Privacy Policy

1. Information We Collect

At xsheetkit, we respect your privacy. Because processing is handled completely locally on your client machine:

• We do not collect personal info or request user accounts.

• We do not upload or store the content of your Excel, CSV, or JSON spreadsheets.

• We only monitor anonymous performance metrics (total computation time) to optimize the engine.

2. Secure Resource Loading

We use background processing in your browser to handle calculations without freezing your user interface.

We dynamically load secure resources and libraries from verified public distribution networks. This process consists solely of downloading static scripts required for in-browser computation and never transmits any spreadsheet content to external servers.

3. Local Settings (Cookies & LocalStorage)

We may store user preferences (like your preferred language) in your browser’s LocalStorage to personalize your experience on return visits.
