Your answers on this website
Quiz answers stay in memory in your browser tab. They are not submitted to a score database and disappear when you reload or close the page. We do not ask for an account, name or email to play.
Analytics and hosting
This site counts events such as test completion and App Store button clicks using Aptabase, an open-source analytics tool we run on our own server at insights.appxlab.link. Your data is not sent to a third-party analytics company. No cookies are set and no advertising or device identifier is used; a session identifier is held in the page and discarded when you leave. We do not send raw answers, names, challenge codes or full referrer URLs. If your browser sends Do Not Track, nothing is recorded. Hosting providers may process standard request logs including IP addresses; their retention depends on hosting configuration.
Sharing and external links
Sharing sends the puzzle URL to the service you choose. App Store links include a campaign label and, when configured, an Apple provider token. Apple and sharing services apply their own privacy policies.
Inside the mobile app
The app stores results and streaks locally and uses usage analytics and native advertising services. Its current App Store privacy information and in-app privacy settings describe that separate experience. Use More → Delete all my data to erase local app data.
