Permissions & privacy.

Everything below is what any website could ask about or see when you visit — permission states, notification and clipboard access, cookie handling, the referrer you send, Do Not Track, and the surface a fingerprinter can measure. All checks run locally in your browser. Nothing here is sent anywhere.

Permissions inventory

Every permission name the browser recognises, with its current state. "Prompt" means the browser will ask when a site tries to use it.

Notification test

Whether this browser will show system notifications, and how it responds to a request. Nothing is scheduled — a test notification only fires if you click below.

Notification.permission

Clipboard read / write

Modern browsers restrict clipboard access without a user gesture. These buttons probe both directions and show what the browser reports.

clipboard-write
clipboard-read

Cookie & storage access

How this browser handles cookies, particularly across sites. Third-party cookies are being phased out; browsers are moving to partitioned storage instead.

Referrer & referrer policy

What this browser tells the sites you visit about where you came from. Each row shows what the Referer header would carry under a specific policy — computed locally, no requests made.

document.referrer
Active page policy

Do Not Track & Global Privacy Control

Two signals your browser can send that ask sites not to track you. In practice: DNT is widely ignored; GPC is legally recognised in a growing list of jurisdictions.

navigator.doNotTrack
navigator.globalPrivacyControl
Sec-GPC HTTP header

Fingerprinting surface

Values a fingerprinter can read passively to identify a returning visitor. Individually harmless; combined, they're often unique. This is a summary, not a full fingerprint.

What Test Your Rig itself asks for

Nothing. This site requests no permissions, no notifications, no clipboard, no geolocation. The only storage used is a small local cookie for your theme and language preferences, and if you sign in, a first-party session cookie. Every benchmark, test and tool runs entirely in your browser. See the privacy policy for the legal detail.
