Privacy Policy

Last updated: 2026-05-03

1. What This Privacy Policy Covers

This Privacy Policy explains how DIY Fume Extractor Specs (the “Site,” operated at solder-smoke-evacuator-build.hub2.day) collects, uses, and protects information when you visit or use the calculator tools on this Site. We are committed to transparency and respecting your privacy.

2. Information You Provide Directly

Calculator Inputs. The fan CFM, filter area, and enclosure dimension calculations run entirely inside your web browser. The numbers and workspace details you type into the tool are not sent to our servers. They remain on your device and are cleared when you close or reload the page unless your browser temporarily stores them for form autofill.

Contact Email. If you choose to email us at [email protected], we receive your email address and any information you include in your message. We use this only to respond to your inquiry and do not add you to marketing lists.

3. Information Collected Automatically

Server Logs. Like most websites, our hosting infrastructure automatically records standard technical details when you access the Site. This may include your IP address, browser type, operating system, referring URL, pages visited, and date/time stamps. These logs are used solely for security monitoring, troubleshooting, and aggregated traffic analysis. They are retained for a limited period and are not combined with other data to identify individuals.

Cookies and Local Storage. This Site itself does not set first-party cookies or use browser local storage for tracking. However, third-party services described below may place cookies on your device.

4. Advertising and Third-Party Services

Google AdSense. We use Google AdSense to display advertisements. Google and its partners use cookies and similar technologies to serve ads based on your prior visits to this Site and other websites. These cookies allow Google to show interest-based ads.

  • Google may use advertising cookies to collect information about your browsing activity for ad personalization and measurement.
  • You can review and control the information Google uses for advertising at Google Ad Settings.
  • For more details on how Google handles data, see Google’s Privacy Policy at https://policies.google.com/privacy.

Third-Party Links. Our Site may contain links to external websites, tools, or resources. We are not responsible for the privacy practices or content of those third-party sites. We encourage you to review their privacy policies.

5. GDPR, EEA, and UK Privacy Rights

If you are located in the European Economic Area (EEA) or the United Kingdom, you have certain rights under the General Data Protection Regulation (GDPR) and UK GDPR. For the limited personal data we may process (such as server log IP addresses or contact emails), these rights may include:

  • Access: Request a copy of your personal data.
  • Rectification: Ask us to correct inaccurate data.
  • Erasure: Request deletion of your data under certain conditions.
  • Restriction: Ask us to limit processing in specific circumstances.
  • Objection: Object to processing based on legitimate interests.

We rely on legitimate interests for essential server-log processing (security and operations) and on consent for personalized advertising where required. You can manage or withdraw consent for personalized ads at any time through the consent management platform presented on your first visit or by adjusting your browser settings to block third-party cookies.

6. CCPA / CPRA Privacy Rights (California and Similar U.S. States)

If you are a resident of California or another U.S. state with comprehensive privacy laws, you may have rights including:

  • Right to Know: Request details about the categories and specific pieces of personal information we collect, use, and disclose.
  • Right to Delete: Request deletion of personal information we have collected from you.
  • Right to Opt-Out of Sale/Sharing: Google AdSense may use data for interest-based advertising, which could be considered a “sale” or “sharing” under certain state laws. You can opt out of personalized advertising by visiting Google Ad Settings or by enabling Global Privacy Control (GPC) signals in your browser.

We do not knowingly sell personal information for monetary consideration. To exercise your rights, contact us at [email protected]. We will verify your request and respond within the time required by law.

7. Children’s Privacy

This Site is intended for a general audience of electronics hobbyists and makers. We do not knowingly collect personal information from children under 16. If you believe a child has provided us with personal data, please contact us so we can delete it.

8. Data Security and Retention

We implement reasonable technical and organizational measures to protect the information we process. Server logs are retained only as long as necessary for security and operational purposes. Contact emails are retained for the duration of the correspondence and a reasonable period thereafter for record-keeping.

9. International Data Transfers

Our hosting infrastructure may be located in various countries. When you access the Site from outside those countries, your information may be transferred to, stored, and processed in a jurisdiction that may not provide equivalent data protection laws. We take steps to ensure appropriate safeguards apply where required by law.

10. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. The “Last updated” date at the top will reflect the most recent changes. Continued use of the Site after changes constitutes acceptance of the revised policy.
