What is my IP address and what does it reveal? +
Your IP address is a unique identifier assigned by your ISP to your internet connection. It can reveal your approximate city, region, and country, as well as your internet service provider. It does not reveal your exact home address or personal identity.
How do I know if I'm using a VPN? +
A VPN replaces your real IP with a server IP — often flagged as belonging to a datacenter or known VPN provider. Our VPN check compares your IP's ASN against known VPN/proxy ranges. For a full test, visit our
VPN detector page.
What is screen resolution and why does it matter? +
Screen resolution is the number of pixels your display shows horizontally × vertically (e.g. 1920×1080). Higher resolution means sharper text and images. It matters for web design, gaming, video quality, and accessibility settings.
What is a user agent string? +
A user agent is a text string your browser sends to every website you visit. It contains information about your browser name, version, operating system, and rendering engine. Websites use it to serve compatible content and for analytics.
Is this information stored or logged? +
No. All detection on this page runs entirely in your browser using JavaScript APIs. No data is sent to our servers. The only external requests are to
ip-api.com for IP geolocation, which has its own privacy policy. See our
Privacy page for details.
How is screen size in inches calculated? +
We use your screen's pixel resolution and the browser's devicePixelRatio to estimate physical dimensions. The diagonal in inches is calculated using the Pythagorean theorem on width and height in physical pixels, divided by the display's DPI. This is an estimate — actual size may vary slightly by device.
