Our Services may contain links to third-party websites. Once you leave our Services, we do not control how your data is handled by those sites. We encourage you to review their privacy policies before using their services.

By using our Services, you acknowledge and accept the terms of this Privacy Policy. If you do not agree, please discontinue use immediately. We may update this policy from time to time, and any changes will be posted on this page. Your continued use of the Services after any update constitutes acceptance of the revised policy.

1. Data We Collect from You

At Milieu, we are committed to delivering exceptional products while safeguarding your privacy. We only collect the data necessary to enhance your experience and provide our Services effectively. The specific types of data we collect depend on how you interact with us and our products.

When you create a Milieu account, make a purchase, visit our website, communicate with our chatbot, contact our support team, respond to our surveys, or engage with us in any other way, we may collect both Personal Information (“Personal Information”) and Sensitive Personal Information (“Sensitive Personal Information”) (collectively, “Collected Information”), including:

Personal Information

Account and Contact Information. Information provided through your Milieu Account and related account details, including full name, email address, date of birth, phone number, and postal address.
Lifestyle Information. Your living habits, such as skin care routines, current skincare products used, sleep habits, exercise habits, sun exposure, water intake, diet, and makeup usage.
Location Information. Your zip code, home address, and other location data help us analyze your environment but do not constitute precise geolocation data.
User Behavior. Information about how you interact with our website, including pages visited, time spent on pages, navigation patterns, click activity, and other engagement metrics. This data may be collected through cookies, tracking technologies, or analytics tools to improve user experience and website functionality.
Other Personal Information You Provide to Us. We may collect any other personal information you choose to provide when you communicate with us, including through customer support, surveys, feedback, social media interactions, or other means.

Sensitive Personal Information

Health Information. Information related to an individual's health status, conditions, treatments, or medical history, such as skin condition (general or seasonal), skin concerns, age, sex assigned at birth, stress level, menstrual cycle, and other relevant conditions.
Biomaterials. Your skin swab samples collected through the testing kit. The material will be analyzed to assess your skin microbiome. At no point during our services will your genetic materials be sequenced, analyzed, or digitized.
Personal Image. Any personal photos or images uploaded to our website.

2. Usage of Collected Data

Your collected data will never be sold, exchanged, transferred, or shared with any other company without your consent, except as outlined in this Privacy Policy.

Specifically, we do not use Collected Information for any purposes other than the following:

to tailor the features, performance, and support of our Services to you and your preferences such as formulating customized skin care products and providing personalized health insights and recommendations;
to verify your identity as the holder of an account with us;
to manage orders, respond to inquiries, provide assistance, and address any questions or concerns related to our Services;
to market our Services that we believe may be of interest to you.
to provide, operate, analyze usage of, and improve our Services, including research and development;
to comply with legal obligations, including responding to court orders, government, or regulatory requests;
to ensure security, detect and prevent fraud, and address security incidents, abusive behavior, or suspected malicious or illegal activities; and
to enforce our Terms of Service, policies, and agreements with you and third parties.

3. Data Security

We take the security of your data seriously. We have implemented measures designed to secure your Collected Information from accidental loss and from unauthorized access, use, alteration, and disclosure. Collected Information is encrypted and securely transmitted to protect your privacy. After transactions, Collected Information is stored in an encrypted third-party database that complies with industry security standards.

The safety and security of your information also depends on you. Where we have given you, or where you have chosen, a password to access certain parts of our Services, you are responsible for keeping this password confidential. We ask you not to share your password with anyone. We urge you to be careful about giving out information in public areas of the Website like customer review message boards. The information you share in public areas may be viewed by any user of the Website.

Although we do our best to protect your Collected Information, the transmission of information via the internet is not completely secure, and we cannot guarantee the security of your Collected Information transmitted to our Services. Any transmission of Collected Information is at your own risk. By using our services, you acknowledge and accept these inherent risks. We are not responsible for circumvention of any privacy settings or security measures contained on our Services. We encourage you to take precautions when handling Collected Information, particularly when using public computers or unsecured networks, to further safeguard your data.

4. Data Retention

We retain Collected Information for as long as necessary to provide our Services, fulfill your requested transactions, comply with legal obligations, resolve disputes, enforce agreements, and support other legitimate business purposes. Retention periods are determined based on the nature of the data, applicable legal requirements, and business needs.

For example, if you provide Personal Information when creating an account, we may retain it for as long as your account remains active. Sensitive Personal Information will only be retained for the minimum period required to fulfill the original purpose of collection, comply with legal obligations, or as explicitly permitted by law. Identifiable biomaterials will be retained for no longer than 24 months, or until a valid request for deletion or destruction is received, whichever occurs first, unless a longer retention period is legally required.

If Collected Information is no longer necessary for our Services or required by law, we will delete or de-identify it in accordance with our data de-identification guidelines outlined in Section 5 of this Privacy Policy. However, we may retain certain Personal Information if necessary to comply with legal, accounting, or regulatory obligations.

If you reside in a jurisdiction that grants specific privacy rights, please refer to the Your Privacy Rights section below for details on how to exercise those rights.

5. Data De-Identification

We may de-identify personal information to ensure that it cannot reasonably be linked to an individual or household. When we de-identify data, we implement technical and administrative measures to prevent re-identification. Additionally, we do not re-identify any de-identified data and require any third parties who receive such data to adhere to contractual obligations prohibiting re-identification.

Because de-identified data does not contain personally identifiable information, we may retain it for a longer period than identifiable data, and it is not subject to our data retention guidelines outlined in Section 4 of this Privacy Policy. We may use de-identified or aggregated data for research, analytics, and other lawful purposes.

We may use de-identified data to conduct internal research, support product development, and advance technological innovation, including the development and refinement of AI algorithms and machine learning models for both existing and new applications. This may involve using data to enhance functionality, optimize performance, and drive innovation within our Services, with our affiliated partners, or through new ventures.

For this policy, “de-identified” data refers to data that has been de-identified, aggregated, or anonymized, using methods required or permitted by the applicable state law.

6. Disclosure of Your Information

Other than as described herein, we do not sell, trade, or otherwise transfer to third parties your Collected Information.

We may disclose Collected Information:

to contractors, service providers, and other third parties we use to support our business and who are bound by contractual obligations to keep your information confidential and use it only for the purpose for which we disclose it to them;
to a buyer or other successor in the event of a merger, divestiture, restructuring, reorganization, dissolution, or other sale or transfer of some or all of Milieu's assets, whether as a going concern or as part of bankruptcy, liquidation, or similar proceeding, in which personal information held by Milieu about our Website and Services users is among the assets transferred;
to fulfill the purpose for which you provide it;
for any other purpose disclosed by us when you provide the information;
to our subsidiaries and affiliates; or
with your consent.

IT service providers, including cloud storage, hosting, and cybersecurity vendors;
analytics and marketing partners to help us improve and promote our Service;
logistics and fulfillment partners for order processing and delivery;

to enforce or apply our Terms of Service and other agreements, including for billing and collection purposes; or
when we believe disclosure is necessary or appropriate to protect the rights, property, or safety of Milieu, our customers, or others.

We may disclose aggregated information about our users, and de-identified information, without restriction.

7. Your Privacy Rights

We are committed to protecting your privacy and ensuring compliance with applicable federal and state laws, such as California Consumer Privacy Act (CCPA) as amended by California Privacy Rights Act (CPRA).

If you are a resident of California, or a state with similar privacy laws, you may have the following rights regarding your personally identifiable data. These rights do not apply to data that has been de-identified.

Right to Limit Use of Sensitive Data. For sensitive data we collect (e.g., biometric information), you may restrict its use to only what is necessary for providing our Service.

However, we respect user privacy and provide alternative options to manage tracking preferences through cookie settings.
