You choose the optional part.
No advertising trackers. Optional first-party measurement is off by default.

Essential storage
A local browser preference records the analytics choice. Form confirmation state and sandbox interactions are not advertising profiles. The public demo does not send sandbox lead contents to a CRM.
Optional measurement
With consent, the browser may send an allowlisted action name and public context to a configured first-party aggregate endpoint. No name, email, message or URL query string belongs in that event.
Change your mind
Use the privacy control to allow or deny future optional measurement. The choice applies to this browser; clearing storage removes it. Hosted spam checks, if enabled, require review against the actual provider configuration.
