Beta v1.0.0 · September 10, 2026

About Lantern
Lantern is made by Celestia Diagnostics, Inc., doing business as Celestia Life Sciences. It is a wellness app that helps people with chronic conditions track symptoms and treatments and understand how their condition changes over time.
Lantern is not a medical device and does not provide medical advice. Nothing in the app is a treatment recommendation or substitute for advice from a healthcare professional.
Lantern is still being developed, so features may change, stop working, or be removed, and data could be lost. Do not use Lantern as your only record of important information.
Lantern is available only to adults in the United States.
Information we collect
- Account information, such as your name, email address, date of birth, sex at birth, race, and state or territory.
- Health information you enter, such as conditions, symptom ratings, and treatment records.
- Usage information and feedback that help us operate and improve Lantern.
Lantern does not request access to your device's location or track your activity outside the app.
How we use your information
We use your information to provide and improve Lantern, communicate with you about the service, and learn from de-identified or aggregated information.
We may de-identify or aggregate information across users to analyze patterns, evaluate, and improve Lantern.
We may analyze, report, or publish findings based on de-identified or aggregated information. We will protect the privacy and confidentiality of individual users and will not report or publish information that identifies them.
How we share and protect your information
We do not sell or license data collected through Lantern, including identifiable, de-identified, or aggregated data.
We do not use your health information for advertising or targeted marketing or share it with advertisers, data brokers, or information resellers.
We may share information with service providers that help us operate Lantern, when required by law, or when reasonably necessary to protect Lantern, our users, or the rights and safety of others. We require service providers to use information only as necessary to provide their services and to protect it consistent with this agreement and applicable law.
We use administrative and technical safeguards designed to protect your information. No system can guarantee absolute security.
Your choices and data retention
Connecting a supported health-data source is optional, and you can revoke access at any time to stop future collection from that source.
You can delete your account within the Lantern app or contact us at lantern.support@celestialifesci.com. Depending on where you live, you may also have rights to access, correct, delete, or limit certain uses of your information.
We retain identifiable information while your account is active and as reasonably necessary to operate Lantern. When you delete your account, we remove identifying information from our active systems, except for limited records needed for legal, security, or operational purposes. Information already de-identified or aggregated may be retained and used as described above.
If our data practices materially change, we will update our disclosures and obtain additional consent where required.
Legal terms
We do not guarantee that Lantern will always be available, accurate, uninterrupted, or error-free. This agreement is governed by the laws of Delaware.
