1. Controller

This website is operated by Viktor Schöne. For privacy-related questions, contact team@comstein.com.

2. Data We Collect

Depending on how you use comstein, we may process account details such as name, email address, password-authentication data handled by our authentication provider, role and profile details, product and application content, support messages, usage and log information, and technical data such as IP address, browser details, and essential session or security cookie data.

3. Why We Process Data

We process personal data to create and manage accounts, operate the marketplace, match founders with partners or agents, provide dashboards, secure the service, investigate abuse, respond to support requests, comply with legal obligations, and improve the stability and performance of the platform.

4. Legal Bases

We generally rely on contract performance to provide the service you request, legitimate interests to secure and improve the platform, legal obligations where records or compliance are required, and consent where a specific processing activity legally requires it.

5. Service Providers and Recipients

We use third-party providers that help us run the platform, including infrastructure and content delivery providers, database and authentication providers, and payment providers where payment-related features are used. Based on the current service setup, this may include Cloudflare for hosting and delivery, Supabase for authentication and database services, and Stripe for payment-related processing where relevant.

6. International Transfers

Some service providers may process data outside your country. Where personal data is transferred internationally, we rely on appropriate safeguards required under applicable law.

7. Retention

We keep personal data only for as long as needed for the purposes described in this policy, including account operation, security, support, contractual records, and legal compliance. Retention periods may vary depending on the data type and applicable obligations.

8. Your Rights

Subject to applicable law, you may request access to your personal data, correction, deletion, restriction of processing, data portability, or objection to certain processing. You may also lodge a complaint with a competent supervisory authority.

9. Cookies and Similar Technologies

comstein uses essential cookies and similar technologies that are necessary to keep you signed in, protect the service, and support core functionality. If optional tracking or marketing technologies are added later, we will present any required notices or choices separately.
