• Portability: Receive your data in a machine-readable format
• Object: Object to processing based on legitimate interest
• Complaint: Lodge a complaint with supervisory authorities

To exercise these rights, contact us at johannes.schmitt@math.ethz.ch.

10. AI Model Testing

We test AI systems on mathematical questions submitted to the platform. This testing:

• Evaluates mathematical reasoning capabilities only
• Does NOT involve processing of personal data
• Does NOT profile or make automated decisions about users
• Results are used solely for academic research purposes

11. International Users

While we welcome international collaboration:

• Data is processed and stored in Switzerland
• Switzerland is recognized by the EU as providing adequate data protection
• We comply with GDPR for EU/EEA users
• Users from other jurisdictions participate under Swiss law
