Every woman deserves to understand her own body
Privately. Accurately. In her own language. On her own terms.
The Truth
Most period apps weren't built for you
80%+
of women don't have a 28-day cycle
Yet almost every period app on the market assumes you do. When your prediction is wrong month after month, it's not your body that's broken — it's the app.
900M+
women track periods on apps that sell their data
Your most intimate health information — when you bleed, when you're fertile, whether you might be pregnant — shouldn't be a product sold to advertisers.
7,000+
languages exist, yet most health apps speak only English
A woman searching for answers about her late period at 2am shouldn't have to translate medical terms from a language she barely reads.
1 in 5
women live with a disability
Most health apps are designed for sighted, hearing, neurotypical users. The rest are told to adapt. We believe the technology should adapt to them.
What We're Building
Cyra is the companion every woman deserves
Not a calculator. Not a calendar. A private, intelligent health companion that learns your unique rhythm.
Real AI, Not Math
Most apps use a simple formula: last period + 28 days. Cyra uses machine learning that studies YOUR history — every early period, every late period, every irregularity. It learns your pattern, not the textbook's.
Your Privacy, Always
100% offline. Data never leaves your phone. No accounts required. No tracking. Biometric lock keeps your information safe. Your body is not a data product.
Every Language, Every Woman
English, Hindi, French, Spanish, Portuguese, Arabic, Kinyarwanda. Health answers in YOUR language — not medical jargon you have to translate at 2am when you're worried.
Designed for Every Ability
Voice input. Screen reader support. High contrast. Large touch targets. Cyra is built so that every woman — regardless of vision, hearing, motor, or cognitive ability — can access her health information with dignity.
For Every Woman
She is why we build
The teenager who has nobody to ask
She got her first period. Her mother doesn't talk about it. Her school doesn't teach it. Her friends repeat myths. She's confused, maybe scared, maybe ashamed. She needs a private, trustworthy, judgment-free companion who speaks her language.
The woman whose app says she's "irregular"
She's been told for years that her cycle is wrong because it doesn't match 28 days. What that really means is the app was built for someone else, and pretended she was the default. She needs technology that learns HER rhythm.
The woman searching for answers at 2am
She's worried. Her period is late. She's searching online in a language that isn't hers, trying to understand medical terms, hoping the answer is "it's normal." She deserves reassurance in her own language.
The woman the tech industry forgot
She has a visual impairment, or a motor disability, or she processes information differently. Most health apps weren't designed with her in mind. She was told to adapt. We believe the technology should adapt to her.

UNA CARTA DE NUESTRO FUNDADOR
Estamos construyendo Cyra de forma transparente.
Cyra tiene cero usuarias hoy. Quiero ser honesto sobre eso antes de que leas cualquier otra cosa en este sitio.
Soy Christian. Tengo 23 años. Estoy construyendo Cyra desde Kigali, Ruanda, porque las mujeres con las que crecí — mi madre, mis hermanas, mis amigas — durante años cada app de período les dijo que sus ciclos eran 'irregulares.' Lo que realmente significaba era: las apps fueron hechas para otra persona, y fingían que ella era la norma.
Cyra se está construyendo para el 80%+ de mujeres cuyos ciclos no siguen el manual de 28 días. Usamos aprendizaje automático real que aprende TU patrón. Puedes subir fotos de tus registros antiguos de período para que la app construya tu modelo predictivo desde el primer día, incluso si nunca has rastreado digitalmente. Y tus datos se quedan en tu teléfono a menos que tú decidas lo contrario. Cyra también está diseñada para que ninguna mujer quede fuera: inicio de sesión con huella o Face ID, chat de voz para hablar con Cyra en lugar de escribir, y compatibilidad total con lectores de pantalla — porque las mujeres con discapacidad han sido ignoradas por casi todas las apps de menstruación, y eso termina aquí.
Si eres una mujer a la que la tecnología le ha dicho en silencio que su cuerpo está mal — Cyra es para ti. Aún no llegamos. Estamos construyendo. Gracias por llegar temprano.
