This privacy policy explains how Circuit Diagram Maker ("we", "us", "our") collects, uses, and protects information when you use our free, browser-based circuit diagram maker at circuitdiagrammaker.com. We are committed to protecting your privacy and being transparent about our data practices.

2. Information We Collect

Circuit Diagram Maker is designed with privacy-first principles. Here's what we do and don't collect:

• Improve the performance and usability of Circuit Diagram Maker
• Monitor website uptime, error rates, and page load speeds
• Respond to support inquiries submitted through our contact form
• Understand which features of the circuit diagram maker are most used to guide development priorities

4. Cookies & Local Storage

Circuit Diagram Maker uses browser local storage to save your circuit diagrams, component libraries, and editor settings directly on your device. We and our third-party partners also use cookies to ensure core website functionality, analyze web traffic, and deliver personalized and non-personalized advertisements.

You can choose to disable cookies through your individual browser settings. However, disabling cookies may impact certain features and interactive options across the site.

5. Third-Party Services & Advertising

We work with trusted third-party service providers and advertising partners:

• Google Fonts: We load the Inter and JetBrains Mono typefaces from Google's CDN. Google's privacy policy applies to font loading requests.
• Analytics: We use privacy-respecting analytics tools that measure aggregated visitor traffic and comply with GDPR regulations.
• Third-Party Advertising & Google AdSense: We partner with third-party advertising vendors, including Google, to serve advertisements on our site. Third-party vendors, including Google, use cookies (such as the DoubleClick cookie) to serve ads based on your prior visits to this website or other websites across the Internet. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to our site and other sites on the web. You may opt out of personalized advertising by visiting Google Ads Settings (https://www.google.com/settings/ads) or through www.aboutads.info.

We do not sell, rent, or trade your personal information with any third parties for direct marketing purposes.

6. Data Security

Our website is served over HTTPS to ensure encrypted data transmission. Since circuit diagrams are stored locally in your browser, your designs are never exposed to network-level security risks. We follow industry best practices for securing our web infrastructure.
