Privacy Policy

Short version: Cal44 runs entirely in your browser. We do not transmit, store or sell your calculation inputs. We have no user accounts. This page explains the details.

Last updated: 2026-05-24

1. What Cal44 is

Cal44 (cal-44.com) is a static, client-side web application providing 31 calculator tools. The application is delivered as HTML, CSS and JavaScript from a static host (Cloudflare Pages).

2. Information we do not collect

• We do not collect, transmit or store your calculator inputs (principal, rate, weight, dates, etc.).
• We do not require any signup, account creation or login.
• We do not sell, rent or share any user data with third parties.

3. Information your browser stores locally

To remember your preferences (default currency, unit system) across visits, Cal44 may use your browser's local storage (localStorage). This data never leaves your device. You can clear it at any time from your browser's site-data settings.

4. Hosting provider logs

Our host (Cloudflare Pages) processes standard server logs that include IP addresses, request URLs and timestamps for security, abuse prevention and capacity planning. These logs are subject to Cloudflare's privacy policy. Cal44 does not access individual user records in these logs.

5. Cookies and analytics

Cal44's static site does not set tracking cookies. We do not run third-party analytics (Google Analytics, etc.) on calculator pages at this time. If we add anonymised, privacy-friendly analytics in the future, this section will be updated and we will not start tracking retroactively.

6. Advertisements

Cal44 may display banner advertisements served by a third-party ad network (e.g. Monetag) on certain pages. Ad networks may use their own cookies and tracking technologies subject to their own privacy policies. We do not pass any calculator input data to ad networks.

7. Children

Cal44 is suitable for general audiences. We do not knowingly collect any data from anyone, including children under 13 / 16 (jurisdiction-dependent).

8. Your rights

Because Cal44 does not collect personal data, most data-rights requests (access, deletion, portability) resolve trivially: there is nothing to access, delete or port. For any concerns, contact hello@44systemstech.com.

9. Changes to this policy

If material changes are made to this policy, the "Last updated" date will change and a summary will appear at the top of this page for a reasonable period.
