Your Data

Overview

Your data is private.

Period.

We do not sell data. Never have, never will. Our business is built on subscriptions, not your personal information.

We take your privacy seriously and protect your personal data by anonymizing and encrypting it.

Our encryption method ensures your health data is stored securely and separately from your real-world identity. By partnering with Rownd, an authentication platform, we are able to store your contact information externally, while your health data is tied only to a random account ID.

We also work hand-in-hand with a legal team specializing in privacy, technology, and data security and have passed Apple and Google’s rigorous privacy and data safety reviews. You can learn more in the Privacy/Data Safety sections of the App Store and Google Play.

Transparency is one of our core values. We’ll be ruthlessly candid, even when it’s hard, and we’ll keep raising the bar on privacy and security. We’re not just people working at a company—we’re people who use Stardust ourselves. Protecting your reproductive health data isn’t just business for us. It’s personal.
