Lending someone your phone should not mean giving them access to every personal photo or document. Calendar Vault is designed to add a separate access barrier around selected files while presenting an everyday calendar interface.
According to its developer description, the Android app combines private storage for photos, videos, contacts, and documents with calendar events, tasks, and weather information. Here is how its advertised features work and what to check before using it.
What Is Calendar Vault?
Calendar Vault is a privacy app that places a protected vault behind a functional calendar. You can use its calendar tools for scheduling while keeping selected personal content inside the vault.
The calendar appearance is intended to reduce casual attention when someone borrows your phone. However, a disguised interface does not make an app invisible or replace the protection provided by authentication and encryption.
Store Photos, Videos, Contacts, and Documents
The developer lists four main types of content that Calendar Vault supports:
| Content | Intended use |
|---|---|
| Photos | Keep selected personal pictures inside the vault |
| Videos | Store private recordings separately |
| Contacts | Maintain private contact entries within the app |
| Documents | Store PDFs and other important files |
After importing content, check whether the original remains elsewhere on your phone. Copies in your gallery, downloads folder, messaging apps, or cloud storage may still be accessible outside the vault.
Likewise, storing a contact privately should not be assumed to remove that person’s details from synced accounts, messages, or call history.
PIN and Fingerprint Protection
Calendar Vault advertises PIN and fingerprint authentication. Its setup instructions describe support for a PIN containing four to nine digits.
Choose a PIN that is difficult to guess and avoid obvious combinations such as repeated digits or birthdays. If supported by your device, fingerprint access can make everyday unlocking more convenient.
The availability of both methods does not necessarily mean the app requires both during every unlock.
Advertised AES-256 Encryption
The developer states that Calendar Vault encrypts vault content using AES-256.
Encryption is designed to protect stored information from being read without the necessary key. However, an encryption label alone does not establish how securely an app handles keys, recovery, or exported files.
The features described here are based on the supplied app description, rather than hands-on testing or an independent security audit.
A Calendar You Can Use Every Day
Calendar Vault’s advertised scheduling features include:
- Events and tasks.
- Day, week, and month views.
- Location-based weather information.
- A simple calendar interface.
These tools give the app a practical purpose beyond private storage. Weather functionality may require location access and an internet connection, so review permission requests when enabling it.
Decoy PIN Mode
The app description includes an optional fake PIN that displays an empty decoy vault.
This creates an alternative view when the decoy PIN is entered. It should not be treated as proof that the real vault cannot be discovered or as guaranteed protection if someone pressures you to unlock your device.
Fingerprint Recovery With a Secret Date
According to the developer’s instructions, users can configure fingerprint recovery using a secret calendar date. Tapping that date five times triggers fingerprint authentication.
Configure and test recovery before storing important content. Recovery depends on the supported setup and should not be understood as a promise that access can never be lost.
This feature also does not replace a backup: unlocking the app and recovering files from a missing or damaged phone are different problems.
Customize the App Icon and Name
Calendar Vault advertises multiple icon styles inspired by popular phone interfaces. It also describes display-name choices such as Calendar, Planner, Agenda, and My Day.
These options help the app blend into your home screen. They do not necessarily conceal its presence in Android’s installed-app list or system settings.
Local Storage and Manual Backups
The developer describes vault storage as local to the device, with no built-in cloud backup. A manual export feature is provided for creating backup copies.
Keep a separate backup of files you cannot afford to lose.
Before uninstalling Calendar Vault, clearing its app storage, resetting your phone, or switching devices:
- Export the files you need.
- Confirm that the exported files open correctly.
- Store a protected backup somewhere separate from the phone.
- Check the app’s instructions for restoring or importing your content.
The supplied description does not confirm whether exports remain encrypted. Check the export format and protect the destination accordingly.
How to Set Up Calendar Vault
- Open the Calendar Vault listing on Google Play.
- Review the current app details, permissions, and Data safety information.
- Install the app and follow its onboarding instructions.
- Create your PIN and configure supported fingerprint options.
- Import a non-sensitive test photo or document.
- Try opening and exporting it.
- Check whether its original copy remains outside the vault.
- Add private content after confirming how storage and recovery work.
Testing with an unimportant file first helps you understand the app without risking your only copy of something valuable.
Privacy Details to Review
The supplied description claims no ads, tracking, or personal-data collection. These statements have not been independently verified for this article.
Read the current privacy policy and compare it with the permissions requested by your installed version. The developer’s instructions place the policy under Settings → Privacy Policy.
Local storage of vault content does not automatically mean that every app feature operates offline. Weather and other connected features should be assessed separately.
