Privacy and cookies

Last updated 15 October 2026

PortBill is a wharfrent billing calculator. It is run by samiulAsumel and is for information and estimation only. This notice lists what the site stores. It describes how the software works; it is not legal advice.

Cookies

PortBill sets no cookies of its own. It uses your browser's local storage (described below) instead.

Stored in your browser

Saved bills, drafts and the bill-number counter, so your work survives a reload.
Rate settings, rotation registry copy, table and sidebar preferences.
A random device identifier used for anonymous usage counting (see below).
A short-lived sign-in lock counter and, for signed-in users, a per-user stash of General Cargo bills.

You can remove all of this by clearing the site's data in your browser settings.

Sent to the PortBill server

Saved bills. Bills you save are copied to the PortBill server, which keeps them in the owner's GitHub storage. A bill can contain the fields you typed, such as the bill-of-lading number, the C&F agent name and the bill-of-entry details. Do not enter anything you do not want stored.
Anonymous usage counts. Once per browser session the page sends the random device identifier and the day. No name, no IP address and no personal data are added to this count.
Sign-in accounts (General Cargo users). The administrator creates these accounts. The server holds the username, a salted password hash, the company name and the contact number given for the account, the access period, and a log of sign-ins and account changes with the IP address. Passwords are never stored in readable form.

Third-party analytics

The site uses Cloudflare Web Analytics, a cookieless, privacy-focused page-view counter, and is hosted on Cloudflare. See Cloudflare's own privacy policy for how it handles request data.
