Best photo vault app for iPhone: Hidden album vs vault apps

Short answer: for most people, the built-in Hidden album is enough. It's free, locked with Face ID by default since iOS 16, and you can check it under Settings > Apps > Photos > Use Face ID. A vault app only makes sense if you want photos out of the Photos app and out of iCloud: Keepsafe charges $9.99/month or $23.99/year, Private Photo Vault's in-app purchases go up to $39.99, and Nino's vault is part of Nino Pro (from $5.99/week, $34.99/year with a 7-day trial, or $44.99 lifetime). Prices checked on the US App Store on 09/27/2026.

I spent time with all four options, and the real question isn't which app has the nicest padlock icon. It's where your files physically live, who can get to them, and what happens the day you delete the app by accident. If you want to try Nino's vault after reading, you can download Nino on the App Store or on Google Play. But read the Hidden album part first: it might already do the job.

The iOS Hidden album: the free vault you already have

A lot of people go looking for the best app to hide photos on iPhone without realizing Apple already built most of it. When you hide a photo, it moves to the Hidden album and disappears from your Library, other albums and even the Photos widget on your Home Screen (Apple spells this out on its support page).

How to hide a photo

• Open Photos, then touch and hold the photo (or tap Select to grab several).
• Tap Hide and confirm.
• To find it again: Photos > Collections, scroll down to Utilities > Hidden, then tap View Album.

How to lock photos on iPhone with Face ID

On iOS 16 and later, the Hidden album is locked by default. To make sure it is on your phone: go to Settings > Apps > Photos and check that "Use Face ID" is turned on ("Use Touch ID" or "Use Passcode" depending on your model). On iOS 16 and 17 there was no Apps menu yet, so it's just Settings > Photos. That same switch also locks Recently Deleted, which matters: without it, anyone could scroll through what you just deleted.

On the same screen you can turn off Show Hidden Album. The album then vanishes from the Photos app entirely, which is handy if your kid or roommate borrows your phone a lot.

Bottom line: great against someone glancing over your shoulder, weaker if the problem is a person who knows your passcode or can get into your iCloud account.

4 questions to ask before you install a vault app

Every listing looks the same: a padlock, a dark background, "ultra secure". To sort them out, I ask the same four questions every time.

1. Where are the files stored?

Either only on your iPhone, or (also) on the developer's servers. A developer cloud is convenient when you switch phones. It's also one more company holding your most private photos. Neither answer is wrong, but you should know which one you're picking. There's more on that in our piece on cleaner apps and photo privacy.

2. Real encryption or just a PIN?

A PIN screen when the app opens tells you nothing about how the files are stored. Look in the listing or the developer's FAQ for what's encrypted and how. Be wary of vague lines like "military-grade security" with no detail behind them.

3. What happens if I delete the app?

This is THE question nobody asks until it's too late. On iOS, deleting an app deletes its local data. If your vault only lives in the app and there's no backup with the developer, your photos go with it. Before you uninstall any vault, move your photos back to your library.

4. What does it actually cost?

Check the In-App Purchases section of the App Store listing, not only the banner inside the app. And know how to cancel: on iPhone it's always Settings > [your name] > Subscriptions (step by step in our guide to canceling an app subscription).

Keepsafe, Private Photo Vault and calculator vaults

Keepsafe

Keepsafe is one of the best known names, rated 4.7 from around 383K ratings on the US App Store. Its pitch is a private cloud: the listing mentions a "Private Cloud" that stores up to 10,000 items, a "Space Saver" feature that compresses photos and saves originals to the cloud, and encryption described as "military-grade". Pricing in the US: $9.99/month or $23.99/year for Premium (checked 09/27/2026).

The upside is real: lose your iPhone and your vault isn't lost with it. The trade-off is that your photos go through Keepsafe's servers. Whether that's OK for this kind of content is your call. If that's the part that bugs you, that's the main reason people look for a Keepsafe alternative.

Private Photo Vault

Private Photo Vault (Pic Safe) sits at 4.8 with about 1M ratings on the US App Store, is rated 16+, and its in-app purchases range from $5.99 up to $39.99 (checked 09/27/2026). It offers a "Cloud Vault" backup described as encrypted, with a Cloud Vault password that the developer says isn't stored on its servers. The logical flip side: forget that password and don't expect support to recover it.

Calculator vaults

You've seen them: a calculator icon, and typing a code opens a stash of hidden photos. The point is disguise, since the app doesn't look like a vault. There are a lot of them, quality varies wildly, and I won't single one out without testing it properly. Run them through the four questions above, especially 1 and 3. And remember the disguise doesn't do much against someone who knows the trick.

Nino Pro's vault: what it does and what it doesn't

Disclosure: Nino is our app 🐿️. It's a photo cleaner first, and the vault is a Nino Pro feature, not a free extra. Better to say that up front.

How it works

• Photos you add leave your camera roll: they're no longer in Photos or in iCloud Photos.
• They're stored in the app's private space on the iPhone, encrypted at rest by the system (iOS Data Protection).
• The vault opens with Face ID (or your passcode).
• Nothing is sent to a server. Like the rest of Nino, everything happens on the device.
• Any photo in the vault can go back to your library in one tap.

The honest trade-off

No cloud also means no backup on our side. If you delete Nino or lose your iPhone, what's in the vault can't be recovered by us. If you plan to uninstall, move your photos back to the library first. That's the price of a vault that shares nothing with anyone.

The rest of Nino

The vault comes with the rest of the app: similar photo sorting (Nino keeps the best shot), swipe mode (left = trash, right = keep, covered in our roundup of swipe photo cleaners), screenshots, large photos, a video compressor (Pro) and a trash you can recover from for 30 days. No fake gigabyte counter, the price shown is the price charged, and you can cancel in 2 taps.

Yes, we have a weekly plan too. If the vault is the main reason you'd pay, the yearly or lifetime option makes a lot more sense. And if you'd rather avoid subscriptions altogether, have a look at our list of cleaners without a subscription.

So which one should you pick?

Here's how I'd call it depending on what you're after:

• You just don't want certain photos popping up when you hand someone your phone: the Hidden album, with Face ID on and Show Hidden Album turned off. Free, nothing to install.
• You want everything back on a new iPhone without thinking about it: a cloud vault like Keepsafe, knowing your photos sit with the developer.
• You want photos out of Photos and iCloud, with no server involved: an on-device vault like Nino Pro's, keeping in mind the loss risk if you delete the app.

Whatever you pick, test it with two or three throwaway photos before trusting it with anything that matters. Add, close, reopen, move back to the library. You'll know quickly whether it fits. And if you're still wary of this app category in general, our piece on whether iPhone cleaner apps are a scam lists the red flags worth watching for.

FAQ

How do I lock the Hidden album on iPhone?

Go to Settings > Apps > Photos and turn on "Use Face ID" (or Touch ID / Passcode depending on your iPhone). It's on by default since iOS 16; on iOS 16 and 17 the path is Settings > Photos.

The same switch also locks the Recently Deleted album.

What happens to my photo vault if I delete the app?

It depends on the app: if your photos only live inside the app, deleting it wipes the vault. Keepsafe or Private Photo Vault can restore what was backed up to their cloud, while Nino's on-device vault can't be recovered.

Before uninstalling any vault, move your photos back to your library.

What is the best free app to hide photos on iPhone?

The free option is already on your phone: the Hidden album in Photos, locked with Face ID. Third-party vault apps usually charge for their full features (Keepsafe is $9.99/month on the US App Store, checked 09/27/2026).

Are hidden photos still in iCloud?

Yes, if iCloud Photos is on, hidden photos stay in iCloud and are hidden on all your devices. To get them out of iCloud, you need to move them into an on-device vault outside the Photos app.

Can someone who knows my passcode open the Hidden album?

Yes, the Hidden album lock accepts Face ID, Touch ID or your iPhone passcode. If someone knows your passcode, change it before you go shopping for a vault app.
