# This Period-Tracking App Actually Keeps Your Data Private
Period-tracking apps have become targets for privacy concerns, especially after the Supreme Court's Dobbs decision on abortion rights. Parents and teens need tools that genuinely protect sensitive reproductive health information instead of selling it to advertisers or exposing it to government requests.
Euki offers a different approach. The app stores all data locally on your phone, meaning your period information never leaves your device. You don't need to create an account, so no email or personal details get collected. This architecture prevents the app from selling data to third parties, a common practice among popular trackers like Flo and Clue.
Local data storage matters for teens especially. If a young person uses a period tracker, that health data stays on their phone where only they can access it. No cloud servers. No company accounts. No paper trail that could surface in unexpected places.
Euki still functions as a tracker should. You log periods, track symptoms, and get predictions for upcoming cycles. The app just refuses to weaponize that information for profit or surveillance.
Parents considering period trackers for teenage children should ask specific questions: Where does the app store data? Do you need an account? What's the privacy policy actually say? Does the company sell data? Euki answers those questions cleanly: phone storage, no account required, local-only, no sales.
The broader context matters here. Many free period apps generate revenue by selling user data to pharmaceutical companies, fertility clinics, or advertising networks. Users often don't realize their menstrual cycles are commodified. After Dobbs, privacy advocates raised fresh concerns about reproductive data being used against people in states with abortion restrictions.
This doesn't mean Euki is the only privacy-respecting option, but it represents a deliberate choice to center user control over profit. For parents helping teens navigate digital health tools
