Privacy Policy
Introduction
Thank you for using this application (hereinafter referred to as "the Service"). We recognize the utmost importance of protecting user privacy and comply with laws concerning personal information protection.
This Privacy Policy describes how user information (input data, etc.) is handled within this Service.
Definition of Personal Information
In this Privacy Policy, personal information refers to information about a living individual that can identify a specific individual by name, date of birth, or other descriptions contained in such information.
Currently, this service does not directly collect personal information such as user's name, email address, address, or phone number, which falls under the above definition, for the purpose of providing the service.
Collection of Personal Information
The Service currently does not offer user registration or login functions, and therefore does not collect personal information such as names or email addresses.
Data entered into the Service, such as "participant names" and "payment details," are treated as data that cannot identify a specific individual on its own. However, if a user enters their real name or similar, it is done so at the user's own responsibility.
Storage of Input Data (Local Storage)
All calculation data entered into this Service is stored exclusively in your browser's local storage function.
- Local storage is a mechanism where data is saved within the user's device (such as a PC or smartphone).
- Saved data is used to restore the state on your next access.
- No input data is sent to external servers.
- It is impossible for any third party, including developers, to access its contents.
Purpose of Use of InputData
Since no personal information is collected, there is no purpose of use.
The data you input will only be used for providing the functions of this Service.
If login features are introduced in the future, the storage location, etc., will be clearly stated after obtaining separate consent.
Provision of Input Data to Third Parties and External Transmission
Except as required by law, input data will not be provided to third parties.
Furthermore, no data will be transmitted externally, including to servers managed by the developer.

About Access Analysis Tools
We may use access analysis tools such as Google Analytics to collect statistical information for site improvement.
The information collected is anonymous and cannot identify individuals.
Please refer to Google's Privacy Policy for details.
Management and Deletion of Input Data
Data stored in local storage can be deleted from your browser's settings.
Note: Data cannot be recovered once deleted. Please keep a separate record if necessary.
