Folder Lock

Lock photos and files with PIN pattern password or fingerprint

Folder Lock focuses on one task and does it well: keeping private content out of sight. It creates secure spaces on your device where you can place photos, videos, notes, voice memos and other sensitive items, then seal them behind your choice of PIN, pattern, full password or fingerprint. That flexibility makes it easy to pick the protection method you prefer without sacrificing security.

A standout strength is its vigilance against prying eyes. The app can alert you to suspected break-in attempts so you know when someone has tried to guess their way in. If you want to be even more discreet, a stealth mode can hide the launch icon entirely. Accessing the vault is still possible by dialing a code on your phone, with *3300 restoring the icon when needed. For extra resilience, you can back up locked content to the cloud, including support for Dropbox, which helps keep valuables safe if your device is lost or damaged.

There are trade-offs to consider. Folder Lock includes ads, which might distract from the otherwise focused experience. It may also request permissions related to tracking usage on other apps, a privacy consideration worth reviewing before you commit to its features. Stealth mode is powerful, but it does require you to remember the dial code to bring the app back.

For anyone who shares a device with family or coworkers, or simply wants tighter control over personal files, Folder Lock offers a practical toolkit. Multiple lock types, intrusion alerts, a hidden mode and cloud backup give you a well-rounded way to protect what matters, provided you are comfortable with the permission requests and occasional advertising.
