Frequently Asked Questions
Compliance & Data Sovereignty
For enterprises operating under GDPR, HIPAA, or CCPA, data egress is a major liability. noserver eliminates this risk entirely by keeping the processing logic client-side.
- Audit Trail Friendly: Since no third-party server is involved, you don't need to log this tool as a data processor in your compliance audits.
- Zero Retention: We cannot delete what we never had. Once you close the tab, not a single byte of your customer data remains in our possession.
- Air-Gapped Usage: The tool works 100% offline. For maximum security, you can even disconnect your internet before loading your sensitive datasets.
