Is my data safe when using the Open Graph预览?

Does the Open Graph预览 work offline?
After the page loads for the first time, the Open Graph预览 works without an internet connection for all client-side processing. Tools that fetch live external data (such as DNS or network lookups) require an active connection.
How current is the data returned by the Open Graph预览?
The Open Graph预览 fetches live data in real time each time you run it. Results reflect the current state of the server or domain at the moment of the request.
Why does the Open Graph预览 sometimes return different results than other tools?
Results depend on the real-time state of the target server and DNS propagation, which can vary by geographic region and caching TTL. If you see inconsistencies, wait a few minutes and re-test — DNS changes can take up to 48 hours to propagate fully worldwide.
Does the Open Graph预览 work on all browsers?
Yes. The Open Graph预览 is built with standard browser APIs and works on all modern browsers including Chrome, Firefox, Safari, and Edge — on both desktop and mobile. No plugins, extensions, or third-party software are required.
How do I save or export my results from the Open Graph预览?
