App Locker Fingerprint Applock: Useful Vault, Unclear Privacy

30-Second Take

App Locker Fingerprint Applock does the basics well: it locks individual Android apps, hides photos and videos, and supports PIN, pattern, and fingerprint access. The app is free to install, has a 4.0 rating from 22,300 reviews, and has passed 10 million downloads. That reach suggests it works for many people, but it does not prove the vault is the safest place for sensitive files.

The biggest concern is privacy, not the lock screen. A security app needs deep access to your phone, and the listing’s broad feature set—app locking, media storage, contacts, messages, and intruder selfies—means you should inspect its permission requests before moving private content into it.

Features and Pricing

App Locker Fingerprint Applock is available on Android, with support starting at Android 7.0. The Google Play listing shows it as free to install, but it includes in-app purchases. The page does not provide a clear price breakdown in the supplied details, so the free download should not be treated as proof that every feature is free.

The main tools are straightforward:

• App locking: protect individual apps with a PIN, pattern, or fingerprint.
• Photo and video vault: move selected media out of the visible gallery.
• Intruder selfie: capture an image after failed unlock attempts.
• Message and contact protection: add privacy controls around personal conversations and contact information.
• Custom themes: change the appearance of the lock screen.

The listing describes instant locking when a protected app opens. That is useful because a delayed lock defeats the point, but the page does not state the exact delay, retry limit, encryption method, or recovery process if you forget the password. Those missing details matter more than another lock-screen theme.

Where It Wins

The app covers several privacy jobs in one place. You do not need a separate app locker and gallery vault, and fingerprint support makes repeated unlocking less annoying than typing a PIN every time. The intruder-selfie feature is also practical on a shared phone: it can show who tried to open a protected app.

The rating is respectable rather than spectacular. A 4.0 out of 5 from more than 22,000 reviews gives the app a meaningful user base, while the 10M+ download count suggests it is not an obscure experiment. Still, those figures say more about popularity and basic usability than about the quality of its security.

Compared with Android’s built-in app-lock tools on some manufacturers’ phones, this app may offer broader coverage across brands. Compared with a dedicated vault such as Keepsafe, its appeal is the combination of app locking and media protection rather than a clearly documented privacy architecture.

• ✅ Free to install on Android
• ✅ Supports PIN, pattern, and fingerprint access
• ✅ Combines app locking with a photo and video vault
• ✅ Intruder selfie can reveal failed access attempts
• ✅ Works on older devices running Android 7.0 or later

Watch Out For

The app’s privacy claims are vague. The listing says it requests only essential permissions, but it does not spell out the complete permission list in the supplied page content. A locker that protects apps and reads or manages media may need powerful access, so check the Android permission screen before granting anything unrelated to those tasks.

The vault also creates a single point of failure. If the app is removed, breaks after an update, or loses access to its stored files, recovery may be difficult. The listing does not explain whether hidden media is encrypted, where it is stored, or how backups work. “Invisible” is not the same as encrypted.

There is no iPhone version listed, and the app’s feature list is broader than its technical documentation. That combination makes it less appealing for highly sensitive material. Use it for casual privacy—private screenshots, a personal gallery, or a locked messaging app—not as the only protection for identity documents or irreplaceable photos.

• ❌ Android only
• ❌ In-app purchases are present, but prices are not clear from the supplied listing details
• ❌ Encryption, backup, and account-recovery details are not explained
• ❌ Broad privacy features may require sensitive device permissions
• ❌ A 4.0 rating leaves room for inconsistent performance or support

Best Fit

Choose this if you use an Android phone running version 7.0 or newer, want a free first layer of privacy, and mainly need to stop family members or casual snoops from opening selected apps and gallery items. It is also useful for someone who wants fingerprint unlocking and an intruder photo without installing separate tools.

Skip this if you use an iPhone, need documented encryption and dependable recovery, or plan to store passports, financial records, or other files that cannot be replaced. In that case, use your phone manufacturer’s built-in secure folder where available, or compare a dedicated vault whose encryption and backup practices are clearly published.

Before adding media, test the app with non-sensitive files. Lock one app, restart the phone, try a wrong password, and confirm that the vault still opens. Then review permissions and in-app purchase prompts. Five minutes of testing is cheaper than discovering a recovery problem after hiding your only copy of something important.

Final Verdict

App Locker Fingerprint Applock is best for Android users on a tight budget who need casual app and gallery privacy, fingerprint access, and an intruder selfie. Its 10M+ downloads and 4.0 rating support the basic usability case, but the unclear encryption and recovery details keep it out of the serious-security category.

Use it as a convenience lock, not a vault you blindly trust. For sensitive files, pick a built-in secure folder or a dedicated privacy app with transparent encryption, backup, and permission documentation.
