Does this developer tool upload my input to your servers?

No. These utilities run in your web browser. Your text is processed locally in this tab unless a tool explicitly states otherwise (for example, fetching your public IP uses a minimal server request).

Do I need an account to use this tool?

No account or sign-up is required. Open the tool and use it directly.
