P3A.md

Privacy Preserving Product Analytics Metrics

This is a human-readable list of product analytics metrics collected. The list of metrics collected can also be found in the source code. The analytics reported are not exact numbers, but are collected into aggregate "buckets" or histograms. The process for this aggregation can also be verified in the source code.

General information about P3A can be found on our support page.

Encoding Parameters

Metric reports encoded using the STAR protocol use an aggregation threshold of 50 for each layer.

Submission of STAR-encoded reports is controlled by the BraveP3AConstellation feature flag added in 1.52 and enabled by default in 1.62. Parallel submission of metrics without STAR is suppressed by the BraveP3ATypicalJSONDeprecation feature flag for weekly-cadence questions and BraveP3AOtherJSONDeprecation for others, added in 1.62.

Current Metrics
