Your practice stays on your device
Answers, scores, settings and reports are stored in your browser. An unfinished quiz stays in its tab. No account or server synchronization is needed. The reset button on the Progress page removes saved practice; clearing this site’s browser data also removes it.
Optional analytics
With your permission, PostHog receives a random browser identifier, visited pages and screens, language, a broad device category, quiz starts and completions, learning interactions and audio failures. Quiz events include a random practice-run identifier and limited settings. We do not send answers, scores, names, or audio or video recordings. Automatic tracking, session recordings and person profiles are disabled.
Your choice is remembered for 180 days. Decline or withdraw through Privacy settings at the bottom of every page. Withdrawal stops future events and removes the local identifier without erasing practice. It does not automatically delete events already received by PostHog. Different browsers, devices or choices can be counted separately: these statistics are not an exact count of people.
The provider necessarily receives network information when a connection is made. The project uses PostHog Cloud in the United States, so analytics may be processed outside your country. The current Pay-as-you-go plan provides seven-year event retention. A plan change can change that period. The project is configured to discard IP addresses from stored events. PostHog privacy policy.
Hosting and tips
Vercel hosts the site and may process technical logs, including IP addresses, to serve and secure requests. Optional tip links open Stripe, which handles payment under its own policy. This application does not receive your card details. Returning to a thank-you page does not verify a payment. Vercel · Stripe.
