Text you enter in the tools
The generator, signature maker, practice sheets, and tracing tools process your input in this browser. They do not upload your text for conversion or create a public gallery. The tracing canvas is held only in the open page.
My Words and preferences
My Words uses localStorage under the key wordbook. The selected font, output settings, and an explicitly chosen language may also be stored on this device. These entries are shared by the Japanese and English tools on the same website. They are not synchronized to an account. Removing site data in your browser removes these entries; clearing only the offline cache does not remove My Words.
Sharing a design
A current share link stores text and settings after the # character. That fragment is not normally sent to the web server, but it remains visible in browser history and to the recipient. Older links with sen in the query may appear in server access logs. Do not share a link with personal text more widely than intended.
Advertising, analytics, and network requests
The site may load Google AdSense and Google Analytics on normal online visits. These services can receive network information and use cookies according to browser settings and their policies. Our own feature events use the page language, tool type, and predefined settings, not your text, names, saved words, or full share links. Shared-state pages do not load those third-party scripts. We do not measure ad clicks ourselves. Blocking these services does not prevent the tools from working.

Offline storage
A service worker caches application pages, scripts, and the bundled fonts. This allows the main tools to work offline after setup. Browser storage limits, private browsing, or clearing the cache can make an online visit necessary again.
Contacting the operator
The contact form is different from the design tools: it sends the name, email address, subject, and message you submit to the operator by email. It uses a session token, IP-based rate limits, and a block list to reduce abuse. Server access and mail logs may also be retained by the hosting service. Avoid including sensitive information that is not needed for your inquiry.
Questions and controls
Use your browser’s site-data controls to remove local preferences and My Words. For questions about a contact submission, use the contact page. This page describes the site’s behavior; it does not promise that every device or third-party service stores data in the same way.
