What Is This

Our powerful natural-language engine uses NASA data, coupled with the methods of professional astrologers, to algorithmically generate insights about who you are and how you relate to others.

Access to astrology this accurate has historically been restricted to those with access to personal astrologers—now these predictions can be anyone's.

Astrology puts our temporary bodies in context with our universe's vastness, allowing irrationality to invade our techno-rationalist ways of living.

Star Speak Astrology proprietary technology couples insightful humans with data from NASA’s Jet Propulsion Laboratory and cutting-edge natural language-AI to give people personalized context for their lives.
We use your date, time, and place of birth to use astrology to generate the content that powers your astrology experience.
We choose which transits to surface on your home screen based on your past behavior within the app. For example, if you always look at your 6th/10th house or Saturn transits, we assume that’s because you’re a workaholic and show you more of those transits – and sometimes show you less because you should go outside more. 😉
We do not use or have access to any third party data, including but not limited to your texts, your mic, or other trackers. We don’t track your activity or usage on any other app or any other website.
We do use Google Analytics (same as 89% of other top websites) to see how people interact with the app, such as what they click on and how many screens or pages they visit and if the app crashes, so we can fix bugs and make the app better.
