Privacy policy
Who we are
Cortex Charts makes Cortex Lens, a Chrome extension that checks Practice Fusion charts for coding problems. This policy covers cortexcharts.com and Cortex Lens.
Chart data from Cortex Lens
Lens reads the chart you have open, removes your patient’s name and record number in your browser, and sends the rest to Cortex to be checked. Our security page lists exactly what Lens reads, what it removes, where charts are checked, and what we keep.
Your account
If your practice invites you, we store your email address so you can sign in. We also keep a log of sign-ins, invitations, and role changes.
Demo requests
When you book a demo, we store what you enter in the form and email it to our team. To limit spam, we keep a scrambled version of your network address, never the address itself.
Website analytics
On our public pages, we count page views with PostHog. We don’t record sessions or track clicks.
Who helps us run the service
We use Vercel to run our website and servers, Supabase for our database, Anthropic to check charts, Resend to send email, and PostHog for page-view counts.
