WeChat & GDPR 2026 โ€” what EU companies actually need to do

ยท 2 min read

WeChat is not a โ€œshadow IT exceptionโ€. The moment you use it in B2B sales, you need the same building blocks as for email: lawful basis, records of processing, retention/deletion, and for Tencent infrastructure a third-country transfer assessment.

Data you actually processโ€‹

  1. Identity & contact data โ€” personal data.
  2. Conversation content โ€” often sensitive; watch special category triggers (Art. 9 GDPR).
  3. Metadata โ€” timestamps/devices are personal data too.

Lawful bases (short)โ€‹

  • Art. 6(1)(b) โ€” contract / pre-contract when the lead actively requests evaluation or pricing.
  • Art. 6(1)(f) โ€” legitimate interest (e.g. warm outbound) only with a documented balancing test.
  • Art. 6(1)(a) โ€” consent for newsletters, retargeting, broad marketing automation.

Third countries & Schrems IIโ€‹

Tencent operates outside the EU. In practice you want:

  • EU-side processing for translation, scoring and CRM notes โ€” where you control subprocessors and DPAs.
  • Data minimisation at ingress.
  • Written retention (e.g. 24 months after last meaningful contact) enforced in tooling, not โ€œwhen someone asksโ€.

Three audit traps we see constantlyโ€‹

  1. No DPA with the CRM vendor (and bridge vendor if applicable).
  2. WeChat IDs only on private phones โ€” no corporate access for DSARs or investigations.
  3. No retention policy โ€” โ€œwe delete if askedโ€ is not a retention policy.

Bottom lineโ€‹

WeChat in the EU is allowed when done deliberately: EU-hosted processing chain, documented lawful basis, retention and subprocessors under control. That is both defensible in an audit and faster for sales than ad-hoc screenshots.
