• In-app settings: ISO settings, exposure modes, metering modes, calibration values, and various display settings are saved on the device.
• Shooting assistance information: Camera body name, lens information, film name, shooting records, and reference information for saved images are saved on the device.

2. Purpose of Information Use

• To measure subject brightness and display approximate exposure values and shooting conditions.

3. Handling of Camera Information

This application uses the camera to provide the exposure measurement function. Camera footage is primarily processed within the device and used for exposure calculation and preview display. The operator of this application does not collect camera footage itself, unless the user voluntarily uses the login function.

4. Handling of Photo Library

This application adds and saves shooting record images, etc., to the device's photo library only when the user performs a save operation. This application's primary purpose is not to read existing photos from the photo library.

5. Shopify Login and External Service Integration

This application includes Shopify login as an optional feature. If the user uses this feature, it may communicate with Shopify and backend services for authentication assistance to process authentication. In this case, this application will use the name, email address, customer ID, customer account URL, etc., acquired as a result of authentication, for display within this application and for account linking.

Shopify login is an optional feature; the main functions of the light meter can be used without logging in.

6. On-Device Storage

This application saves setting values, calibration values, presets, shooting records, and some login status information on the user's device. These are used to improve the convenience and continuous use of this application.

7. Provision to Third Parties

This application does not provide users' personal information to third parties, except where required by law. However, if the user voluntarily uses the Shopify login function, necessary information will be sent and received between Shopify and authentication assistance services for authentication and customer information acquisition.

8. Analytics, Advertising, and Tracking

This application does not perform tracking for advertising purposes. As of the establishment date of this privacy policy, behavioral tracking using advertising identifiers is not conducted.

9. Information Management and Deletion

• Settings and shooting records stored on the device may be deleted by user operation, logout, or app uninstallation.
• Information retained through Shopify login may be deleted from within this application upon logout.
• Images saved to the photo library can be deleted by the user themselves through the device's photo app or similar.

10. Use by Minors

This application does not specifically restrict use by minors, but please use it with parental consent if necessary.
