Privacy Policy
Duty collects only what is required to run the calculator and understand aggregate site usage. This page describes what is collected, why, and how to opt out.
What we collect
Aggregate analytics via Google Analytics 4 (GA4): page views, referrer, approximate location at the country level, browser type, and device class. GA4 is configured to anonymize IP addresses.
Server logs at the Cloudflare edge: IP address, request path, response code, and timestamp, retained for at most 30 days for abuse prevention and debugging.
Feedback reports you voluntarily submit through the feedback form (Tally): your answers, optional email address, and optional screenshot. Duty pre-fills only the HTS code, origin, displayed rate, calculation status, data release, locale, feedback source, and a query-free page URL.
Contact details, cargo details, and route information in the freight quote form are collected only when you actively enter and submit them in the external form. Duty auto-prefills only the safe whitelist above (HTS code, origin, displayed rate, calculation status, data release, locale, quote source, and a query-free page URL); GA does not collect form contents.
What we do not collect
We do not collect payment information — Duty is free.
We do not sell, rent, or share your personal data with third parties for marketing.
We do not store the content of your tariff queries on our servers; recent queries live only in your own browser.
Third-party services
Cloudflare (hosting, edge cache, DDoS protection): processes all requests. See Cloudflare Privacy Policy.
Google Analytics (aggregate usage): see Google Privacy Policy. To opt out, install the GA opt-out browser add-on.
Tally (voluntary feedback reports): processes the form answers, optional email, and optional screenshot you choose to submit. Duty does not automatically pass product descriptions, customs values, quantities, account information, or calculator query parameters. See Tally Privacy Policy.
Google Fonts (typography): served from Google CDN. Your browser may share IP and User-Agent with Google when fetching font files.
Your rights
You can request deletion of any data you submitted (for example feedback form contents) at any time by emailing hello@dutylane.com. We will action the request within 14 days.
Recent queries are stored in your browser; clear the site data in your browser settings to remove them.
EU/UK residents: you have the rights granted under the GDPR / UK GDPR including access, rectification, erasure, and data portability. Contact us using the email above to exercise these rights.
