Zero-party Data API Provisional Patent + Techincal Whitepaper

The underlying Doppel API technology powers the worlds first, zero-party data token controlled by consumers.

This API is under a provisional patent by Kelly Nyland, Rhenee Bartlett & Ryan Hornberger.

Whym’s shopper identity protocol, Doppel, is designed to offer a new form of online identity that allows users to maintain privacy while still enabling personalized experiences by intentionally creating and sharing their ad or content interests with the world.

Doppel allows for personalization and targeted advertising without the invasive tracking practices that have become commonplace. Whym demonstrates the application of this technology through its user-friendly shopping app and specialized browser concept, suggesting a future where internet users can enjoy a curated online experience without compromising their privacy.
