Privacy Policy

1. Overview

Extension Jetpack ("the Extension", "we", "us") is a browser extension that gives you a fast launcher for managing the other extensions you already have installed in Chrome. From a single popup, opened with the Cmd/Ctrl + J keyboard shortcut, you can search your installed extensions and enable, disable, or open them.

We take the view that the best way to protect your privacy is to never handle your data in the first place. Accordingly, the Extension performs all of its work locally within your browser. This policy explains exactly what the Extension can access, why, and what it deliberately does not do.

2. What data the Extension accesses

The Extension requests a small number of Chrome permissions. Each is listed below in plain language, together with the reason it is needed and where the data goes (in every case: nowhere off your device, unless you personally choose to export a file).

3. What we do NOT do

To be unambiguous, the Extension does none of the following:

• No analytics, telemetry, or usage tracking of any kind.
• No collection of personal or sensitive information.
• No contacting of external or remote servers. The only network activity is loading the Extension's own translation files (_locales/*/messages.json) that ship bundled inside the package.
• No selling, renting, or sharing of any data with third parties.
• No transfer of data away from your device (except a local export file you create yourself).
• No remotely hosted or remotely executed code. All libraries the Extension uses (including Fuse.js and SheetJS/XLSX) are bundled locally and run on your device.
• No advertising, fingerprinting, or profiling.

4. Data storage & retention

All data the Extension touches stays on your device:

• Your installed-extensions list is read live from Chrome each time you open the popup. It is held only in memory while the popup is open and is not persisted by us.
• Your preferences (theme, favorites, last search) are kept in chrome.storage.local until you change them, clear the Extension's storage, or uninstall the Extension. Uninstalling the Extension removes them.
• Brightness readings are transient and are discarded after they are used to choose a theme.
• Export files are created by you, saved by you, and managed entirely by you. We have no copy of them.

Because we never receive your data, there is nothing for us to retain, and no request to delete data needs to be made to us. You can remove everything the Extension stores at any time by uninstalling it.

5. Children's privacy

The Extension is a general-purpose productivity tool and is not directed at children. It does not knowingly collect any information from anyone, including children under the age of 13.

6. Changes to this policy

We may update this Privacy Policy from time to time, for example to reflect changes in the Extension's functionality or in legal requirements. When we do, we will revise the "Last updated" date at the top of this page and publish the updated policy at this same address. Material changes will be reflected here before they take effect.

我們不會：收集個人資料、進行任何分析／追蹤／遙測、連線外部伺服器、出售或分享資料給第三方、載入或執行遠端程式碼。唯一的網路行為是載入擴充功能自身內建的多語系翻譯檔（_locales/*/messages.json）。
