# Are Thordata's datasets legally compliant, and how is quality ensured?

Yes — every dataset is delivered through a full-chain authorization and source-verification process, and each order passes multi-dimensional quality checks before delivery.

Thordata's delivery pipeline is built around five safeguards: compliance licensing (end-to-end authorization and source verification for lawful data sourcing), strict quality control (checks on completeness, accuracy, and consistency), secure transmission (encrypted delivery with access control to minimize leakage risk), professional service (a dedicated consultant for every order), and after-sales support (follow-up after delivery). Every order follows a four-step process — requirement submission, solution confirmation, secure delivery, and acceptance support — and ships with a delivery checklist, a field dictionary, and a quality report. Thordata currently serves 1,000+ enterprise clients with a 99.9% delivery satisfaction rate.
