Could you build this?
Partial The cycle tracker, predictions, and UI are straightforward to vibe-code. End-to-end encrypted sync, partner sharing, and health-data privacy obligations need security and compliance expertise that is easy to get wrong.
What it would actually take: Build a local-first mobile app with an on-device encrypted store and a sync layer that encrypts client-side before upload, so the server only sees ciphertext. Key exchange for partner sharing needs a vetted protocol and key-recovery design. Prediction logic is simple, but presenting it as honest ranges and meeting GDPR/health-data rules requires someone who has audited encryption and privacy design before.
