DENTMAN: Dentist GO! - Privacy Policy

Last updated: 19 October 2026　|　日本語

This app collects no user information. It never connects to the internet. A photo you take with the shutter stays on your own device.

1. Information we collect

• There is no sign-up, no login and no e-mail address to enter.
• There are no fields for a name, date of birth or contact details.
• We do not record usage (no analytics of any kind).
• We show no advertising and pass no data to any advertising network.

2. Camera

The app uses the front camera to detect whether the player's mouth is open.

• Camera images are processed on the device only.
• During normal play the camera image is not shown on screen.
• The image is shown only when the camera button at the bottom right is pressed, so the player can see their own mouth (in a small window, or full screen).
• The image is also shown on the "Detection Test" screen, which clinic staff use to check that the camera is working.
• Only when the shutter button is pressed, that single photo is saved to your device's own photo library. It stays on the device and is never sent anywhere.
• Nothing is recorded or saved on its own.
• We do not store face shape data or facial feature data.
• Images and photos are never sent outside the device (to a server, another app or another machine).

If camera permission is denied or restricted (for example by parental controls), mouth detection cannot work. The app then switches to touch control automatically: the character runs while you hold the screen. Clinic staff can also choose it by hand on the "Detection Test" screen at the bottom right of the title screen.

3. Face data

To detect whether the mouth is open, the app uses the device's face recognition facilities: ARKit face tracking on devices that support it, and the Vision framework's face landmarks on devices that do not. ARKit face tracking is available on devices with a TrueDepth camera and also on devices with an A12 Bionic chip or later.

• What is collected: a single value - the jawOpen blend shape coefficient returned by ARKit - or, on devices that do not support ARKit face tracking, the coordinates of the mouth landmarks returned by Vision. The app does not extract or keep depth maps, face meshes or face images.
• Purpose: solely to determine whether the mouth is open, which is the game's control input. It is never used for identification, authentication, advertising, marketing, profiling or data mining.
• Storage: none. Each frame is converted to a number and discarded immediately. Nothing is written to a file or a database.
• Retention: none. Nothing remains once the app is closed.
• Deletion: there is no retained face data to delete.
• Disclosure and sharing: face data is never disclosed or shared with any third party. The app has no networking capability, so face data cannot leave the device.

A photo saved with the shutter button is an ordinary image and contains no face data (no blend shapes, no landmarks).

4. Network

The app does not connect to the internet. It has no capability to communicate with any external server.

5. Information stored on the device

The only thing the app stores on the device is the settings chosen by the clinic staff: tuning values such as the maximum running speed and the mouth-open threshold, and the display language (Japanese or English). These settings stay on the device, are never transmitted, and are removed when the app is deleted.

Separately, a photo taken with the shutter button is saved to your device's own photo library. It is your photo; we never receive it. You can delete it in the Photos app at any time.

Play results (distance run, time with the mouth open, and so on) are discarded when the app is closed. They are not kept on the device.

6. Children's information

The app is intended for use with children during dental treatment and is distributed in the App Store Kids Category. As stated above, we collect no user information at any age, so no personal information of a child is obtained, stored or transmitted. No third-party analytics or advertising is included. There are no links that leave the app.

7. Disclosure to third parties

Because we collect no information, there is no information to disclose to any third party.

8. Changes to this policy

If this policy changes, the revised text and its date will be published on this page.
