Privacy Policy

Spreadsheet input

Formula builders use the ranges, cells, criteria, and options typed into the page to generate copyable formulas in the browser. The site does not upload workbook files, does not save spreadsheet inputs, and does not provide an account system.

AI and server processing

The formula builders do not call OpenAI, other AI APIs, or server-side formula generation services. Outputs are assembled from deterministic TypeScript functions and local browser scripts.

Analytics and future ads

The site uses Google Analytics 4 and may also use privacy-conscious analytics such as Cloudflare Web Analytics or behavior analytics such as Microsoft Clarity to understand page views, device types, traffic sources, and usability issues. These analytics are for site-level measurement and are separate from spreadsheet formula inputs.

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. 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.
