Shein generates and stores a unique identifier for your browser session, called a 'cookieId' or 'OEST' token, which persists in both cookies and localStorage to track you across visits.
This analysis describes what Shein's agreement states, permits, or reserves. It does not constitute a legal determination about enforceability. Regulatory applicability and practical outcomes may vary by jurisdiction, enforcement context, and individual circumstances. Read our methodology
This persistent cross-session identifier enables Shein to link your browsing activity across multiple visits, which may constitute personal information under privacy laws and requires disclosure and, in some jurisdictions, consent.
Interpretive note: The full scope of data associated with the OEST identifier and its retention or deletion upon consent withdrawal cannot be determined from the document source alone.
Previously, Shein asked users to explicitly agree or disagree with account persistence for future logins. The updated terms remove this choice entirely. Instead of a consent decision, users now see a promotional discount offer in that location. This means users lose direct control over whether Shein maintains their login session across device visits, which affects convenience and privacy preferences around authentication persistence.
View change record →Removal of explicit base64-decoded cookieId variable initialization may indicate refactoring of session identifier generation, though OEST functionality continues in modified form.

How other platforms handle this
If you choose to reveal any personal information about yourself to other users, you do so at your own risk. We strongly encourage you to use caution in disclosing any personal information online.
When you are asked to provide information, you may decline to do so; but if you choose not to provide information that is necessary to provide some of our Services, you may not be able to use those Services.
