Privacy Policy

Last updated: March 22, 2026

At 3DSearch, we believe in being straightforward about how we handle your data. This policy explains what we collect, why, and what control you have over it.

1. What Data We Collect

We collect only what we need to make the service work well for you:

• Account information: Your email address and display name when you sign up.
• Search queries: The terms you search for on 3DSearch.
• Printer preferences: The printer model and filament type you select when generating AI slicer settings.
• Usage data: Basic analytics like page views, feature usage, and session duration to help us improve the product.
• Device information: Browser type, operating system, and screen size for ensuring compatibility.

2. How We Use Your Data

• Improve search results: We analyze aggregate search patterns to understand what people are looking for and improve result ranking.
• Personalize your experience: Your saved printer and filament preferences let us pre-fill settings so you don't have to reconfigure every time.
• Generate AI settings: Your printer, filament, and selected model URL are sent to our AI provider to generate slicer settings.
• Communicate with you: We may send service-related emails (account verification, important updates). We will never spam you.
• Improve the service: Aggregate, anonymized usage data helps us understand which features are valuable and where to invest effort.

3. Third-Party Services

We use a small number of trusted third-party services to run 3DSearch:

• Supabase — Authentication and database. Your account data and preferences are stored securely in Supabase's infrastructure. Supabase Privacy Policy
• Anthropic (Claude) — AI-powered slicer setting generation. When you request AI settings, we send the model URL, printer, and filament to Anthropic's API. Anthropic Privacy Policy
• Platform APIs — We query Printables, Thingiverse, and Cults3D APIs to fetch search results. Your search query is sent to these platforms. Each platform has its own privacy policy.

We do not sell your data to anyone. We do not share personal data with third parties except as described above to operate the service.

4. Cookies

We use cookies sparingly:

• Essential cookies: Session management and authentication. These are required for the service to work.
• Preference cookies: Remembering your printer and filament selections.

We do not use third-party advertising or tracking cookies.

5. Data Retention

• Account data: Retained as long as your account is active.
• Search queries: Anonymized and aggregated after 90 days. Individual search history is not kept long-term.
• AI settings cache: Cached for up to 7 days to improve response times, then automatically deleted.
• Usage analytics: Retained in aggregate form. Individual session data is deleted after 12 months.

6. Your Rights

You have control over your data:

• Access: You can request a copy of all personal data we hold about you.
• Export: You can export your saved preferences and search history.
• Delete: You can delete your account at any time, which permanently removes all associated personal data from our systems within 30 days.
• Correct: You can update your account information at any time in your settings.
• Opt out: You can opt out of non-essential data collection by contacting us.

To exercise any of these rights, email us at hello@3dsearch.app.

7. Security

We use industry-standard security measures including encrypted connections (HTTPS), secure authentication via Supabase, and environment-variable-based secret management. No system is 100% secure, but we take reasonable steps to protect your data.

8. Changes to This Policy

We may update this privacy policy as the service evolves. We will update the "Last updated" date and, for significant changes, notify you via email if you have an account.
