Data privacy compliance is no longer just a legal team problem. Developers and engineers are now on the front line. The systems you build decide whether a company stays compliant or faces heavy fines.
China's Data Privacy 2.0, fully enforced from January 2026, sets clear technical requirements for how personal data must be collected, stored, and transferred. If you build apps, APIs, or SaaS products that touch Chinese user data, this affects your architecture.
What the Law Actually Requires from Your Systems
Under PIPL, consent must be captured at a granular level. That means your system needs to record what a user consented to, when they consented, and for which specific data processing activity. A single checkbox is not enough.
For cross-border data transfers, your systems must support one of three legal pathways: a CAC Security Assessment, Standard Contractual Clauses, or a Personal Information Export Certification. Each requires your consent records to be linked to specific transfer events.
Key Technical Requirements to Build For
Your consent system must log timestamps and user identifiers for each consent event. Withdrawal must be handled in real time, with data processing stopping immediately after a user opts out. Consent records must be auditable and retrievable on demand.
If you use third-party SDKs or analytics libraries that transfer data internationally, those transfers also need documented consent. This includes most major ad tech and analytics platforms.
How to Avoid Common Compliance Failures
Most enforcement actions in 2026 target apps and SaaS products with weak or missing consent flows. Regulators check whether consent is truly informed, whether withdrawal works as promised, and whether logs are complete.
Using a purpose-built consent management solution like Seers AI removes the need to build consent infrastructure from scratch. It provides APIs for consent capture, a dashboard for audit logs, and cross-region management out of the box.

Build Privacy In, Not On
Retrofitting compliance is expensive. Build your data collection and storage systems with privacy controls from the start. It is faster, cheaper, and keeps your product audit-ready as laws continue to evolve.
