MenstruationPeriodRecord: Health Connect menstruation data

Read from Google’s documentation on 2026-10-03 · Google’s reference page last updated 2026-06-24

MenstruationPeriodRecord is Health Connect's menstruation record — an Interval record in Google's Cycle Tracking category. Its read permission is android.permission.health.READ_MENSTRUATION; its write permission is android.permission.health.WRITE_MENSTRUATION. Google's reference defines no aggregate metrics on it, so it is read with readRecords rather than aggregate. Mandatory fields per Google's table: endTime, metadata and startTime.

The 5 fields of MenstruationPeriodRecord

Types and descriptions as Google’s reference prints them. The range column quotes Google’s own range annotation or sentence; a dash means Google states none, which is not the same as no validation.

HealthKit counterpart

No verified HealthKit counterpart. The cross-platform matrix only pairs metrics checked against both Apple’s and Google’s documentation, and MenstruationPeriodRecord is not among them yet. A similarly named Apple type may exist on the HealthKit reference, but a name match is not a verified mapping.

The metric on other platforms

This guide lists MenstruationPeriodRecord beside the types on the other platforms this site covers whose own descriptions name the same metric, each quoted, with how each one is read.

Questions

What permission does MenstruationPeriodRecord need?
Google's Health Connect data-types table (read 2026-10-03) declares android.permission.health.READ_MENSTRUATION for reading MenstruationPeriodRecord and android.permission.health.WRITE_MENSTRUATION for writing it, and says apps must declare permissions in the manifest before requesting them. READ_MENSTRUATION and WRITE_MENSTRUATION are also declared for MenstruationFlowRecord.
Can you aggregate MenstruationPeriodRecord with AggregateRequest?
Not directly. As read on 2026-10-03, Google's Jetpack reference defines no AggregateMetric constants on MenstruationPeriodRecord, so there is no metric to put in an AggregateRequest. Read the records with readRecords and a ReadRecordsRequest, and compute any summary yourself.
Is MenstruationPeriodRecord an interval, instantaneous or series record?
Google's data-types table lists MenstruationPeriodRecord as Interval, and defines that column as indicating "whether the data is recorded at an instant in time or over an interval". Its mandatory fields are endTime, metadata and startTime.
