Privacy Policy

Last Updated: March 7, 2026

1. Introduction

Nulve ("the App") is operated by Daniel Munoz, an individual based in California, USA. This Privacy Policy explains how we collect, use, store, share, and protect your personal information when you use the App. By using Nulve, you consent to the practices described in this policy.

2. Information We Collect

2.1 Account Information

  • Email address
  • Password (encrypted and hashed — we never store plaintext passwords)
  • Display name

2.2 Profile Information

  • Wake time and bedtime preferences
  • Caffeine sensitivity level
  • Dietary preferences and restrictions

2.3 Health and Performance Data

  • Meal nutrition data (generated by AI analysis of your meal photos)
  • Caffeine intake logs
  • Cognitive test results (PVT, SDMT, N-Back, Flanker)
  • Context flags (e.g., stress level, hydration)

2.4 Meal Photos

Meal photos are NOT stored. When you photograph a meal, the image is sent to our AI providers for analysis, and the extracted nutritional data is saved. The photo itself is processed in real time and immediately discarded. We do not retain, store, or have access to your meal photos after processing.

2.5 Apple Health Data (Optional)

If you choose to connect Apple Health, Nulve may read:

  • Sleep data (stages, duration, in-bed time)
  • Step count
  • Activity data

Apple Health data is read only with your explicit permission and is never shared with third parties for advertising or marketing purposes.

2.6 Analytics Data

We collect anonymous usage analytics via Mixpanel, including:

  • App usage patterns and screen views
  • Feature engagement metrics
  • Device type and operating system version

Analytics data is used to improve the App and is not linked to your personal identity.

2.7 Information We Do NOT Collect

  • Location data
  • Contacts
  • Browsing history
  • Data from other apps on your device

3. How We Use Your Data

We use your information to:

  • Provide the core service: Clarity Scores, Fuel Scores, Deep Focus Window predictions, and AI coaching.
  • Personalize your experience based on your profile, preferences, and historical patterns.
  • Process meal photos through AI models to generate nutritional analysis.
  • Improve the App using anonymized, aggregated data that cannot identify you.
  • Communicate with you via in-app notifications about your performance trends and App updates.
  • Manage your subscription and validate your purchase entitlements.

4. AI Data Processing

Nulve uses the following AI providers to deliver its core features:

  • Google Gemini — Processes meal photos to identify foods and estimate nutritional content.
  • Anthropic Claude — Powers the real-time coaching chat and generates pattern-based insights from your historical data.

From Nulve's side: We do not store the content of AI interactions. Meal photos, coaching conversations, and related data are processed in real time and are not retained on Nulve's servers beyond what is needed to deliver the immediate response.

From AI providers' side: Anthropic and Google may process data transmitted via their APIs in accordance with their own data usage and retention policies. Nulve uses these providers' API services, which are generally governed by separate data processing terms. We encourage you to review:

  • Anthropic's API data usage policy at anthropic.com
  • Google's API data usage policy at cloud.google.com

Nulve selects API configurations designed to minimize data retention by third-party providers wherever available.

5. Data Sharing

We do NOT sell your personal information. Ever.

We share data only with the following service providers, solely for the purpose of operating the App:

  • Supabase — Database and authentication infrastructure. Data is stored on Supabase servers located in the United States.
  • Mixpanel — Anonymous usage analytics.
  • Anthropic (Claude) — AI coaching and pattern analysis.
  • Google (Gemini) — AI meal photo analysis.
  • Apple (HealthKit) — Sleep and activity data synchronization (user-initiated only).
  • Apple (App Store) — Payment processing.
  • RevenueCat — Subscription management, purchase validation, and entitlement tracking. RevenueCat receives an anonymous user identifier, subscription status, and purchase history. RevenueCat does not receive your name, email, health data, or meal information.

We may also disclose your information if required by law, regulation, or legal process, or if we believe disclosure is necessary to protect the rights, safety, or property of Daniel Munoz, our users, or the public.

In the event of a business transfer (acquisition, merger, or sale of assets), your data may be transferred to the acquiring entity. We will provide notice before your data is subject to a different privacy policy.

6. Data Storage and Security

  • Your data is stored on Supabase servers located in the United States.
  • All data is encrypted in transit using TLS/SSL and encrypted at rest.
  • Passwords are cryptographically hashed and never stored in plaintext.
  • We retain your data for as long as your account is active.
  • After account deletion, all personal data is permanently deleted within 30 days.

While we implement industry-standard security measures, no method of electronic storage or transmission is 100% secure. We cannot guarantee absolute security of your data.
