Cookie Policy
Last Updated: June 15, 2026
1. What Are Cookies and Why We Use Them
Cookies are small text files stored on your computer or mobile device when you visit websites. At Pathurn and Clerkyn, we use cookies, local storage keys, and browser cache structures to authenticate your account, maintain active study dashboard states, analyze traffic, and improve the responsiveness of our virtual slide viewers and clinical simulation desks.
To guarantee maximum clarity, Pathurn and Clerkyn maintain separate cookie contexts for our public landing pages (which utilize tracking consent modules) and our high-fidelity dashboards (where cookies are strictly operational or analytical for security audits).
2. Cookie Classification
We separate cookies into functional categories. Essential cookies cannot be disabled as they are required to secure the site and verify user logins.
Essential (Strictly Necessary)
Required to authenticate user sessions via Appwrite across both pathurn.study and clerkyn.pathurn.study domains, process checkout tokens safely via Flutterwave, and manage basic security contexts.
Analytics & Experience
Allow us to track UI hot-spots, page latency, and system response times via PostHog and Microsoft Clarity to eliminate visual glitches.
Preferences & Functionality
Retain dashboard choices, custom sidebar layout states, and your muted/unmuted settings for study simulators.
Marketing & Updates
Help us deliver product updates and notifications regarding new pathology specimen batches and clinical scenarios to registered users.

4. Managing Preferences & Consent
When you first visit our landing pages, a consent banner is displayed. You can choose to accept all cookies, opt-out of non-essential analytics cookies, or manage granular settings.
If you wish to clear or reject cookies globally, you can adjust your browser settings. Be advised that blocking essential cookies will break active session authentication, and you will be unable to log into the Pathurn or Clerkyn dashboards.
