Maryland Online Data Privacy Act (MODPA), sensitive data and biometric consent

cite Md. Code Ann., Com. Law ยงยง 14-4701(d), (gg), 14-4707(a) stage RECENT in force 11 months effective 2025-10-01 reviewed 2026-08-27

MODPA classifies genetic or biometric data, alongside racial or ethnic origin, religious belief, health data, sexuality, transgender or nonbinary status, national origin, citizenship or immigration status, a known child's data, and precise geolocation, as sensitive data.

A controller may not collect, process, or share sensitive data unless strictly necessary to provide a product or service the consumer requested, may never sell sensitive data, and may not process or sell a consumer's personal data for targeted advertising if it knew or should have known the consumer is under 18.

'Biometric data' means data from automatic measurement of a consumer's biological characteristics used to uniquely authenticate identity, including a fingerprint, voiceprint, or eye retina or iris image, and excludes a bare photograph or an audio or video recording, but claws that exclusion back the moment data generated from one is generated to identify a specific consumer.

What it asks of an app

  • Do not collect, process, or share sensitive data, including genetic or biometric data, unless strictly necessary to provide a product or service the consumer requested. MODPA supplies no separate consent-only path around this necessity requirement.
  • Never sell sensitive data. MODPA bans the sale of sensitive data outright.
  • Treat an identifier your product derives from a public photo, video, or audio recording specifically to identify a person as covered biometric data, and therefore sensitive data, even though a bare photograph or recording by itself is excluded. The exclusion does not survive identification-purpose derivation.
  • Do not process a consumer's personal data for targeted advertising, or sell it, if you know or should know the consumer is under 18.
