4. Purposes of Processing and Legal Basis

We process your personal data for the following purposes, based on the legal grounds listed:

4.1 Service Provision (Legal Basis: Contract Performance)

  • Creating and managing your user account
  • Providing access to our platform and mobile app
  • Enabling project and task management functionality
  • Facilitating team collaboration and communication
  • Processing and storing your documents and files
  • Delivering requested features and services

4.7 AI and Intelligent Features (Legal Basis: Legitimate Interest & Consent)

  • Document OCR processing using Mistral OCR (EU-based provider, France) for text extraction from uploaded documents (users can review and correct extracted data)
  • NeKo-Check AI-powered document analysis: Analysis of rental agreements and utility bills using Mistral OCR (text extraction, EU-based provider in France) and Anthropic Claude via AWS Bedrock (intelligent content analysis, EU inference profiles, region eu-central-1 Frankfurt). Document contents may naturally contain personal data (e.g., names, addresses). This data is processed solely for analysis, not stored, and not used to train AI models.
  • Generation of clarification questions, warnings, and recommendations based on document analysis

Note on Automated Decision-Making (Art. 22 GDPR): Our AI-powered analyses (particularly NeKo-Check) are purely advisory in nature and do not produce decisions with legal or similarly significant effects. The results serve as guidance and orientation — the final assessment and decision always rests with the user. Art. 22(1) GDPR therefore does not apply.


5. Data Sharing and Third-Party Processors

We share your personal data only with trusted third-party service providers who help us operate our platform. All processors are bound by data processing agreements and comply with GDPR requirements.

5.1 Self-Hosted Infrastructure (Hetzner Falkenstein, Germany)

All application services, databases, identity management, secrets management, observability, messaging, and web hosting run on self-managed Kubernetes ("Aether") on 8 dedicated bare-metal servers in Hetzner's Falkenstein datacenter (Germany). Data resides in Falkenstein, Germany. Encryption: WireGuard for node-to-node, TLS for application traffic, encryption at rest for PostgreSQL.

5.6 AI Service Providers

Anthropic Claude (via AWS Bedrock): AI-powered document analysis. Hosting: AWS eu-central-1 (Frankfurt, Germany). Data is not stored or used to train AI models.

Mistral AI (OCR): Hosted in Paris, France. Documents processed solely for text extraction; not stored or used to train AI models.


6. Data Retention

  • User Profile and Account Information: Retained while your account is active
  • Project and Task Data: Retained while projects are active, plus 3 years after project completion
  • Audit Logs: Retained for 7 years for legal compliance and security purposes
  • Financial Records: Retained for 10 years in accordance with tax and accounting regulations
  • Account Deletion: Personal data deleted within 30 days; backups up to 90 days; audit logs retained pseudonymized.

7. Your Rights Under GDPR

As an EU resident, you have the following rights regarding your personal data:

  • Right of Access (Art. 15 GDPR)
  • Right to Rectification (Art. 16 GDPR)
  • Right to Erasure / "Right to be Forgotten" (Art. 17 GDPR)

8. Cookies and Tracking

Our public website is a static site with minimal cookie usage. We do not use analytics, advertising, or tracking cookies on the public website. User preferences are stored in browser local storage.

Internal applications use ASP.NET Core authentication cookies, anti-forgery tokens, and session cookies — strictly necessary for service operation under GDPR Article 6(1)(b).

Plausible Analytics (self-hosted): No cookies, no IP addresses, no fingerprinting. Daily-rotating hash held only in memory.


9. International Data Transfers

Your personal data is stored and processed exclusively within the European Union. The vast majority of data never leaves Germany. Limited transfers occur for AI inference (AWS eu-central-1 Frankfurt; Mistral AI France) — both bound by EU Standard Contractual Clauses with no persistent storage and no training use.


10. Security Measures

  • Encryption of data in transit and at rest
  • Access controls and authentication, including multi-factor authentication
  • Regular security reviews and vulnerability assessments
  • Data protection training for all staff and confidentiality agreements
  • Regular data backups

Data Breach Notification: In the event of a personal data breach posing a risk to your rights and freedoms, we will notify the competent supervisory authority within 72 hours (Art. 33 GDPR) and affected individuals where the breach is likely to result in a high risk (Art. 34 GDPR).


11. Children's Privacy

Our services are not intended for individuals under the age of 16. We do not knowingly collect personal data from children under 16. If you believe we have collected information from a child under 16, please contact info@aquilo-solutions.com.
