Privacy Policy
This privacy policy describes how 3D Filament Guide (https://3dfilamentguide.com) collects, uses, and protects information about visitors and subscribers. Operated as part of the AI Sec Network. For questions, contact editor@3dfilamentguide.com.
Information we collect
Automatically collected (analytics)
We use privacy-respecting analytics (Plausible) which does not set cookies and does not track individuals across sites. We collect aggregate traffic data: pages viewed, referrer source, browser type, country (not city), and screen size. We do not collect or store IP addresses.
Voluntarily provided (newsletter)
If you subscribe to our newsletter, we collect: email address, the cluster preferences you selected, the source page you signed up from, and the timestamp. This data is stored in our database (Cloudflare D1) and synchronized to our email provider (MailerLite) for delivery.
Voluntarily provided (newsletter via direct embed)
Some sites in our network may embed newsletter signup forms directly. These submit to the same backend as the central subscribe page and are subject to the same data handling.
Cookies
We do not use tracking cookies. We may set a small functional cookie if you opt to dismiss a newsletter banner — this expires after 30 days and contains no identifying information.
How we use information
- To deliver the newsletter you subscribed to
- To improve our content based on aggregate traffic patterns
- To detect and prevent abuse (rate-limiting, spam detection)
- To respond to inquiries you send us
We do not sell, share, or rent your personal data to third parties for marketing purposes. We do not use your data to train AI models. We do not run behavioral advertising.
