Information may be processed outside your country
Yakushi Knives operates an international ecommerce store, and its platform and service providers may process or store information in the United States and other countries. Privacy rules and government-access standards may differ from those where you live.

Where law requires a particular transfer mechanism, notice, consent or protective measure, we address that requirement as applicable to the transfer. Customers in Japan should also review our APPI Privacy Notice.
Keeping information only as needed—and protecting it
Retention and safeguards depend on the information, purpose, service involved, risk and applicable legal obligations.
Retention
We retain information for as long as reasonably necessary for the purpose collected, including order fulfillment, support, recordkeeping, fraud prevention, dispute resolution, policy enforcement and legal obligations. Periods vary by category and context.
Security
We use commercially reasonable administrative, technical and organizational measures designed to protect information against unauthorized access, loss, misuse, alteration and disclosure. No transmission, database or security system can be guaranteed completely secure.
The U.S. Federal Trade Commission publishes independent guidance on consumer privacy and data security and protecting personal information.

Subject to applicable law, verification and statutory exceptions, you may be able to request access, correction, deletion or restriction of personal information; object to or opt out of certain processing; withdraw consent; receive portable information; or appeal a decision.
United States
Some state laws provide rights to know, access, correct or delete information and to opt out of certain sales, sharing, targeted advertising or profiling where the law applies.
Canada
Applicable Canadian law may provide rights to understand collection, withdraw consent where permitted, access personal information and request correction.
EEA and United Kingdom
Applicable data-protection law may provide access, correction, erasure, restriction, objection, portability, consent withdrawal and regulator-complaint rights.
Japan
Our APPI Privacy Notice explains eligible disclosure, correction, suspension and related requests where APPI applies.

Use our contact page or email support@yakushiknives.com with “Privacy Request” in the subject line. Identify the request and relevant account or order.
Verify identity and authority
We may request information reasonably necessary to verify identity, locate records and confirm a representative’s authority. This helps prevent unauthorized disclosure or deletion.
We evaluate the request
We assess the request under applicable law. We may ask for clarification or explain when security, another person’s rights, legal privilege, fraud prevention or recordkeeping obligations limit a response.
Receive a response
We respond within the period required by applicable law. If an extension, fee or appeal process is permitted and relevant, we will explain it.
Official rights information is available from the California Attorney General, the Office of the Privacy Commissioner of Canada, and the European Commission.
