Privacy Policy
Last updated: March 2026
Overview
CalcSystems (calcsystems.com) is a free, static financial calculator website. We do not operate user accounts, require logins, or collect personal information of any kind. Our calculators run entirely in your browser — no data you enter is ever sent to our servers or stored anywhere outside your own device.
Information We Do Not Collect
We do not collect, store, or transmit any of the following:
- Names, email addresses, or any contact information
- Passwords or account credentials
- Financial figures, salary data, or any numbers entered into our calculators
- Payment or banking information
All calculations happen locally in your browser using JavaScript. Nothing you type into a CalcSystems calculator leaves your device.
Cookies & Tracking
CalcSystems itself does not set first-party cookies. However, the third-party services embedded on this site may use cookies or similar tracking technologies:
Google AdSense
We display ads served by Google AdSense. Google uses cookies to serve ads based on your prior visits to this site and other sites on the internet. You can opt out of personalized advertising by visiting Google's Ads Settings.
Google Analytics (if enabled)
We may use Google Analytics 4 to collect anonymized usage data — such as pages visited, time spent on the site, and browser type. This data is aggregated and does not identify you personally. You can opt out by installing the Google Analytics opt-out browser add-on or by adjusting your browser's cookie settings.
Third-Party Services
CalcSystems integrates with the following third-party services, each governed by their own privacy policies:
- Google AdSense — serves display advertisements on this site
- Google Analytics — collects anonymized site usage statistics (if enabled)
For full details on how Google handles data, please review Google's Privacy Policy.
Data Your Browser Stores
Nothing from CalcSystems is stored on our servers. Our calculators run entirely client-side. Some browsers may cache page assets (HTML, JavaScript, CSS) locally to speed up repeat visits — this is standard browser behavior and does not involve any personal data. We do not use localStorage or sessionStorage to retain your calculator inputs between sessions.
Children's Privacy
CalcSystems is not directed at children under the age of 13, and we do not knowingly collect any information from children. If you believe a child has provided personal information through this site, please contact us and we will take appropriate steps to address the situation.
Changes to This Policy
We may update this Privacy Policy from time to time to reflect changes in our practices or for legal and regulatory reasons. When we do, we will revise the "Last updated" date at the top of this page. We encourage you to review this policy periodically. Continued use of CalcSystems after any changes constitutes your acceptance of the updated policy.
