Privacy Policy
What we do (and don't do) with your data
Our Commitment to Privacy
DutyCalc Online is 100% client-side. All calculations run in your browser. We don't collect, store, or transmit any cargo values, shipping costs, or calculation results to any server. The numbers you enter never leave your device.
Information We Do Not Collect
DutyCalc Online does not collect, store, or process:
- Personal identification information (name, email, address, phone number)
- Cargo values or shipping costs you enter into calculators
- Calculation results or landed cost estimates
- Browser fingerprints, device identifiers, or tracking data
- IP addresses or geolocation data
Newsletter (Optional)
If you choose to subscribe to our Weekly Tariff Briefing, we store only the email address you provide. This data is stored locally in your browser's localStorage — it does not leave your device. No third-party email service processes this data. You can clear it at any time by clearing your browser data.
Cookies & Third-Party Advertising
DutyCalc Online uses Google AdSense to display advertisements. Google and its third-party vendors use cookies to serve ads based on your prior visits to this website and other websites. These cookies allow Google and its partners to show you relevant ads.
- Google's use of advertising cookies enables it and its partners to serve ads based on your visit to DutyCalc Online and/or other sites on the Internet.
- You may opt out of personalized advertising by visiting Google Ads Settings.
- You may also opt out of third-party vendor cookies by visiting NAI Opt-Out or YourAdChoices.
DutyCalc Online itself does not use first-party cookies for tracking, authentication, or functionality. The only cookies set on this domain are those placed by Google AdSense and its advertising partners.
Third-Party Links
Our site links to other tools in our network (FXRate Online, UnitCalc, FreeTool Club). Clicking these links takes you to third-party websites with their own privacy policies. We are not responsible for how those sites collect or handle your data — please review their privacy policies when you visit them.
Children's Privacy
DutyCalc Online is not directed at children under the age of 13, and we do not knowingly collect personal information from children.
Current Advertising Status
As of June 2026, all advertisement placeholders on DutyCalc Online pages are display-only containers. No third-party ad network scripts are loaded, no tracking pixels are fired, and no user data is shared with any advertising intermediary. If and when Google AdSense or another ad network is integrated, this policy will be updated before the first ad impression is served, and the "Cookies & Third-Party Advertising" section above will govern that relationship.
Changes to This Policy
We may update this privacy policy from time to time. Changes will be posted on this page with the last updated date noted below.
