Privacy policy

So, what exactly? ("this site") takes visitors' privacy seriously and follows the applicable laws. Effective September 27, 2026 (revised November 7, 2026). This is a translation of the Korean privacy policy.

1. What we collect

This site has no sign-up or comments, so we do not collect personal data such as names or phone numbers. If you email us, we use your email address and message only to reply, and delete them once that purpose is served.

2. Memory game records

To keep the leaderboard fair, the Memory Palace game issues a random number for each round and stores the start and end time, the number of mistakes and the result on our server.

• A nickname and result appear in the Hall of Fame only if you type a nickname on the result screen and choose to post it.
• We do not store personal data such as IP addresses or email addresses. Rounds without a posted nickname are deleted within two days.
• To remove a posted record, send the nickname and date through the contact page.
• Your best score and last nickname are also kept in this device's browser storage, which you can clear in your browser settings.
