Korean Reps has no accounts. The drill can be used without giving us anything about you.
What the drill records
The drill keeps an anonymous record of each answer and sends them together when you finish a session or leave the page:
- the question (for example, "price:15000") and the mode you were practicing
- whether you were right, and if not, the type of mistake
- how long you took to answer, capped at 2 minutes
- the date, without the time of day
- a random code made fresh each time you open the page, so answers from one visit can be counted together. It is not saved on your device.
- which version of the answer feedback you saw. Each visit randomly gets either the reward effects (lit stations, streak messages, a 10/10 celebration) or plain feedback, so we can see whether the effects help people finish more sessions.
What it never records
No cookies, no device identifiers, no IP address, no browser or device details, no exact time, no country, and no name or email address.
Why
To find the Korean numbers learners miss most, and to improve the questions and explanations. If we share findings, they will be totals only, and only for questions answered at least 30 times.
Turning it off
Switch off "Share anonymous answers to improve this drill" at the bottom of the drill page. Nothing is sent after that. Your choice is kept in your browser's local storage. It is the only thing this site saves on your device.
Deleting your answers
Because the records can't be linked to you, we can't find or delete one person's answers. Switching sharing off stops any new records.
