About the Handling of Information on This Website

This page describes the handling of personal information on the AIRDO website. Please see AIRDO's Privacy Policy for more information about the handling of various types of personal information by AIRDO.

1. Introduction

AIRDO has established the following terms related to the handling of information on this website (hereinafter, "this website") on the basis of AIRDO's Privacy Policy, and AIRDO is committed to operating and managing this website in a way that allows customers to use it with peace of mind.
Your use of this website indicates that you fully understand and agree to the following terms.

Scope of Applicability

These terms apply to the customer's use of this website (the airdo.jp domain name) and not to websites operated by other companies. This website provides links to other websites in order to provide useful information and services to customers. Our Privacy Policy does not apply to linked website. We recommend that you review the privacy-related statements of each individual website that you visit.


Security technology for protecting personal information
When receiving personal information from customers, AIRDO ensures security by encrypting personal information through SSL (secure sockets layer) encryption technology or an equivalent security technology in order to prevent unauthorized access by third parties during transmission.
Furthermore, AIRDO strives to ensure the safety of customers' personal information by installing firewalls, implementing measures to prevent computer viruses, and taking other reasonable security measures in order to prevent leaks, misappropriation, and falsification of personal information due to unauthorized access by third parties.

Note:Regarding our SSL (secure sockets layer) setup
  • SSL involves the electronic exchange of security-related data (digital authentication and digital signatures) between AIRDO and customers prior to the transmission of personal information by the customer, so that data is transmitted only after mutual authentication has taken place. When this takes place, exchanges between AIRDO and customers are altered by random numbers to prevent erroneous transmission to any third party that would impersonate the customer and attempt to steal data.

Furthermore, information transmitted via SSL is encrypted using a combination of two different encryption methods: public key encryption (RSA) and symmetric key encryption (secret keys). An electronic "key" is required to decode this information. Even if the information is intercepted by a third party, it is impossible for them to decrypt the encrypted information without the correct key. The number of keys is finite, but it takes an impractically long time to try all keys in order to figure out the correct one even if the work is done electronically by computer. Therefore, it is extremely difficult for a third party to decrypt the information.
