Pulse - Privacy Policy

**Effective Date:** May 14, 2026
**Last Updated:** May 14, 2026

Welcome to **Pulse** (also known as **Wellness OS**) ("we," "our," "us," or "the App"). The App is a personal wellness companion that helps you reflect on and track six everyday areas — sleep, mind, fitness, nutrition, hydration, and fasting — and provides AI-powered coaching, insights, and reminders based on the information you choose to share.

BY USING THE APP, YOU AGREE TO THIS PRIVACY POLICY. IF YOU DO NOT AGREE, DO NOT USE THE APP.

---

**1. What This Policy Covers**

This Privacy Policy explains: (a) what information we collect, (b) how we use it, (c) what we share, (d) how we secure it, and (e) the choices you have.

---

**1.5 Important Health Disclaimer**

⚠️ THE APP IS NOT A MEDICAL DEVICE OR HEALTHCARE PROVIDER

The App is a personal reflection and wellness companion for general awareness only. It is NOT:
❌ Medical advice, diagnosis, or treatment
❌ A substitute for professional medical care
❌ A health monitoring or diagnostic device
❌ Intended to detect, prevent, treat, or cure any medical condition

The App provides personalized coaching messages, insights, reminders, and chat responses that are generated by artificial intelligence based on the information you provide. These outputs are for **informational and motivational purposes only** and are NOT medical recommendations.

If you are experiencing a medical or mental health emergency:
- Call emergency services (911 in the US)
- Contact a mental health crisis line
- Seek immediate professional help

Always consult qualified healthcare professionals for medical concerns. Do not disregard professional medical advice or delay seeking it because of anything in the App.

---

**2. Core Privacy Commitments**

The App is built with privacy-first defaults:
✅ No selling of personal data
✅ No third-party advertising networks or ad profiling
✅ No precise location requirement (the App does not require GPS to function)
✅ No contacts access (the App does not read your address book)
✅ Voice logging is processed **entirely on your device** — audio is never uploaded
✅ Limited third-party analytics (anonymized usage data only)
✅ Optional notifications (push reminders require your iOS permission)
✅ Payments handled by Apple (we do not store your full card details)
✅ Ad attribution uses only anonymous signals — we measure whether our own ads lead to app installs, not to build profiles or track you across other apps

---

**3. Information We Collect**

**3.1 Profile Information You Provide**

During onboarding and personalization, you may provide:
- First name or display name (optional)
- Age or age range
- Gender
- Height and weight (used only to personalize coaching targets)
- Wake time, bedtime, activity level
- Preferences such as dietary style, allergies, training level, equipment access, fasting protocol, and topics you want help with

This information is used solely to personalize your coaches and recommendations.

**3.2 Wellness Logs and User Content**

When you use the App, you may log:
- Sleep entries (bedtime, wake time, quality, disruptors)
- Mood, emotion, anxiety level, and trigger check-ins
- Meal entries (food name, calories, macros, optional photo)
- Workouts (exercises, sets, reps, weight, RPE, notes)
- Water intake (volume, beverage type)
- Fasting windows (start, end, duration, stage)
- Free-text notes and chat messages with your AI coaches

These are stored on your device and on our servers so the App can show your history, calculate scores, and personalize your coaching.

**3.3 Identifiers**

- **Device ID**: A unique identifier from your device (used for authentication, account identification, and data sync without requiring a traditional username/password login)
- **User ID**: Your account identifier tied to your device, display name, and app data
- **Advertising Identifier (IDFA)**: Only collected if you grant permission via Apple's App Tracking Transparency (ATT) prompt. Used solely to measure whether our own ads led to an install or trial start. If you deny ATT permission, your IDFA is never collected.

**3.4 Usage Data (Product Interaction)**

To operate the core features and improve the App, we collect:
- Coach log events and timestamps (when you log sleep, meals, workouts, etc.)
- Streak counts and last-log times per coach
- Reminder and frequency settings
- Feature usage patterns (which features you use and how often)
- App interaction data (launches, navigation, settings changes)
- Anonymized analytics (feature interactions, screen views, button clicks)
- Anonymized conversion events (trial started, subscription started) for advertising attribution — see Sections 8.5 and 8.6

**3.5 Technical and Diagnostic Data**

- Crash logs and error reports (to maintain app stability and fix bugs)
- Device model and iOS version (to ensure compatibility)
- App version, locale, time zone
- Anonymized usage analytics via Mixpanel (feature interactions, screen views, app performance metrics)

**3.6 Purchase and Subscription Data**

- If you purchase a premium subscription, your payment is processed entirely by the Apple App Store
- We do not store your full payment details
- Premium is available as a weekly, monthly, or yearly subscription, and may include a free trial
- After any trial ends, your subscription renews automatically through Apple unless cancelled
- Subscription management (purchase verification, trial tracking, renewal status) is handled by RevenueCat on our behalf. RevenueCat receives anonymized subscription event data (e.g., subscription started, trial converted, subscription expired) tied to a RevenueCat-generated user identifier. No payment card details are shared with RevenueCat.
- The App stores subscription state locally and on our servers to unlock premium features on your device

**3.7 Push Notification Permission Status**

- If you enable reminders, iOS will ask for notification permission
- The App checks whether permission is enabled to schedule coach reminders and timely nudges

**3.8 Voice (Optional Feature)**

- When you use voice logging, speech is transcribed entirely **on your device** using on-device models
- Audio recordings are **never uploaded** to our servers or any third party
- Only the transcribed text becomes part of your log, the same as if you had typed it

**3.9 Photos (Optional Feature)**

- When you photograph a meal, the image is processed by AI to extract food and macros
- The photo is sent only to our AI vision provider for that single request
- Photos are not retained on our servers after processing unless you choose to save them with the log

---

**4. Information We Do NOT Collect**

The App does not require or collect:
❌ Precise location (GPS / geolocation)
❌ Access to your contacts or address book
❌ Health data from Apple HealthKit or similar services
❌ Advertising identifiers for cross-app tracking or third-party ad profiling
❌ Biometric data
❌ Financial information (handled by Apple)
❌ Browsing history or search history outside the App
❌ Audio recordings from voice logging (processed on-device only)

Note: We collect IDFA only if you grant ATT permission, and only for measuring our own ad campaign performance — not for third-party ad networks or profiling.

---

**5. How We Use Information**

**5.1 Provide Core Functionality**

- Authenticate you using your Device ID (no password required)
- Show your six wellness coaches (sleep, mind, fitness, nutrition, hydration, fasting) and the data you've logged for each
- Calculate and display your Wellness Score, coach scores, streaks, and trends
- Surface cross-coach insights (for example, patterns linking sleep and mood)
- Personalize coaching messages, reminders, and suggested actions based on your inputs and goals

**5.2 AI-Generated Coaching, Insights, and Chat**

- Generate personalized coaching messages, daily actions, weekly summaries, and chat responses based on your profile and recent logs
- See Section 8 for the AI providers involved and what is shared with them
- AI outputs are informational only and never replace professional advice

**5.3 Notifications and Reminders**

- Send local push reminders (only if you grant notification permission)
- Send proactive coach nudges based on your activity patterns and the settings you choose
- Support in-app and email alert preferences (as toggled in Settings)

**5.4 Premium Subscriptions**

- Verify and manage your premium subscription via Apple and RevenueCat
- Unlock premium features for active subscribers
- Manage trial periods, subscription renewals, and expiration
- Sync subscription state between Apple, RevenueCat, and our servers to ensure uninterrupted access

**5.5 Analytics and App Improvement**

We analyze usage patterns to:
- Understand how the App is used
- Evaluate the effectiveness of existing features
- Plan and develop new features
- Measure app stability, performance, and reliability
- Identify and fix bugs and technical issues
- Improve user experience and interface design

Important: Analytics data is anonymized and used internally. We use Mixpanel for product analytics, but no personally identifiable information (names, emails) is sent to Mixpanel.

**5.6 Advertising Attribution**

We run ads on Meta (Facebook / Instagram) and Google to help people discover the App. To measure whether our ads are working, we:
- Report anonymous conversion events (trial started, subscription started) to Meta and Google
- Use Apple's SKAdNetwork framework for privacy-safe attribution — this always sends anonymous signals to ad platforms regardless of your ATT choice, and contains no personal data
- If you grant ATT permission: your IDFA may be shared with Meta and Google to more accurately measure our ad campaigns
- If you deny ATT permission: only anonymous SKAdNetwork signals are used — no personal identifiers are shared

We do NOT use this data to build advertising profiles, retarget you across other apps, or sell your data to ad networks.

**5.7 Safety, Security, and Fraud Prevention**

- Prevent abuse and fraudulent use of the App
- Ensure data security and system integrity
- Troubleshoot technical issues and provide customer support
- Comply with legal obligations

---

**6. How Data is Linked to You**

Most data collected by the App is linked to your user identity via:
- Your Device ID (primary identifier)
- Your User ID and display name

Exception: Mixpanel analytics data is anonymized and not directly linked to your personal identity. Advertising attribution data is either anonymous (SKAdNetwork) or linked only to your advertising identifier (IDFA), not to your in-app account.

We do not anonymize core app data (your wellness logs, profile, coach chats) because it is essential for the App to function (for example, to show YOUR Wellness Score, YOUR streaks, and YOUR personalized coaching).

---

**7. Tracking and Advertising**

**7.1 What We Do**

We run advertising campaigns on Meta (Facebook / Instagram) and Google Ads to help people discover the App. To measure whether these campaigns result in installs and trial starts, we use:

- **Apple SKAdNetwork**: Apple's privacy-preserving attribution framework. Anonymous signals are always sent to ad platforms when conversions happen — this contains no personal data and happens regardless of your ATT permission choice. This is required by Apple's framework.
- **Meta (Facebook) SDK**: Reports anonymous conversion events. If you grant ATT permission, your IDFA may be included to improve attribution accuracy. If you deny, only aggregated / modeled data is used.
- **Firebase Analytics (Google)**: Reports anonymous app events for Google Ads attribution. Subject to Google's privacy policy.

**7.2 What We Do NOT Do**

❌ We do NOT link your data with third-party data for advertising profiling
❌ We do NOT share data with data brokers
❌ We do NOT use your data for third-party advertising networks
❌ We do NOT run retargeting campaigns based on your in-app behavior
❌ We do NOT track you across other companies' apps or websites

**7.3 Your ATT Choice**

On iOS 14 and later, when you first open the App, you will see Apple's App Tracking Transparency prompt asking if you want to allow tracking. You can:

- **Allow**: Your IDFA is used to measure our ads more accurately
- **Don't Allow**: Only anonymous SKAdNetwork signals are used — your IDFA is never collected

You can change this choice at any time: iOS Settings → Privacy & Security → Tracking.
