General & Enterprise Inquiries
If you have questions regarding Sino Mobile, Sino Desktop (Compose Multiplatform), enterprise multi-vault deployment, or feature requests, contact our team directly.
Because Sino is zero-knowledge and hardware-anchored, we have no access to your master keys, encrypted databases, or remote cloud vaults. We cannot reset master passcodes or recover lost 24-word recovery seeds.
