The Short Answer

When a dating app shows “3 miles away,” it sounds vague. It usually isn’t. Most location-based dating apps store your precise GPS coordinates on their servers, even when the screen only displays a rough distance to other users. Researchers have shown, repeatedly, that this combination — precise server-side coordinates plus a public “distance” number — can be reverse-engineered to reveal where someone actually is.

If you care about privacy while dating online, the goal isn’t to disappear. It’s to understand what your app knows, what other users can figure out, and how to tighten the controls without making the app useless.

This guide walks through what the research actually says, which apps let you hide or blur your location, and the practical habits that reduce your exposure day to day.

What “Precise” and “Approximate” Location Actually Mean

Smartphone GPS can locate you within a few meters. Most dating apps ask for permission at that full-precision level, even if what you see on screen is rounded.

There is an important difference between:

  • Approximate location, which is what the app shows — a distance in miles or kilometers, a city name, a neighborhood label.
  • Precise location, which is what the app collects and often stores on its servers — your actual coordinates, often updated every time you open the app.

The gap between these two is where most of the privacy risk lives. You may see “5 km away,” but the app may know exactly which building you’re sitting in.

How Location Data Is Stored and Shared

Based on public research and privacy-policy reviews of major apps:

  • Server-side storage. GPS coordinates are typically transmitted to the app’s servers when you open it and, in some cases, while it runs in the background. This data may be retained for years as part of your profile.
  • Advertising and analytics. Apps with ad-supported tiers may share location data — or behavioral data tied to location — with ad networks. This can include patterns like where you go, when, and how long you stay.
  • Visible to other users. Most apps display a distance to other profiles. Some also reveal a neighborhood or a “nearby” radius. Even that small amount of information can be exploited.

The Trilateration Problem

The technique that makes a “5 miles away” label dangerous is called trilateration. It works like this:

  1. Pick a target profile.
  2. From your real location, draw a circle with a radius equal to the distance the app shows.
  3. Spoof or move your own location to a second known point, record the new distance, draw a second circle.
  4. Repeat from a third point.
  5. Where the three circles intersect is approximately where the target is.

Security researchers demonstrated this publicly years ago. Tinder, Grindr and several other major apps have been shown to be vulnerable at various points. Grindr in particular faced well-documented incidents in which researchers could pinpoint users, a serious concern in regions where being LGBTQ+ is criminalized.

More recent research has shown that even when users disabled the public distance display, certain apps could still leak precise location through other design quirks. One 2024 study of the Hornet app found researchers able to locate users within about 10 meters, even with distance hidden. After Hornet changed its approach, accuracy dropped to roughly 50 meters — better, but still tight.

The practical lesson: if a feature exists to compute your distance to someone else, the math to reverse it often exists too.

What You Can Actually Control

The good news is that users have more levers than they tend to realize.

Permissions on your phone

  • iOS and Android both let you grant “Precise” or “Approximate” location. If your dating app doesn’t need your exact block, set it to approximate.
  • Background location. Turn it off for dating apps. There is rarely a legitimate reason for a dating app to track you when you’re not actively using it.
  • Reset permissions for any dating app you haven’t opened in a month. Long-forgotten apps with stale permissions are a quiet risk.

In-app settings

Different apps offer different controls. Here’s what to look for, based on what public documentation and policy reviews describe:

  • Hide my distance. Some apps let you stop showing your distance to others. This doesn’t necessarily stop the app from collecting your coordinates — but it removes one major leak.
  • Travel mode / Snooze. A few apps (Bumble’s Snooze is one example) pause updates and stop refreshing your visible location. Useful when you want a break without deleting the app.
  • Manual location pin. A small number of apps let you set your location to a fixed point rather than your real-time GPS. This is the cleanest privacy option if you mainly match in one city but don’t want to broadcast your home address.
  • Hide my profile from certain users. Some platforms let you block or hide from specific people, which helps if you have a stalker or an ex on the app.

Account hygiene

  • Don’t reuse photos that already exist on your public Instagram or LinkedIn. Combined with location data, reverse image search makes identifying you much easier.
  • Avoid putting your workplace, gym or home neighborhood in your bio or photos. These are the breadcrumbs that turn “3 miles away” into “the apartment building on the corner.”
  • Use a dedicated email for dating signups so a breach doesn’t cascade into your main accounts.

Which Apps Are Better for Location Privacy?

No app is perfectly private. That said, based on public research and platform documentation:

  • Apps that round distance to the nearest mile or kilometer (rather than showing decimal fractions) make trilateration far harder.
  • Apps that store only approximate location on the server are safer than those that retain precise GPS history.
  • Apps with manual location pinning (you choose the city) leak less than apps that auto-detect via GPS.
  • Apps that have responded to past research findings — and published their mitigations — are preferable to those that have been silent.

Be cautious of any app whose privacy policy uses vague language like “we may share location data with partners.” If they can’t tell you who those partners are, you don’t really know who can see where you are.

A Quick Checklist Before You Open the App

  1. Check your phone’s location permission for the app — precise or approximate?
  2. Disable background location if it’s on.
  3. In the app, hide distance if possible, or pin your location manually.
  4. Remove identifying details from your profile photos and bio.
  5. Use a unique email and a Google Voice-style number if you don’t want your real number circulating.
  6. Snooze or delete the app when you travel somewhere sensitive.

FAQ

Does turning off “Show my distance” actually hide me? Partially. It removes one signal other users can exploit, but the app itself may still collect precise GPS in the background. Check your phone-level permission as well.

Can I just use a VPN to hide my location from the app? A VPN hides your IP, not your GPS. Most dating apps use the phone’s location services, not the network address, so a VPN alone doesn’t help much. You’d still need to spoof or fake the GPS signal at the OS level, which some apps detect and treat as a ban-worthy behavior.

Is approximate location safe enough? It’s safer than precise, yes. A location accurate to a few hundred meters is meaningfully harder to weaponize than one accurate to a few meters, especially when combined with other privacy habits.

Should I delete dating apps before traveling? If you’re going somewhere where your dating identity could put you at risk — for example, a country that criminalizes LGBTQ+ relationships — yes. A separate travel profile on a separate device, used only on hotel Wi-Fi, is the cautious approach.

What should I do if I think someone has located me through an app? Stop using the app, document the messages and any threats, and contact local authorities if you feel unsafe. Most major apps also have dedicated safety teams that can lock or delete an account.

The Takeaway

The distance number on a dating profile isn’t just a number. In the wrong hands, with the right math, it can become a map to your front door. The fix isn’t paranoia — it’s layering: phone permissions set to approximate, distance hidden when possible, profile photos stripped of identifying landmarks, and a willingness to walk away from any app that won’t let you control what it knows about you.

Dating apps are a useful tool. They’re safest when you treat your location like the sensitive data it actually is.
