Position accuracy and fix age
Compare the reported uncertainty radius and the age of each fix. Nothing is sent or stored.
Fix controls
No coordinates.
Interpretation
Age is calculated from the browser’s fix timestamp, not the button tap. On a real phone, walk only where safe. Compare movement with accuracy before treating a change as meaningful.
Worked captures use emulated location in mobile Chromium. A real phone’s fixes and cache behaviour vary. Do not publish coordinates.
Limit: two fixes and an accuracy radius do not prove a travelled route or exact position.
