2. Data collected and purposes
Sign-in via X (Twitter)
ArtMakers uses X (Twitter) exclusively for authentication. When you sign in, the following data is transmitted by X and stored: X username, display name, profile image URL, and a unique user ID. This data is required to provide the service (Art. 6(1)(b) GDPR).
User-uploaded content
Artworks and images you upload are stored on Cloudflare R2 infrastructure. Processing is carried out for the performance of the contract (Art. 6(1)(b) GDPR).
Error reporting and diagnostics
We use Sentry (Sentry Inc., USA) for quality assurance. When errors occur, technical data such as browser type, operating system, URL, and user ID may be transmitted. The legal basis is our legitimate interest in the stability of the service (Art. 6(1)(f) GDPR). Sentry is certified under the EU–US Data Privacy Framework.
Server logs and hosting
The frontend is hosted via Vercel Inc. (USA) and the backend via Railway Corp. (USA). When you access the platform, technical data (IP address, timestamp, requested URL, HTTP status codes) is automatically stored in server logs. The legal basis is our legitimate interest in secure operation (Art. 6(1)(f) GDPR). Both providers are certified under the EU–US Data Privacy Framework.
3. Disclosure to third parties
Data is only shared with the service providers listed above (X/Twitter, Cloudflare, Sentry, Vercel, Railway) as part of the respective data processing agreements. No further disclosure to third parties takes place unless we are legally required to do so.
4. Retention
User data is stored for as long as an active account exists. After account deletion, personal data is removed within 30 days unless statutory retention obligations apply. Server logs are automatically deleted after 30 days.
