Most location privacy problems come from small defaults nobody questioned during development, which makes them easy to prevent. Use the reminders below the next time you build or review a feature that touches location data.

1. Ask Whether You Need Location at All

Start with the simplest question. Could a city picker, a postal code field or a manual search do the job just as well?

A weather app can ask for a city. A store finder can let users type a neighborhood. A manual option respects users who prefer to keep their location private and gives your app a fallback when permission is denied.

Reminder. Every piece of location data you never collect is data you never have to protect, store or explain.

2. Choose Approximate Location by Default

Both Android and iOS let apps request an approximate location, which places the user within a general area. Local news, regional pricing and nearby recommendations all work well at that level.

On Android, declare the coarse permission in your manifest.

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

On iOS, add a key to your Info.plist to make reduced accuracy the default.

<key>NSLocationDefaultAccuracyReduced</key>
<true/>

Save precise location for features that clearly depend on it, such as turn-by-turn navigation or a delivery driver finding a front door.

Reminder. Users accept permission requests more readily when the app asks for less.

3. Request Permission Only When It's Needed

Asking for location the moment an app opens is one of the most common mistakes. Users have no context yet, so many simply tap "Don't Allow." Wait for an action that needs location, such as tapping "Find stores near me," and ask then.

Here is a simple Android example in Kotlin that requests permission at the moment of need and offers a fallback.

val locationPermissionRequest = registerForActivityResult(
    ActivityResultContracts.RequestPermission()

) { isGranted ->
    if (isGranted) {
        showNearbyStores()

} else {
        showManualSearch()
    }
}

fun onFindNearbyClicked() {
    locationPermissionRequest.launch(
        Manifest.permission.ACCESS_COARSE_LOCATION
    )
}

On iOS, the Info.plist explanation appears inside the permission prompt, so write it in plain language.

<key>NSLocationWhenInUseUsageDescription</key>

<string>We use your approximate location to show stores near you.</string>

Then request "When In Use" access in Swift when the user triggers the feature.

import CoreLocation 
let locationManager = CLLocationManager() 
func onFindNearbyTapped() {
    locationManager.desiredAccuracy = kCLLocationAccuracyReduced
    locationManager.requestWhenInUseAuthorization()
}

Reminder. Reserve background location for features that genuinely run when the app is closed. Both app stores review those requests closely.

4. Round Coordinates Before Storing or Sending Them

Full coordinates are rarely necessary, even with precise access granted. Two decimal places narrow a location to roughly one kilometer, and three decimal places narrow it to about a hundred meters. Pick the lowest precision your feature can work with.

import kotlin.math.pow import kotlin.math.roundToLong

fun roundCoordinate(value: Double, decimals: Int = 2): Double {     val factor = 10.0.pow(decimals)     return (value * factor).roundToLong() / factor }

Apply rounding on the device, before the data reaches your servers, analytics tools or logs.

Reminder. Raw coordinates often slip into debug output and crash reports, so search those too.

5. Strip EXIF Metadata From Photos

Photos taken on phones often carry hidden EXIF metadata, including the exact GPS coordinates where each picture was taken. Profile pictures, listings and chat images can all carry that location along with them.

• Remove GPS tags from images on the device before upload.

• Strip metadata again on your servers as a second layer of protection.

• Download an uploaded image and check it with any free EXIF viewer to confirm the tags are gone.

Reminder. Most users have no idea their photos carry coordinates, so they rely on you to catch it.

6. Set Clear Retention Limits

Location data grows riskier with age. Months of history can reveal routines, relationships and habits that one data point never would.

• Delete raw location data automatically once the feature no longer needs it.

• Keep aggregated or anonymized statistics when you need trends over time.

• Document retention periods so your whole team follows the same rules.

• Make sure deletion also covers backups, analytics platforms and third-party tools.

Reminder. Old location history is a liability waiting for a breach.

7. Review What Third-Party SDKs Collect

Once a user grants location permission to your app, bundled ad, analytics and attribution SDKs can often read it too.

• Review the documentation and data practices of every SDK you add.

• Disable location collection in SDK settings wherever possible.

• Monitor network traffic during testing to see what data leaves the device.

• Remove SDKs you no longer use.

Reminder. Users hold your app responsible for everything it shares, including data collected by tools you did not write.

8. Be Transparent With Users

Tell users what location data you collect, why you need it and how long you keep it, in plain language. Make it easy to change permissions or delete location history from inside the app.

Keep app store privacy labels and data safety sections accurate, and update them whenever your location practices change.

Final Thoughts

Privacy-safe location sharing comes down to three habits. Collect less, keep it for a shorter time and be honest about it. Privacy-focused products, such as private browsers and VPNs, exist largely because users have grown wary of how their location travels online. Developers who build these protections in from the start earn that trust back.
