Frequently Asked Questions
Why is my screen resolution different from viewport size?
Screen resolution is the total number of physical pixels on your monitor. Viewport size is the actual space available for the web page, which is smaller due to browser address bars and toolbars.
Is my device data stored?
No. All diagnostics are read dynamically in your browser memory and never saved to a database.
