The diagnostic tools (LandingPageDx, EmailDx, DirectMailDx)
What gets captured
When you submit your email to see a full report, JulieDx stores your email address, which tool you ran, the date, and a run counter. That’s it. The data lives in an Airtable base I (Julie) own and look at.
When you subscribe
If you create an account or start a subscription, JulieDx stores your account email (via Clerk, the login provider) and a Stripe customer reference to manage billing and your access. Your run history stays a simple counter.
What does NOT get captured
The content you submit - email copy, landing page URLs, direct mail files, screenshots - plus the diagnostic responses and your follow-up questions, are processed by Anthropic’s API and never stored by JulieDx. I don’t log them, save them, or look at them.
Third parties that see your input
Your inputs are sent to Anthropic (the company that makes Claude, the AI model behind the tool) to generate the diagnostic. Their privacy policy is at anthropic.com/legal/privacy.
When you submit a URL for LandingPageDx, the URL is sent to Jina.ai (a free page-reader service) to extract page text. Their privacy policy is at jina.ai/legal.
Cookies and local storage
JulieDx uses browser localStorage to track your free run and remember your email so you don’t have to type it again. If you sign in or subscribe, the login provider (Clerk) sets a session cookie to keep you logged in. No third-party ad trackers, no Meta Pixel.
Third parties for accounts and billing
If you create an account or subscribe: Clerk handles login and stores your account identity. Their privacy policy is at clerk.com/legal/privacy. Stripeprocesses your payment; I don’t see or store your card details. Their privacy policy is at stripe.com/privacy.
JulieDx Job Search (paid tool)
What gets captured
When you run the Job Search tool, JulieDx stores: your LinkedIn account identity (name and email, from Sign in with LinkedIn - for account management only), your profile grade and keyword coverage score, and the job titles you search against. That’s it.
What does NOT get captured
Your profile text and full job description text are processed to generate your results and never stored by JulieDx.
How the stored data is used
Grade, score, and job title data are stored in anonymized, aggregated form. This is used to calculate benchmarks (e.g., “your profile grades better than X% of profiles we’ve graded”), improve the tool’s keyword coverage over time, and understand which roles people are searching for. This data is never sold or shared with third parties.
Third parties for the paid tool
In addition to Anthropic (above): LinkedIn is used for login and identity only - it returns your name, email, and LinkedIn ID. It does not return your profile content, and JulieDx does not pull your profile data via the API. Their privacy policy is at linkedin.com/legal/privacy-policy. Stripe processes your payment. I don’t see or store your card details. Their privacy policy is at stripe.com/privacy.
Your data, your call
Email julie@juliedx.com and I’ll delete your data. No questions, no forms.
Analytics
JulieDx uses PostHog to understand how the tools are used in aggregate (page views, run counts, conversion) and Microsoft Clarity for session behavior analysis (scroll depth, click patterns, no recordings of form inputs). No ad targeting. No third-party data sharing.
Changes to this policy
If anything changes - new feature, new third party - I’ll update this page and bump the date at the top.
