Does Stardust sell user data

Stardust states it does not sell user data. We have no evidence of Stardust facing regulatory action for data sharing. However, the privacy claim is policy-based, it depends on Stardust maintaining and honoring its current policy, which can change.

Is Stardust's astrology feature the main differentiator

Yes. Stardust integrates moon phase tracking, astrological sign data, and cycle-astrology correlations. This is the primary product differentiator from standard cycle trackers. The astrology angle appeals to users who want wellness and spiritual context alongside clinical cycle data.

What is the Stardust yearly subscription cost

Stardust Premium is $69.99/yr when billed annually, compared to $95.88/yr ($7.99 x 12) when billed monthly. The annual plan saves about $26.

These are architectural facts that policy language cannot change. A subpoena to Stardust's servers would produce your data regardless of what the privacy policy says. Architectural privacy works differently: if data is stored on your device and never transmitted to a
