Privacy Policy
Last updated: August 31, 2026
Introduction
Welcome to Northe (“we,” “our,” or “us”). We are committed to protecting your privacy and being transparent about how we handle your personal information. This Privacy Policy explains our data practices for Northe (“the App”).
Your privacy is our priority. The App is designed with a privacy-first approach, storing your data locally on your device and giving you complete control over how your information is handled.
Information We Collect
Personal Data You Provide
When you use the App, you may provide the following types of personal information:
- Mood Data: Daily mood ratings (1-5 scale), mood types, and associated notes
- Sleep Information: Sleep quality ratings, sleep duration, and sleep-related notes
- Energy Levels: Daily energy ratings and related observations
- Personal Reflections: Gratitude entries, daily highlights, areas for improvement, and future priorities
- Decision Tracking: Decision confidence levels, important decisions, frameworks used, outcomes, and notes
- Daily Questions: Your responses to reflective questions across various categories
- Challenge Progress: Completion status, preferences, and timestamps for personal growth challenges
- Mental Model Applications: Information about which thinking frameworks you apply and when
Automatically Collected Data
- Usage Patterns: When you use the App, completion rates, and interaction patterns (stored locally only)
- App Performance: Technical information needed for the App to function properly
Wellbeing Data
- Self-Reported Only: Mood, energy, and sleep quality are the values you enter yourself in the App
- The App does not read from Apple Health and requests no Health permissions
How We Store Your Data
Local Storage (Primary Method)
- Your data is stored locally on your device in encrypted files
- Data is protected using iOS complete file protection (encrypted when device is locked)
- We use atomic file writes to ensure data integrity
- Storage location: Your device’s Documents directory
iCloud Sync (Optional)
- You control whether your data syncs to iCloud
- iCloud sync can be enabled or disabled in the App’s settings
- When enabled, your data is encrypted and stored in your personal iCloud account
- We cannot access your iCloud data — it belongs to you
- Conflict resolution: In case of sync conflicts, the newest data is preserved
How We Use Your Data
Your personal data is used exclusively to:
- Provide the core functionality of the App
- Generate personalized insights and recommendations
- Track your progress and identify patterns
- Suggest relevant mental models and growth strategies
- Calculate statistical analysis of your personal data trends
Most data processing happens locally on your device. When you use AI coaching features, your tracking data — including reflections — is sent to our secure server for AI processing. Crash reports and anonymous usage analytics are sent to Firebase (Google).
AI Services and Data Processing
AI Services
- AI Processing: AI features are processed through our secure Cloudflare Worker proxy
- Server-Side Keys: API keys are managed server-side, never stored on your device
- What Is Sent: When you use AI coaching or request a Deep Analysis, your daily tracking data — including reflections and journal entries — is sent to our server for processing by third-party providers
- AI Providers: Our proxy routes requests to OpenRouter, Groq, and Hugging Face. If one provider is unavailable the request falls back to the next, so your content may be processed by any of them
- No Personal Identifiers: Your name, email, or other identifying information is never sent
- Per-Device Rate Limiting: Requests carry a randomly generated device identifier so usage can be rate-limited fairly. It is not linked to your name, email, or Apple ID, and it identifies a device rather than a person
- No Server Storage: Your data is not stored on our servers after processing
Data Sharing and Third Parties
We Do NOT Share Your Data For:
- Advertising or marketing purposes
- Analytics or user tracking
- Sale to third parties
- Social media integration
Limited Data Sharing:
- AI Services: When you use AI coaching features, your tracking data — including reflections — is sent to AI providers via our secure proxy
- Firebase (Google): Crash reports and anonymous usage events, as described below
- iCloud: Only if you enable sync, data goes to your personal iCloud account
Analytics and Crash Reporting
- Firebase Crashlytics: Crash reports, device model, OS version, and stack traces are sent to Google for stability monitoring. No personal tracking data is included
- Firebase Analytics: Anonymous usage events — feature usage counts and subscription events — are sent to Google. No mood data, reflections, or personal content is included
- We do not collect advertising IDs or track you across apps or websites
- Your reflections, mood entries, and personal content are never sent to analytics services
Your Rights and Choices

- View Your Data: Access all your stored data within the App
- Delete Data: Remove individual entries or reset all data

Legal Basis for Processing (GDPR)

Summary: Your privacy matters to us. Your entries live on your device, you keep control of them, and we never share your personal information for advertising or marketing. Most processing happens on your device — the exceptions are AI coaching and Deep Analysis, which send your tracking data to our proxy for processing without storing it afterwards, and anonymous crash and usage analytics sent to Firebase.
