Your Browser Data, Fully Under Control

Reloadium Data Manager gives you a clear window into everything your browser is storing on your device. From localStorage keys to IndexedDB records, cookies to service worker caches — it's all visible and manageable in one place.

Whether you're debugging a web app, auditing your privacy, or just curious what's accumulating in your browser, Data Manager makes it easy to find, inspect, copy, and delete any piece of stored data.

Key Features

Local & Session Storage

Browse all localStorage and sessionStorage keys with their values and byte sizes. Search, copy, delete individual entries, or clear everything at once.

Cookie Inspector

View all cookies set for this origin. See name, value, and path — and delete any cookie directly from the interface.

IndexedDB Explorer

Drill into every IndexedDB database, expand object stores, and inspect individual records. Delete records, clear stores, or drop entire databases.

Cache Storage Viewer

List all service worker caches and the URLs they contain. Delete individual cached responses or wipe an entire cache bucket.

Storage Quota Dashboard

See a real-time bar showing how much of your browser's storage quota is in use — with color-coded warnings as you approach the limit.

Cross-Store Search

Filter entries by key or value within any tab. Instantly find the data you're looking for across thousands of stored items.

How It Works

1

Open Data Manager

Navigate to the Data Manager app. It loads instantly with no sign-in required — all data is read directly from your browser.
2

Pick a Storage Type

Switch between tabs: Local Storage, Session Storage, Cookies, IndexedDB, or Cache Storage. Each tab loads its data automatically.
3

Inspect & Search

Use the search bar to filter entries by key or value. Click into IndexedDB databases to drill down to individual object store records.
4

Delete What You Don't Need

Click the trash icon next to any entry to remove it, or use 'Delete all' to clear an entire store. A confirmation dialog prevents accidental deletions.

Perfect For

Web App Debugging

Quickly inspect what your app is persisting — check auth tokens, cached API responses, user preferences, and IndexedDB state without opening DevTools.

Privacy Audit

See exactly what data other sites and apps have stored in your browser. Delete anything you're not comfortable keeping.

Storage Cleanup

Free up space by dropping unused IndexedDB databases, clearing old caches, and removing stale localStorage entries from apps you no longer use.

Developer Testing

Reset app state between test runs by clearing specific stores or cookies — faster than opening DevTools and navigating to Application → Storage.

Frequently Asked Questions

Does Data Manager access data from other websites?

No. Browsers sandbox storage by origin. Data Manager can only see data stored by the Reloadium domain — it cannot access localStorage or cookies from other websites.

Can I accidentally delete important data?

Every destructive action (delete item, clear store, drop database) requires confirmation via a dialog. You always have a chance to cancel before anything is removed.

Why can't I see data from other Reloadium apps?

All Reloadium apps share the same origin (reloadium.com), so their localStorage, IndexedDB databases, and cookies are all visible here in one place.

What is Cache Storage?

Cache Storage is used by service workers to store network responses for offline use. Clearing it won't delete your app data — it only removes cached assets that will be re-downloaded on next use.

Is Session Storage different from Local Storage?

Yes. Session Storage is cleared automatically when you close the browser tab. Local Storage persists until you explicitly delete it. Data Manager shows both separately.

Do I need to sign in to use Data Manager?

No. Data Manager works fully without an account. Signing in only enables the credit balance display in the header.
