Own your health—and your data
Developed by leading reproductive health researchers, privacy experts, and users like you, Euki empowers you to learn about your body and take control of your health.
Euki takes privacy seriously. The app will never ask you for identifying information and doesn’t collect any of your health data—it’s all stored locally on your phone. Only YOU have access to it.
As a free app run by a nonprofit staff, donations from our community make it possible to expand Euki's functionality and meet evolving user needs. Your support helps us get period tracking tools and critical reproductive health resources to those who need them most—protecting user privacy every step of the way.
Ibis Reproductive Health—a nonprofit organization that seeks to advance sexual and reproductive autonomy, choices, and health worldwide—supports the research and management of Euki. Funds donated to Ibis through this site will directly support app maintenance and updates. If you'd like your contribution to go toward all of Ibis's work, please donate here.
