Download Mouselock – free app to track mouse activity

What Is Mouselock and Why You Might Need It?

Mouselock is a lightweight web‑based tool that lets you know when someone else tries to use your computer while you’re away. The service works by displaying a row of numbered tiles that you turn into a personal PIN, then watching for mouse movement that doesn’t match the expected pattern. If a coworker, housemate, or curious friend attempts to move the cursor, Mouselock flashes the PIN bar, shows a ticking‑bomb graphic, and – if the wrong code is entered – sends you an instant e‑mail alert. While the app is primarily a fun “prank” or awareness gadget, it can also serve as a subtle reminder that your workstation is being accessed without permission. Because it runs entirely in the browser, there’s no need to install heavyweight software, and the interface is designed to be as unobtrusive as possible. The core idea is simple: give you a heads‑up the moment your mouse is taken over, without actually locking the system or encrypting any data. This makes Mouselock a good fit for shared office desks, home PCs in busy households, or any environment where you want to keep an eye on who’s touching your keyboard while you’re grabbing a coffee.

Key Features and How Mouselock Works

Core Functionality

Mouselock’s workflow can be broken down into three easy steps. First, you log in with your Google account – this is required only so the service can send you e‑mail notifications. Second, you choose a numeric PIN by clicking one of the ten numbers displayed across the screen. Finally, you place the mouse cursor in the center of the display and walk away. From that point on, any unexpected mouse movement triggers the alert sequence.

Feature List

• Real‑time e‑mail notifications when the mouse is moved without your PIN.
• Animated “bomb” graphic that adds a playful visual cue for the intruder.
• Optional webcam snapshot (Chrome‑only) that captures the face of the person trying to use the computer.
• Simple Google‑account login – no additional passwords or licences required.
• Cross‑browser support for Chrome, Firefox, and Internet Explorer (basic features).
• Zero‑install, web‑based interface that works on any device with a modern browser.
• Free to use – no hidden fees or subscription models.

While the app does not lock files or encrypt data, the combination of visual alerts and instant e‑mail messages can deter casual snooping and provide a light‑hearted way to catch pranksters in the act. The Chrome‑specific webcam feature adds an extra layer of amusement by sending a snapshot of the “culprit” directly to your inbox, turning a simple alert into a memorable moment.

Step‑by‑Step Installation and Usage Guide

Because Mouselock is a web app, there is no traditional installation process. The entire setup can be completed in under five minutes, even for users who are not technically inclined.

1. Open the Web Portal

Navigate to the official Mouselock website using a supported browser (Chrome provides the full feature set). The landing page will present a clean, centered interface with a row of numbers from 1 to 10.

2. Sign In with Google

Click the “Sign in with Google” button. You will be redirected to Google’s OAuth page where you grant Mouselock permission to send you e‑mail notifications. No personal data is stored beyond what is needed for the alert system, and Google’s privacy policies apply.

3. Choose Your PIN

Select any number from the displayed row to serve as your personal PIN. The chosen number will be highlighted and stored in the session. You can change the PIN at any time by re‑loading the page and repeating this step.

4. Position the Cursor

Move your mouse to the exact center of the screen – a faint crosshair appears to help you align it. Once the cursor is centered, you are ready to step away.

5. Triggering an Alert

If someone moves the mouse, Mouselock flashes the PIN bar, starts the bomb timer, and, after a short delay, sends an e‑mail to the address linked to your Google account. If you have a webcam attached and are using Chrome, a snapshot of the intruder will be attached to that e‑mail.

6. Resetting the Session

After an alert is sent, Mouselock automatically returns to the main page, allowing you to start a new monitoring session without reinstalling anything. Simply repeat steps 3–5 whenever you need to protect your workstation again.

Frequently Asked Questions

Is Mouselock a security tool?

No. Mouselock only notifies you when someone moves the mouse; it does not lock files, encrypt data, or prevent unauthorized access.

Do I need to install anything?

No installation is required. Mouselock runs entirely in the browser, so you just need a compatible web browser and an internet connection.

Can I use Mouselock on a Mac?

Yes. Because it’s web‑based, any Mac with a recent version of Chrome, Firefox, or Safari can access the full feature set (webcam snapshots are Chrome‑only).

Will my Google account be spammed?

Mouselock only uses your Google account to send the alert e‑mail. It does not subscribe you to newsletters or share your address with third parties.

What happens after an alert is sent?

The app returns to the main page, allowing you to set a new PIN and start another monitoring session.
