Storage & Cookie Manager is a browser extension that helps you view, edit, and manage LocalStorage, SessionStorage, and Cookies for the active browser tab. Your privacy is important — this extension is designed to work entirely locally on your device.
We do not collect, store, transmit, or share any user data. Specifically:
- ❌ No analytics or tracking
- ❌ No data sent to external servers
- ❌ No personal information collected
- ❌ No cookies set by the extension itself
- ❌ No third-party services or SDKs
This extension requests the following permissions, each with a specific purpose:
| Permission | Why It's Needed |
|---|---|
activeTab |
To access the storage data of the currently active tab when you open the popup. |
scripting |
To inject a script into the active tab that reads/writes LocalStorage and SessionStorage. |
cookies |
To read, create, edit, and delete cookies for the current site via the Chrome Cookies API. |
storage |
To save your last-used tab preference (Local/Session/Cookies) locally within the extension. |
<all_urls> |
Required by the Cookies API to access cookies across all websites you visit. |
- All storage and cookie data is read directly from your browser and displayed in the extension popup.
- Edits are written directly back to the browser via standard browser APIs.
- Exported JSON files are saved locally to your device via the browser's download mechanism.
- Your tab preference is stored in
chrome.storage.local— this data never leaves your browser.
The only data this extension persists is your last selected tab (Local, Session, or Cookies), stored via chrome.storage.local. This is a browser-local API and the data stays on your device.
This extension does not communicate with any third-party services, APIs, or servers. It has zero network activity.
This extension is fully open source. You can audit the complete source code at: https://github.com/cyberzilla/StorageManager
