Privacy and security
- Your input and generated output are processed locally and are not sent to our servers for tool execution.
- Opening a local file uses the browser File API; the file is not uploaded to UtilityKit.
- We may collect anonymous product analytics (for example page views). Tool contents are not included in those events.
- TypeScript Interface Generator runs in your browser; extremely large inputs may be slow or limited by device memory.
- Results depend on your browser’s JavaScript engine and available APIs.
