GeoLocker

Location-based security for iPhone, iPad and Mac

Lock your most sensitive notes, photos, video and files into vaults tied to a place. Choose biometric vaults protected by the Secure Enclave, or hidden vaults that open with a map spot plus a passphrase and leave no trace they exist. Everything that protects you is free.

A spot on the map plus a passphrase. Get either one wrong and it looks like there's nothing there.

Vaults tied to a place

Create a vault in seconds

Open a hidden vault

New in Version 3.1

Two of these save you time. The third is for when you can't get to a vault's spot, and it stays off until you switch it on.

Add several at once

Pick a batch of photos or files and they all go into the vault together. No more adding them one by one.

See how big a vault is

Biometric vaults now show how much they're holding, so you can tell what's piling up inside.

Unlock Anywhere opt-in

Sometimes you need to open a vault when you're nowhere near its spot. Switch this on and a biometric vault opens with just Face ID or Touch ID, or a hidden vault with just its passphrase. It starts off, because giving up the location leaves one less thing guarding the vault, and the app has you confirm that first.

Core Capabilities

Location-Bound Vaults

Each vault is tied to a place. Biometric vaults can require you to be there; hidden vaults bake the spot into the key itself.

In-Person or Map Unlock

Open a vault by being at its location, or, if you allow it, by pointing at the spot on the map.

Hidden (Deniable) Vaults

Opened by a map spot plus a passphrase. A wrong spot or passphrase looks exactly like “nothing here,” so no one can prove a hidden vault exists. Includes decoys and a duress wipe.

Secure Enclave Encryption

Biometric vaults each get their own key, generated in the device’s Secure Enclave and released only by Face ID / Touch ID. AES-256-GCM throughout.

Multiple Vaults

Create separate encrypted vaults for home, work or family. Each one is independent, with its own location and keys.

Configurable Unlock Zones

Set each biometric vault’s unlock radius from 5 to 100 meters, including the device’s reported GPS accuracy.

Notes, Photos, Video & Files

Store text, photos, video, audio recordings and documents with the same encryption.

On-Device & Private

Your vaults never leave the device. No cloud, no accounts, no analytics or tracking. Core security works fully offline.

Most apps protect your data. GeoLocker can hide that it exists.

Plenty of apps encrypt your files. The catch is that the lock is obvious: anyone holding your phone can see you have a vault and pressure you to open it. GeoLocker's hidden vaults take that pressure point away.

A hidden vault opens only with a secret place on the map and a passphrase. Both are mixed straight into the encryption key, so there's nothing stored to check a guess against. Enter the wrong spot or the wrong passphrase and you get the same blank result as a phone with nothing on it. There's no list of vaults, no count, and nothing on the device that hints any exist.

If you're ever forced to open the app, hand over a decoy vault full of harmless notes while your real vaults stay invisible. You can even arm a duress vault that wipes the others the moment it's opened. That's real plausible deniability, and it's free for everyone.

Why the passphrase is hard to crack: Argon2id

Someone who has your phone can still try to guess a hidden vault's passphrase. GeoLocker makes every guess expensive by deriving the key with Argon2id, the algorithm that won the Password Hashing Competition, is standardised as RFC 9106, and is the one OWASP recommends for password storage.

Argon2id is memory-hard: it deliberately needs a large amount of memory for each attempt, which blunts the GPU and ASIC rigs that tear through ordinary hashes. On GeoLocker that means even on-device guessing is slow, so a longer passphrase and a non-obvious spot are genuinely strong. We're honest about the flip side: a short passphrase at an obvious place can still be guessed. The strength is in your hands.

What it protects against, honestly

No overselling. Here's what each situation looks like, and where the limits are.

Situation	How GeoLocker helps	Honest limit
Lost or stolen phone	Everything is AES-256-GCM encrypted, stays on the device, and auto-locks when the app goes to the background.	Only a risk if the phone is already unlocked with a vault open.
Someone on your unlocked phone	Biometric vaults still need Face ID; hidden vaults need the exact spot and passphrase.	Someone watching over your shoulder as you open one.
Forced to unlock	Hand over a decoy. Real hidden vaults leave no trace, so "there's nothing here" is believable.	Biometrics can be compelled; a known spot and passphrase opens the real vault.
Forensic lab extraction	Hidden vaults are indistinguishable from random filler, so a routine image reveals nothing about them.	A short or obvious passphrase can still be ground down on the device (Argon2id slows this).
iCloud, backup or network	Nothing syncs or leaves the device. No servers, no accounts, no analytics.	Local-only by design.

The same plain-language breakdown lives inside the app, under Settings.

What people are saying

Rated 5 out of 5 on the App Store. A few words from people using it:

★★★★★

Amazingly Unique

This looks like one of the most meticulously designed systems to securely store personal information created by a single person that I've found on the App Store. I also greatly appreciate the thorough descriptions of the technical methods this app uses to achieve its goal.

An interesting concept

A unique way to store secrets. Haven't seen this way of doing it before.

Always wanted an app like this !!

Finally someone implemented it

Protect what matters most

Your data never leaves your device. No cloud, no accounts. With hidden vaults, the location and passphrase are part of the key itself.
