Privacy Policy

1. About This Policy

At ODYSS, we believe that privacy is a fundamental right — and that this fundamental right should not differ depending on where you live in the world. This policy explains how we collect, use, disclose, and protect information related to you when you use our AI-powered necklace ("Device"), mobile app ("App"), and website at odyss.life ("Website") (collectively, the "Services").
Our services involve dietary and health data — among the most sensitive categories of information we handle. We take that responsibility seriously. This document is our way of being transparent about what we do, especially when it comes to camera images and AI processing.
OdyssLife.Inc. ("ODYSS," "we," "us," or "our") is the entity behind this policy.
This policy uses a layered consent approach:
  • Basic service notice: By using our services, you acknowledge the general data practices described here.
  • Separate consent for sensitive data: For health data collection, voice data processing, cloud-based food image analysis, and other sensitive operations, we will seek your explicit opt-in consent when you first use the relevant feature. You may withdraw consent at any time.

2. Information We Collect

Information You Provide

When you sign up for and use our services, you provide us with certain information:
  • Account details: Name, email, phone number, date of birth, gender, height, weight, and dietary preferences you enter when signing up.
  • Health profile: Dietary goals, allergies, health conditions, and nutrition targets you choose to share. This information is used solely to provide the personalized services you've selected.
  • Payment information: Credit card details and billing address for purchases. We don't store full card numbers — payment processing is handled by professional providers.
  • Communications: Customer support inquiries, survey responses, and feedback.

Information Collected by the Device

The ODYSS device collects the following information as it works to provide you with its services:
  • Food images: During meals, the device camera captures images of food and beverages. When the camera is activated, it captures real-time footage that may include non-food scenes — but we do not record video, conduct surveillance, or analyze faces and bodies. Images are briefly stored on the device and uploaded via standard encryption to our cloud servers for AI recognition and nutritional analysis. Before processing, images are screened to ensure only food-related content proceeds to the next step. Original images are automatically deleted after AI processing is complete, with no long-term retention. You can also manually delete your original images at any time. See Section 4 for details.
  • Usage patterns: Meal timing, eating frequency, and tracking session duration.
  • Device data: Battery level, connection status, firmware version, and device health indicators.

Voice Data

Voice data involves biometric and health-related information and is a highly sensitive data category, so we describe it separately:
  • You can submit audio or voice recordings to log meals, interact with AI features, or use voice-related functions.
  • Voice data is collected only when you actively trigger it — we never record continuously in the background.
  • The use of voice data requires your explicit opt-in authorization. You can manage voice permissions or withdraw consent at any time in Settings.
  • We currently do not collect, store, or process voiceprints or voice biometric data. If we ever involve such processing, we will seek your separate written consent and disclose retention periods.
  • Voice data retention period is duration of account + 30 days, automatically deleted after account deletion. You can also manually delete it at any time.

Information Collected by the App and Website

When you use our App or visit our Website, we automatically collect certain technical and usage information:
  • App usage data: Features used, pages visited, session duration, and interaction patterns.
  • Device and technical data: IP address, device type, operating system, app version, browser type, language, time zone, mobile network information, and unique device identifiers.
  • Location data: Approximate location derived from IP address (country/region level). With your authorization, more precise location may be obtained from your mobile device for device connection, Bluetooth-related features, regional settings, or security purposes — for example, Bluetooth pairing requires location access to discover nearby devices.
  • Cookies and tracking technologies: See our Cookie Policy for details on how we use cookies and similar technologies on our website.

Third-Party Services

If you choose to connect third-party services, we may receive information from them, including:
  • Apple Health / HealthKit, Google Health Connect, Google Fit, or similar health platforms;
  • Apple, Google, or other supported login services;
  • Payment processors, analytics providers, customer service tools, or cloud service providers.
We only collect information from third parties within the scope you've authorized and only as necessary for the relevant features — for example, we only access health data from Apple Health after you've connected it and explicitly selected the data categories you want to share. We do not use HealthKit data or health data obtained through other health platforms for advertising, marketing, or other usage-based data mining purposes.

Health and Dietary Data

When you use our services, we collect and process health-related data, including:
  • Nutritional data: Calorie estimates, macronutrient breakdowns (such as protein, carbohydrates, fat, and fiber), micronutrient estimates, and meal composition generated by AI analysis of captured food images.
  • Dietary patterns: Eating habits, meal regularity, dietary trends, and long-term nutritional balance insights.
  • Health insights: Personalized nutrition recommendations, dietary observations, and progress toward your health goals.
We classify this data as sensitive personal information and provide it with the enhanced protections described in Section 7.

3. How We Use Information

We use the information we collect to provide and improve our services, to communicate with you, and to maintain safety and compliance.
Provide and improve services
We use your information to identify and analyze food captured by the device camera, generate nutritional estimates and dietary insights, create personalized nutrition recommendations and reports, sync data between your device, app, and account, and provide customer support and respond to your inquiries.
Improve AI technology
We use aggregated and de-identified data only to enhance food recognition algorithm accuracy, develop new features, and enhance existing services. We also study dietary patterns using anonymized datasets — these datasets cannot be traced to any individual.
Communicate with you
We may send you service-related notifications (such as sync status or device updates). With your consent, we may also send marketing messages, and you can withdraw this consent at any time. We also use your information to answer your questions and requests.
Maintain safety and compliance
We use information to detect and prevent fraud, abuse, or security issues, to comply with legal obligations, and to enforce our terms of service.

4. Camera and Image Data

A wearable device with a camera naturally raises reasonable questions about privacy. We believe you have the right to know exactly what the camera captures, what it doesn't, and how image data is handled.

What the Camera Captures

The camera activates only when an eating or drinking moment is detected, or when you manually trigger a food capture. It captures still images of food and beverages. Please note:
  • When the camera is activated, it captures real-time footage that may include non-food scenes — but we do not record video, conduct surveillance, or analyze faces and bodies.
  • The camera does not record conversations or audio.
  • The camera does not function as a surveillance device.
  • The camera does not activate outside of meal tracking contexts.

How Images Are Processed

Our image processing follows a brief on-device storage + cloud-based AI analysis approach:
  1. On-device capture: The device camera captures food images, which are briefly stored on the device.
  2. Encrypted upload: Images are transmitted via standard encryption to our cloud servers. Upon upload, the server performs initial screening to identify and filter out faces and non-food environments, ensuring only food-related images proceed to the next step.
  3. Cloud AI analysis: Food recognition and nutritional analysis are performed in the cloud, extracting nutritional data (such as calories and macronutrients).
  4. Automatic deletion: Original images are automatically deleted after AI processing is complete, with no long-term retention. Extracted nutritional data is synced to your app.
  5. User control: You can manually delete your original images at any time through the app.
After a meal ends, the device may continue uploading and processing captured images in the background. You can check the upload and processing status in the app, or interrupt transmission at any time by enabling Privacy Mode.
Regarding data access: Without your permission, no ODYSS personnel can access your uploaded raw data. Data remains encrypted throughout server storage and processing.

About AI Training

By default, we do not use your food photos to train general-purpose AI models. If we ever want to use user data for model training or optimization (including food photos, voice recordings, or other user content), we will seek your separate, explicit consent first. You can decline without affecting any core feature. Data from Apple Health and other health platforms is never used for model training — now or in the future.

Privacy Mode

We understand that you may want to disable the camera entirely at times. The device includes a Privacy Mode that you can activate at any time with one tap via the device button or the app. Privacy Mode status is confirmed through three independent signals: (1) device LED indicator, (2) vibration feedback, and (3) app status display. When Privacy Mode is active, no images are captured or processed.

5. Device Permissions

To function properly, the app may request access to certain device permissions. You can manage these at any time in your device settings. Specific permissions are based on the actual requests initiated by the app; the following are key examples:
  • Camera & Photo Library: Capturing meal images, scanning QR codes, uploading avatars, or using image-based features
  • Microphone: Submitting audio or voice input to log meals, interact with AI features, or use voice-related functions. The microphone works only when you actively trigger it — we never record continuously in the background.
  • Location: When necessary for device connection, Bluetooth settings, regional services, or security — for example, Bluetooth pairing requires location access to discover nearby devices
  • Bluetooth: Searching, pairing, connecting, and syncing with the wearable device
  • Notifications: Sending reminders, tips, progress updates, and device-related notifications
  • Health data: When connecting to Apple Health/HealthKit or similar services, only data categories you explicitly authorize for specific features are accessed

6. AI Features

Some service features use artificial intelligence, machine learning, or automated processing to analyze information you provide or that is generated through the service. AI features can help identify food, estimate nutrition, summarize behavioral patterns, or generate personalized health recommendations.
To be clear: AI-generated content is intended for general health management and informational purposes only. It does not constitute medical advice, diagnosis, or treatment, and should not replace professional medical judgment. We recommend consulting a licensed healthcare professional before making any major health-related decisions. We also clearly label AI content as non-medical in nature within the App interface.
Regarding AI model optimization, our position is:
  • By default, we do not use your food photos, voice recordings, or other user content to train general-purpose AI models.
  • If we ever want to use such content for model optimization or algorithm improvement, we will seek your separate, explicit consent beforehand.
  • You can decline or later withdraw this consent without affecting core features.
  • We do not use Apple Health/HealthKit data or health data obtained through other health platforms for AI model training.
  • If we use third-party AI providers to process your content for features you've requested, those providers may only process it on our behalf for that specific function and are contractually, technically, and legally restricted — they cannot use it to train general-purpose AI models.

7. Health Data Protection

Your dietary and health data is sensitive personal information. This section provides you with additional protections under applicable health data privacy laws, including the Washington My Health My Data Act (MHMD), Connecticut Data Privacy Act, Nevada Revised Statutes, and similar state-level health data privacy laws.

9. No Sale of Personal Information

We do not sell personal information in exchange for money.

However, we may share certain personal information with advertising and marketing partners through cookies, pixels, software development kits, and similar technologies for cross-context behavioral advertising, as that term is defined under the California Consumer Privacy Act (“CCPA”).

In the preceding 12 months, the categories of personal information that we may have shared for cross-context behavioral advertising include:

• Identifiers, such as IP address, cookie identifiers, device identifiers, and advertising identifiers;
• Internet or other electronic network activity, such as pages viewed, links selected, referring pages, and interactions with our Website;
• Commercial information, such as products viewed, cart activity, purchases, and transaction-related events; and
• Inferences relating to interests or advertising audiences that may be created from Website activity.

These categories may be shared with advertising networks and marketing technology providers, including Meta and, where applicable, Google.

We do not sell or share health data, dietary data, food images, voice recordings, HealthKit data, or other personal information collected through the ODYSS Device or App for cross-context behavioral advertising.

California consumers may opt out of the sale or sharing of their personal information by selecting “Your Privacy Choices” in the Website footer. An account is not required to submit an opt-out request.

We also process legally recognized opt-out preference signals, including Global Privacy Control (“GPC”), as a request to opt out of sale or sharing for the browser or device through which the signal is sent.

After receiving an opt-out request, we will stop sale or sharing associated with that browser, device, or known consumer as required by applicable law. We will not ask the consumer to opt back in for at least 12 months, unless otherwise permitted by law.

11. Data Security

We implement industry-standard measures to protect your information. All data is encrypted in transit using TLS 1.3 and at rest using AES-256. Employee access to personal data is limited to those with a legitimate business need, and all access is logged and audited.
Our systems are designed from the ground up to minimize data exposure — the device captures food-related images, which are briefly stored on-device and uploaded via encryption to our cloud servers. The server screens for faces and non-food content before processing, and original images are automatically deleted after AI analysis, with only extracted nutritional data retained. Without your permission, no ODYSS personnel can access your uploaded raw data.
We conduct regular security audits and penetration testing, and we maintain an incident response plan. In the event of a data breach, we will notify affected users within the shortest time period required by applicable law and without unreasonable delay, and will comply with all applicable state data breach notification laws.
No system is completely secure. We recommend using a strong password and enabling two-factor authentication to further protect your account.

12. Your Rights

At ODYSS, we respect your ability to know, access, correct, delete, and export your personal data in a machine-readable format, as well as to opt out of marketing communications. We have provided these rights to our global user base, and if you choose to exercise these privacy rights, you have the right not to be treated in a discriminatory way.

California Residents (CCPA/CPRA) additionally have the right to:

  • Know what personal information is collected and how it's used
  • Request deletion of your personal information
  • Opt out of the sale of personal information (we don't sell data to begin with)
