Privacy Policy

1. About this policy

Jugemu Tech LLC ("we") operates yadobook (the "Service"), a service that accommodations (each an "Accommodation") use to create and keep their guest registers. This policy describes how guest information is handled in the Service.

The personal information in a guest register is collected and managed by the Accommodation. We store and process it on behalf of the Accommodation.

2. Information we collect

Guests are asked to enter the following information for the guest register:

• Nationality, name, contact details (phone number or email address), age and address
• Arrival date and departure date
• For foreign nationals without an address in Japan: passport number and a photo of the passport
• Depending on the type of accommodation: previous and next destination, or occupation

We also keep the notification email addresses registered by the Accommodation, to let it know about new registrations.

3. Purpose of use

The information is used only to create guest registers as required by Japanese law, such as the Hotel Business Act and the Private Lodging Business Act, and to provide them to the Accommodation. The Accommodation can view and export its guest register through the Service.

We do not use the information for any other purpose, and we do not provide it to third parties except as required by law. The emails notifying the Accommodation of new registrations contain no personal information about guests.

4. Where the information is stored

The information is stored in the Tokyo Region (in Japan) of the Amazon Web Services cloud, which we use.

5. Retention and deletion

Taking into account the retention period required by law (3 years), guest registers and passport photos are deleted automatically 3 years and 1 month after the departure date. The Accommodation may delete them earlier at its own discretion.

Deleted information is also erased from our recovery storage within 7 days, after which it cannot be restored.

6. Security

• All communication is encrypted (TLS), and stored information is encrypted.
• Only the Accommodation's staff who sign in with the Accommodation's password can view the guest register.
• Passport photos are kept in non-public storage, and a short-lived URL is issued each time one is viewed.

7. Cookies

The Service uses cookies only to keep you signed in and to remember your display language. We do not use cookies for analytics or advertising, or any third-party analytics tools.

8. Access logs

To operate the Service, respond to failures and prevent unauthorized access, we record IP addresses, dates and times, the URLs accessed, browser information and similar data. Delivery logs are deleted after 30 days and application logs after 90 days. These logs do not contain the information entered in guest registers.

9. Requests for disclosure, correction or deletion

To request disclosure, correction or deletion of your guest register information, please contact the accommodation where you stayed. We also accept such requests at the contact below and handle them together with the Accommodation.
