Korean Cards is run by Alok Studio (알록스튜디오), a business registered in the Republic of Korea (registration number 222-30-01872). You can reach us at [email protected].
There is no account, no advertising, and no tracking or analytics script on this site.
Your learning progress is kept in your own browser, not on our server.
We store your progress, score, collected cards, daily count, guest id and preferences in your browser’s local storage, and your chosen language in a cookie.
This data never leaves your device unless you send it to us yourself. We cannot read it.
Clearing your browser data deletes it permanently. We cannot restore it, because we never had a copy.
Like any website, our server and its security layer record ordinary request logs: IP address, browser and operating system string, the page requested, and the time.
We use these only to keep the service running and to spot abuse, and we do not use them to build a profile of you.
Cloudflare — domain, network and protection. Your request passes through their network before it reaches our server.
Google Fonts — the typefaces are fetched from Google’s servers, so your IP address is visible to Google when a page loads.
Our own rented server, which runs the site and its database.
We do not ask for an email address, a name, or any social login, and we do not take payments.
When sign-in or payment is added, this page is updated before the feature goes live, and the update will say exactly what is collected.
This service is not directed to children under 13 (under 16 in the European Economic Area), and we do not knowingly collect their data.
You may ask us what we hold about you, and ask us to delete it. Write to us at the address below.
In practice we hold almost nothing that identifies you: your progress is on your device, and you can erase it yourself at any time by clearing your browser data or using “Start over” in Settings.
If this policy changes, the new version appears here with a new date. Meaningful changes will also be announced inside the app.
