To provide the Service, we outsource work to the following external services and have them handle information to the extent necessary. Except as required by law, we do not provide personal data to any other third parties.

The service providers listed above (Cloudflare, Inc., Stripe, Inc., and Google LLC) are U.S. companies, and your information may be processed on servers in the United States and other countries. Information about the personal data protection system of the United States is available on the website of Japan's Personal Information Protection Commission. Each provider takes measures to handle personal data appropriately (such as contractual obligations and security safeguards), which we confirm through our agreements with them.

To understand how the Service is used, we may send information to the following external services (disclosed pursuant to the external transmission rules of Japan's Telecommunications Business Act).

We keep the information we collect only for as long as necessary to achieve the purposes of use, and delete or anonymize it after that period. The specific retention periods are as follows.

• Test answers and results, and email addresses of users who have not purchased: 3 years from your last use
• Account information (for users who have purchased): 3 years from your last use, except that payment and contract records are kept for the period required by law (up to 7 years)
