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.

UMA CARTA DO NOSSO FUNDADOR
Estamos construindo Cyra de forma transparente.
Cyra tem zero usuárias hoje. Quero ser honesto sobre isso antes que você leia qualquer outra coisa neste site.
Sou o Christian. Tenho 23 anos. Estou construindo Cyra de Kigali, Ruanda, porque as mulheres com quem cresci — minha mãe, minhas irmãs, minhas amigas — durante anos cada app de menstruação disse que seus ciclos eram 'irregulares.' O que isso realmente significava: os apps foram feitos para outra pessoa, e fingiam que ela era o padrão.
Cyra está sendo construído para os 80%+ das mulheres cujos ciclos não seguem o manual de 28 dias. Usamos aprendizado de máquina real que aprende O SEU padrão. Você pode enviar fotos dos seus registros antigos de menstruação para que o app construa seu modelo preditivo desde o primeiro dia, mesmo que você nunca tenha rastreado digitalmente. E seus dados ficam no seu celular, a menos que você escolha de outra forma. Cyra também é construída para que nenhuma mulher fique de fora: login por impressão digital ou Face ID, chat de voz para falar com Cyra em vez de digitar, e suporte completo a leitores de tela — porque mulheres com deficiência foram ignoradas por quase todos os apps de menstruação, e isso termina aqui.
Se você é uma mulher que foi silenciosamente informada pela tecnologia que seu corpo está errado — Cyra é para você. Ainda não chegamos lá. Estamos construindo. Obrigado por chegar cedo.
