Changelog
Version 1.0 foundation: twelve P0 browser diagnostics, privacy-first analytics scaffolding, structured methodology and responsive accessibility.
Our operating principle
Utility, privacy clarity and diagnostic usefulness come first. Every browser measurement is labelled by precision, every sensitive permission follows an explanation, and unsupported capability is never presented as hardware failure.
What the browser can prove
DeviceDoctor reports only what the current browser session can observe. Browser-reported, estimated and user-confirmed results include their limits and a practical next step.
