Questions & answers
How do I use Network speed test?
Start a speed test to transfer synthetic data and measure current download, upload and latency.
What limits should I know about?
The test uses real bandwidth. Wi-Fi, VPNs, concurrent downloads and server routes affect this measurement.
Where do my files and data go?
Fingerprints are computed locally. Speed tests send synthetic data; address checks contact STUN and public-IP services. Your media files are not uploaded.
