What is the purpose of TEST-COOKIE?
The TEST-COOKIE cookie is a third-party tracking cookie set by InMobi, a mobile advertising and programmatic platform. The cookie functions as a diagnostic tool that tests whether the user's web browser is configured to accept cookies. Before deploying other persistent identifiers for ad targeting or cross-site tracking, the platform drops this temporary test cookie; if it can be successfully read back, the system confirms that cookie storage is supported on the client side.
Although it is technically a diagnostic cookie with a static value, it is set in the context of InMobi's advertising infrastructure (including cookie-syncing via sync.inmobi.com) to facilitate targeted ads, frequency capping, and audience measurement. Because it operates within an advertising ecosystem to enable subsequent behavioral tracking, it is routinely classified under targeting and advertising consent categories.
What are the Privacy Risks of TEST-COOKIE?
Risk Level: Low
Although this cookie is set by a third-party advertising network (InMobi), the risk level is assessed as Low because the cookie itself only stores a static value (such as "YES") to verify whether the browser supports cookies. It does not store pseudonymous identifiers, track behavioral patterns, or collect Personally Identifiable Information (PII).
How to Remove TEST-COOKIE from a Website
To stop this cookie from being set, website administrators must remove the InMobi tags, scripts, or SDKs from the website's source code or tag management system. Because this cookie is an inherent part of InMobi's ad-serving and cookie-checking process, it cannot be disabled independently from the service itself. To eliminate the cookie, the site operator must discontinue the use of InMobi's advertising services by completely removing its integration.
