As Telemetry matures and we add more types of data we want to measure, it is important to keep track of what we're gathering and how we're respecting users' privacy. This page lists all of the types of data collected and links to any risk analysis done for the specific measurements.
The current list of histograms collected is in toolkit/components/telemetry/TelemetryHistograms.h
Instead of full reviews on each major type of measurement, a lightweight risk analysis should be performed to quickly document the question each measurement answers as well as actions taken to minimize privacy risks.
Histograms
Histograms that are collected by telemetry are listed in TelemetryHistograms.h, and ones that have review are also listed in the table below.
Reviewed Data
Data that's being collected and potentially has privacy implications undergoes a quick risk analysis. Data of this type is listed below including any outcomes from the risk analysis.
