Checks include features that may require a paid plan or supported device. “Not documented” means we could not confirm the feature from the reviewed sources; it does not mean the feature is absent.

Important feature differences
  1. Keepsafe cloud privacy: the comparison marks zero-knowledge backup as unavailable, based on its specific content-access policy and the feature information supplied by Private Photo Vault®. That policy allows limited technical access for support, legal or policy-enforcement purposes. A separate overview says staff cannot access content; that wording differs from the specific policy. This is not an independent audit of its encryption.Source: https://support.getkeepsafe.com/hc/en-us/articles/360035082512-Can-Keepsafe-see-any-of-my-content
  2. Apple cloud privacy: iCloud Photos can use end-to-end encryption with Advanced Data Protection where available. Standard protection uses Apple-held keys. Enabling the Hidden album alone does not turn on Advanced Data Protection.
  3. Calculator#: NewSoftwares.net’s product guidance lists private albums and decoy vaults. Plan and platform availability may differ. A calculator disguise or fake error screen alone is not a decoy vault.
  4. Apple Photos vs Hidden: Photos has albums, folders and duplicate detection. Hidden photos are kept out of other albums, so the album rows compare organization inside the private collection. The duplicate-detection check credits Photos generally; scanning the Hidden collection was not verified.

Encryption and zero-knowledge backup are different: encrypted files may still be readable by a provider that holds the keys. The encryption row reflects documented protection, not an independent security audit. Calculator#’s app-level encryption was not confirmed in the reviewed listing; this does not mean its device storage is unencrypted.

WiFi Transfer means direct local transfer through a computer browser, not cloud sync over WiFi. Calculator# has iPhone and Android versions, but cross-platform vault sync was not confirmed.

A CLOSER LOOK

Key differences between the apps

PRIVATE PHOTO VAULT® VS KEEPSAFE

Who can access your cloud files?

Keepsafe combines a separate PIN with account-based backup. Its support policy says it is not completely zero-knowledge: staff can technically access content in limited support, legal or policy-enforcement cases. The comparison therefore marks zero-knowledge backup as unavailable. The source notes explain the difference between that policy and its general product overview.

With Private Photo Vault®

Cloud Vault encrypts photos and videos locally using your key before upload. Our team cannot view that content. You can also use the on-device vault without an account.

Understand Cloud Vault
PRIVATE PHOTO VAULT® VS CALCULATOR#

Combine a discreet icon with vault protection.

Calculator# by NewSoftwares.net offers a calculator disguise, multiple lock methods, file storage and third-party cloud backups. The reviewed product documentation does not explain who controls encryption keys or whether backup providers can read files.

With Private Photo Vault®

Choose a discreet app icon, plus documented AES encryption for local files and Cloud Vault. Organize photos and videos in albums and sub-albums, and sync between iPhone and Android.

PRIVATE PHOTO VAULT® VS APPLE HIDDEN ALBUM

A different code from your phone.

Apple’s Hidden album is free and built in. It keeps selected media out of the main library and is locked by default on current iOS. It uses device authentication, including Face ID, Touch ID or your device passcode, rather than a separate album password.

With Private Photo Vault®

Choose a different vault code, even when someone knows your phone’s code. Add password-protected albums and, on supported devices, require Face ID and your vault PIN together.

Comparison questions

What does zero-knowledge mean here?

For Cloud Vault photo and video content, it means we do not have the secret needed to decrypt your files. Encryption happens on your device using your key. This also means we cannot recover a forgotten Cloud Vault password. It does not mean the service has no account or billing information.

Is Apple’s Hidden album encrypted?

It is protected by Apple’s device security. Hiding an image is not the same as setting a separate vault password. For iCloud Photos, Apple’s standard protection encrypts files in transit and at rest with Apple-held keys; optional Advanced Data Protection provides end-to-end encryption for Photos where available. We do not describe Apple’s photos as unencrypted.

Does Keepsafe require cloud backup?

Keepsafe’s setup guide requires an account, while its support documentation describes a switch to enable or disable cloud backup. The reviewed documents do not establish the default setting for every current version.

Can I move from another photo vault?

Use the existing app’s export options, then import your photos and videos into Private Photo Vault®. Check that files open correctly before removing any originals or deleting your old app. See our import tutorial.
