Cookie Policy: How We Use Cookies & Tracking Technologies on Our AI Nutrition Platform
Quick Answer: We use essential cookies for site functionality, preference cookies for personalization, and analytics cookies to improve our AI nutrition recommendations. All cookies comply with GDPR, CCPA, and ePrivacy regulations. You can manage or disable cookies anytime through your browser settings or our consent panel. No cookies are used to sell your personal data to third parties.

What Are Cookies & Why Do We Use Them?
Cookies are small text files that websites store on your device (computer, smartphone, or tablet) when you visit them. Think of them as tiny memory aids that help websites remember information about your visit β like your language preference, login status, or items in a shopping cart. Without cookies, the web would be much less convenient: you'd have to re-enter your preferences every time you loaded a new page.
On our AI nutrition platform, cookies serve several important purposes that directly enhance your experience:
- Personalization: Remembering your dietary preferences (keto, vegan, etc.), macro targets, and meal planning settings so you don't have to reconfigure them on every visit
- Session Management: Keeping you logged in securely as you navigate between pages, log meals, or view your progress reports
- Performance Optimization: Loading pages faster by caching static resources and reducing server requests
- Analytics & Improvement: Understanding which features you use most, where you encounter difficulties, and how we can make our AI recommendations more helpful
- Security: Protecting your account from unauthorized access and detecting suspicious activity
- AI Model Training (Anonymized): Aggregated, de-identified usage patterns help our machine learning systems improve recommendation accuracy for all users β without ever accessing your personal identity
Important clarification: We do NOT use cookies to: sell your personal data to advertisers, track your activity across unrelated websites, build detailed profiles for third-party marketing, or share your health information with external parties without your explicit consent.
First-Party vs. Third-Party Cookies
Understanding this distinction helps you make informed choices about your privacy:
- First-party cookies: Set by nutrition.web2ai.eu directly. These handle core functionality like login sessions, preference storage, and site performance. They cannot be read by other websites.
- Third-party cookies: Set by external services we integrate (like Google Analytics for traffic analysis). These help us understand usage patterns but are governed by the third party's own privacy policies.
We minimize third-party cookies and only use them when they provide clear value to your experience. All third-party integrations undergo privacy and security review before implementation.
Types of Cookies We Use
We categorize cookies by purpose and duration to give you transparent control over your data. Here's a complete breakdown:
π By Purpose
Essential / Strictly Necessary Cookies
These cookies are required for the basic operation of our website. Without them, core features like secure login, meal logging, and account management would not function. They do not store personally identifiable information and cannot be disabled through our consent panel (though you can block them via browser settings, with potential functionality loss).
Examples: Session authentication tokens, CSRF protection cookies, load balancer identifiers.
Preference / Functionality Cookies
These remember choices you make to personalize your experience: language selection, theme preference (light/dark mode), default macro targets, or saved meal templates. They make the site more convenient but are not strictly required for operation.
Examples: Preferred measurement units (metric/imperial), default meal plan view, notification preferences.
Analytics / Performance Cookies
These help us understand how visitors interact with our platform: which pages are most visited, where users encounter errors, how long people spend on specific features. This data is aggregated and anonymized β we cannot identify individual users from analytics cookies alone. The insights drive improvements to our AI algorithms and user interface.
Examples: Page view counters, feature usage tracking, error reporting identifiers.
AI Optimization Cookies
Unique to our platform, these cookies support our machine learning systems. They store anonymized interaction patterns (e.g., "user accepted 80% of protein recommendations") that help our AI learn which suggestions are most helpful. All data is pseudonymized and aggregated before model training; no individual health records are used to train AI systems.
Examples: Recommendation acceptance rates, feedback signal identifiers, personalization preference hashes.
β±οΈ By Duration
Session Cookies
Temporary cookies that expire automatically when you close your browser. They handle short-term tasks like keeping you logged in during a single browsing session or maintaining your shopping cart contents while you browse.
Typical lifespan: Until browser closure (usually minutes to hours).
Persistent Cookies
These remain on your device for a defined period after your session ends. They enable longer-term conveniences like "remember me" login, saved preferences, or analytics tracking across multiple visits.
Typical lifespan: 30 days to 2 years, depending on purpose. All expiration dates are clearly documented in our cookie table below.
First-Party Persistent vs. Session Balance
We follow a "minimal persistence" principle: cookies last only as long as necessary for their purpose. Session cookies handle sensitive operations; persistent cookies are reserved for non-sensitive preferences you explicitly choose to save.

AI & Analytics: How Cookies Improve Your Experience Without Compromising Privacy
As an AI-powered nutrition platform, we use data to make our recommendations smarter. But we do this responsibly. Here's exactly how cookies support our AI systems while protecting your privacy:
π€ Anonymized Learning, Not Personal Profiling
When you interact with our AI meal planner β accepting a suggestion, modifying a recipe, or rating a recommendation β we may store a pseudonymized signal (via the ai_feedback_hash cookie) that helps our machine learning models learn which approaches work best. Crucially:
- β
This signal is not linked to your identity β it's a random hash that cannot be reversed to identify you
- β
Data is aggregated across thousands of users before model training; no individual's data is used in isolation
- β
Health information (weight, macros, meals) is never used to train AI models without explicit, opt-in consent
- β
You can opt out anytime via your account settings or by disabling analytics cookies
π Analytics That Respect Boundaries
Our Google Analytics implementation follows strict privacy-by-design principles:
- IP Anonymization: Your IP address is truncated before storage, preventing geographic identification
- No Cross-Site Tracking: We disable Google's advertising features and data sharing with other Google services
- Retention Limits: Analytics data is automatically deleted after 14 months
- Health Data Exclusion: Pages containing personal health information are excluded from analytics tracking entirely
Bottom line: Cookies help us build a better AI nutrition tool for everyone, but your personal health journey remains private and under your control.
Third-Party Cookies & Partners: Who Else Might Set Cookies?
While we minimize external dependencies, some features require integration with trusted third-party services. Here's a transparent overview:
β
Currently Integrated Services
π« Services We Do NOT Use
To protect your privacy, we explicitly avoid:
- β Advertising networks (Google Ads, Facebook Pixel, etc.)
- β Social media tracking widgets (Facebook Like buttons, Twitter share counters)
- β Affiliate marketing cookies that track purchases across sites
- β Data brokers or audience segmentation platforms
- β Any service that sells user data to third parties
π How We Evaluate New Integrations
Before adding any third-party service, we conduct a privacy impact assessment evaluating: data collection scope, retention policies, security practices, and compliance with GDPR/CCPA. Only services meeting our strict standards are approved.
How to Manage or Disable Cookies: Full Control in Your Hands

- β
Reject all non-essential cookies (minimal functionality, maximum privacy)
- β
Review and adjust choices anytime via the "Cookie Settings" link in our footer
π Method 2: Browser Settings (Most Comprehensive)
