Privacy-first period tracking
Menstruation is political.Your data should not be.
Circles is a local-first period tracking app built for autonomy, inclusion, and collective care. Track what you need, share what matters, and keep your intimate health data under your control.
Local first
Track symptoms, phase, and wellbeing offline, and keep full control over your history.
E2E sharing
Share selected insights with trusted people through end-to-end encrypted channels.
Why Circles
Built against surveillance,built for real care.
Most period apps are not neutral. They can extract more data than needed and monetize deeply personal information. We reject that model: bodies and cycles are not commodities.
My body is not your data.
Period leaks are normal. Data leaks should not be.
Share what matters. Keep what is yours.
Menstruation is political. Care is collective.
Track your daily reality
Capture mood, physical symptoms, phase changes, and what support you need in under a minute.
See patterns without being profiled
Understand trends like energy or stress resistance over time without feeding surveillance capitalism.
Coordinate care in your circle
Invite roommates, partners, and chosen family to receive only the updates you intentionally share.
Collective care
Menstruation is not binary, care is not normative, and autonomy is non-negotiable.
Circles supports feminist, queer, and trans-informed care practices by giving you explicit control over visibility and sharing at every step.
Take back your cycle data.
Period tracking should never become a witch hunt. Join the Circles waitlist and help shape a safer, more inclusive future for menstrual health.
