LISTDELTA NOTES

Keep the data path clear.

Local calculation and website hosting are different parts of using the tool.

Pasted lists are processed in this page

This source compares your text locally. It has no upload endpoint, remote calculation API, account, external list fetch, file-picker permission or background comparison service. The calculator does not write your lists to cookies, local storage or session storage. It does not intentionally send the pasted contents to a server.

The optional trim, ASCII-case and NFC operations happen in browser memory. Changing a list replaces the current calculated result. Refreshing or closing the page can discard the text. Browser extensions, device policies and clipboard software are outside the calculator’s control.

Reports and clipboard

Save text and Save CSV generate a local file only when chosen. Copy report asks the browser to write the current report to your clipboard; it does not read clipboard contents. If copying is unavailable, a selectable manual report appears on the page. Reports can contain the entered item text, normalized keys and representative original lines, so handle exported files as you would your source lists.

Hosting and external links

Cloudflare Pages hosts the site. Visiting a page sends ordinary network details to the host, such as the requested URL, IP address, browser information and request time. Hosting or security records are separate from browser-local calculation. See Cloudflare’s privacy policy. Following a guide source link visits another provider under its own policies.

Analytics, advertising and consent

This initial release has no active analytics beacon, advertising script or consent-management loader. Cloudflare Web Analytics automatic injection is not expected for this initial host configuration. Publisher ownership metadata and ads.txt do not themselves load ads. No Google approval, ad serving, audience or earnings claim is made.

If a host setting later enables analytics or the site later enables advertising and consent messages, the privacy page must be updated to match the actual served configuration. Host-injected scripts can differ from the authored source, so later settings need their own verification.

Contact

Email to yardfill.helpful594@aleeas.com goes through an existing shared public forwarding alias and the owner’s email service. Include only a small nonsensitive example needed to reproduce a problem. Do not send passwords, personal datasets, payment details or confidential customer lists. Using the calculator does not send a contact message.
