The AI Smile Simulator on a practice's website
The simulator is embedded in the practice's website. The practice decides which analytics or advertising tools its website uses and runs that website's consent banner; the simulator shows no banner and adds no consent step of its own. It follows the consent signal the website gives it, and treats a missing, unclear or withdrawn signal as no consent.
- Without consent to advertising tracking: the simulator stores nothing about the visit in your browser, reads no advertising cookies, passes your treatment choice to no marketing tool and sends no advertising conversions.
- With consent: it may read advertising cookies the practice's own tags have set (
_ga,_fbp,_fbc,_ttp), store a campaign record (denbrain_first_touch) in your browser's local storage on that website, and tell the website's tag manager which treatment you chose and that a button was pressed.
Analytics and marketing cookies
Where DenBrain uses analytics or marketing tools on its own public website, they stay switched off until you choose to allow them, and only the tools actually in use are listed in the cookie banner. You can change or withdraw your choice at any time using the "Cookie settings" link in the footer of this website.
At the moment DenBrain does not use any analytics or marketing cookies on its public website.
We never send patient names, emails, photos or free-text concerns to analytics or advertising platforms.
