We strive not to collect any personal information — most features run entirely in your browser.

4 关于 CookieAbout cookies
本网站不使用 Cookie进行追踪或分析。我们只使用浏览器本地的 localStorage，它的作用范围仅限于你的浏览器，不会随网络请求发送，也不会被第三方读取。
This site does not use cookies for tracking or analytics. We only use browser localStorage, which stays within your browser, is never sent with network requests, and cannot be read by third parties.
因此，你不需要看到 Cookie 同意弹窗——因为我们没有需要征得同意的追踪行为。 That is why you will not see a cookie consent banner — there is no tracking to consent to.
5 如何删除你的数据How to delete your data
- 部分工具页面底部提供「清空本地数据」按钮，点击即可删除该工具保存的内容；具体以各工具页面为准
- Some tool pages provide a "Clear local data" button that removes what that tool saved; check each tool page for specifics
- 你也可以在浏览器设置中清除本站的站点数据
- You can also clear this site's data in your browser settings
- 清除后，我们这边没有任何备份可以恢复（因为从来就没有上传过）
- Once cleared, there is no backup on our side to restore (because nothing was ever uploaded)
