Last updated: January 8, 2026

1. Introduction

Cadenza ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use our AI-powered writing assistant.

2. Information We Collect

2.1 Content You Create

When you use Cadenza, we process the text you write to provide AI-powered suggestions. By default, your documents are stored locally in your browser and are not transmitted to our servers except when generating suggestions.

2.2 Account Information

If you create an account for cloud sync, we collect your email address and store your documents securely in our cloud database.

2.3 Usage Data

We may collect anonymous usage statistics to improve our service, including feature usage patterns and performance metrics. This data does not include the content of your documents.

3. How We Use Your Information

  • To provide AI-powered writing suggestions
  • To sync your documents across devices (if you opt in)
  • To improve and optimize our service
  • To communicate important updates about the service

4. Third-Party Services

Cadenza uses Anthropic's Claude AI to generate writing suggestions. Text you write is sent to Anthropic's API for processing. Please review Anthropic's privacy policy for information about how they handle data.

If you use cloud sync, your data is stored using Supabase, a secure database platform. Data is encrypted at rest and in transit.

5. Data Security

We implement appropriate security measures to protect your data, including:

  • Encryption of data in transit (HTTPS)
  • Encryption of data at rest in our cloud database
  • Row-level security policies to ensure you can only access your own data
  • Regular security audits and updates

6. Your Rights

You have the right to:

  • Access your personal data
  • Delete your account and all associated data
  • Export your documents
  • Opt out of cloud sync and use Cadenza locally only

7. Data Retention

Local data is stored in your browser until you clear it. Cloud-synced data is retained until you delete your account. We do not retain copies of text sent to the AI for suggestion generation.

8. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new policy on this page and updating the "Last updated" date.
