Study data and sign-in
V2 stores account-linked study evidence, sessions, assessments, goals, plans, and preparation history in Neon Postgres. This evidence powers recommendations and progress views. Clerk manages sign-in, including Google authentication; the application maps that identity to an internal user ID.
Anonymous onboarding uses a short-lived encrypted, HttpOnly cookie to hold your plan preview. Saving study work requires sign-in. Clearing browser storage does not delete study work already saved on the server.
Previous browser-only study data
The retired v1 tracker stored study data in localStorage. Visit /app in the same browser and on the same mycatprep.in origin to download an archive of that data. The export is created on your device and does not upload or delete the stored values.
The archive is not automatically imported into v2. Clearing site data, switching browsers, or removing a browser profile can make previous browser-only data unavailable.
Analytics and performance
The site uses Google Analytics for production visits and marketing button interactions, plus Vercel Analytics and Speed Insights for usage and performance measurement. Marketing button events include the source page and button placement; the archive export does not send study values to analytics.
These providers may process device, browser, network, referral, and usage information under their own privacy policies. Authentication and study records are separate from marketing event parameters.
Service providers
Vercel hosts the application, Neon stores application records, and Clerk handles authentication. Google processes Google sign-in and Google Analytics information for their respective purposes. Study work is processed on the server to provide the account and recommendation features.
Managing your data
You can sign out to end access on a shared device. Browser controls can clear cookies and previous local tracker data, but do not delete your server-side study records or your account. Download any previous tracker archive before clearing local storage.
V2 does not currently provide an account-wide export or deletion interface. The /app download covers only previous browser-stored tracker data. Browser privacy controls can limit analytics collection.
Policy updates
This page describes the v2 architecture and will be updated when storage, authentication, or analytics behavior changes.
