Privacy

Last updated 25 October 2026

Lenkub has no accounts, no advertising and no trackers. Almost everything it remembers stays in your own browser. The one thing it ever sends anywhere is a leaderboard entry, and only when you finish a game.

What stays in your browser

None of this leaves your device. We never see it.

  • The name you type before you play.
  • Your best streak in each game, and whether sound is on.

Clearing this site's data in your browser erases all of it.

What is sent to us

Only when you finish a run in a game that has a leaderboard. Nothing is sent while you play.

  • Which game you played and which group of countries you chose.
  • The display name you typed.
  • Your streak, and how long the run took.
  • A random identifier your browser made up the first time you played. It is not derived from your device and is not linked to anything else about you.
  • The time the run was recorded.

The display name is shown publicly on the leaderboard. Choose something you are happy for strangers to see — a first name or a nickname, not a full name.

Cookies

One: the language you picked, so the site opens in it next time. There are no analytics cookies, no advertising cookies, and no third-party scripts of any kind on this site.

Children

Lenkub is made for children and is built so a child can use all of it without handing over anything personal. There is no sign-up, no email address, no age, no location, no contacts and no photos. A parent who wants everything gone can clear this site's data in the browser, and can write to us to have a leaderboard row removed.

Server logs

The site is hosted on Railway. Like any web host, their servers may briefly record request information such as IP addresses for security and reliability. We do not use those records to identify or profile anyone.

Removing something

To have a leaderboard entry taken down, write to us with the name and the game. Everything else is already in your hands: clear the site data and it is gone.

Changes

If any of this changes, the date at the top of this page changes with it.
