Important Notes

Accuracy: File downloads are tracked accurately through Chrome’s download system.

Estimations: General browsing traffic and some page activity are estimated. This is because Chrome does not expose exact network throughput for every site in the same way it exposes download manager data.

Privacy

SpeedMeter Overlay works locally in your browser.

It is designed purely to monitor performance and does not collect personal browsing data.

Settings are stored locally and may sync through Chrome sync storage if enabled in your browser.
