By using our site or engaging our services, you agree to the practices described below.
1. Introduction
Blue Spark Studio designs and installs off-grid and hybrid power systems for country houses and rural properties across Japan. This policy applies to personal information we collect through our website, during site surveys, and throughout the installation and support relationship with our customers.
2. Information we collect
We collect information you provide directly, such as your name, address, phone number, email address, and details about your property when you request a quote or book a site survey. We also collect information generated during our services, including energy usage estimates, system specifications, and maintenance records.
3. How we collect information
We collect information when you submit a form on our website, correspond with us by phone or email, or when our technicians conduct an on-site survey. Where you consent, we also collect information automatically through cookies and similar technologies, described in more detail in our Cookie Policy.
4. How we use your information
We use the information we collect to prepare quotes and system designs, schedule and perform installations, provide ongoing maintenance and support, process payments, respond to inquiries, and communicate about your project. We may also use aggregated, de-identified data to improve our services and system designs.
5. Legal basis for processing
We process personal information where necessary to perform a contract with you, such as delivering an installation you have requested; where we have a legitimate business interest, such as improving our services; where required by law; or where you have given consent, such as for optional marketing communications.
6. Cookies and tracking technologies
Our website uses cookies to operate core features, remember your preferences, and, with your consent, to analyze site usage and personalize content. You can manage your cookie preferences at any time using the cookie banner on our site or through your browser settings. Full details are available in our Cookie Policy.
7. Sharing and disclosure of information
We do not sell personal information. We may share information with equipment manufacturers to process warranty claims, with subcontracted technicians who assist with installation or maintenance under confidentiality obligations, with payment processors to complete transactions, and with regulators or authorities where required by law.
8. Data retention
We retain personal information for as long as necessary to fulfill the purposes described in this policy, including the duration of any applicable workmanship or equipment warranty, and for a reasonable period afterward to comply with legal, accounting and reporting obligations.
9. Data security
We maintain administrative, technical and physical safeguards designed to protect personal information against unauthorized access, alteration, disclosure or destruction. While we take reasonable steps to protect your information, no method of transmission or storage is completely secure.
10. Your rights
Depending on applicable law, you may have the right to request access to, correction of, or deletion of your personal information, to object to or restrict certain processing, and to withdraw consent where processing is based on consent. To exercise these rights, contact us using the details in Section 15.
11. International data transfers
We primarily store and process information within Japan. If information is transferred to service providers located outside Japan, such as cloud storage or software providers, we take steps to ensure appropriate safeguards are in place consistent with applicable data protection laws.
12. Children's privacy
Our services are intended for adults engaging us for property improvements and are not directed at children. We do not knowingly collect personal information from individuals under the age of 16. If we learn that we have inadvertently collected such information, we will take steps to delete it.
13. Third-party links
Our website may contain links to third-party websites, such as equipment manufacturer sites or financing partners. We are not responsible for the privacy practices of those third parties, and we encourage you to review their privacy policies before providing any personal information.
14. Changes to this policy
We may update this Privacy Policy from time to time to reflect changes in our practices or applicable law. We will post the revised policy on this page with an updated effective date, and material changes will be communicated where appropriate.
