NestLock: App Lock Photo Vault

Share your phone without sharing your private life.

You open one photo for a friend, hand a game to your child, or pass your phone to a coworker. Your chats, banking apps, gallery, and personal videos should not come with it. NestLock is an app lock and photo vault made for these everyday moments. Protect apps with a PIN, pattern, or fingerprint lock, hide photos and videos in an encrypted vault, and stay in control when someone else has your phone.

HAND OVER YOUR PHONE WITH CONFIDENCE

Choose any installed app and place a lock screen in front of it. Keep WhatsApp conversations private, stop an accidental tap from opening a banking app, or use NestLock as a gallery lock before sharing your device. Unlock with the PIN, pattern, or fingerprint you choose.

KEEP PERSONAL PHOTOS OUT OF SIGHT

One swipe should not reveal something personal. Move private photos and videos into the encrypted photo and video vault so they are hidden from your regular gallery. When you want to hide photos or keep videos separate, your vault gives them a private place protected by your lock.

Need a backup you control? Vault Backup creates an encrypted ZIP export locally for you to save or move yourself. It is not a cloud backup, and NestLock does not upload your vault to cloud storage.

KNOW WHEN SOMEONE TRIES TO GET IN

Wonder who entered the wrong PIN? Enable intruder selfie and NestLock uses the front camera to capture an attempted unlock. Review the photo later instead of guessing who tried to open a protected app.

MAKE PRIVACY FIT YOUR DAY

Use schedule lock to protect distracting or sensitive apps automatically during work, study, bedtime, or kids’ screen time. Choose the days and hours for each app; outside that schedule, it opens normally.

KEEP THE VAULT OUT OF PLAIN SIGHT

App disguise can make NestLock appear on your launcher as Calculator, Clock, Notes, or Files. The calculator vault style keeps a privacy app from standing out while your real protection remains behind your lock.

MAKE EVERY UNLOCK FEEL LIKE YOURS

Choose from 35+ lock-screen themes, including Aurora, Sakura, Dracula, Vaporwave, and Tokyo Night, or use your own photo as a custom background.

MORE CONTROL, WITHOUT MORE COMPLEXITY

A separate Master Lock PIN protects NestLock’s own settings. Security Score shows how your protection setup is configured and points you toward options you can enable. NestLock supports 11 languages, so more people can set up privacy protection in the language they prefer.

PRIVATE ON YOUR DEVICE

Core protection works offline. There is no account to create, and NestLock does not collect personal data. Your app-lock processing and encrypted vault stay on your device. No vault content is stored in the cloud; the optional Vault Backup is the local export described above.

Whether you want an app lock for chats and banking, a photo vault to hide photos, a gallery lock for shared-phone moments, a fingerprint lock for quick access, a calculator vault disguise, an intruder selfie, or a schedule lock that follows your routine, NestLock keeps privacy practical.

ACCESSIBILITY SERVICE DISCLOSURE

NestLock uses Android Accessibility Service only to detect when a protected app is opened so it can display the lock screen. The service does not read your messages, passwords, keystrokes, personal information, or screen content. All processing happens locally on your device, and no personal data is collected or transmitted.
