Privacy Policy

Effective Date: March 13, 2026

Tailored Nutrition LLC ("Tailored Nutrition," "we," "us," or "our") operates the website tailorednutritionllc.org (the "Website") and the Tailored Nutrition mobile application (the "App"). Together, the Website and App are referred to as the "Services."

This Privacy Policy explains how we collect, use, disclose, and protect your personal information when you use our Services. Because our App collects sensitive health-related data to generate personalized nutrition plans, we encourage you to read this policy carefully.

1. Information We Collect

We collect different types of information depending on how you interact with our Services.

1a. Website — Launch Notifications

When you sign up for launch notifications on our Website, we collect:

• Email address — provided voluntarily through our signup form

1b. App — Account Information

When you create an account in our App, we collect:

• Email address — used as your account identifier
• Name — your display name
• Password — stored only in hashed form (we never store or see your plaintext password)

If you sign in using a third-party authentication provider (Google or Apple), we receive your email address and, optionally, your name from that provider. We do not receive or store your Google or Apple password.

1c. App — Health and Body Composition Data

Our App collects detailed health information through an in-depth survey to generate personalized nutrition plans. This includes:

• Demographics — date of birth, biological sex, height, and weight
• Body metrics — calculated values such as BMI and basal metabolic rate (BMR)
• Reproductive health (collected from users who identify as female, at your discretion) — reproductive state (e.g., menstrual cycle tracking, pregnancy week, breastfeeding type, postpartum status, menopause stage), cycle length, cycle regularity, and birth control type
• Activity and training — occupation activity level, lifestyle movement, resistance training details (frequency, duration, intensity, body part focus, volume, progressive overload), cardio activities, and training experience level
• Performance enhancement substances — if voluntarily disclosed, current status (natural, TRT, enhanced cycle, or off-cycle), specific compounds and dosages, cycle duration, and related health considerations
• Health conditions — any medical conditions you choose to disclose (e.g., PCOS, diabetes, hypertension) and their severity
• Medications — names, dosages, frequency, and route of administration for medications you choose to disclose
• Dietary preferences — dietary patterns (e.g., vegetarian, Mediterranean), food allergies, food dislikes, and health-oriented nutrition targets (e.g., increased energy, improved sleep)
• Budget and cooking preferences — meal frequency, weekly grocery budget, cooking skill level, maximum cooking time per meal, and any custom dietary instructions

1d. App — Usage and Tracking Data

As you use the App, we collect:

• Food log entries — meals consumed, nutritional values, dates, and timestamps
• Weight log entries — weight measurements over time
• Meal preferences — meals you have liked, disliked, or requested substitutions for, and the reasons you provide
• Grocery cart data — meals added to your shopping list and custom grocery items
• Chat conversations — messages you send to our in-app nutritional assistant and the responses you receive
• Feedback and feature requests — posts you submit through the in-app feedback system (displayed anonymously to other users)
• Notification preferences — your chosen notification categories and quiet hours

1e. App — Subscription Information

• Subscription status — whether your subscription is active, the source (promotional code, in-app purchase), and expiration date
• Promotional codes — codes you have redeemed

We do not directly collect or store payment card numbers. Payment processing for in-app purchases is handled entirely by Apple (App Store) or Google (Play Store) through their respective payment systems.

2. How We Use Your Information

We use the information we collect for the following purposes:

• Personalized nutrition plans — Your survey responses, health data, and preferences are used to calculate your nutritional targets (calories, macronutrients, micronutrients) and generate AI-powered meal plans tailored to your profile
• Adaptive recommendations — Your food log and weight log data are used to refine your calorie and macronutrient targets over time through our adaptive TDEE (Total Daily Energy Expenditure) system
• Time-sensitive updates — Certain data fields are automatically recalculated when you access your profile, including your age (from date of birth), menstrual cycle phase (from your last period date), pregnancy week, and training progression
• In-app chat assistance — When you use the nutritional assistant, your profile data is provided as context so the assistant can give personalized answers
• Account authentication — Your email and password (or third-party authentication tokens) are used to verify your identity and provide secure access
• Communications — Your email address is used to send password reset codes, launch notifications (if you subscribed on our Website), and service-related communications
• Service improvement — Aggregated, de-identified usage patterns may be used to improve our algorithms and Services

3. AI and Automated Processing

Our Services use artificial intelligence to provide core functionality. We want you to understand exactly how your data is processed by AI systems.

3a. Meal Plan Generation

When you request meal plans, the following data is sent to our AI provider to generate personalized meals: your age, sex, height, weight, activity level, calorie and macronutrient targets, dietary preferences, food allergies, food dislikes, cooking skill level, grocery budget, and any relevant health condition or medication nutrient adjustments. The AI generates meal options with ingredients and cooking instructions based on this profile.

3b. Health Data Validation

When you enter certain health information during the survey — such as medications, medical conditions, or performance enhancement substances — this data may be sent to our AI provider for validation purposes, including checking dose ranges, identifying potential nutrient interactions, and flagging health considerations.

3c. Nutritional Chat Assistant

When you use the in-app chat, your messages and your current health profile are sent to our AI provider so the assistant can provide contextually relevant nutritional guidance. Your conversation history within a chat session is also included for continuity.

3d. Nutritional Validation

AI-generated meal nutritional data may be cross-referenced with the USDA FoodData Central database to verify accuracy. Ingredient names and quantities are sent to the USDA's publicly available database for this validation.

Our AI providers process your data only to fulfill our requests and do not use your personal information to train their models or for any purpose other than providing responses to us on your behalf.

4. Third-Party Service Providers

We use the following categories of third-party service providers to operate our Services:

• AI processing providers — We use Anthropic (Claude) as our primary AI provider for meal generation, health data validation, and chat assistance. Data sent to these providers is used solely to process our requests and generate responses.
• Authentication providers — If you choose to sign in with Google or Apple, your authentication token is verified with the respective provider. We receive only your email address and, optionally, your name.
• Email delivery services — We use a third-party email service to deliver password reset codes and launch notification emails. The service receives only the recipient email address and message content.
• Nutritional databases — We query the USDA FoodData Central database to validate the nutritional accuracy of AI-generated meals. Only ingredient names and quantities are sent; no personal information is included in these queries.

All third-party service providers are contractually bound to use your information only for the purpose of providing services to us and are prohibited from using it for their own purposes.

5. Information Sharing and Disclosure

We do not sell, rent, or share your personal information with third parties for their direct marketing purposes.

We may disclose your information only in the following circumstances:

• Service providers — As described in Section 4, to third-party providers who perform services on our behalf
• Legal requirements — If required by law, regulation, subpoena, court order, or other legal process
• Safety — If we believe disclosure is necessary to protect the rights, property, or safety of Tailored Nutrition, our users, or the public
• Business transfers — In connection with a merger, acquisition, or sale of all or a portion of our assets, in which case you will be notified via a prominent notice on our Website or within the App
• Anonymized feedback — Feature requests and bug reports you submit through the in-app feedback system are displayed to other users in an anonymized form (your name and email are never shown)

6. Cookies and Tracking Technologies

Our Website does not use third-party tracking cookies, analytics services, or advertising pixels. We do not track your activity across other websites. No third parties collect personally identifiable information about your online activities through our Website.

Our App uses local device storage (secure storage for authentication tokens) but does not use third-party analytics SDKs, advertising identifiers, or cross-app tracking.

7. Do Not Track Signals

Our Website and App do not track users across third-party websites or apps and therefore do not respond to Do Not Track (DNT) browser signals. No third-party tracking occurs through our Services.

8. Data Retention

• Active accounts — We retain your personal information for as long as your account is active and you continue to use the Services.
• Account deletion — When you delete your account (available in the App under Profile settings), all of your personal data — including your survey responses, health data, meal plans, food and weight logs, chat history, grocery data, notification data, and meal preferences — is permanently deleted. This action is irreversible.
• Website email signups — Email addresses collected for launch notifications are retained until you unsubscribe or request deletion.
• Password reset codes — Reset codes expire automatically after 15 minutes and are then deleted.
• Authentication tokens — Revoked tokens are stored only until their original expiration (24 hours) and then automatically purged.

9. Data Security

We implement the following security measures to protect your personal information:

• Password hashing — Passwords are hashed using bcrypt, an industry-standard algorithm. We never store plaintext passwords.
• Authentication tokens — Stored in your device's secure storage (Expo SecureStore), not in plaintext or local storage.
• Token revocation — Logout and account deletion immediately invalidate your authentication token.
• File permissions — Server-side data files are restricted to owner-only access (mode 0600 on Unix systems).
• Atomic writes — Data is written using atomic file operations to prevent data corruption.
• Input validation — All user inputs are validated and sanitized to prevent injection attacks (XSS, path traversal).
• Rate limiting — Authentication endpoints are rate-limited to prevent brute-force attacks.

While we take reasonable measures to protect your information, no method of electronic storage or transmission is completely secure. We cannot guarantee absolute security.

10. Your Rights and Choices

You have the following rights regarding your personal information:

• Access — You may request to know what personal information we hold about you. Within the App, you can view all your stored data at any time through your Profile.
• Correction — You may update your survey responses, name, and email address at any time within the App. You may also request corrections by contacting us.
• Deletion — You may delete your entire account and all associated data at any time through the App (Profile > Delete Account). You may also request deletion by contacting us; we will comply within 30 days.
• Opt-out of communications — You may unsubscribe from email communications at any time by using the unsubscribe link included in every email, or by contacting us directly.
• Notification control — You may customize or disable any category of in-app notifications through the App's notification preferences.
• Data portability — You may request a copy of your personal data in a commonly used electronic format. Contact us to make this request.

To exercise any of these rights, contact us at the address listed in Section 14.
