Privacy Policy

Last updated: April 2026

At AdaptNX, protecting your personal and health data is a core responsibility. This Privacy Policy explains what information we collect, how we use it, who we share it with, and what rights you have over your data. Because AdaptNX processes sensitive health information, we have designed our data practices to meet the requirements of the EU General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA), and other applicable privacy laws.

1. Information We Collect

We collect the following categories of information to provide our service:

1.1 Account Data

  • Full name and email address (collected at registration)
  • Authentication data (OTP codes, session tokens stored as httpOnly cookies)

1.2 Health Metrics

  • Heart Rate Variability (HRV) — entered manually or synced from wearables
  • Sleep duration, quality scores, and sleep stage data
  • Stress levels and readiness scores
  • Resting heart rate
  • Daily step counts and activity data
  • Screenshots submitted for AI-based metric extraction (images are analyzed and not stored after extraction)

1.3 Blood Test Results

  • Biomarker results you upload or enter manually
  • All blood test data is encrypted at rest using Fernet symmetric encryption

1.4 Nutrition Data

  • AI-generated meal plans and your daily nutrition logs
  • Food photos submitted for calorie and macro estimation (not stored after analysis)
  • Pantry inventory and recipe preferences

1.5 Device & Technical Data

  • Browser type, operating system, and device type
  • IP address (used for security and fraud prevention; not linked to health data)
  • Session identifiers and authentication tokens

1.6 Wearable Integration Data

  • Health and activity data synced via OAuth integrations with Oura, Whoop, Fitbit, and Huawei Health
  • OAuth access tokens stored securely to enable ongoing data synchronization
  • Only data types you explicitly authorize during the OAuth flow are collected

2. How We Use Your Information

We use your data for the following purposes, each grounded in a lawful basis under GDPR:

  • Service Delivery (Contract Performance): Generating personalized, AI-adapted nutrition plans based on your health metrics and physiological state
  • Health Trend Analysis (Contract Performance): Analyzing your metrics over time to provide progress reports and adaptive recommendations
  • Communications (Legitimate Interest / Consent): Sending transactional emails including OTP verification codes, plan generation notifications, and service updates
  • Service Improvement (Legitimate Interest): Using aggregated, anonymized data to improve AI model accuracy and overall service quality. Individual health data is never used in identifiable form for model training without explicit consent
  • Security & Fraud Prevention (Legitimate Interest): Monitoring for unauthorized access, detecting abuse, and maintaining platform security
  • Legal Compliance (Legal Obligation): Complying with applicable laws, regulations, and lawful requests from authorities

3. AI Processing of Your Health Data

AdaptNX uses Google Gemini AI models to process your health data and generate personalized nutrition plans. This is a core function of the service and requires transmitting health metric data to Google's AI infrastructure.

3.1 Nutrition Plan Generation

Your health metrics (HRV, sleep, stress, steps, blood test markers) are included in AI prompts sent to Google Gemini to generate contextually appropriate meal plans. Only the data necessary to generate the plan is included in each request.

3.2 Screenshot Analysis

Screenshots you upload (e.g., from wearable apps) are analyzed by AI to extract health metrics. The image itself is not stored after the extraction is complete — only the extracted numerical values are saved to your profile.

3.3 Food Photo Analysis

Food photos submitted for calorie and macro estimation are sent to Google Gemini for visual analysis. As with screenshots, the image is not stored after analysis is complete.

3.4 Automated Decision-Making

Nutrition plans are generated automatically by AI without human review. Under GDPR Article 22, you have the right to request human review of any automated decision that significantly affects you. Contact [email protected] to exercise this right.

4. Data Storage & Security

4.1 Encryption at Rest

Sensitive health data — including blood test results, health metric columns, and authentication tokens — is encrypted at rest using Fernet symmetric encryption (AES-128-CBC with PKCS7 padding and HMAC-SHA256 authentication). Encryption keys are managed separately from the data they protect.

4.2 Encryption in Transit

All data transmitted between your device and AdaptNX is protected by HTTPS/TLS. Cloudflare provides SSL termination and DDoS protection at the edge.

4.3 Server Location

Your data is stored on servers located in the European Union — specifically Oracle Cloud Infrastructure in the Stockholm (EU-Stockholm-1) region. This ensures that primary data storage complies with EU data residency principles under GDPR.

4.4 Access Controls

Access to production systems and databases is restricted to authorized personnel only, protected by SSH key authentication, VPN, and principle-of-least-privilege access controls. We do not share database access with third parties.

4.5 Breach Notification

In the event of a data breach that poses a risk to your rights and freedoms, we will notify you and the relevant supervisory authority within 72 hours of becoming aware of the breach, as required by GDPR Article 33.

5. Data Retention

  • Account data (name, email): Retained for the duration your account is active, plus a brief administrative period after deletion
  • Health metrics and nutrition logs: Retained until you delete them individually or delete your account
  • Blood test results: Retained until you delete them or request account deletion
  • Screenshot and food photo content: Deleted immediately after AI extraction/analysis is complete — not stored
  • Session tokens: Expire after a defined inactivity period (rolling expiry)
  • On account deletion: All personal data is permanently and irreversibly deleted from our systems within 30 days of your deletion request. Backups containing your data are purged on their normal rotation schedule

6. Data Sharing & Third-Party Processors

We do NOT sell, rent, or trade your personal or health data to any third party.

We share data only with the following third-party service providers ("data processors") who process data on our behalf and under strict data processing agreements:

Google (Gemini AI)

Processes health metric data and images to generate nutrition plans. Subject to Google Cloud Data Processing Addendum and Google's privacy commitments.

Resend

Handles transactional email delivery (OTP codes, notifications). Only receives your email address for the purpose of delivery.

Cloudflare

Unsplash

Provides food and recipe imagery displayed within the application. No personal data is shared with Unsplash.

Wearable Providers (Oura, Whoop, Fitbit, Huawei)

OAuth-based integrations. Data flows from these providers to AdaptNX, not the other way. Your authorization with each provider is governed by their own privacy policies.

We may also disclose your information if required by law, court order, or governmental authority, or if we believe disclosure is necessary to protect the safety of any person or to prevent fraud or illegal activity.

12. Cookies & Local Storage

9.1 Essential Cookies

AdaptNX uses a single essential authentication cookie:

Name: auth_token (or equivalent session identifier)

Type: httpOnly, Secure cookie

Purpose: Maintains your authenticated session

Duration: Session-based with rolling expiry

This cookie is strictly necessary for the service to function and cannot be disabled. It does not track you across websites.

9.2 No Tracking or Analytics Cookies

We currently do not use any third-party tracking cookies, advertising cookies, or analytics platforms (such as Google Analytics). We do not engage in cross-site behavioral tracking.

9.3 Cookie Consent

Cookie consent is managed via a banner displayed on your first visit. Because we only use strictly necessary cookies, no consent is required under ePrivacy Directive rules. Should we introduce non-essential cookies in the future, we will update this policy and obtain appropriate consent before setting them.

13. Children's Privacy

AdaptNX is not intended for use by individuals under the age of 16. We do not knowingly collect personal data from children under 16. If we become aware that we have inadvertently collected personal data from a person under 16, we will delete that data promptly.

If you believe a child under 16 has provided us with personal information, please contact us immediately at [email protected].

14. International Data Transfers

Your primary data is stored within the European Union (Oracle Cloud, Stockholm). However, certain service operations involve international data transfers:

  • AI Processing (Google Gemini): Health metric data is transmitted to Google's AI infrastructure, which may process data in data centers globally, including outside the EEA. These transfers are conducted under Google's Standard Contractual Clauses (SCCs) as approved by the European Commission
  • Email Delivery (Resend): Your email address is transmitted to Resend for transactional email delivery. Resend operates under appropriate data transfer safeguards
  • CDN (Cloudflare): Network traffic may be routed through Cloudflare edge nodes globally. Cloudflare participates in the EU-US Data Privacy Framework and operates under SCCs

Where your data is transferred outside the EEA, we ensure that appropriate safeguards are in place as required by GDPR Chapter V, including Standard Contractual Clauses, adequacy decisions, or other approved transfer mechanisms.
