FAQ

Is this legal advice?

No. It is an implementation guide. For unusual data flows, confirm the setup with your legal or privacy team.

Does CookiePilot block every script automatically?

CookiePilot supports autoblocking and Consent Mode. Trackers hardcoded before the CMP still need to be moved behind the stub or into GTM Consent Initialization.
