Locker: Quick Start & Transparency

How to set up the extension in 2 minutes and why it requests these permissions. An honest conversation from developer to user.

Step 1: Pin It

To keep Locker handy: click the "Puzzle" icon 🧩 in the top-right corner of Chrome, find Locker, and click the "Pin" icon 📌.

Step 2: Incognito Mode

By default, Google blocks extensions in private mode. To let Locker save bookmarks in Incognito, enable it: Right-click the icon -> "Manage Extension" -> Toggle "Allow in Incognito".

Step 3: Master Password

On first launch, you will be asked to create a password. IMPORTANT: It is stored strictly locally on your device. The developer does not have access to it and does not store it.

If you forget this password, your data may be lost. Recovery is possible only if Cloud Sync was enabled, and requires reinstalling the extension!

Step 4: Hotkeys

Chrome doesn't let extensions set shortcuts automatically. To open Locker instantly (e.g., Alt+B), go to chrome://extensions/shortcuts and set a combo that works for you.

Transparency: Why so many permissions?

A human-friendly explanation of why every feature is needed.

Debugger & Scripting

Sounds scary, but it's needed for one goal: Web to PDF. When you click "Save", the extension needs to "photograph" the article exactly as you see it to create a clean PDF. The debugger runs ONLY to generate high-quality PDFs.

Access to all hosts

So you can download a PDF or save a bookmark from ANY site (be it YouTube, Medium, or localhost), the extension needs the right to "read" that site. Without this, Locker cannot save the content.

Tabs & TabGroups

The "Tab Manager" feature allows you to save open tabs as groups LOCALLY on your device and clear the browser. This helps free up RAM and saves your session context!

Identity

Used for authorization and the cloud. This is needed for secure login via Google (OAuth).

Downloads

Needed strictly so you can: 1) Save generated PDFs to your disk; 2) Export all your bookmarks to HTML/JSON if you decide to stop using Locker.
