If you've been using Apple's "Hidden Album" to keep private photos away from prying eyes, we have bad news: it's not actually private.

Anyone who picks up your iPhone can open the Photos app, scroll to the bottom of the sidebar, tap "Hidden," and see everything. There's no password, no PIN, no encryption. It just… hides the photos from your main feed.

In this guide, we'll cover four methods to truly hide photos on iPhone β€” ranked from the most basic to the most secure.

Method 1: Lock the Hidden Album (iOS 16+)

Apple added a Face ID lock to the Hidden Album starting with iOS 16. To enable it:

  1. Open Settings
  2. Scroll down to Photos
  3. Toggle on "Use Face ID" (or Touch ID)

This is better than nothing β€” someone would need to pass Face ID to view hidden photos. But the photos still exist on your device, unencrypted, in a folder that's labeled "Hidden." Anyone with technical file system access (via a computer, backup tool, or jailbreak) can find them.

Limitation: The Hidden Album is still visible in the sidebar. People know something is there. It provides obscurity, not real security.

Method 2: Create a Locked Notes Folder

Apple Notes supports locked notes with Face ID. You can import photos into a locked note, which adds a layer of protection.

This works for a few photos but becomes impractical at scale. Notes aren't designed for media storage, and you can't easily browse a grid of photos. More importantly, the photos are still copied to your Notes folder β€” they're not removed from your camera roll automatically.

Method 3: Screen Time Lock on Photos App

You can use Screen Time to add a passcode requirement to the Photos app itself:

  1. Settings β†’ Screen Time β†’ App Limits
  2. Add a limit for Photos
  3. Set the time to 1 minute per day
  4. Set a Screen Time passcode (different from your device PIN)

The result: accessing Photos requires the Screen Time passcode. This is a creative workaround but it's clunky β€” you're limiting your own Photos access, and it doesn't work well day-to-day. Also, photos are still completely unencrypted on the device.

Method 4: Use an Encrypted Vault App (Most Secure)

The most secure approach is to move private photos completely out of your Photos library and into an encrypted vault app β€” one that:

This is exactly what Calculator Vault does. When you import a photo:

  1. Calculator Vault reads the original photo
  2. Encrypts it with AES-256-GCM using a key stored in your device's Keychain
  3. Saves the encrypted blob with a random filename (e.g., a3f7b2c9.vault)
  4. Deletes the original from your Photos library

What's left on your device is an encrypted file. Even if someone plugs your phone into a computer, they see random blobs of data β€” not photos.

πŸ’‘ Bonus: Calculator Vault looks exactly like a calculator. The app icon can be changed to look like Notes, Weather, or Clock. There's no visible "vault" anywhere on your home screen.

Which Method Should You Use?

Method PIN Protected Encrypted Invisible
Hidden Album (locked) βœ“ Face ID βœ— βœ—
Locked Notes βœ“ Face ID Partial βœ—
Screen Time lock βœ“ Passcode βœ— βœ—
Calculator Vault βœ“ PIN + Face ID βœ“ AES-256 βœ“ Calculator disguise

For casual privacy (keeping nosy friends out), locking the Hidden Album with Face ID is probably enough. For genuine security β€” partners, parents, or anyone with physical access to your device β€” an encrypted vault app is the only approach that actually works.
