Privacy Policy

Kintz ("we," "our," or "us") is a mental wellness and grief support application designed to help you process emotions, track your mood, and journal through your healing journey. We are committed to protecting your privacy and handling your personal information with care and transparency.

This Privacy Policy explains what information we collect, how we use it, who we share it with, and your rights regarding your data. By using Kintz, you agree to the practices described in this policy.

We use your information to:

• Provide core app features: journaling, mood tracking, grief assessment, AI chat, and daily check-ins.
• Personalize your experience: surface relevant recommendations and resources based on your expressed needs.
• Generate AI responses: your chat messages and journal prompts are processed by OpenAI to deliver AI-assisted support.
• Send notifications: reminders for check-ins or journaling, if you have enabled notifications.
• Manage subscriptions: process and validate in-app purchases through RevenueCat.
• Improve the app: analyze aggregated, anonymized usage patterns and crash data to fix bugs and improve features.
• Respond to support requests: if you contact us, we use your information to respond.

We do not use your personal data to train AI models. We do not sell your data to advertisers or data brokers.

Journal entries are end-to-end encrypted before being stored. Your journal content is encrypted on your device using your unique encryption key, and stored encrypted in our database (Supabase). This means we cannot read your journal entries.

We use industry-standard security practices including:

• TLS/HTTPS for all data in transit.
• Encrypted storage for journal entries at rest.
• Supabase Row-Level Security (RLS) to ensure users can only access their own data.

Despite these measures, no system is completely immune to security risks. We encourage you to use a strong, unique password for your linked Google or Apple account.

We use the following third-party services. Each operates under its own privacy policy.

OpenAI Data Handling
