Privacy
Hemiscope is a set of six daily puzzle games — Hemiscope, Vault, Timeline, Pinpoint, Top 10 and Atlas — playable free at hemiscope.com and in the Hemiscope iOS app. The short version: there is no account, we don’t collect personal data, and your progress stays on your device.
The website and the app differ in one way that matters, so they’re described separately below: the website carries ads and analytics; the app carries neither.
The iOS app
The app collects nothing. There is no analytics SDK, no advertising, no tracking, and no third-party code that reports on you.
Your in-progress games, completed daily results, stats and streaks, and your “don’t show this again” preferences are stored on your device using the system’s own app storage. None of it is uploaded, and it is deleted with the app.
The app makes network requests for exactly two things, both of them images: country flags from flagcdn.com, and the Top 10 photographs from upload.wikimedia.org. These carry no identifier and no information about you or your game. As with loading any image on the internet, those servers see the request and your IP address.
The app ships a privacy manifest declaring no tracking and no collected data. Tapping a link to hemiscope.com — for photo credits, for example — opens your browser, at which point the website terms below apply.
The website
What we store on your device
The site keeps your in-progress guesses, completed daily-game state, aggregate stats (games played, win streak, guess and score distributions), and a flag for whether you’ve turned off each game’s intro — all in your browser’s localStorage. Nothing in this list ever leaves your device. You can wipe it with the “Reset all data” button in the Stats panel, or by clearing site data in your browser.
Analytics
- Vercel Web Analytics — cookieless visitor counts. Does not identify individuals or set tracking cookies.
- Vercel Speed Insights — page-load and interactivity metrics from real visits. No personal data is collected.
- Google Analytics 4 — aggregate visit counts. May set its own cookies. We do not link visit data to any identity.
Advertising
The website uses Google AdSense. Google and its partners may use cookies and identifiers to serve ads based on your prior visits to this site or others. You can opt out of personalised advertising at Google Ads Settings. We also run a Google Ads conversion tag to measure whether our own advertising works.
If you’d rather have none of this, install a tracker blocker — or play in the iOS app, which has no ads and no analytics at all.
Cookies
Hemiscope itself sets no cookies. Google Analytics, Google AdSense and Vercel Analytics may set their own cookies (or cookieless identifiers) under their own privacy practices.
Fonts
Type is set in Smooch Sans, Space Grotesk, Figtree and IBM Plex Mono. These are Google Fonts, but they are downloaded at build time and served from hemiscope.com — your browser makes no request to Google to load them.
What we never collect, anywhere
- No name, email, or account information — there is no signup.
- No payment information — every game is free.
- No location, contacts, photos, or device sensors.
Children
Hemiscope is a general-audience game and does not knowingly collect data from children under 13.
Changes to this policy
We’ll update this page if our practices change. Adding an analytics SDK to the app, for instance, would mean rewriting the app section above — and until that happens, what it says is exactly true.
