Privacy Policy

1. Calculator inputs

Resistance values, color selections, SMD markings, and other calculator inputs are processed in your browser. The calculators do not send these inputs or results to our application server or store them in our database. You can use the calculators without an account.

2. Anonymous feedback

If you submit calculator feedback, we store your message, the name of the corresponding calculator page, submission time, and review status in a private owner dashboard.

The feedback form does not request your name or email address. Please do not include personal, sensitive, confidential, or proprietary information.

Feedback is not a reply channel. If you need a response, use the Contact page.

3. Contact messages

The Contact form stores your reply email address, message, submission time, and status in a separate owner-only inbox. We use this information to respond to and handle your request.

The form does not attach your calculator inputs or results. A hidden spam field and temporary submission limit help reduce automated abuse.

Contact messages are scheduled for deletion 180 days after submission. Expired records are removed during subsequent inbox or submission activity.

4. Hosting and security

OpenAI ChatGPT Sites and supporting Cloudflare infrastructure deliver and protect the website. These providers may process ordinary technical information such as IP addresses, browser details, requested pages, timestamps, and security events according to their own policies.

The site operator uses a sign-in session to access its private administrative dashboard.

5. Google Analytics and cookies

We use Google Analytics to understand page views and site usage. Google may receive page URLs, interactions, timestamps, approximate location, and browser or device information and may use cookies or similar technologies according to its settings and your choices.

We use Analytics reports to improve the site. We do not intentionally send calculator inputs, feedback text, contact messages, or reply email addresses to Google Analytics.

You can learn more about how Google uses information from sites that use its services and can use Google's available privacy and analytics controls.

6. Advertising and Google AdSense

CircuitKitchen uses Google AdSense to display advertising.

Google and its advertising partners may use cookies or similar technologies to serve, measure, and protect ads. Depending on your location, consent choices, and Google settings, ads may be personalized or non-personalized.

Advertising providers may receive information such as page URLs, browser or device information, IP-derived location, ad interactions, and other technical data used to deliver and measure advertising.

We do not intentionally provide calculator inputs, feedback messages, contact messages, or reply email addresses to advertising partners for advertising purposes.

You can review and manage applicable advertising preferences through Google's advertising and privacy controls.

7. Retention and sharing

Contact records are scheduled for deletion after 180 days.

Anonymous feedback may be retained while it is useful for evaluating and improving the calculators and may be deleted by the site operator.

Hosting, analytics, and advertising providers retain information according to their own policies.

We do not sell contact messages or feedback. We share information with service providers only as needed to operate, protect, analyze, and support the site, respond to requests, and meet legal obligations.

8. Your choices and rights

Depending on where you live, you may have rights to request access to, correction of, or deletion of personal information, or to object to certain uses.

Use the Contact page for privacy-related requests.

Because anonymous feedback is not linked to an identity, identifying a particular submission may require its approximate submission time and distinctive wording.

9. Changes

We may revise this policy when the site's features, providers, or practices change. We will update the effective date above and provide additional notice when appropriate.

10. Site operator

CircuitKitchen is operated by TechnologyKitchen.
