Privacy, in plain words

Last updated: July 2026

What we store

Game progress (XP, streaks, which capitals you've learned) lives in your browser. If you create an account, a copy is stored on our servers so it follows you across devices.
If you create an account: your chosen username, your email, and a hashed (unreadable) version of your password. Your username and score appear on the public leaderboard.
Anonymous counters: we count things like "how many people played today" — numbers only, not tied to you.
Basic visit analytics (page views, country-level region, device type) via our hosting provider, Vercel — aggregated, no cross-site tracking.
Ad measurement: we use the Meta Pixel to see whether our ads work (page views and anonymous game events like "started a round"). This is standard Meta ad technology and is subject to Meta's privacy policy. No names, emails, or game progress are sent to Meta.

What we don't do

We don't sell or share your data with anyone.
We don't require an account to play — guest play stores nothing on our servers.

Your email

Used only to identify your account and help you recover it. No newsletters, no marketing, unless you explicitly ask for them one day.

Kids

The game is family-friendly by design. Kids can play as guests with zero data collected. Account creation (an email) is intended for a parent or an older player.

There are no ads today. If we ever add them, this page will say so clearly first.
