Navier Stokes Explained: Privacy Policy
Navier Stokes Explained is an educational fluid simulation for iPhone published by King of the Hour. This policy covers the app only. The website kingofthehour.com has its own privacy policy.
What the app itself collects
Nothing. The app has no accounts, no sign-in and no analytics of its own, and it does not send your activity to us. Your settings and lesson progress are stored on your device and are removed when you delete the app. All lessons and experiments work offline.
Motion sensors
If you turn on Tilt, the app reads your phone's motion sensors so that gravity in the tank follows your phone. That data is used on your device, only while Tilt is on, and is never stored or transmitted.
Advertising
The app is free and shows ads on its menu and reference screens through Google AdMob. Lessons and the simulation itself do not show ads. To deliver and measure ads, and to prevent fraud, Google may collect and process:
- your device's advertising identifier and other device identifiers;
- your IP address, which can indicate your general location;
- information about the ads you see and how you interact with them and with the app;
- diagnostic information such as crash logs and performance data.
This information goes to Google, not to us, and Google handles it under its own policies. See how Google uses information from apps that use its services and the Google Privacy Policy. Ads are requested with a general-audience content rating.
Your choices
- Where the law requires it, the app asks for your consent before requesting ads. You can change that choice at any time in the app under Controls › Quality & model › Privacy choices, where that option is shown.
- The app asks for your permission before your activity is tracked across other companies' apps and websites. You can decline, and you can change your answer later in iOS Settings › Privacy & Security › Tracking. Declining does not limit any feature of the app.
- You can reset or limit your advertising identifier and personalized ads in iOS Settings.
Children
The app is intended for a general audience and is not directed to children under 13. We do not knowingly collect personal information from children.
Changes to this policy
If this policy changes, the new version will be posted on this page with a new effective date.
