps granted continuous access. A flashlight, game or shopping app rarely needs an uninterrupted movement history. Maps, ride services and weather apps may need location temporarily, but permissions can still be limited to active use.

Photos and wireless signals create secondary trails

Camera apps can embed geographic coordinates in image metadata. Social platforms often remove some metadata, but copies sent directly or stored in shared albums may retain it. Disabling location tagging for photos can prevent an address or routine from traveling with the image.

CISA similarly advises people in sensitive roles to disable unnecessary location services and review privacy settings. Turning off Bluetooth and Wi-Fi when neither is needed also reduces signals available to nearby trackers.

Privacy improves through layers, not one switch

Location history stored in an online account should be reviewed separately from device permissions. Old data may remain even after future collection stops. Ad tracking, shared family-location tools and fitness apps can each maintain their own records.

Software updates matter because operating systems continually change privacy controls and fix vulnerabilities. Strong screen locks and account authentication protect stored histories if a device or account is compromised.

Shared-location features deserve a separate audit. Family safety tools, vehicle apps and wearable accounts may continue publishing position even when the phone’s general app permission is restricted. Access lists should be reviewed after a relationship changes, a device is sold or an old account is no longer used.

Emergency calling can involve location mechanisms that operate differently from ordinary app permissions. Disabling routine access should not be confused with disabling safety functions, and device-specific documentation should guide the choice. The best setting balances a person’s actual risk with services that person intends to keep.

Travel raises the stakes because location history can reveal hotel, workplace and daily routine. Downloaded maps, temporary permission changes and a dedicated travel device can reduce exposure for sensitive trips. Once travel ends, permissions should be reviewed again rather than left in the more permissive state.

The NSA’s renewed warning is useful because it avoids a false promise. Switching off unneeded location access can reduce how many companies and apps record movement. It cannot erase the basic fact that a connected phone exchanges radio signals, so meaningful privacy comes from limiting each unnecessary channel.

Application permissions are only one retention layer. A service may store past trips in a cloud account even after device access changes, while copies may remain in backups or data shared with business partners. Deleting history, changing future-collection settings and removing an application are separate actions whose effects should not be assumed to be identical.

Location sharing can also expose other people. A photograph, calendar entry or family-tracking group may reveal a household member’s routine even when that person’s own settings are restrictive. Group administrators should remove stale members, check who can invite others and avoid publishing real-time travel plans when delayed sharing serves the same purpose.

Periodic review matters because software updates and new applications can change the permission landscape. A quarterly audit of always-on access, precise location, photo metadata and shared accounts catches settings that were reasonable for a short trip or event but no longer serve a continuing need.
