Subprocessors
The companies that help run Smile Fitter and what each one can see. Patient details go to one provider, Cloudflare. Last updated October 28, 2026.
| Provider | Location | What it does | Data it can see |
|---|---|---|---|
| Cloudflare, Inc. | United States, with a global network | Hosts Smile Fitter and its pages, stores requests and demo pages (Workers KV), runs the AI image model (Workers AI), checks for bots (Turnstile), and counts page loads without cookies (Web Analytics). | Everything patients send: the mouth close-up (processed, not stored), name, contact details, consultation details and optional smile close-ups. Turnstile sees browser and device signals only. |
| Google LLC | United States | Google Analytics on smilefitter.com marketing pages. | Page views and device details from visitors to smilefitter.com. No patient details. Google Analytics doesn't run on preview pages. |
What isn't on this list
The face detection model (Google's MediaPipe) and our fonts are hosted on our own domain, so they don't send anything to Google. The image model, FLUX.2 [klein] from Black Forest Labs, is provided to us through Cloudflare Workers AI under Cloudflare's terms; we have no direct relationship with Black Forest Labs.
Changes
Before adding a provider that receives patient details, we update this page and email practices using Smile Fitter at least 14 days ahead, as our data processing terms say.
