Privacy Policy

Last Updated: April 9, 2026

Daniel Sticker ("we", "us", "our") operates Cadenza (the "Service") as a personal project. This Privacy Policy explains how we collect, use, and protect your personal data in accordance with the General Data Protection Regulation (GDPR) and applicable German data protection law.

I. Information We Collect.

When you create an account, we collect your name, email address, authentication provider (such as Google or GitHub), and account preferences. When you use the Service, we collect the inputs you submit to Cadenza, which can include LinkedIn profile URLs, notes, drafts, and chat messages. We also collect limited product-usage data needed to operate the Service, prevent abuse, understand feature usage, and improve reliability. When you contact support, we collect the messages and attachments you send.

II. How We Use Your Information.

We use your information to provide and maintain your account, power the reading and drafting workflows inside Cadenza, send transactional emails (such as verification, password reset, billing, and support replies), communicate important service updates, and improve the Service through product analytics and operational logs. We do not sell your personal data or share it with third parties for their own marketing purposes.

We process your data on the following legal bases under the GDPR: contract performance (Art. 6(1)(b)) to provide your account and the Service, legitimate interest (Art. 6(1)(f)) to improve the Service, prevent misuse, and ensure security, and consent (Art. 6(1)(a)) where explicitly required.

IV. Third-Party Processors.

We use the following third-party services to operate the Service: Convex for database and backend infrastructure, the configured hosting provider for application delivery, Resend for transactional email delivery, PostHog for product analytics, OpenRouter for AI model access, and Tolgee for localization workflows. These providers process personal data only to the extent needed to provide their services to us.

V. Cookies.

We use essential cookies required for authentication, session management, localization, and security. We may also use privacy-respecting analytics cookies or equivalent storage where permitted by law and configured on the Service. We do not use the Service to serve advertising.

VI. Data Retention.

We retain your personal data for as long as your account is active or as needed to provide the Service. When you delete your account, we will delete or anonymize your personal data unless retention is required by law, needed for security investigations, or necessary to resolve disputes or enforce our agreements.

VII. Your Rights.

Under the GDPR, you have the right to access your personal data (Art. 15), rectify inaccurate data (Art. 16), request deletion of your data (Art. 17), restrict processing (Art. 18), data portability (Art. 20), and object to processing (Art. 21). To exercise any of these rights, please contact us using the details below. You also have the right to lodge a complaint with a supervisory authority.

VIII. Changes to This Policy.

We may update this Privacy Policy from time to time. If we do, we will post the updated version on this page and update the "Last Updated" date above. Material changes will take effect when posted unless a longer notice period is required by law.
