PLocker Features

Password Vault

The Password Vault is the heart of PLocker, providing a fully encrypted storage system for all your login credentials. Every password you save is protected with AES-256 encryption, ensuring that even if someone gains physical access to your device, your data remains inaccessible without your master password. The vault supports unlimited entries organized into customizable categories and folders, making it easy to manage credentials for work, personal, and financial accounts separately. A powerful search function lets you find any saved password instantly, and the one-tap copy feature streamlines your login workflow without ever revealing your password on screen.

Your Data. Your Device. Your Control.

Password Generator

Weak and reused passwords are the leading cause of account compromises, and the PLocker Password Generator eliminates this risk entirely. With a single tap, it creates cryptographically strong passwords using a customizable mix of uppercase letters, lowercase letters, numbers, and special characters. You define the length from 8 to 64 characters and toggle exactly which character types to include, giving you full control over password strength. The built-in strength meter provides real-time visual feedback using a color-coded bar, so you always know how secure your generated password is. Every password is generated randomly using a secure entropy source, ensuring no two passwords are ever the same.

Uncrackable Passwords. One Tap Away.

Secure Notes

Beyond passwords, your digital life contains sensitive information like recovery codes, software license keys, bank account details, and personal identification numbers that deserve the same level of protection. PLocker's Secure Notes feature provides a dedicated space for storing any type of confidential text information, encrypted with the same AES-256 standard used for your passwords. Each note supports rich formatting and can be organized within the same folder and category system as your password vault. Notes are stored locally in the encrypted SQLite database and never leave your device, ensuring your private documents and personal records stay exactly where they belong.

Sensitive Information. Locked and Local.

Biometric Login

Typing your master password every time you need to access an account can be tedious, and PLocker solves this with seamless biometric authentication. Using your device's built-in fingerprint sensor, you can unlock your vault in under a second without compromising security. The biometric data never leaves your device—PLocker interfaces with the Android Biometric API, which handles authentication at the operating system level, ensuring your fingerprint data is never stored, transmitted, or accessible by the app itself. You can enable or disable biometric unlock at any time, and it remains protected behind your master password as a fallback authentication method.

Your Fingerprint. Your Key. Always Local.

Backup & Restore

Since PLocker is a 100% offline password manager, having a reliable backup system is essential to protect against device loss or failure. The Backup & Restore feature lets you create fully encrypted backup files of your entire vault, including all passwords, notes, categories, and settings, saved directly to your device's local storage. Each backup is encrypted with your master password, meaning the backup file itself is useless without your credentials. Restoration is straightforward: simply select the backup file, enter your master password, and all your data is restored exactly as it was. You can also transfer your data to a new device by moving the encrypted backup file manually.

Manual device-to-device transfer support

Encrypted Backups. No Cloud Required.

Dark Mode

Using a password manager in bright environments or at night shouldn't strain your eyes, which is why PLocker includes a fully designed Dark Mode. Unlike many apps that simply invert colors, PLocker's dark theme has been carefully crafted with proper contrast ratios and muted color palettes to reduce eye fatigue during extended use. The app supports three modes: Light, Dark, and System Default, where it automatically follows your device's system-wide theme setting and switches seamlessly between themes based on the time of day. Every screen, including the vault, generator, notes, and settings, is fully themed and consistent in both modes.

Beautiful by Day. Comfortable by Night.

Offline Security

The defining feature of PLocker is its 100% offline architecture, which fundamentally sets it apart from every other password manager on the market. PLocker does not request internet permissions and has no network code whatsoever, making it physically impossible for your data to be transmitted anywhere. Your entire encrypted database is stored in a local SQLite file on your device, isolated from any external access. This offline-first design eliminates entire categories of risk: no cloud server breaches, no man-in-the-middle attacks, no unauthorized API access, and no third-party data leaks. By keeping everything local, PLocker ensures that you—and only you—have access to your passwords.

Zero internet permissions requested or used

Immune to cloud breaches and server attacks
No network code exists in the application

No Internet. No Cloud. No Compromise.

Screenshot & Share Protection

In today's digital landscape, malware, spyware, and unauthorized third-party apps frequently attempt to record or capture user screens to steal sensitive credentials. PLocker eliminates this vulnerability entirely with programmatically enforced, always-on screenshot and screen sharing/recording protection. Across the entire application—whether you are viewing your password list, generating a key, reading a secure note, or updating settings—screenshot attempts are blocked by the operating system, and any attempts to cast, record, or share your screen will result in a blacked-out window. This non-configurable security feature ensures that your passwords remain invisible to remote snooping or unauthorized local capture.

Programmatically blocked screenshots across all screens
Screen sharing and casting blacked out automatically
Always-on, non-configurable security for absolute safety
Protects against local snooping and screen-scraping malware

Protected Screens. Zero Visual Leakage.

Privacy by Design, Not by Policy

PLocker doesn't rely on a privacy policy to protect your data—it's architecturally impossible for the app to share anything because it has no internet access. Most password managers collect telemetry and store your vault on their servers; PLocker eliminates those risks entirely by design.

Full Features, Zero Cost

While other password managers lock essential features behind paid subscriptions—password generation limits, vault size caps, or advanced security options—PLocker gives you every feature, completely free. No premium tiers, no feature paywalls, no subscriptions ever.

You Are Not the Product

Free password managers often monetize through data collection, analytics, or selling anonymized usage patterns. PLocker collects absolutely nothing. No crash reports, no usage statistics, no feature analytics. What you do inside your vault is known only to you.
