[AI auto-reply in LINE chat]

Enquiries sent in LINE chat, including any images you send, may be answered by an AI auto-reply. This uses the generative AI service of Google LLC (the paid tier of the Gemini API), under contractual terms in which the content sent is not used to train their models. We do not store the text of your enquiry in our database. AI replies are marked as such, and you can switch to a human agent at any time with the button in the chat.

We do not share personal data without your consent except:

(1) with carriers and suppliers, to the extent needed to issue your eSIM;

(2) with our payment provider, to process payment;

(3) where required by law or to protect life, body or property.

Our eSIMs are provided by overseas carriers, so issuing an eSIM involves transferring the information needed for your order to third parties outside Japan.

Principal destinations: the People's Republic of China (including Hong Kong SAR) and the country of the carrier serving your destination.

What is transferred: order number, product code and plan duration.

We do not collect passport details. Where real-name registration is required by law, you register directly with the carrier yourself.

Data protection regimes in those countries differ from Japan's. Under Article 28(2) of the Act, we tell you the destination country, its regime and the measures the recipient takes, and obtain your consent at checkout.

See "Transfers of personal data outside Japan" for details.

We may engage processors as needed (hosting, email and SMS delivery, payment processing).

We require security measures by contract and supervise them appropriately.

We may use Google Analytics and Google Ads tags to understand usage and measure advertising. These use cookies and similar identifiers and do not by themselves identify you.

You can opt out of Google Analytics using Google's browser add-on.

You may disable cookies in your browser, but some features may then stop working.

Order records are kept for the period required by law (generally seven years for accounting records).

We delete personal data without delay once it is no longer needed.

We limit access rights, encrypt communications, keep access logs and take other measures to prevent loss or leakage.

Staff receive training on handling personal data.

[Handling of personal data outside Japan]

We are a corporation headquartered in the United States. Personal data collected by our Japanese office is also handled by our head office in the United States. This is handling by us, within one legal entity — not a transfer to a third party.

The United States has no comprehensive federal data protection law; protection is provided by state laws and sector-specific statutes. There are also regimes permitting government access to information.

Having assessed that external environment, we apply access controls, encryption in transit and access logging.

You or your representative may ask us to notify the purpose of use, or to disclose, correct, add to, delete, suspend the use of, erase, or stop sharing your personal data.

Write to info@esim.co.jp. We may ask for identification.

We do not charge a fee for disclosure requests.

If you are under 18, please use the service with the consent of a parent or guardian.
