Privacy Policy

Effective June 26th, 2022

This Privacy Policy explains how Stardust App LLC. ("Company" or "we" or "us") collects, stores, uses, transfers and discloses Personal Data from our users ("you") in connection with the Stardust ® mobile application, stardust.app website ("Website"), and related services (collectively, the "App"). We reserve the right to and may change this Privacy Policy from time to time. If we make any material changes, we will notify you by email (sent to the email address specified when you register), through the App, or by presenting you with a new version of this Privacy Policy for you to accept, if we, for example, add new processing activities or collect some additional Personal Data from you. Your continued use of the App after the effective date of an updated version of the Privacy Policy will indicate your acceptance of the Privacy Policy as modified. In some cases, you will have to explicitly accept changes to Privacy Policy to continue using the App. We encourage you to periodically review our Website and the App for the latest information on our data privacy practices. If you do not accept the terms of the Privacy Policy, we ask that you do not use the App. Please exit the App immediately if you do not agree to the terms of this Privacy Policy.

A special note: Your privacy is of the utmost importance to us. We have implemented an encrypted wall between information identifying you on the one hand (your "PII"), and your health data (menstrual cycle dates, symptoms related to your menstrual cycle, and other information about your health and activities) (your "Health Data," and together with your PII, your "Personal Data") on the other hand, so that your identity cannot be linked to your Health Data. Only you have the unique encryption key and only you can use that key to link your PII and your Health Data.

For example, for the EU residents’ Personal Data we make reasonable efforts to ensure that such third parties are GDPR compliant and have GDPR compliant privacy policies in place.

All data shared at your direction with a third party such as Apple HealthKit is shared in anonymized form and cannot be linked to you.

6. Security

Please understand that this Privacy Policy applies only to information we collect from you. If you are using a third-party link, we will make it clear that such link is to a third party. Where we have linked to a third-party website or service, you should read the privacy policy stated on that third-party website or service.
