# Developer Ecosystem & Ethical Design

Jessie OS is designed to be composable, permissionless, and privacy-forward:

* **DevKit SDK**: Build and monetize custom AI modules — from niche skills (e.g. ADHD support) to industry-specific coaches (e.g. startup founders)
* **API Integration Layer**: Jessie can interface with wearable data, calendar apps, DeFi wallets, and productivity tools
* **Ethical AI Compliance**:
  * Opt-in local storage for user preferences
  * Zero-knowledge proofs for sensitive interactions
  * Transparent model architecture for third-party audits

Jessie doesn’t just respect privacy — it’s built on it.
