Every partner deserves to understand what she's going through

Relationships don't have a default language. PinkyBond works in 71 languages so every partner — whether in Tokyo, Berlin, Mumbai, or Mexico City — can understand what she's experiencing. The app adapts to your language, your context, and your relationship.

Every message, check-in and call is end-to-end encrypted between her phone and yours with Curve25519 key agreement and AES-256-GCM — Apple CryptoKit on iPhone, Google Tink on Android. She pairs with you by QR code in person or a short code from afar. No phone number, no email, no account. Our relay forwards ciphertext it cannot open. She chooses what you see and can pause any time.

Every partner guide in PinkyBond is built on the same peer-reviewed medical research that powers PinkyBloom. When we tell you what she might be feeling during the luteal phase or her third trimester, it's backed by ACOG, WHO, NIH, and published clinical studies. We cite every source because understanding starts with truth.

PinkyBond doesn't work alone. It connects to PinkyBloom — her period tracker and AI companion — through an encrypted bridge that she initiates and controls. Together, they create a health communication channel that has never existed before: she gets AI-powered insights, and you get the context to be the partner she needs.
