Privacy policy

Last updated November 11, 2026.

Guessamillion is a free daily guessing game. This page explains what we collect and why.

What we store

• Your display name, which appears publicly on the Rich List.
• Your sign-in details, if you create an account: your email address and a salted, one-way hash of your password (we never store the password itself). If you sign in with Google, we receive your Google account ID, email address and first name from Google, and nothing else.
• A random account key, saved in your browser's local storage so you stay signed in on that device.
• Your game record: guesses, bets, net worth, streak and days played.
• A one-way hash of your IP address, used only to limit how many accounts can be created from one network per day. We do not store your IP address itself.

Your email is never shown to other players. We don't ask for your phone number or payment details, and we don't sell your data.

Advertising

We may show ads from third-party vendors, including Google. These vendors use cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visits to this and other sites. You can opt out of personalized advertising in Google Ads Settings, or opt out of some third-party vendors' cookies at aboutads.info.

Hosting

The game runs on Cloudflare, which processes requests to deliver the site and protect it from abuse.
