Description
In what scenarios do you need this feature?
Hello,
Currently, SiYuan sync only offers two data center options:
- LianDi (China mainland)
- LiuYun (North America)
This creates significant issues for European users:
- GDPR Compliance: EU regulations require data sovereignty and explicit consent for cross-border transfers
- Performance: High latency (150ms+) from Europe to existing centers
- Enterprise Adoption: Many EU companies have policies restricting data storage outside EU
Proposed Solution
Add a third data center option: EU-Central (Frankfurt/Amsterdam)
User Interface
Data Center Selection:
○ LianDi (Asia-Pacific)
○ LiuYun (North America)
● EU-Central (Europe) [NEW]
○ Auto-detect
Key Features
- GDPR-compliant data processing
- <50ms latency for EU users
- Data migration tools between centers
- ISO 27001 certified hosting
Benefits
For Users:
- Legal compliance with EU regulations
- 3x faster sync performance
- Peace of mind for sensitive data
For SiYuan:
- Unlock EU enterprise market
- Competitive advantage vs Obsidian/Notion
- Avoid regulatory risks
Describe the optimal solution
Technical Requirements
- EU-based hosting provider (AWS/Azure/Google EU regions)
- End-to-end encryption
- GDPR audit trail
- Data export/deletion capabilities
Implementation Timeline
- Phase 1 (3-4 months): Infrastructure setup
- Phase 2 (2 months): UI development & migration tools
- Phase 3 (1-2 months): GDPR compliance & testing
Impact
This would enable SiYuan adoption by:
- EU healthcare professionals (patient data protection)
- Legal firms (attorney-client privilege)
- Educational institutions (student data protection)
- Government agencies (data sovereignty requirements)

As a lifetime subscription user based in Europe I strongly support this request

@InoPlugs If a data center is established separately, the data is completely isolated, which means that the account subscription status cannot be migrated and can only be repurchased in the new data center.
In addition, we may not be able to establish a European data center in the short term, mainly because the storage service provider we currently rely on does not have a European node. If we want to establish a European node, we need to develop and transform some of the software infrastructure services to adapt to the new provider, which will take some time.

Thank you! I hope in this case it will be possible for existing lifetime users to migrate to the new data center without repurchasing. Otherwise early adopters have a disadvantage because they couldn't select an European data center when they purchased the subscription. It should be possible to revoke the subscription and to create a new one on the European data center.
