Embody

Embody is a period- and cycle-tracking app built around a privacy-by-default model, storing a user’s health data locally on their own device rather than on a company server by default. Launched in March 2023 by Anna Hall, a former educator, and incubated by the product studio Thesis, Embody was created directly in response to the U.S. Supreme Court overturning the constitutional right to abortion in 2022, a shift that raised concerns about menstrual-tracking data being used as evidence in criminal investigations in states that restrict abortion.

Why period-tracking privacy became a concern

Period-tracking apps collect some of the most sensitive data a person can generate about their own body, including dates of menstruation, sexual activity, and pregnancy symptoms. After the end of the constitutional right to abortion, journalists, lawmakers and privacy advocates warned that this data, if stored on a company’s servers, could be obtained through a subpoena or law-enforcement request and used to investigate someone suspected of ending a pregnancy, even in states where that act is not itself illegal to discuss.

How Embody’s privacy model works

Embody describes its approach as a tiered model: data is stored locally on the user’s own phone by default rather than uploaded automatically, the app does not offer an opt-in “anonymous mode” because privacy is the default rather than a setting to switch on, and a paid membership tier adds optional end-to-end encrypted cloud backup for people who want their data to survive a lost or broken phone. Because Embody does not hold a readable copy of a user’s encrypted backup password, the company says it cannot recover that password if the user forgets it, a tradeoff that keeps even Embody itself from reading backed-up data.

Embody as a Thesis-incubated product

Embody was developed inside Thesis, a studio that builds and launches its own consumer products rather than taking on outside client work, giving the app resources and technical support beyond what a typical early-stage startup might have at launch. The company has described itself as led by a team of women, positioning Embody within a broader wave of “femtech” products built specifically around women’s health needs and, in Embody’s case, a particular emphasis on data they control rather than data a company collects by default.

How Embody compares to mainstream period trackers

Most widely used period-tracking apps, including some of the largest on the market, have historically stored user data on their own servers to power features like cycle predictions, syncing across devices, and personalized insights, which also means that data exists somewhere a court order could potentially reach. Embody’s local-first design trades away some of that convenience, such as instant multi-device syncing without a paid plan, in exchange for keeping sensitive health data off a server by default.

Embody and the broader femtech privacy movement

Embody is part of a wider wave of “femtech” products, apps and devices built specifically around women’s health, that has grown to include fertility trackers, menopause-support apps and maternal-health platforms. Within that category, a smaller group of apps, including Embody, has specifically positioned data privacy as its core differentiator rather than a secondary feature, responding to a climate in which reproductive-health data has become unusually politically and legally sensitive in parts of the United States. This has made privacy-first design a competitive advantage rather than a niche concern for apps serving users in states with abortion restrictions.
