Privacy Policy

This policy explains what personal data is processed when you use ARKANUM and for what purpose.

1. Data Controller

Christian Wagner
Schlesienstraße 4b, 24558 Henstedt-Ulzburg, Germany
Email: cwagner372@gmail.com

2. Data We Process

• Account data: your email address and an encrypted password (stored via our authentication provider).
• Patreon connection (optional): when you connect your Patreon account, your Patreon user ID, membership status, unlocked tiers, and OAuth access token — solely to verify your access to gated modules.
• Usage data: download events (module, version, timestamp) and a technically necessary session cookie for sign-in.
• Analytics data: aggregated, cookieless usage and performance metrics (see section 5).

3. Purposes and Legal Basis

Processing serves to provide the platform, handle authentication, and control access to paid or member-exclusive content. The legal basis is the performance of the usage agreement (Art. 6(1)(b) GDPR) and our legitimate interest in operating a secure, functional service (Art. 6(1)(f) GDPR).

4. Service Providers

We use the following service providers to operate the platform:

• Supabase — database, authentication, and file storage (hosting account and module data).
• Vercel — website hosting and delivery, as well as privacy-friendly, cookieless usage and performance analytics (see section 5).
• Patreon — only when actively connected: verifying your membership and tier status.
• GitHub — server-side retrieval of module releases; no personal user data is transmitted in the process.

5. Analytics

We use Vercel Web Analytics and Vercel Speed Insights to understand how the site is used and to monitor loading performance. These tools work without cookies and do not store any identifiers on your device. They collect aggregated, anonymized information such as visited pages, referrer, approximate device type, and technical performance values (Web Vitals). No cross-site tracking, profiling, or advertising analysis takes place, and individual visitors are not identified. The legal basis is our legitimate interest in a functional, performant website (Art. 6(1)(f) GDPR).

6. International Data Transfers

Some of our service providers (in particular Vercel) are based in the United States or may process data there. Where personal data is transferred to a third country, this is safeguarded by appropriate measures such as the EU Standard Contractual Clauses and, where applicable, certification under the EU–U.S. Data Privacy Framework.

7. Retention

Account and connection data is stored for as long as your account exists. Upon request or deletion of your account, the associated data will be deleted, unless statutory retention obligations apply.

8. Your Rights

You have the right to access, rectification, erasure, restriction of processing, data portability, and objection. You may also lodge a complaint with the competent data protection supervisory authority. Please use the contact address above.

9. Cookies & Local Storage

We use only technically necessary cookies for the sign-in session and CSRF protection during the Patreon connection. We also store your selected colour theme locally in your browser (local storage) so the site remembers your preference. Apart from the cookieless analytics described in section 5, no advertising or cross-site tracking takes place.
