Is Buscapé safe?

Question

Is Buscapé safe?

Accepted Answer

Buscapé is medium risk. Our dynamic analysis captured POST requests confirming that the Buscapé extension derives a browser fingerprint using FingerprintJS v3 on installation and uses the resulting hash as a permanent tracking identifier. This identifier — stored as `anonymousId` in chrome.storage.local — is attached as `client_id` to every Google Analytics 4 event (install, click, page view, purchase) sent to google-analytics.com, and as `fingerprint` in lead registration calls to the Buscapé API. The ID persists indefinitely across browsing sessions and is not linked to any account action or user consent step.
