Privacy Policy

Overview

SubnetPad (https://subnetpad.com) is a free subnet and CIDR calculator. Subnet calculations are performed entirely in your web browser. The IP addresses and CIDR values you enter are not sent to our servers for calculation purposes.

Information we collect

We do not ask you to create an account or submit personal information to use the calculator. We do not intentionally collect the IP addresses or network details you type into the tool.

Like most websites, our hosting provider may automatically record standard server log data (such as your IP address, browser type, referring page, and access time) when you visit the site. We use this information only to operate and secure the service.

Cookies and similar technologies

A cookie is a small text file stored on your device. We may use cookies and similar technologies for the following purposes:

• Essential functionality — for example, remembering your theme preference (light or dark mode).
• Advertising — if we display ads through Google AdSense or another advertising partner, those partners may set cookies to serve and measure ads, limit how often you see an ad, and show ads that may be relevant to you.

Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to users based on their visit to this site and/or other sites on the Internet.

You may opt out of personalized advertising by visiting Google Ads Settings. Alternatively, you can opt out of third-party vendors' use of cookies for personalized advertising by visiting aboutads.info.

For more information about how Google uses data when you use our partners' sites or apps, see How Google uses information from sites or apps that use our services.

Third-party services

We may use third-party services to display advertisements or to help operate the website. These services have their own privacy policies governing how they collect and use data. We do not control third-party data practices.

Children's privacy

SubnetPad is not directed at children under 13, and we do not knowingly collect personal information from children.

Changes to this policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated revision date.
