PinkyBond vs Selin: Consent-First Context vs Tracking Without Permission

Selin is a period tracker designed for men. You manually enter her cycle dates and Selin gives you predictions and tips. The fundamental problem: it doesn’t require her involvement at all. You can track her cycle without her knowledge or consent.

PinkyBond takes the opposite approach. She initiates sharing from PinkyBloom. She decides what you see. She can pause, modify, or revoke access at any time. PinkyBond is built on consent. Selin is built on observation.

Selin has no encryption and no consent mechanism. A man can create an account, enter estimated dates, and start “tracking” his partner without her knowledge. The data is stored on Selin’s servers in readable form.

PinkyBond cannot function without her participation. The pairing process requires in-person QR code scanning. All data is encrypted with AES-256-GCM. She has Safety Mode to send synthetic data if she feels unsafe. The entire architecture is consent-first.

Selin provides basic calendar predictions based on manually entered dates. No AI insights, no gesture suggestions, no bidirectional sharing, no bridge messages. It’s a calendar with mood predictions.

PinkyBond provides real-time context sourced directly from PinkyBloom, 60+ gesture cards, bridge messages, a cycle education hub, and bidirectional mood sharing. It’s a relationship tool, not a calendar.

If you’re using Selin, we’d encourage you to have a conversation with your partner about PinkyBond instead. Ask her if she’d be willing to share through PinkyBloom. The conversation itself is an act of respect that Selin’s design never required of you.
