Frequently asked questions

Does the ROT13 Encoder & Decoder upload my data?

No. The transformation runs locally in your browser. Avoid pasting secrets into any tool you do not control, and clear the fields when using a shared device.

Can I use the result in production?

You can copy or download the result, but review it in the context of your application and run the project-specific tests or validation required by your workflow.
