Privacy Policy

Effective date: 2026-09-27

This policy explains what information CircuitNote ("the site") handles and how.

1. Information we collect

The site has no accounts and does not directly collect information that identifies you, such as your name or contact details. Values you enter into the calculators are processed only in your browser and are never sent to or stored on a server.

2. Cookies and advertising

To cover running costs, the site may show third-party ads such as Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this site or other websites.

• Google's use of advertising cookies lets it and its partners serve ads based on your visits. See how Google uses cookies in advertising.
• You can opt out of personalized advertising in Google Ads Settings.
• You can also block cookies in your browser settings. The calculators keep working if you do.

3. Server logs

The hosting provider may automatically record access logs, such as IP address, browser type and time of visit, for security and reliability. The site owner does not use these logs to identify individuals.

4. Visit statistics

To improve the site, we look at aggregate statistics such as page views, referrers, countries and device types through Cloudflare Web Analytics. It does not use cookies and does not track or identify individual visitors.
