Daniel & Sons Mining Consulting ("we", "us", "our") is committed to protecting your personal information in accordance with the Australian Privacy Act 1988 (Cth) and the Australian Privacy Principles (APPs). This policy explains how we collect, use, store, and disclose your personal information when you use our website and engineering tools.

1. Information We Collect

Account Information

When you create an account, we collect your email address and, if you sign in via Google, your name and profile picture as provided by Google. We store your subscription tier and account preferences.

Calculation Data

If you choose to save calculations, we store the tool inputs and results you provide. Calculation usage (which tools you run and when) is logged for analytics and rate-limiting purposes — input values are not stored in usage logs.

Lead Capture

Certain features (such as the circuit benchmarking tool) require you to provide your email address and consent to this privacy policy before accessing full results. We store your email and the context in which it was provided.

Automatically Collected Information

We use functional cookies for authentication sessions only. We store limited data in your browser's local storage for features like the onboarding wizard and checklist state. We do not use third-party analytics, tracking pixels, or advertising cookies.

2. How We Use Your Information

• To provide and operate our engineering tools and services
• To manage your account and subscription
• To save and retrieve your calculations
• To enforce rate limits and prevent abuse of our platform
• To communicate with you about your account or our services
• To improve our tools and develop new features

3. Third-Party Services

We use the following third-party services that process your data:

• Supabase — Authentication and database hosting (your account data and saved calculations are stored on Supabase's infrastructure)
• Google OAuth — If you choose to sign in with Google, your basic profile information is shared with us by Google
• Stripe — Payment processing for subscriptions (we do not store your credit card details — Stripe handles all payment data directly)
• Replicate — AI image analysis (if you upload images, they are sent to Replicate for processing)

Each of these services has its own privacy policy governing how they handle your data.

4. Data Retention

We retain your account information and saved calculations for as long as your account is active. Usage logs and lead capture data are retained indefinitely for business analytics unless you request deletion. You may request deletion of your account and all associated data at any time by contacting us.

5. Data Security

We implement industry-standard security measures including HTTPS encryption, secure authentication tokens, Content Security Policy headers, and rate limiting. Our calculation models and proprietary data are protected by server-side-only execution — they are never exposed to client browsers.

6. Your Rights

Under the Australian Privacy Principles, you have the right to:

• Access the personal information we hold about you
• Request correction of inaccurate information
• Request deletion of your personal information
• Withdraw consent for marketing communications

To exercise any of these rights, please contact us at the address below.

7. International Users

Our services are hosted and operated from Australia. If you access our services from outside Australia, your information may be transferred to and processed in Australia. By using our services, you consent to this transfer. If you are located in the European Economic Area, you may have additional rights under the General Data Protection Regulation (GDPR).

8. Changes to This Policy

We may update this privacy policy from time to time. We will notify registered users of material changes by email. The "last updated" date at the top of this page indicates when this policy was most recently revised.
