This privacy policy describes what data DimWeightCalc collects and how it's used. Last updated: May 2026.
What we collect directly
The calculator itself runs entirely in your browser. Dimensions, weights, and calculations are not transmitted to any server. We do not store, log, or share your calculation inputs.
We do not require accounts, do not collect email addresses (except when you contact us voluntarily), and do not maintain user profiles.
Google Analytics
We use Google Analytics to understand how visitors use our site in aggregate. Google Analytics collects information such as:
- Pages you visit and time spent on each
- Browser type, operating system, and device category
- Approximate location (country and city, derived from IP address)
- Referring URL (which site sent you to ours)
- Anonymized IP address (IP anonymization is enabled)
Google Analytics uses cookies to track these metrics. You can opt out of Google Analytics tracking by installing the Google Analytics Opt-out Browser Add-on. Google's privacy policy applies to data collected through Analytics: policies.google.com/privacy.
Google AdSense
We display advertisements served by Google AdSense. Google and its third-party vendors use cookies to serve ads based on your prior visits to our website or other websites. Specifically:
- Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to our site 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 some third-party vendors' use of cookies for personalized advertising by visiting aboutads.info
Google AdSense may use the DoubleClick DART cookie to serve ads based on your visit to our site and other sites on the internet. Google's full advertising privacy policy is available at policies.google.com/technologies/ads.
Adsterra
We also display advertisements served by Adsterra, an advertising network. Adsterra and its partners may use cookies, web beacons, and similar technologies to:
- Serve relevant advertisements based on your browsing activity
- Measure ad performance and prevent fraudulent ad clicks
- Build aggregated audience profiles for ad targeting
Adsterra's data practices are described in their privacy policy at adsterra.com/privacy-policy. You can manage your advertising preferences through your browser settings or industry opt-out tools like YourOnlineChoices.com (EU) or NAI Opt-Out (US).
Third-party data sharing
Google AdSense and Adsterra are third-party services. When you visit our site, these services may receive information about your visit including your IP address, browser information, and pages viewed. We do not control what these third parties do with that data beyond what is described in their respective privacy policies.
We do not sell, rent, or transfer your personal information to any other third parties.
Cookies used on this site
This site uses the following categories of cookies:
- Essential cookies: Required for the site to function — such as remembering your selected unit system (metric vs imperial) or shipment type
- Analytics cookies: Set by Google Analytics to measure site usage in aggregate

If you are located in the European Union, you have the right to:
- Access the personal data we hold about you
- Request correction or deletion of your data
- Object to processing of your data
- Lodge a complaint with your local data protection authority
Since we do not directly collect personal data (Google and Adsterra handle the data they collect), most GDPR requests should be directed to those services. For any direct requests, contact us using the link below.
Your rights under CCPA (California residents)
California residents have the right to know what personal information is collected, request deletion, and opt out of the sale of personal information. We do not sell personal information. For specific questions, contact us using the link below.
Children's privacy
This site is not directed to children under 13 (or under 16 in some jurisdictions). We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us so we can remove it.
Affiliate links
Some outbound links on this site may be affiliate links, meaning we may earn a commission if you sign up for a service through our link. This does not affect what we recommend. All such links are clearly marked where applicable.
Changes to this policy
We may update this privacy policy from time to time to reflect changes in our practices or for legal reasons. The "Last updated" date at the top of this page will indicate when the policy was last revised. Continued use of the site after changes constitutes acceptance of the updated policy.
