Guided walkthrough
Guided walkthrough
Understand what the local-data inspector can display.
- Only run the inspection intentionally. It can display this site’s storage key names and JavaScript-readable cookie values.
- Read the explanation before running the tool yourself. This walkthrough does not load an example or start an inspection.
Illustrative example
A fictitious storage key such as demo_theme illustrates a name only. This walkthrough does not read, populate, or clear storage or cookies.
How to read the result
The scope is this website, not every site or the whole device. HttpOnly cookies are not visible to JavaScript. Cookie values may contain credentials; do not copy or share the report without removing sensitive data.
This is a static educational walkthrough. It does not fill fields, generate values, inspect your browser, or read storage. Use fictitious, non-secret data for practice. Never share passwords, keys, tokens, or cookie values. These explanations are not a security audit or certification.

Quick answer
List local and session storage key names and show JavaScript-readable cookie name/value pairs for this site’s origin in the current browser. Review cookie values before sharing the result.
The page and its assets load from the site; this operation uses your entered values only in this browser and does not send them to a calculation endpoint.
How to use it
Inspect local storage, session storage, and JavaScript-readable cookies for this website only. It cannot inspect data belonging to other websites or browser extensions.
Limits
This page can read storage exposed to this site’s origin only. It cannot inspect other sites’ storage or extension data.
Frequently asked questions
Can it inspect storage from other websites?
No. Browser origin rules limit this page to data exposed to this site’s origin. It cannot inspect another site or extension storage.
What does the result reveal?
It lists local and session storage key names, not their stored values. Readable cookies appear as name=value pairs, so they can include sensitive session credentials; review before sharing. Cookies marked HttpOnly are not exposed to JavaScript and are omitted.
What is the difference between local and session storage?
Both are origin-scoped browser storage. Local storage persists across browser sessions; session storage is generally scoped to a tab’s page session.
