Choose an iPhone photo vault by checking storage location, access, recovery, export, subscription boundaries, backup behavior, and deletion risk. Apple Photos may be enough for basic hiding. A separate vault earns its place only when its additional code, organization, and recovery model solve a problem you actually have.
This is a first-party decision guide
The Calculator Lock team wrote this guide. We have a commercial interest in private photo vaults, and the product-specific section describes our own app. We are not presenting an independent ranking or claiming hands-on tests of every competitor.
The useful question is not which app has the longest feature list. It is whether you understand the storage and recovery model before trusting it with the only copy of an important photo.
Start with Apple Photos when its one collection is enough
Apple Photos already includes a Hidden collection. On iOS 16 and later, it is locked by default and requires authentication to open. Hiding removes items from the Library, ordinary albums, and the Photos widget while keeping them inside the Photos library.
Read Apple’s current Hidden album instructions before installing another app. The built-in option is a strong fit when you need basic hiding and are comfortable using the iPhone authentication system.
Compare seven boundaries before importing
| CHECK | QUESTION TO ANSWER |
|---|---|
| Storage | Is the protected copy local, provider-hosted, or synchronized between devices? |
| Access | Does it use iPhone authentication, a separate code, or both? |
| Recovery | What must you save, and can support access the content? |
| Export | Can you retrieve selected items and the full collection while access is active? |
| Subscription | Which actions stop when a subscription ends? |
| Backup | Does the app offer cloud backup, rely on device backup, or exclude its data? |
| Deletion | What happens to the protected copy when the app is removed? |
Apple explains that iCloud Photos synchronizes changes, while iCloud Backup can include eligible app data that is not already synced. A vault should document its own behavior rather than letting you assume either model applies.
Calculator Lock fits a specific local-vault need
Calculator Lock is designed for people who want a working calculator on the surface and a separately coded private vault for photos, videos, files, and notes. Vault content and sensitive vault metadata are encrypted locally. The launch version has no Calculator Lock account, developer content server, cloud backup, or cross-device sync.
- The ordinary calculator remains available without Premium.
- The private vault currently requires an active Premium entitlement.
- Current purchase options are weekly and annual subscriptions, with localized terms shown by the App Store and RevenueCat.
- If Premium ends, existing encrypted content remains accessible and exportable; adding new content requires renewal or restore.
- As explained in Calculator Lock’s privacy policy, RevenueCat receives anonymous purchase history and transaction status for entitlement and subscription functions. It does not receive vault content.
The model is a poor fit if you require built-in cloud backup or cross-device access. It is a better fit when you specifically want a separate calculator-code flow and accept the responsibility of maintaining local access and exports. Review the Calculator Lock photo vault and the guide to on-device encryption before deciding.
Test with nonessential files before committing
- Import a few files you can afford to keep elsewhere.
- Lock and reopen the app using its normal access flow.
- Review the recovery instructions and save any required recovery material outside the app.
- Open photos at full size and play videos.
- Test a selected export and locate the complete-export workflow.
- Read what happens when Premium ends and when the app is deleted.
Keep the original files until the test is complete. The photo vault recovery and export checklist explains how to verify a portable copy before uninstalling or switching apps.
