Your pain is personal.
But you shouldn't have to carry it alone.

Circles is an inclusive, privacy-first cycle tracking app for everyone. Share your needs in every kind of relationship constellation.

Your body is not our data

You are in control of what you share with whom, at every step of the way. Circles will never see or sell your information.

Period leaks are normal. Data leaks are not.

We minimize data exposure by default and treat your sensitive information with the utmost care. Local-first by design.

Every kind of relationship, welcomed.

Circles was built to accommodate all the different ways people care for one another — partners, friends, chosen family, and beyond.

Care is collective.

Although pain may be personal, it should not have to be carried alone. Mutual support is not a favour — it is part of healthy relationships.

Core Commitments Principles that cannot be negotiated

Why Circles Built against surveillance, and for bodily autonomy while still enabling collective care

Track your daily reality

Capture physical and emotional symptoms, cycle phases, and what support you need from those around you.

Understand your patterns

See trends like energy levels over time and connect your cycle to how you feel day to day.

Coordinate care together

Invite roommates, friends, partners, or chosen family to receive only the information you intentionally share.

Collective Care Tracking together means caring together.

Visibility controls

Set your boundaries with care. Choose exactly what others can and cannot see — down to each symptom, each day.

Emergency-safe defaults

A privacy-first approach keeps your data anonymized and secure by default — no configuration needed.

End-to-end encrypted sharing

What you share travels only between you and the people you choose — never through our servers unencrypted.

Consent-based sharing

Every person in your circle sees only what you've consciously decided to share. Consent is built into the design.

Multiple color themes

Ditch shrink-it-and-pink-it. Circles offers multiple themes that don't assume what pink means to you.

No third-party tracking

No advertisers, no data miners, no surveillance. Your intimate health data is yours — full stop.

When we share our experiences, we make them visible.

We should not be expected to carry all of it alone in a system that does not acknowledge our lived experiences. Help shape the future of menstrual health.
