Privacy Policy
Version 1.3 — effective from May 19, 2026
1. Controller
Thorsten Ahrens Zillestr. 75 51067 Cologne, Germany Email: contact@kineangst.de
No data protection officer has been appointed pursuant to Art. 37 GDPR; the thresholds requiring such an appointment are not met.
2. Data Collection on This Website
a) Contact Requests via Email
When you contact us by email, the data you provide (your email address, possibly your name and your message) will be stored to process your inquiry. Legal basis: Art. 6(1)(b) GDPR (pre-contractual measures) and Art. 6(1)(f) GDPR (legitimate interest in responding to inquiries).
b) User Account
Upon registration, your name and email address are stored. Authentication is handled via Supabase (password or magic link). Legal basis: Art. 6(1)(b) GDPR (performance of a contract).
c) Experience Points (XP System)
For logged-in users, interactions (articles read, tests completed, content shared) are recorded in a points system. Purpose: gamification and progress tracking. Data stored: user_id, action, reference, timestamp. Legal basis: Art. 6(1)(b) GDPR (performance of a contract). XP data is used solely for progress display within the user's own account — no profiling, no advertising, no transfer to third parties.
d) Anonymous Test Statistics
Upon completion of the AI Anxiety Test, dimension scores are saved without any user reference and without IP address. Purpose: anonymous community comparison (only displayed once at least 10 participants). This data cannot be traced back to individual persons. Legal basis: Art. 6(1)(f) GDPR (legitimate interest).
3. Legal Basis
Data processing is carried out on the basis of:
- Art. 6(1)(a) GDPR (consent) — for newsletter subscription.
- Art. 6(1)(b) GDPR (performance of a contract) — for user accounts, XP system, contact requests.
- Art. 6(1)(c) GDPR (legal obligation) — for disclosure to law enforcement authorities.
- Art. 6(1)(f) GDPR (legitimate interest) — for anonymous test statistics, hosting logs, and web analytics.
4. Data Retention
- Server logs (Vercel): up to 30 days.
- Contact requests: Deleted as soon as they are no longer necessary for the purpose for which they were collected and no statutory retention obligations apply.
- Account data (name, email): Until deletion of the user account. Accounts inactive for more than 24 months are deleted together with the associated data after a prior notification e-mail.
- XP data: Until deletion of the user account.
- Anonymous test statistics: Indefinitely, as they are not personal data.
- Newsletter consent: Until revocation; after revocation the e-mail address is deleted from the distribution list (no suppression list is maintained).
5. Hosting
This website is hosted by Vercel Inc. (USA). When you visit, technical data (IP address, browser type, operating system, referrer URL, access time) is automatically recorded in server logs. Processing is carried out on the basis of Art. 6(1)(f) GDPR (legitimate interest in the secure and stable provision of the website and in defending against attacks). In the balancing of interests, the controller's interests prevail because the processing is limited to what is technically necessary, no profiles are created, and logs are automatically deleted after 30 days.
