Privacy Policy
We respect your privacy and keep data collection to a minimum.
Information we collect directly
This sales page does not ask you to create an account or submit personal information. We do not run a contact form or newsletter sign-up on this page. If you email us, we receive whatever information you include in your message and use it only to respond to you.
Purchases
All purchases are processed by Gumroad, a third-party platform. When you buy, your payment and contact details are handled by Gumroad under its own privacy policy and terms — we never see or store your full payment information. Please review Gumroad's policies for details on how it handles your data.
Cookies, local storage & third-party services
To make the site work, your browser may store small amounts of data locally (for example, to remember a promotional timer). The site also loads fonts from Google Fonts and is hosted on Vercel; these providers may automatically receive technical data such as your IP address and browser type as part of delivering the page.
We use privacy-focused analytics to understand how visitors use the site so we can improve it: Cloudflare Web Analytics, which is cookie-free and does not track you across other sites, and Microsoft Clarity, which uses cookies and may capture anonymized interactions such as mouse movement, clicks, and scrolling (with sensitive input automatically masked) to produce aggregate heatmaps and session insights. These tools help us see which parts of the page are useful and where visitors get stuck. You can clear cookies and local storage in your browser at any time.
Children
This site and product are intended for adults and are not directed to children.
Your choices
You can clear cookies and local storage in your browser at any time, and you can contact us at the email above with any privacy question or request regarding information you have shared with us.
Terms of Use
Educational purpose
The Washitsu guide and all content on this site are provided for general educational and informational purposes only. They reflect traditional household practices and personal experience. They are not professional pest-control, medical, veterinary, or legal advice. No outcome is promised or guaranteed; homes, climates, and infestations differ, and results will vary.
Use at your own risk
By using any method described in the guide, you accept full responsibility for the results. "Natural" does not always mean "harmless" — some materials require care. Always read and follow product labels, ventilate enclosed spaces, keep all preparations out of reach of children and pets, and consult a licensed professional for serious infestations (such as termites, bed bugs, large rodent problems, or stinging-insect nests). To the fullest extent permitted by law, the publisher is not liable for any injury, illness, property damage, or loss arising from the use or misuse of the information provided.
Intellectual property
The guide, bonuses, text, and images are protected by copyright. They are licensed for the personal use of the purchaser and may not be reproduced, shared publicly, or resold without written permission.
Sales and delivery
Products are sold and delivered as digital downloads through Gumroad. Your purchase is also subject to Gumroad's terms of service.
Refund Policy
Your purchase is covered by a 14-day money-back guarantee. If within 14 days of purchase you feel the guide hasn't helped you keep your home cleaner, calmer, and more pest-free, email support@thehiroshitanaka.com with your order details and we'll issue a full refund — no hard feelings. Refunds are processed through Gumroad back to your original payment method.
