Tool input

Formula builders and calculators use values typed into the page to produce results in the browser. Developer tools transform pasted text locally. The bead-pattern maker processes selected images in browser memory and does not upload them. The public site does not provide an account system.

AI and server processing

The formula builders do not call OpenAI, other AI services, or server-side formula generation services. Outputs are assembled from built-in spreadsheet rules and browser scripts.

Analytics and future ads

Analytics and advertising scripts are disabled in the default build. If site-level analytics are enabled later, they may measure page views, device types, traffic sources, and tool actions, but they must remain separate from values entered into tools.

The site does not send typed formula ranges, criteria, pasted CSV text, or spreadsheet file contents as custom analytics events. It may track site-level actions such as tool use, copied results, template downloads, outbound link clicks, PDF downloads, and optional email form submissions. Future display ads or sponsorship placements may use standard ad network measurement only after the applicable consent controls are enabled. Do not paste private spreadsheet data into any web tool unless you are comfortable with the page context.

If an email capture form is shown, it sends the submitted address only through the configured form action or mail client. The static site itself does not create an account, database, or local email list.
