China Privacy Law Sensitive personal information and separate consent under PIPL
How to identify sensitive PI triggers, separate consent, minors, additional safeguards, and evidence records.
Classify by the harm test in Article 28, not only by a field name. Sensitive processing needs a specific purpose, sufficient necessity, strict protection, additional notice, separate consent, and a prior impact assessment.

Sensitive personal information under PIPL is information that, if leaked or illegally used, could readily infringe a person's dignity or endanger personal or property safety. Article 28 lists biometrics, religious belief, specific identity, medical and health information, financial accounts, location traces, and all personal information of children under 14. Process it only for a specific purpose with sufficient necessity and strict protection measures, and complete the additional notice, separate-consent, and impact-assessment steps required by Articles 29, 30, and 55.
1. Classify the information and the processing context
Use both the statutory examples and the harm test. A field label alone may be too broad or too narrow: assess what the data reveals, the precision and scale, whether it is combined with other information, who can access it, and the likely result of leakage or illegal use. Record the field-level rationale and the data flow.
All personal information of a child under 14 receives sensitive-personal-information treatment, regardless of whether an adult's equivalent field would otherwise be sensitive. Verify age and guardian flows without collecting more information than the purpose requires.
- Specific identity can include information that reveals a status or identity with the Article 28 harm potential; do not treat every ordinary identifier as sensitive without applying the test.
- Location traces are different from a one-off coarse location in some contexts, but precise or combined location data may still meet the harm test. Document the actual precision, frequency, duration, and use.
- Derived or inferred information can be sensitive when it reveals health, religion, identity, finances, movements, or another condition meeting Article 28.
- A separate legal or administrative rule may require written consent, an administrative authorization, or another restriction in addition to PIPL.
2. Complete the notice and consent steps
Before processing, give the ordinary Article 17 notice and also explain why processing the sensitive personal information is necessary and how it affects individual rights, unless a PIPL notice exception applies. Article 29 requires separate consent; if a law or administrative regulation requires written consent, follow that form.
- Keep the sensitive purpose separate enough for the person to make a clear choice; do not hide it in a general privacy-policy acceptance or bundle unrelated sensitive purposes together.
- Record the notice version, language, presentation, purpose, categories, method, retention, recipient information where applicable, necessity and impact explanation, consent action, timestamp, withdrawal, and processing status.
- Make withdrawal convenient where processing is based on consent. Withdrawal does not affect processing completed before withdrawal, but it should stop future consent-based processing unless another lawful ground applies.
- For a child under 14, obtain consent from a parent or other guardian and adopt dedicated personal information processing rules.
- Provision to another personal information processor and overseas provision have their own notice and separate-consent duties in Articles 23 and 39; a sensitive-information consent record should not silently stand in for those distinct decisions.
3. Prove necessity, protection, and ongoing control
Complete a personal information protection impact assessment before processing. It must assess legality, legitimacy, and necessity; effects on individual rights and security risks; and whether safeguards are lawful, effective, and proportionate. Keep the report and processing record for at least three years.
- Necessity record: identify the specific purpose, why less sensitive or less precise information will not work, the minimum people and systems with access, and the shortest necessary retention period.
- Strict-protection record: map access restrictions, encryption or de-identification where appropriate, logging, monitoring, transfer controls, recipient or vendor safeguards, incident response, deletion, and control owners to the assessed risks.
- Implementation evidence: retain configuration, access review, test results, notice and consent records, vendor terms, recipient checks, deletion evidence, incident exercises, and approval conditions.
- Change trigger: reassess classification, necessity, notice, consent, and safeguards before changing purpose, category, precision, scale, source, recipient, vendor, access location, retention, or affected group.
- If the purpose cannot justify sufficient necessity, or the safeguards do not match the risk, do not begin or continue the sensitive processing.
