At Arcoiris Feliz, we take the protection and safe management of the important information entrusted to us by our clients very seriously. Accordingly, we implement the following appropriate and effective security measures:

■ Protection of Email Accounts

All business-related email addresses use secure, paid email services. Two-factor authentication is enabled, and login history is monitored in order to prevent unauthorized access before it occurs.

■ Security Measures for Devices

All devices used for business purposes, such as computers and tablets, are equipped with reliable, paid security software. Continuous malware monitoring and regular system scans are conducted to maintain and enhance safety.

■ Handling of Personal Information

Client communications and personal information are, as a general rule, not stored on external media or transferred to unnecessary cloud services. Instead, they are managed strictly within a controlled local environment.

For payment processing, we use external services such as PayPal, which meet high security standards, to ensure maximum safety.

■ Management of Communication Environment

To eliminate the risks of eavesdropping or interception, we never use public wireless LAN (free Wi-Fi). All business is conducted exclusively through safe and reliable network environments.

■ Access Monitoring and Incident Response

Suspicious login attempts and potential signs of attack are continuously monitored through access log checks. In the unlikely event of an incident, we maintain a system that allows for swift and appropriate response.

We will continue to closely monitor the latest security landscape and strengthen our measures on an ongoing basis, in order to provide an environment where our clients can use our services with the utmost confidence.

(Explanation of Our Policy on the Use of the Gemini App)

(As of April 19, 2025)

At Arcoiris Feliz, all business-related accounts—including Google Workspace—are centrally managed directly by the founder. Account and data management are regarded as matters of the utmost importance and confidentiality.

Currently, the Gemini App (Generative AI) provided by Google is designed to integrate with Google services such as Docs, Gmail, Calendar, and Drive, enabling AI to access and process information based on user inputs.

Given this design, we recognize the need for careful consideration regarding the following points:

■ Concerns Regarding General Use of Gemini

☑ Prompts entered into Gemini may, depending on the user, contain highly confidential information.

☑ Gemini is structured to access data across the entire Google Workspace environment.

☑ There is a nonzero risk that sensitive information—such as communications with clients, personal details, or consultation contents—may inadvertently be transmitted to the AI.

Taking these concerns into account, our site has disabled (deactivated) the use of the Gemini App. We ensure that business-related communications, records, and management information remain secure in an environment not mediated by third-party AI services, with strict administrative controls applied.

■ Key Security Measures

☑ Explicitly disabling AI integration features through Google Workspace administrator privileges.

☑ Centralized account and user management, with strict monitoring and restriction of devices and usage environments.

☑ Regular reviews of external sharing and access control settings to prevent unintentional data leakage.

Moving forward, the adoption of Gemini—or any other AI technology—will be considered only if its specifications and privacy protection policies are sufficiently clarified and it can be determined that the technology fully meets the security requirements of our operations.

We will continue to approach new technologies, including generative AI, with great care—prioritizing not only functionality and convenience but above all the safety and peace of mind of our clients.

We remain committed to maintaining an environment where you can continue to use our services with confidence.
