隐私与数据清除说明Privacy and data-clearing policy
这是一份写给普通用户看的说明：你的图片去了哪里、停留多久、以及怎么立刻把它清掉。In plain language: where your images go, how long they stay, and how to wipe them instantly.
1. 你的图片存在哪里1. Where your images live
只存在于当前页面的 JavaScript 内存（Canvas 与 ImageBitmap）中。我们不使用 localStorage、sessionStorage、IndexedDB 或文件系统保存任何图片内容，也没有上传接口可以把图片发走。刷新页面、关闭标签页或跳转到其它页面，内存即被释放。Only in the memory of this page (Canvas and ImageBitmap). We do not use localStorage, sessionStorage, IndexedDB or the file system to keep image content, and there is no upload endpoint that could send it anywhere. Reloading, closing the tab or navigating away releases it.
2. 自动清除规则2. Auto-clear rules
| 触发条件Trigger | 行为Behaviour |
|---|---|
| 30 分钟无任何操作（鼠标、触摸、键盘、滚动）30 minutes without any interaction | 清空内存图片与水印，回收对象链接，清理本站可用的浏览器存储与缓存；页面回到初始空白状态，并弹出提示。In-memory images and watermarks are removed, object URLs revoked, this site's browser storage and caches purged; the page returns to an empty state with a notice. |
| 页面切到后台（切换标签页 / 最小化）持续 1 分钟Page hidden in the background (tab switch / minimise) for 1 minute | 自动清空内存图片与水印并回收链接；提前回到页面则取消清除。后台定时器可能被浏览器节流，回到前台时会立即校准执行并提示。In-memory images and watermarks are cleared automatically and links revoked; returning before the minute is up cancels it. Background timers may be throttled by the browser, so the check also recalibrates the moment you come back, with a notice. |
| 关闭或刷新页面Closing or reloading | 浏览器直接释放内存；页面在卸载前还会尽力回收 Blob 链接并清理会话存储。The browser frees memory outright; before unload the page also revokes object URLs and clears session storage. |
| 倒计时最后 60 秒Final 60 seconds | 底部状态条变黄并提示剩余时间，任意操作都会重置计时，避免你正在编辑时被打断。The status bar turns amber with the remaining time; any interaction resets the timer so editing is never interrupted. |
| 点击「彻底清除」Pressing “Erase everything” | 立即执行完整清理：内存数据、Blob URL、localStorage、sessionStorage、IndexedDB、CacheStorage、Service Worker 注册，并可选清除语言等界面偏好。Full purge at once: memory, object URLs, localStorage, sessionStorage, IndexedDB, CacheStorage, service-worker registrations, optionally UI preferences such as language. |
3. 我们使用的少量本地设置3. The few local settings we keep
idmark.lang：你手动选择的界面语言（中文 / English）。默认按浏览器语言判断，浏览器语言为中文（含繁体）时显示中文，其它语言显示英文。idmark.lang: your UI language choice. By default we detect it from your browser - Chinese (including Traditional) shows 中文, anything else shows English.
设置里不含任何图片、文件名或文字内容；「彻底清除」默认会把它一起清掉。No images, file names or text content live there, and the erase action removes it by default.

5. 传输与托管5. Transport and hosting
页面与脚本通过 Cloudflare Pages 以 HTTPS 分发，托管方会记录常规的访问日志（IP、User-Agent 等技术信息），这与你的图片无关——图片从未离开你的设备。请自行确保在合法、授权的范围内使用水印与打码功能。Pages and scripts are served over HTTPS by Cloudflare Pages, which keeps ordinary access logs (IP, user agent). That has nothing to do with your images, which never left your device. Please use watermarking and masking lawfully and with proper authorisation.
