KatakataLab is a personal web-tool project created and maintained by Katakata in Japan. The English section provides focused browser utilities and explanatory material for international visitors.
Tool pages describe their intended workflow, limitations, and data handling. Dates indicate the latest editorial review, not a promise that every third-party platform remains unchanged. Corrections can be sent through the contact page.
New English pages are currently served without display advertising while usefulness is evaluated. Normal analytics may process page-view and device information. Tool-specific input handling is described on each page. The authoritative site privacy policy and terms are currently published in Japanese.
