PRIVACY NOTICE
Version: v2026-01-24
Effective from February 1, 2026
1 Introduction
Your Twin, LLC (“we," "us," or "our") offers Lyona mobile application and the Lyona website (together, the “Services” or “Lyona”). Lyona is a software application that provides digital coaching and health- and wellness-related information through a text- and voice/video-based chatbot.
This Privacy Notice explains how Your Twin, LLC collects, uses, discloses, and protects your personal information (“Personal Information”), which is information that is directly linked or can be linked to you. It applies to Personal Information that Your Twin, LLC processes when you access or use our Services, including the Lyona mobile application and website (collectively, the "Services").
By registering for an account, accessing, visiting, and/or using the Services, you agree to the terms of this Privacy Notice and our Terms and Conditions of Service (hyperlink). If you do not agree, you must discontinue use of the Services immediately.
2 When This Privacy Policy Applies
This Privacy Policy applies whenever you (“User”) register for an account or otherwise accessing, visiting, and/or using our Services. It does not apply to services that have separate privacy policies that do not incorporate this Privacy Notice, like Third-Party Services and Third-Party Links.
Third-Party Services. “Third-Party Services” means any third-party software, application programming interfaces (APIs), tools, data sources, artificial intelligence technologies and large language models, payment processors, products, websites, or other services that are relied upon by, integrated with, or made available through the Services.
Third-Party Services may require the transmission or processing of certain Inputs and Personal Information by third-party providers in accordance with their applicable terms, privacy policies, and data-processing practices and for purposes related to the provision and operation of such Third-Party Services.
Third-Party Links and External Resources. When you use links or references to websites, content, or resources operated by third parties (“Third-Party Links”) within our Services, the privacy policies of these third parties apply to any Personal Information you provide or consent to share with them. Their privacy statements will govern how this data is processed. We are not responsible for the information practices of such third parties.
3 Information We Collect and How
The information we collect depends on how you interact with us (for example, through our website or mobile applications), the Services you use (you may use only the website, Lyona application or both) and the choices you make (such as the information you choose to provide in the chatbot).
We collect information about you from multiple sources and in several ways, including information you provide directly, information collected automatically, and information we infer or generate from other data.
Information You Provide To Us:
Account Information. When you create an account, we collect information such as your display name, email address, password, and time zone. We may also generate indirect identifiers associated with your account.
Payment Information. For paid subscriptions, we collect billing-related information such as your name, billing address, and payment details.
User Content and Files (Inputs and Outputs). When you use our Services, we may collect the information you provide into the Services via Inputs. Inputs represent content you choose to provide to the Services, including by submitting photos, videos, text, data, or other information. If your Inputs contain personal information or reference external content that information will be collected. We may also store chatbot responses (“Outputs”) to provide continuity, personalization, and context across sessions, such as remembering your preferences, goals, and prior interactions so you do not need to repeat information.
Demographic and health information. We may collect demographic or body-related information that you choose to provide through chatbot—such as age, gender, height, weight or similar details—to enable specific features of the Services. We may also collect wellness-related information provided by you, such as mental state, sleep habits, exercise activity, or food intake, to support personalized nutritional coaching. To learn about collection, use and disclosure of Consumer Health Data, please visit the Consumer Health Data Privacy Notice (hyperlink).
Feedback Information. We collect information you submit through surveys, reviews, interactive features, interviews, or beta testing related to your use of the Services.
Communication information: If you contact us directly, we collect your name, contact information and the content of the communications.
Sensitive Personal Information. Some of the information above may be classified as Sensitive Personal Information under applicable law. This may include account access credentials, demographic information, and wellness- or health-related information you voluntarily provide, as well as certain information we infer to better support you.
We may collect Sensitive Personal Information that you choose to share. Our chatbot processes and stores the content of your conversations, including any Sensitive Personal Information related to health that you voluntarily provide.
We use Sensitive Personal Information solely to provide personalized wellness and nutritional guidance, maintain continuity in your coaching experience, tailor the Services to your individual needs, and secure and operate the Services.
Please do not share information you do not wish to be collected or used as part of your interaction with the Services.
Not HIPAA-Regulated Services. Your Twin, LLC and Lyona are not a “covered entity” or “business associate” as those terms are defined under the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”).
Information you provide through the Services, including health- or wellness-related information, is not considered protected health information (PHI) under HIPAA and is not subject to HIPAA’s privacy or security requirements.
While HIPAA does not apply, we take the privacy and security of your Personal Information, including Sensitive Personal Information, seriously and handle it in accordance with this Privacy Notice and applicable state privacy laws.
Please do not submit information through the Services that you would only feel comfortable sharing with a HIPAA-covered healthcare provider, unless you understand and agree that such information will not be protected by HIPAA when provided to us.
Information We Create or Generate
We may generate or infer new information from other data we collect from you to better understand your preferences or characteristics (“Inferences”). For example, we may infer your body mass index (BMI) based on the height and weight information you provide in order to deliver the Services.
Information We Collect Automatically
Device Information and Connection Specific Information. We might collect information such as but not limited to browser type, operating system, IP address, device identifiers, time zone, the date and time of access to provide and secure the Services.
Service Usage Information. We might collect information about how you use the Services, including access times, feature usage, and interactions within the chatbot (such as links you click), to improve the quality and functionality of the Services.
Log and Troubleshooting Information. We might collect log files and diagnostic information related to Service performance. If an error occurs, we may collect information about the error, the time it occurred, the feature being used, the state of the application, and any content or communications associated with the error.
