Privacy Policy

Last updated: May 20, 2026

Overview

StoraLens (“the Extension”) is a browser extension that helps developers inspect browser storage. We are committed to protecting your privacy. This policy describes what data the Extension accesses, how it is used, and what we do (and do not) do with it.

Data the Extension Accesses

When you activate the Extension on a page, it reads the following data from the browser APIs on your local device:

  • localStorage and sessionStoragekeys and values for the active tab's origin.
  • Cookiesassociated with the active tab's URL, including metadata such as domain, path, expiry, and security flags.
  • IndexedDBdatabases, object stores, and records belonging to the active tab's origin.
  • The URL and tab ID of the currently active browser tab, used solely to scope storage queries to the correct origin.

How We Use Your Data

All data read by the Extension is processed exclusively on your local device, within your browser. The data is displayed to you inside the Extension popup. It is never:

  • Transmitted to any server or third party.
  • Stored persistently beyond the current browser session.
  • Used for analytics, advertising, or profiling.
  • Shared with the extension developer or anyone else.

Permissions Explained

The Extension requests the following Chrome permissions, each for a specific, minimal purpose:

activeTab

To obtain the URL of the tab you are currently viewing, so storage can be scoped to the correct origin.

scripting

To inject a content script that reads localStorage, sessionStorage, and IndexedDB from the page context. These APIs are only accessible from within the page's JavaScript environment.

cookies

To query the browser's cookie store for cookies associated with the active tab's URL.

Host permissions (<all_urls>)

Because the scripting and cookies APIs require host permissions for each site's origin, and users may inspect any website, broad host access is declared. No data from these sites is ever transmitted off-device.

Export Feature

The Extension includes an optional Export function that lets you download a JSON file of your storage data to your local disk. This file is created entirely on your device. We have no access to exported files and no copy is retained by the Extension.

Third-Party Services

The Extension does not integrate with any third-party analytics, crash reporting, or telemetry services. It makes no outbound network requests of any kind.

Children's Privacy

StoraLens is a developer tool not directed at children under the age of 13. We do not knowingly collect personal information from children.

Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated “Last updated” date. Continued use of the Extension after a change constitutes acceptance of the updated policy.
