Locker: Quick Start & Transparency#

Set up Locker in less than 2 minutes and learn exactly why the extension requests certain permissions. No marketing language, just an honest explanation from the developer.

Step 1. Pin the Extension#

Click the Puzzle icon 🧩 in Chrome, find Locker, and click the Pin 📌 icon so it is always easy to access.

Step 2. Enable Incognito Mode#

Open the extension details page and enable Allow in Incognito.

This allows Locker to work with private browsing sessions while keeping your data encrypted.

Step 3. Create Your Master Password#

Your Master Password is stored only on your device.

I cannot see it, recover it, or send it anywhere because it never leaves your computer.

If you forget your Master Password, your encrypted data may become inaccessible unless Cloud Sync was enabled beforehand.

Step 4. Configure Hotkeys#

Chrome requires keyboard shortcuts to be configured manually.

Open chrome://extensions/shortcuts and assign the shortcuts you want.

Transparency#

People often ask why Locker requests several permissions. That’s a fair question.

Here is exactly what each permission is used for.

Debugger & Scripting

These permissions are used exclusively for the Web to PDF feature. When you click Save as PDF, Locker temporarily captures the page exactly as it appears in your browser so it can generate a clean, high quality PDF. The debugger is not used to monitor your browsing activity and only runs while creating the PDF.

Access to all hosts

Locker can save bookmarks or generate PDFs from virtually any website, including YouTube, Medium, GitHub, localhost, and other pages you visit.

Chrome requires host permissions before an extension can access the current page.

Without this permission, Locker would only work on a small number of websites.

Tabs & Tab Groups

These permissions power the Tab Manager feature.

Locker can save your currently opened tabs as organized groups, close them to free memory, and restore everything later.

Everything is stored locally unless you explicitly enable Cloud Sync.

Identity

This permission is used only for secure authentication with Google OAuth.

It allows you to sign in and synchronize your encrypted data across your own devices if you choose to enable Cloud Sync.

Downloads

This permission lets Locker save generated PDFs directly to your computer.

It is also required when exporting your bookmarks as HTML or JSON so you always have full control over your own data.
