5. Access Permissions

6. Use of Location Information

This App may temporarily acquire location information to automatically select currency based on the user's current country information.

• Only "approximate location information (country level)" is acquired, and it does not identify the individual's exact location.
• This location information is not used for purposes other than automatic currency selection and ad delivery, and is not sent or saved outside the App.
• It is acquired only with the user's permission, and use stops immediately if permission is revoked.

7. Ads

This App uses third-party advertising services such as Google AdMob to display banner ads, etc.

• These advertising providers may use Cookies and advertising identifiers to collect information in order to deliver ads based on user interests.

Please refer to the following for Google's privacy policy regarding ads:

9. Privacy Law Compliance for US Users (CCPA/CPRA, etc.)

• This App provides users residing in the US, etc., with the right to opt out of data sharing that may fall under "sale of personal information".
• Users can exercise this right through settings in the app or opt-out links provided by advertising providers.
