Privacy Policy

SheetCraft (the "Site") is a pure front-end toolbox. Every Excel / CSV file you process with our tools is parsed and computed entirely inside your own browser via Web Workers. File contents are never uploaded to any server, and the Site cannot access, store or transmit your file data. Once you close or refresh the page, the data is gone from memory.

The Site requires no sign-up and collects no personally identifiable information:

• File data: never collected. All processing is local.
• Interface preferences: theme and certain tool options are stored only in your browser's localStorage and never leave your device.
• Access logs: our hosting provider Vercel keeps standard access logs (IP, browser type, timestamps) for operations and security.

The Site uses no tracking cookies, analytics tools or advertising SDKs. Hosting and content delivery are provided by Vercel Inc., whose own privacy policy governs their data handling.

Because files never leave your device, the architecture eliminates transmission and server-side storage risks by design. Please access the Site via the official domain sheetcraft.top and keep your browser up to date.

Any changes to this policy will be published on this page with an updated date. Continued use of the Site constitutes acceptance of the updated policy.
