How My CAT Prep handles study data and analytics

My CAT Prep does not currently require an account or send the full tracker database to an application backend. Sessions, topic status, accuracy, daily plans, preferences, streak-freeze dates, and optional helpfulness feedback are stored in localStorage on the device and browser you use.

Clearing site data, browser storage, or the browser profile can remove this information. Because there is no account-based sync, it cannot automatically be restored on another device.

Google Analytics and Vercel Analytics are used to understand visits, activation, meaningful return study days, plan completion, feature usage, and technical performance. Events may include the CAT section, logging method, duration, broad lifecycle stage, inactivity bucket, and aggregate active-day counts.

Topic names, custom topic titles, session identifiers, and free-text study notes are not sent as analytics event parameters. The optional helpfulness prompt sends only a 1–5 score and a predefined reason category.

Google and Vercel may process device, browser, network, referral, and usage information according to their own services and policies. Browser privacy settings, extensions, or consent controls may limit analytics collection.

You can remove local study data by clearing storage for mycatprep.in in the browser. Google Analytics provides separate controls and browser options for limiting analytics collection.

This page reflects the current local-first product architecture and will be updated if accounts, cloud sync, or additional data processing are introduced.
