Privacy

Hemiscope is a country-geography game with a daily puzzle and an Atlas mode (a 5-round “where in the world” challenge). The short version: we don’t collect personal data, you don’t have an account, and almost everything stays in your browser.

What we store on your device

Hemiscope keeps your in-progress guesses, completed daily-game state, aggregate stats (games played, win streak, guess distribution), your Atlas best-run score, and a flag for whether you’ve seen each tutorial — all in your browser’s localStorage. Nothing in this list ever leaves your device. You can wipe all of it with the “Reset all data” button in the Stats panel, or by clearing site data in your browser.

What we don’t collect

• No name, email, or account information — there is no signup.
• No payment information — the game is free.
• No location, contacts, or device sensors.

Analytics

We use two privacy-focused analytics services to count anonymous, aggregate page visits and measure performance:

• Vercel Web Analytics — cookieless visitor counts. Does not identify individuals or set tracking cookies.
• Vercel Speed Insights — measures page-load and interactivity metrics from real visits. No personal data is collected.
• Google Analytics 4 (when enabled) — aggregate visit counts. May set its own cookies. We do not link visit data to any identity.

If you don’t want any of this, install a tracker blocker or use your browser’s “Do Not Track” setting.

Fonts

Type is rendered using the “Smooch Sans” web font, served from Google’s font hosting. Loading a font from Google’s servers will tell Google your IP address, which is standard for any site using Google Fonts.

Advertising

Hemiscope uses Google AdSense to show ads on the site. Google and its partners may use cookies and identifiers to serve ads based on your prior visits to this site or other sites. You can opt out of personalized advertising by visiting Ads Settings.

Cookies

Hemiscope itself does not set any cookies. Google Analytics, Google AdSense, and Vercel Analytics may set their own cookies (or cookieless identifiers) per their respective privacy practices.

Children

The game is general-audience and does not knowingly collect data from children under 13.
