Privacy Policy
Last updated: May 2025
This privacy policy describes how kalq.net collects and uses information when you visit this site. The short version: the tools themselves collect nothing. The site uses standard analytics to understand traffic patterns. Ads may be served by Google.
The calculators and tools
Every calculator and converter on this site runs entirely in your browser using JavaScript. No numbers, inputs, or results are transmitted to any server. When you calculate a mortgage payment or enter personal health data, that information never leaves your device. I do not receive it, store it, or have access to it.
Analytics
This site may use Google Analytics to collect anonymized information about site usage, including pages visited, time on site, general geographic region, browser type, and referring site. This data helps me understand which tools are most useful and how people find the site. It does not include personally identifiable information.
Google Analytics uses cookies to track sessions. You can opt out of Google Analytics tracking using the Google Analytics opt-out browser add-on.
Advertising
This site may display advertisements served by Google AdSense. Google uses cookies to serve ads based on a user's prior visits to this website and other sites. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to this site and other sites on the Internet.
You may opt out of personalized advertising by visiting Google Ads Settings. You can also opt out of a third-party vendor's use of cookies for personalized advertising by visiting aboutads.info.
Cookies
This site uses a small number of cookies:
- Favorites storage: If you star a tool as a favorite, that preference is saved in your browser's localStorage. This data stays on your device and is never transmitted anywhere.
- Analytics cookies: Set by Google Analytics if analytics are enabled. These are used to distinguish users and sessions for traffic analysis.
- Advertising cookies: Set by Google AdSense if ads are displayed. These may be used to serve personalized advertisements.
Third-party services
This site loads fonts from Google Fonts and may load JavaScript libraries from CDN providers. These requests may allow third parties to see that you visited this site. Their privacy practices are governed by their own policies.
Children's privacy
This site is not directed at children under 13 and does not knowingly collect information from children. If you believe a child has provided personal information through this site, contact me at cholmx@gmail.com and I will remove it.
Changes to this policy
If this privacy policy changes materially, I will update the date at the top of this page. Continued use of the site after any changes constitutes acceptance of the updated policy.
