Can your period tracker data be subpoenaed?

Only data stored on a company server can be subpoenaed. If your period tracker syncs to the cloud, that data can be requested by a court or law enforcement. If it stays on your device, as it does with mylune, there is nothing for anyone to subpoena. Here is how the difference works.

Cloud versus on-device: where your data actually lives

A subpoena is a legal order to produce records. It can only reach records that exist. When a period app stores your cycle history in the cloud, a copy of that data sits on the company's servers, and that copy can be requested through legal process, obtained in a data breach, or shared with third parties under the app's policies.

When an app keeps everything on your device, there is no company-held copy. mylune has no user database and no server that stores health data, so there is nothing on our side for a court to compel us to produce. This is a structural difference, not a promise we could quietly reverse.

What changed for period data in the US

Since 2022, cycle tracking data has been part of a wider conversation about reproductive privacy in the United States. In states where reproductive care carries legal risk, people have grown more cautious about where their period history is stored and who could request it. Privacy advocates and security researchers have repeatedly pointed to cloud-stored health data as the exposure point.

The most reliable protection is simple: if the data never leaves your phone, there is no server copy to request. That is the principle mylune is built on.

Period tracker privacy and legal questions

Can police or courts access my mylune data?

No. Because mylune stores nothing on any server, there is nothing to subpoena. Courts cannot compel us to hand over data we do not have. Your data is on your phone, protected by device encryption.

Is mylune safe to use in US states with abortion restrictions?

Yes. Because mylune stores nothing on a server, there is nothing a court can subpoena from us. This is architecture, not policy. You can also enable Legal Protection Mode for additional safeguards including clinical terminology and conservative auto-deletion.

Can my period app data be subpoenaed?

Only if it exists on a server. If your period app stores data in the cloud, that data can be obtained via subpoena or court order. mylune stores everything on your device only - there is nothing on our infrastructure to compel us to produce.

What is Legal Protection Mode?

Legal Protection Mode is a setting designed for women in US states where reproductive health data carries legal risk. When enabled, it uses clinical terminology in all stored records and applies conservative data auto-deletion defaults.

How do I hide mylune on my phone?

Enable Stealth Mode in Settings. The app icon changes to a calculator or utility icon. The app name changes in your recent apps list. No health-related words appear in notifications. All your data stays intact.
