Privacy

The dimensions are calculated locally.

Skirtmark computes the radii, diagram and area in your browser. This release does not send entered dimensions to a calculation service.

Working state in the page

Calculator input and results are kept in page memory. The code does not save them to cookies, local storage, session storage or a server database. The form is handled locally; its controls do not serialize the dimensions into a page request. The script initializes the example on startup. Your browser may independently restore tabs or form values or keep browsing history, so browser features are separate from the calculator's own state.

Copy and downloaded notes

Copy asks the browser to write the current approximate drafting notes to your system clipboard. Clipboard managers, history features or other software may then retain or access them. If automatic copy is unavailable, a local manual-copy area offers the same current notes. Editing clears the fallback. A clipboard request already sent cannot be recalled, but a late response cannot restore old notes in the page.

Save text and Save JSON create local downloads containing entered dimensions, raw numerical approximations and model limitations. The browser chooses where files are saved and may keep download history or sync them through device backups. The calculator does not upload those files. Review notes before sharing them, especially if the entered values describe a person.

Hosting requests remain separate

The intended host is Cloudflare Pages. Fetching pages or assets makes ordinary hosting requests that may disclose IP address, request time, URL, browser details and referrer to the provider. Provider operational and security logs follow its own policies. Local arithmetic is separate from that connection and does not make a hosting request anonymous.

No active measurement or advertising loader here

This release has no active Cloudflare Web Analytics beacon, ad loader or consent-platform loader. Owner metadata and ads.txt identify the intended publisher but do not themselves load ads or measure entered dimensions. Any later host setup needs matching disclosures and its own verified configuration before activation.

Optional contact

Email sent to yardfill.helpful594@aleeas.com is processed by mail, forwarding and destination providers. The address is an existing verified shared portfolio forwarding alias, not a dedicated new Skirtmark mailbox. Email is outside the local calculator. Do not send passwords, confidential records or personal measurements you do not want to share. See the contact page for useful issue details.
