プライバシー ポリシー

1. 概要

SquareYard Calculator ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use our website and calculator tool.

The short version: we collect almost no personal data. Our calculator runs entirely in your browser, and your calculation data never leaves your device.

2. 収集する情報

2.1 計算機データ

All calculations are performed locally in your web browser. We do not collect, store, or transmit any measurement values, dimensions, or calculation results you enter into the calculator.

2.2 お問い合わせフォームデータ

If you use our contact form, we collect the information you voluntarily provide: your name, email address, and message. This data is used solely to respond to your inquiry and is not shared with third parties.

2.3 自動収集データ

Like most websites, our hosting provider may collect basic server logs including:

• IP address (anonymized where possible)
• Browser type and version
• Pages visited and time spent
• Referring website URL
• Date and time of access

This data is used for performance monitoring and security purposes only.

3. Cookie

SquareYard Calculator does not use tracking cookies, advertising cookies, or any third-party analytics cookies. We may use essential session cookies required for basic website functionality.

4. 第三者サービス

We use the following third-party services:

• Google Fonts — to serve web fonts. Google may collect anonymized usage data as described in their プライバシーポリシー.
• Web Hosting Provider — our hosting provider processes server requests. They may collect standard server log data.

5. データセキュリティ

We implement appropriate security measures to protect your personal information. Since our calculator operates entirely client-side, your calculation data is inherently secure — it never leaves your device.

6. 児童のプライバシー

Our Service is not directed to children under 13 years of age. We do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us immediately.
