About mylune

mylune is a cycle and health companion app developed by Byteren Inc. It is designed to help you track your menstrual cycle, log daily health data, and build awareness of your own patterns over time.

mylune is not a medical device. It is not certified by the FDA, CE, or any other medical regulatory body. It does not diagnose, treat, cure, or prevent any medical condition. Cycle predictions are statistical estimates based on your logged history - they are not clinical measurements and should not be used as the basis for medical decisions.

These terms apply to all users of the mylune app and website, including users in the United States, India, and all other territories where the app is available.

The Privacy Architecture

mylune is built on an on-device architecture. All health data you enter in the app - including cycle dates, symptoms, moods, sleep, nutrition, and private notes - is stored only on your device. It is never uploaded to any server, never transmitted to Byteren Inc., and never shared with third parties.

This architecture is described in detail in our Privacy Policy at mylune.com/privacy-policy. By using mylune, you acknowledge that the privacy protections you receive come from this architectural design, and that Byteren Inc. is structurally unable to access, recover, or provide your health data to any party, including law enforcement, absent physical access to your unlocked device.
