Reproductive Data Privacy Laws in Washington (2026)

Subpoena: A court order compelling a person or company to produce documents or data. Period tracker apps that store data on their servers can be served with subpoenas — apps that store data only on your device cannot.

Reproductive data: Health information related to menstrual cycles, pregnancy, fertility, and related symptoms. This data is not protected by HIPAA when held by period tracker apps, meaning standard federal health privacy law does not apply.

On-device storage: A privacy architecture where all personal data is stored exclusively on the user device and never transmitted to a company server. Because there is no server record, law enforcement subpoenas have nothing to retrieve.

Abortion Law Status in Washington

Abortion access is constitutionally protected in Washington. The state codified abortion rights in the Reproductive Privacy Act (RCW 9.02.100) in 1991, providing one of the longest-standing statutory protections for abortion in the country. Washington has consistently defended and expanded reproductive rights, and the state’s legal framework for abortion access was well established long before the Dobbs decision changed the federal landscape.

Period Tracker Data Risk in Washington

Period tracker data in Washington faces low subpoena risk given strong legal protections. Washington’s My Health MY Data Act (2023, effective March 2024) is the most targeted health data privacy law in the country for period tracking apps, explicitly covering reproductive health data and requiring affirmative consent before it can be collected or shared. The state’s shield law (SB 5489) protects technology companies based in Washington from out-of-state subpoenas related to abortion. Washington’s combination of constitutional abortion protection, specialized health data law, and a strong shield law makes it the best state in the country for period tracker users.
