Privacy Policy — Thatch Blend Zone

Who We Are

Thatch Blend Zone is a water treatment specialist based in Toyohashi-shi, Aichi Prefecture, Japan. We design, supply, install and maintain reverse osmosis systems, home water filters, water softeners and drinking water purifiers for residential customers across Aichi and surrounding prefectures. Our contact details: Toyohashi-shi, Aichi, Japan; telephone +81 532-54-8163. This Privacy Policy explains how we collect, use, store and protect information when you visit our website or contact us about our services.

Information We Collect

We collect information in two main ways: information you provide directly to us, and information collected automatically when you visit our website.

Information You Provide

When you use our contact form to request a consultation, ask about filter installation for your home in the Toyohashi or greater Aichi area, or enquire about maintenance plans for an existing RO system, you may provide us with your name, telephone number, email address, postal address and details of your water treatment requirements. We collect only the information necessary to respond to your enquiry and, if you proceed with a service, to deliver and maintain that service.

Information Collected Automatically

When you visit thatchblendzone.com, our web server and analytics tools automatically collect certain technical information. This includes your approximate geographic location (derived from your IP address), the type of device and browser you are using, the pages you visit and the duration of your visit, and the referring URL — for example, the search engine result page that brought you to our site. This information is used solely to improve our website and understand what content is most useful to our visitors.

Lawful Basis for Processing

We process personal information on the following grounds: (a) your consent, where you have freely given it for a specific purpose such as receiving our newsletter; (b) performance of a contract, where processing is necessary to deliver water filtration installation or servicing you have requested; and (c) legitimate interests, where we have a genuine business need to process data and that need is not overridden by your rights — for example, maintaining service records for equipment we have installed at your property.

How We Use Your Information

We use the information we collect to: respond to enquiries and quotation requests; schedule and conduct installations and service visits; send appointment reminders and follow-up care information related to your water filtration system; fulfil warranty and after-sales obligations; improve our website and service offering; and comply with legal obligations applicable to our business in Japan.

We do not use your personal information for automated decision-making or profiling that produces legal or similarly significant effects on you.

Sharing Your Information

Thatch Blend Zone does not sell, rent or trade your personal information to any third party. We may share information with carefully selected service providers who assist us in operating our business — for example, a scheduling software provider or an email delivery service. Any such provider is bound by contractual obligations to keep your data confidential and use it only for the purposes we specify.

We may disclose information where required to do so by Japanese law, court order or regulatory authority. In any such case, we disclose only the minimum information necessary to satisfy the legal requirement.

Your Rights Under APPI

Japan's Act on the Protection of Personal Information (APPI, 個人情報の保護に関する法律) grants you rights with respect to your personal data held by us. You have the right to request disclosure of the personal information we hold about you; to request correction of any inaccurate or incomplete information; to request deletion of your information where we no longer have a lawful basis to hold it; and to request that we cease using or sharing your information in certain circumstances.

To exercise any of these rights, please contact us by telephone at +81 532-54-8163 or through the contact form on our homepage. We will respond within a reasonable time and in accordance with APPI requirements. We may need to verify your identity before processing your request.

Data Retention

We retain personal information for as long as necessary to fulfil the purpose for which it was collected, or as required by Japanese law. Customer service records — including installation details, filter specifications and maintenance history for your property — are retained for a minimum of five years following the last service date, to support warranty claims and regulatory compliance. Enquiry records from visitors who did not proceed with a service are deleted after 12 months if there has been no further contact.

Data Security

We implement appropriate technical and organisational measures to protect your personal information against unauthorised access, accidental loss, alteration or disclosure. Our website uses HTTPS encryption for data in transit. Access to stored customer records is restricted to authorised members of our team on a need-to-know basis. If we become aware of a security incident that affects your personal information, we will notify you and the relevant Japanese authorities as required by applicable law.

Cookies

Our website uses cookies. For full details of what cookies we use, why we use them, and how to manage your preferences, please refer to our Cookie Policy.

Children's Privacy

Our services are directed at adults making decisions about water treatment systems for their homes. We do not knowingly collect personal information from individuals under the age of 16. If you believe a minor has provided us with personal information, please contact us and we will promptly delete it.

Changes to This Policy

We may update this Privacy Policy when our practices change or when legal requirements in Japan are amended. The updated policy will be published on this page. For material changes, we will make reasonable efforts to notify existing customers directly.
