Coverage

Samples by environment

Each environment is evaluated independently. Rankings stay hidden until that environment reaches the minimum display sample.

EnvironmentQualified samplesPublication status
Desktop832Distribution available

Legacy tablet samples are excluded because the first classifier could mistake touch-enabled desktop computers for tablets.

Clear dimension anomalies are excluded from rankings but remain in aggregate storage for auditing.

Methodology

How to read this report

The report describes this site's measured browser sessions, not global device or browser market share.

Collection and privacy

A browser tab contributes at most one sample during its session. Measurements are rounded into monthly aggregate buckets. No IP addresses, user IDs, precise timestamps or full user-agent strings are stored. Global Privacy Control and Do Not Track signals are honored.

Quality and limitations

Viewports wider than 6,000 CSS pixels or taller than 4,000 are excluded from published distributions. Historical DPR values are normalized to 0.05 steps. Device class is inferred locally and remains an approximation; legacy tablet classifications are excluded.
