Frequently Asked Questions
Everything you need to know about privacy, accuracy, and how the analysis works
Minhas fotos são armazenadas ou salvas?
Não. As imagens são processadas inteiramente na memória e excluídas imediatamente após a análise. Nunca armazenamos ou salvamos suas fotos.
Quão precisa é a análise?
A IA usa MediaPipe Pose Landmarker para detectar 33 pontos corporais com alta precisão. As métricas são calculadas a partir desses pontos. Os resultados dependem da qualidade da foto, iluminação e consistência entre as fotos.
Que tipo de fotos funcionam melhor?
Fotos de corpo inteiro com boa iluminação, roupas mínimas e pose consistente entre as fotos de antes e depois dão os resultados mais precisos. Fotos de frente funcionam melhor.
Isso é realmente grátis?
Sim, completamente grátis. O site é mantido por anúncios para que possamos mantê-lo acessível a todos.
What metrics does the AI measure?
The AI detects 33 body landmarks and computes: V-taper ratio (shoulder-to-waist), waist change, shoulder width change, arm fullness change, waist-to-height ratio, and shoulder-to-height ratio. Each metric is shown as a percentage change.
Do I need an account to use the tools?
No. All calculators, the AI trainer, and the body analysis tool work without an account. A free account is only needed if you want to sync your workout and measurement data across devices.
Can I use this on my phone?
Yes, the site is fully responsive and works on mobile phones and tablets. Photos taken with your phone camera work well as long as lighting and pose are consistent.
What is the AI Fitness Trainer?
The AI Fitness Trainer is a free chatbot that runs entirely in your browser using WebAssembly. It answers questions about workouts, nutrition, body composition, and using our tools. Nothing you type leaves your device.
