Privacy Policy
SheetFormulaTools is designed to keep spreadsheet work local to the browser wherever practical.
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 may use privacy-conscious analytics such as Cloudflare Web Analytics or behavior analytics such as Microsoft Clarity to understand page views, device types, and usability issues. Future display ads or sponsorship placements may use standard ad network measurement. These systems are separate from tool input; do not paste private spreadsheet data into any web tool unless you are comfortable with the page context.
