> Compare Apple's built-in locks, Proton Drive, Cryptomator, 1Password and Filevale for keeping sensitive files private on iPhone, with honest limits.

There is no single best private vault for iPhone; it depends on whether you want to hide photos, store documents or share them. Apple's built-in locks are enough for casual privacy, Proton Drive and Cryptomator suit encrypted cloud storage, 1Password suits documents next to your passwords, and Filevale suits a vault on the phone with an encrypted ZIP for sharing. Prices and features change, so check each app's current page.

Why now? From iOS 27.3 Apple checks items shared with Anyone with the link and says they are not end-to-end encrypted. The check is tied by press to child safety, and this guide is not about avoiding it. It is about where ordinary sensitive files, such as IDs, contracts and medical papers, should live instead.

## Apple's built-in options

**Strengths:** already on your iPhone, integrated, no extra account. Locked Notes are end-to-end encrypted for iCloud accounts, and the Hidden album opens with Face ID. Advanced Data Protection extends end-to-end encryption to more iCloud categories.

**Limits:** Notes cannot lock notes that contain PDFs or file attachments, per Apple. Hidden only holds photos and videos, and ADP does not cover public links. See [Notes lock vs Hidden album vs a vault app](/guides/notes-lock-vs-hidden-album-vs-private-vault-app/).

## Proton Drive

**Strengths:** cloud storage from Proton with end-to-end encryption. Share links can have a password and an expiry, and files stay end-to-end encrypted according to Proton. It works across platforms.

**Limits:** it is a cloud drive, not a lock screen for your camera roll, and it needs a Proton account. Storage plans are limited, so check the current tiers.

## Cryptomator

**Strengths:** open source, it encrypts files on your device before they reach the cloud service you already use. Good if you want your own storage (iCloud Drive, Dropbox, Google Drive) with client-side encryption.

**Limits:** a more technical setup. The iPhone app has a paid unlock for full use, so check the App Store before relying on it.

## 1Password

**Strengths:** keeps documents and secure notes next to your passwords, encrypted, with sharing inside its own system. A solid choice if you already use it.

**Limits:** it is a password manager first and a subscription product, and is not designed for large file collections.

## Filevale

**Strengths:** the Filevale iPhone app has a Vault locked with a passcode or a pattern, with a 12-word recovery key. Share privately (Pro) turns a file into an AES-256 password ZIP, iCloud Vault backup (Pro) keeps an encrypted copy of the vault in your own iCloud, and a Privacy hub helps clean photo metadata. The app processes files on your device and its privacy label says Data Not Collected. It also has more than a hundred conversion tools. Details at [Filevale for iPhone](/go/ios?src=web-vault-apps).

**Limits:** a young app next to established names, and you must guard the recovery key. Some features need Pro, so check the current plan and prices in the App Store listing before you decide.

## How to choose

- **Hide a few photos from casual view:** Apple's Hidden album.
- **Keep passwords and short notes:** locked Notes or a password manager.
- **Store files with end-to-end encrypted cloud sync:** Proton Drive or Cryptomator.
- **Keep sensitive files locked on the phone and make encrypted ZIPs to send:** a vault app such as Filevale.
- **Send a file once:** skip apps and use an AES-256 ZIP.

[Password-Protect ZIP](/zip-with-password/) is the browser version of the same step and runs on your device. Clean hidden details first with [Remove Metadata](/remove-metadata/). See also [encrypted ZIP vs an iCloud public link](/guides/encrypted-zip-vs-icloud-public-link/).

## Frequently asked questions

### Which private vault app is the most secure?

Security depends on the design, the lock you pick and how you handle recovery. Apps that encrypt on your device and let you keep the recovery key offline are stronger than any app with a weak four-digit code.

### Are vault apps safe from Apple's iCloud link checks?

The checks Apple described apply to items shared by Anyone with the link. A vault that stays on your device does not create a link. Do not read this as a way to dodge any policy; it is about keeping private files private.

### Do I need a vault if I use Advanced Data Protection?

ADP encrypts what you keep in iCloud but not items behind a public link. A vault adds a lock inside the phone, which helps if someone else uses your unlocked device.
