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. Analytics events are kept for no longer than 14 months, then deleted automatically. Our analytics server is hosted with OVH in France. 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 MindProof app keeps your results, answers and streaks on your device; there is no account and no sign-up. It counts usage events with the same self-hosted, cookieless Aptabase analytics, on our own server hosted with OVH in France, using a random install ID that is not linked to your identity. These events are kept for no longer than 14 months, then deleted automatically. The app sends no analytics or crash reports to any other company. Its ads come from Google AdMob and are non-personalized: we do not use your activity to target ads, and the app does not ask to track you. Google’s ads SDK still processes a device identifier, your IP address and basic device information to deliver ads, limit how often you see them, prevent fraud and measure ads. In the EU, UK and Switzerland, you are asked for consent before any ad; you can change it at any time in the app’s settings, under “Privacy & ad choices”. To erase local app data, use “Delete all my data” in the app’s settings; it also replaces the install ID with a new one. Full details are in the AppXLab privacy policy at appxlab.io/privacy.html.
