二维码链接识别：隐私政策
版本 1.0.6 · 更新日期：2026-09-19
本政策适用于“二维码链接识别”（QR Link Jumper）Chrome 扩展。发布者为 Chrome 网上应用店中该扩展详情页列明的开发者。隐私问题与支持联系邮箱：coco0166@hotmail.com。
处理哪些信息
扩展读取获准访问网页中图片和画布的像素、图片地址及显示位置，在设备上的扩展代码中解码二维码。仅对 HTTP/HTTPS 网页链接显示打开、复制和关闭按钮。不请求摄像头，不读取剪贴板，不建立浏览历史记录，不包含广告、分析统计或开发者服务器上传功能。
网络请求与第三方
网页不允许直接读取图片像素时，扩展后台可能向图片原始地址发起请求并跟随重定向，然后在本机解码；请求不携带登录凭据（credentials: omit）。图片服务商及重定向后的服务商会像正常网络请求一样接收 IP 地址、图片 URL 和常规请求信息。URL 自带的查询参数仍随请求发送。HTTP 图片请求本身不加密。我们不将图片或解码结果上传至开发者经营的服务器或第三方识别服务。
点击“打开”后，浏览器访问目标网站，其隐私政策适用。点击“复制”后，完整链接写入系统剪贴板；其他具备剪贴板读取能力的软件可能读取它。扩展不会自动访问识别到的目标链接。
存储、保留与删除
自动识别开关和新标签页设置保存在 chrome.storage.sync，可在用户启用 Chrome 同步时由 Google 同步。二维码内容和源图片地址不写入该同步存储。后台最多缓存 120 条图片解码记录于内存，缓存有效期为 10 分钟；过期记录在访问时失效，可能保留到缓存淘汰或后台进程结束。页面提示与关闭状态保留于页面内存，刷新页面后重置。浏览器可能按自身规则缓存下载的图片。
可关闭自动识别、在 Chrome 扩展设置中限制网站访问或卸载扩展。刷新页面可清理该页面的识别状态；系统剪贴板、Chrome 图片缓存及同步数据由对应系统或 Google 设置管理，卸载扩展不代表同时清除这些外部副本。
用途与变更
所处理信息仅用于识别二维码和执行用户的打开、复制操作。我们不出售数据，不用于广告、信用评估或无关用途。使用从 Google API 获得的信息将遵守 Chrome 网上应用店用户数据政策，包括 Limited Use 要求。未来如增加收费、账号或新的数据处理方式，将先更新本政策并按要求提供披露和同意流程。当前版本无需账号、免费使用；不提供恶意网址检测或安全保证。
QR Link Jumper: Privacy Policy
Version 1.0.6 · Updated September 19, 2026
This policy applies to the Chrome extension named 二维码链接识别 (QR Link Jumper). The publisher is the developer identified on its Chrome Web Store listing. For privacy questions and support, contact coco0166@hotmail.com.
Information processed
The extension reads image/canvas pixels, image URLs and display positions on permitted web pages to decode QR codes on your device. It displays open, copy and dismiss controls for HTTP/HTTPS links only. It does not request camera access, read your clipboard, create browsing-history records, include ads or analytics, or upload data to a developer-operated server.
Network requests and third parties
If pixels cannot be read directly, the extension may fetch the source image and follow redirects, then decode it locally. These requests omit login credentials (credentials: omit). Image hosts and redirected hosts receive your IP address, requested image URL and normal request information. Query parameters embedded in the image URL are still transmitted. HTTP image requests are not encrypted. Images and decoded results are not uploaded to a developer-operated server or third-party decoding service.
Opening a link visits its destination, whose privacy policy applies. Copying writes the full URL to the system clipboard, which other applications with clipboard access may read. Decoded destinations are not visited automatically.
Storage, retention and controls
Automatic scanning and new-tab preferences are stored in chrome.storage.sync and may be synchronized by Google when Chrome sync is enabled. QR contents and source image URLs are not written to sync storage. Up to 120 image decoding records are cached in background memory with a 10-minute validity period. Expired records become invalid on access but may remain in memory until eviction or background-process termination. Page overlays and dismissal state reside in page memory and reset on reload. Chrome may cache downloaded images under its own rules.
You can disable scanning, restrict site access in Chrome or uninstall the extension. Reloading clears page recognition state. The system clipboard, browser image cache and synced data are managed by the operating system or Google settings; uninstalling does not necessarily clear those external copies.
Purpose and changes
Information is used only to recognize QR codes and perform user-requested open/copy actions. We do not sell data or use it for advertising, credit decisions or unrelated purposes. The use of information received from Google APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements. Before introducing payments, accounts or new data practices, this policy will be updated and required disclosures and consent provided. This version is free and requires no account. It does not detect malicious destinations or guarantee link safety.
