Period Tracker Data Risk in Colorado

Period tracker data in Colorado faces low subpoena risk. The Colorado Privacy Act gives residents rights over their personal data. HB 23-1058 specifically covers consumer health data and requires affirmative consent before it can be collected or shared. Because abortion is protected and the state has strong health data laws, period tracker users in Colorado face among the lowest risks in the country.

Federal Protection Status

The HIPAA Reproductive Privacy Rule (which would have prohibited disclosure of protected health information for investigating lawful reproductive healthcare) was vacated nationwide on June 18, 2025 by a federal court in Texas. HHS declined to appeal. Biden-era executive orders directing FTC and HHS action on reproductive data privacy were revoked on January 24, 2025. A ClearDATA/Harris Poll survey (May 2023, n=2,053) found 81% of Americans wrongly believe HIPAA covers health apps. It does not. Period tracker apps are not healthcare providers and fall entirely outside HIPAA regardless of state. There is no federal floor for reproductive health data protection.

Key facts

State: Colorado
Abortion law: protected
Data protection: strong
Subpoena risk: low

Colorado has no gestational limit on abortion access, making it one of the most permissive states.
The Colorado Privacy Act provides a legal basis for consumers to delete personal data held by period tracking apps.
HB 23-1058 specifically requires affirmative consent before collecting or sharing consumer health data.
Colorado does not prosecute abortion-related cases, so state-level subpoena risk is minimal.

Definitions

Subpoena: A court order that can require a person or company to produce documents or data. Period tracker apps that store readable data on their servers can receive subpoenas. Local-first apps reduce what the company can produce.
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 core cycle records stay local-first. Optional encrypted sync may send unreadable ciphertext. Because there is no readable central cycle database, company-directed requests should have less core cycle data to retrieve. Device access and operational records are separate risks.

HB 23-1058 requires companies to get your explicit consent before collecting or sharing health data. This includes reproductive health information from period tracking apps.

Can another state subpoena my period tracker data through a Colorado company?

No. HIPAA does not apply to consumer apps. Colorado's state laws pick up where federal law leaves off.
