Privacy

Last updated: July 2026.

The short version

You can play everything on this site without an account and without giving us anything. Your game progress — streaks, passport stamps, quiz results — lives in your own browser (localStorage), not on our servers.

What we store, and when

• Game scores. After you finish a daily round, an anonymous result (day number, guess count, an optional callsign you chose, and a random identifier your browser generates) is sent to our database to power the worldwide stats and crew rooms. It contains no name, no email, no location.
• Email address. Only if you ask for the sample chapter, updates, or unlimited game play. We store it in our own database, use it to send your sign-in link and occasional offers from Charlie Center, and nothing else. Unsubscribe works with one click, and we never sell or share the list.
• Corporate inquiries. What you type in the inquiry form is stored so we can reply, and emailed to Issam. Nothing else is done with it.

Analytics

We use Google Analytics 4 and Cloudflare Web Analytics to understand which pages are read and whether clicks reach the book's Amazon page. These tools use cookies or aggregate measurements; we see statistics, not identities.

Third parties

• Hosting and analytics: Cloudflare and Google Analytics.
• The Amazon links on this site lead to Amazon's own store, under Amazon's terms.
• Game photos load from Wikimedia Commons servers.

Your choices

Clear your browser storage and every trace of your play history is gone. Email issam@charlie.center to have your subscription or inquiry data deleted — we do it, no questions.
