Zero-Knowledge Architecture

Privacy Policy

Last Updated: February 21, 2026

Your Data is Yours. Period.

Ousia was built as a digital sanctuary to liberate you from the noise of the world. We believe true peace requires absolute privacy. Therefore, Ousia operates on a strict "Zero-Knowledge" architecture.

1. Data We Do Not Collect

All AI generation is performed locally on your device using a secure, on-device Large Language Model. Your private thoughts never touch a cloud server.

2. Data We Do Collect (Strictly for Functionality)

3. Third-Party Integrations

Ousia generates contextual search queries for companion apps (like Spotify or YouTube). These queries are generated locally on your device and handed off to those respective apps. Once you leave Ousia, you are subject to the privacy policies of those third-party services.
