No Data Collection
SheetToolsHub does not upload or store the spreadsheet content you paste into its tools. Formula building, formula breakdown, comparisons, duplicate analysis, and data cleaning run locally in your web browser.
How It Works
When you use our tools, all processing happens locally in your browser using JavaScript. Your data is never sent to our servers or any third-party services. This means:
- No data is stored on our servers
- No data is shared with third parties
- No cookies track your activity
- No analytics collect your usage data
Browser Storage
SheetToolsHub uses localStorage only to remember your light or dark theme preference. The spreadsheet content entered into tools is not saved to localStorage or sessionStorage. Tool input is cleared when the page is refreshed or closed.
Third-Party Services
We use Google Fonts to load the Inter and JetBrains Mono typefaces. This is the only external service used on our website. No other third-party scripts or services are loaded.
