Euki
Makers of Euki App, the Privacy-First Period Tracker. Expanding access to reproductive health + defending digital privacy.
Euki is the privacy first period tracker - plus so much more.
About Euki
Euki is a tech-nonprofit working at the intersection of Reproductive Health and Digital Privacy to promote agency and autonomy over our collective sexual and reproductive health data, decisions and care.
Euki co-designs with users who face specific barriers and/or risks to accessing reproductive health care- because when tech meets the needs of those who face the most barriers, everyone benefits.
The Euki App
Our flagship product, the Euki App, is a no-cost mobile period tracker that also connects users to research based information on censored or stigmatized sexual and reproductive health experiences including Abortion, Contraception, Menstruation, and Sexuality- all without collecting one single bit of their data.
Since launching in 2019 on iOS and Android, Euki App has been:
- Downloaded and trusted more than 215,000 times
- Hailed as “a critical resource,” “more than a period tracker,” and “one of the best, most empowering apps I’ve used” in uncompensated app store reviews
- Recognized by privacy experts at the Mozilla Foundation and Vagina Privacy Network
Your support helps expand access to reproductive health care and information while defending digital privacy.
Thank you.
