Calculator inputs
PackFlow is designed so calculator inputs are processed in your browser. Some recent package and shipment values are stored in your browser using local storage so you do not have to re-enter them when moving between calculators.
Accounts and uploads
This version does not require user accounts and does not provide file uploads.
Portfolio Analytics
PackFlow uses the owner’s shared Portfolio Analytics system to understand aggregate page visits and calculator usage. Requests contain the page’s path without query strings or fragments, a fixed event name, and the referring website’s origin when available. Calculator measurements, quantities, calculation results, shipment names, share-link query values, and saved browser data are not intentionally sent to analytics.
The service processes the request IP address and browser user agent to derive salted, site-specific daily visitor estimates and 30-minute session estimates. It stores these hashes with event time, page path, referrer hostname, approximate country, device, browser, and operating-system categories. The analytics client does not set cookies or create visitor identifiers in browser storage. Calculator values saved for convenience remain in local storage on your device.
Share links may contain calculator values. Only share them with people you intend to give those values to.
Advertising
Advertising is currently disabled. No advertising scripts are loaded. If Google AdSense is enabled later, Google and its advertising partners may use advertising cookies and related technologies to deliver and measure ads. Before advertising is enabled, this policy will be updated with the applicable provider details, privacy links, consent choices, and effective date. Visitors in the EEA, UK, and Switzerland will be offered the required choices through Google Privacy & Messaging or another Google-certified consent management platform. No homemade consent banner is used as a substitute for certification.
Local storage
You can clear saved PackFlow values through your browser's site-data controls. Clearing browser storage may remove recent shipment values.
Policy changes
If data practices change, this policy should be updated with the effective date and any additional rights or contact information required by applicable law.
