Privacy Policy
Effective Date: November 2026
ZiyuanLingo ("we", "our", or "us") operates https://ziyuanlingo.com and the ZiyuanLingo Web Studio SaaS platform. We are committed to protecting the confidentiality of your manuscripts, legal documents, and personal data.
1. Information We Collect
- Account & Billing Data: Work email address, subscription tier, and payment metadata processed securely through PCI-compliant payment providers.
- Uploaded Document Content: Source files, custom glossaries, and generated translations submitted for processing within your workspace.
- Operational Telemetry: Request latency, token consumption metrics, and error diagnostics required to maintain service reliability.
2. Zero Model-Training Guarantee & Data Security
We never use customer manuscripts, glossaries, or translated outputs to train or fine-tune foundation AI models. All data transmitted between your browser, our cloud workers, and Google Cloud Vertex AI APIs is encrypted via TLS 1.3 in transit and AES-256 at rest. Users may permanently purge project state snapshots at any time.
3. Subprocessors
We utilize enterprise cloud infrastructure providers—primarily Google Cloud Platform (Vertex AI, Cloud Run, Cloud Storage) and Cloudflare—under strict data processing addenda.
