Privacy Policy

Last updated: March 2026

What We Collect

When you use Notz, we collect the following information:

• Account information — your email address and display name when you register.
• Your content — journal entries, notes, tasks, and AI conversations you create within the app.
• Analytics — anonymous session identifiers to understand how the app is used. We do not track you across sites or sell this data.
• Billing information — if you subscribe to a paid plan, payment details are collected and processed by Stripe. We do not store your card number.

How We Use Your Data

• Service delivery — to provide, maintain, and improve Notz.
• AI processing — your content is sent to Anthropic's Claude API to power AI features like task extraction, journaling prompts, and chat. Anthropic does not use your data to train models.
• Billing — to process payments and manage your subscription through Stripe.
• Analytics — to understand usage patterns and improve the product. Analytics are anonymous and session-based.

Third-Party Services

We use the following third-party services to operate Notz:

• Anthropic — AI processing for journal analysis, task extraction, and chat features.
• Stripe — payment processing for paid subscriptions.
• Fly.io — application hosting and infrastructure.

Each service has its own privacy policy governing how they handle data.

Data Storage and Security

We take reasonable measures to protect your data:

• All connections use HTTPS encryption in transit.
• Authentication uses JWT tokens with secure cookie storage.
• CSRF protection is enforced on all web requests.
• Rate limiting protects against abuse on authentication, AI, and account endpoints.
• Data is encrypted at rest on our hosting infrastructure.

Your Rights

You have the right to:

• Export your data — download your journal entries and notes in JSON or CSV format from your account settings.
• Delete your account — permanently remove your account and all associated data from your account settings.
• Request data removal — contact us to request deletion of specific data or your entire account.

Cookies

Notz uses a minimal number of cookies:

• Authentication cookies — to keep you signed in across sessions.
• Analytics session ID — an anonymous identifier for usage analytics. No third-party tracking cookies are used.

Changes to This Policy

We may update this privacy policy from time to time. If we make significant changes, we will notify you through the app or by email. Continued use of Notz after changes constitutes acceptance of the updated policy.
