2. How We Use Your Information

We use collected information for the following purposes:

• To provide, operate, and maintain the CEMFORGE Service, including generating concrete formulations based on your inputs
• To process subscriptions and payments through our e-commerce platform
• To communicate with you regarding your account, subscription status, or support inquiries
• To send periodic updates via our mailing list (only if you have subscribed; you may unsubscribe at any time)
• To analyze aggregate, de-identified usage patterns to improve service performance and user experience (note: customer formulation inputs are NOT used to train our prediction models — see Section 3)
• To monitor and analyze usage patterns to enhance platform performance and user experience
• To detect, prevent, and address technical issues or security threats
• To comply with legal obligations

3. Machine Learning and Formulation Data

Sunnyday does not use customer mix-design inputs, customer-saved formulations, or customer prediction history to train shared machine-learning models. Customer data is processed to deliver the prediction back to that customer and to maintain account state; it is not added to the training corpus that informs other customers’ predictions.

Our prediction models are trained exclusively on:

• Curated peer-reviewed open-access measured data (publicly cited per the Open-Source Data Citations page).
• Sunnyday in-house laboratory measurements collected on specimens Sunnyday prints and tests directly.

Synthetic or generated mix designs are not permitted in our training data. Every row used in training carries explicit provenance and license metadata.

Additional commitments regarding your data:

• We do not sell individual formulation data to third parties.
• We do not share your specific formulation inputs or results with other users.
• Proprietary formulation data is treated as confidential and is not shared outside of Sunnyday Technologies.

If you have concerns about how your formulation data is used, please contact us at info@sunn3d.com.

4. Third-Party Services

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

• Payment Processing: Subscription payments are processed through WooCommerce and its associated payment gateway. We do not store complete payment card details on our servers. Payment processing is subject to the payment processor’s own privacy policy.
• Website Hosting: Our website is hosted by GoDaddy. Their privacy practices are governed by their own privacy policy.
• Demonstration and Inquiry Hosting: Sunnyday-hosted demonstration content is served via a global content-delivery network. Static demonstration content does not collect personal information. Demonstration, evaluation, and project-report inquiries are handled via email (info@sunn3d.com).
• Analytics: We use cookies for anonymous site analytics as described in Section 1.

We do not sell, rent, or trade your personal information to third parties for their marketing purposes.

5. Data Retention

We retain your personal information for as long as your account is active or as needed to provide the Service. If you cancel your subscription or request account deletion, we will delete or anonymize your personal information within 90 days, except where retention is required by law or for legitimate business purposes (such as resolving disputes or enforcing our agreements).

Aggregated, de-identified data derived from platform usage may be retained indefinitely for research and model improvement purposes.

6. Data Security

We implement reasonable administrative, technical, and physical safeguards to protect your information, including:

• Encrypted data transmission (HTTPS/TLS)
• Hashed password storage
• Access controls limiting employee access to personal data
• Regular security reviews of our infrastructure

No method of electronic storage or transmission is completely secure. While we strive to protect your information, we cannot guarantee absolute security.
