Privacy Policy
Last updated: 15 October 2026.
This CalcWise privacy policy explains what information CalcWise does and does not collect when you use our free online calculators, and how cookies are used on this site. The short version: our calculators collect nothing, and we are transparent about everything else.
CalcWise Privacy Policy at a Glance
- Calculator inputs: never collected and never sent to our servers — every calculation happens in your browser, on your device.
- Contact form: only the details you choose to provide, used solely to reply to your message.
- Cookies: advertising (Google AdSense) and analytics cookies as described below; you can control or delete them in your browser at any time.
- We do not sell your personal information to anyone.
Information the Calculators Collect: None
Every calculator on CalcWise runs entirely in your own web browser using JavaScript. The numbers, dates, and selections you enter are processed on your device and are never transmitted to our servers, stored in a database, or shared with anyone. When you close or refresh the page, your inputs are gone. This is a deliberate design choice: there is no account system, no saved history, and no tracking of what you calculate.
The Contact Form
If you use our contact form, your name, email address, and message are emailed to the site owner so we can read and reply to your inquiry. Under this CalcWise privacy policy, we use these details only to respond to you. We do not add you to any mailing list, share your details with third parties, or use your message for any other purpose. If you later ask us to delete your message, we will do so.
Advertising Cookies (Google AdSense)
CalcWise is free for everyone because it is supported by advertising, served by Google AdSense. Google and its advertising partners use cookies to serve ads based on your visits to this and other websites. These cookies may collect information such as your browser type, pages visited, and general location (at the country or city level) to show relevant ads and measure their performance. You can opt out of personalized advertising at any time by visiting Google’s Ads Settings.
Analytics Cookies
Where analytics is enabled on this site, it uses cookies to collect anonymous, aggregated information about how visitors use CalcWise — for example, which calculators are most visited and how long people stay on a page. This helps us understand which tools are useful and where to improve. The data is aggregated and does not identify you personally. You can opt out through your browser settings or Google’s analytics opt-out tools.
Other Cookies and Log Data
Like almost every website, the server hosting CalcWise automatically records standard log information — such as IP address, browser type, referring page, and time of visit — for security, troubleshooting, and preventing abuse. We do not attempt to link this technical data to individual identities.
Your Rights Under This CalcWise Privacy Policy
You are in control. You can block or delete cookies through your browser settings (note that some site features, such as saved preferences, may not work without them). If you have sent us a message through the contact form and would like it deleted, just ask and we will remove it promptly. Depending on where you live, you may have additional data-protection rights, such as the right to access or correct personal information we hold about you — contact us and we will respond to reasonable requests.
Children, Changes, and Contact
CalcWise is a general-audience website and is not directed at children under 13; we do not knowingly collect information from children. We may update this CalcWise privacy policy from time to time to reflect changes in our practices or for legal and operational reasons — the “Last updated” date at the top always shows the latest revision, and continued use of the site after changes means you accept the updated policy.
