Our Commitment

Kalon is built on a simple principle: your personal data belongs to you. We collect only what's necessary to provide personalized strategy coaching, and we never sell, share, or monetize your behavioral data.

Information We Collect

Account Information — Email address and password for authentication. Managed securely through Supabase.

Diagnostic Responses — Your answers to the 20-question assessment. Used to calculate your dimension scores and assign your persona.

Behavioral Feedback — Your interactions with levers — thumbs up/down, completions, pauses, daily check-ins. Used to improve future recommendations.

Journal Entries — Personal reflections you write in the premium journal. Used only to improve lever and insight accuracy for your account.

Optional Data (Consent Required)

The following data sources are entirely optional. Each is independently toggled in Settings and never collected without your explicit consent.

Screen Time — App usage patterns to understand digital habits. No specific app names are stored — only aggregate patterns.

Health Data — Steps, sleep, heart rate, and other HealthKit metrics. Read-only access — Kalon never writes to HealthKit.

Location Patterns — Significant location changes and visit patterns. Used for routine detection, not tracking. Battery-efficient collection only.

Photo Context — Photo metadata only (dates, locations). Kalon never inspects, reads, or stores the content of your images.

How We Use Your Data

Personalization — Your diagnostic scores and feedback train the AI to generate levers tailored to your patterns.

Pattern Analysis — Behavioral signals (when consented) help Kalon surface insights about your routines and tendencies.

Score Reinforcement — Over time, your dimension scores adjust based on behavioral signals — always decaying toward the mean to prevent extremes.

Data Storage & Security

Your data is stored locally on your device using SwiftData and synced to Supabase PostgreSQL with Row Level Security. Only your authenticated account can access your data. AI-generated content is cached locally to reduce API calls.

Third-Party Services

Supabase — Authentication and cloud database. Your data is protected by Row Level Security policies.

OpenAI — Generates lever content and insights. We send anonymized context (dimension scores, persona, feedback patterns) — never raw personal data or identifiers.

Apple HealthKit — Read-only health data access when consented. Data stays on-device and in your Kalon account.

Your Rights

Access — View all your data in the app — diagnostic scores, persona, levers, reflections, and feedback history.

Reset — Recalculate your interpretations at any time from Settings without deleting your raw data.

Delete — Permanently delete all your data from Settings. This removes everything from both your device and our servers.

Revoke Consent — Toggle off any optional data source at any time. Previously collected signals are retained but no new data is gathered.

Account Deletion — Delete your account entirely from Settings. This is permanent and cannot be undone.

Children's Privacy

Kalon is not designed for or directed at children under 13. We do not knowingly collect personal information from children.

Changes to This Policy

We may update this policy as Kalon evolves. Significant changes will be communicated through in-app notifications. Continued use after changes constitutes acceptance.
