隐私政策
19长截图由独立开发者品牌 SHIJIU STUDIO 提供。当前版本在 iPhone 本机采样和拼接滚动画面。
1. 屏幕内容与本机存储
当你在 iOS 系统录屏选择列表中选择“19长截图”并开始共享后，录屏扩展抽取部分屏幕画面并将 JPEG 帧保存在 App 与扩展共用的本机空间。停止后，主 App 在本机拼接为 PNG 长图。扩展不录音、不生成录屏视频，也不把画面上传到开发者服务器。
当前 App 不要求注册账号，不集成广告、用户追踪、第三方行为分析或开发者运营的云同步。录制会话和生成的长图可能继续保留在 App 本机数据中；当前版本尚无单独的历史录制清理界面。设备备份是否包含这些数据取决于你的 iOS 备份设置。
2. 相册、分享与删除
只有你点击“保存到相册”并授权后，App 才将结果写入系统照片图库。你使用系统分享功能时，所选文件会交给你指定的 App 或文件位置，其处理方式由相应服务决定。卸载 App 会移除其本机数据；已保存到相册或导出到其他位置的副本需在那里自行删除。系统备份中的数据由 Apple 的备份机制管理。
3. 支持网站与联系
公开支持页面托管于 GitHub Pages；访问该网页时，GitHub 可能按其政策处理网页访问数据。这与 App 自动上传屏幕画面无关。你主动发送支持邮件或加入 QQ 群时，相应服务会处理你提供的邮箱地址、消息或群资料。请勿发送未经遮挡的私人屏幕内容。联系邮箱：shijiuhan19@gmail.com。
4. 变更
如后续加入联网、账号、分析、内购或改变数据处理方式的功能，我们会在发布前更新本政策及 App Store 隐私申报。
19 Long Screenshot Privacy Policy
1. Screen content and local storage
When you select “19长截图” in the iOS screen recording picker and start sharing, the broadcast extension samples some screen frames and stores JPEG files in an on-device container shared with the app. After recording stops, the app stitches them into a PNG on your device. The extension does not record audio, create a screen recording video, or upload screen content to our servers.
The current app requires no account and includes no ads, tracking, third-party behavioral analytics, or developer-operated cloud sync. Capture sessions and generated images may remain in the app's on-device data. There is currently no separate in-app history cleanup screen. Inclusion in device backups depends on your iOS backup settings.
2. Photos, sharing, and deletion
The app writes an image to Photos only when you choose Save to Photos and authorize it. When you share an image, iOS passes it to the app or file location you select, which handles it under its own terms. Uninstalling the app removes its local app data. Copies saved to Photos or exported elsewhere must be deleted there separately. Apple manages data in system backups.
3. Website and contact
The public support site is hosted by GitHub Pages, which may process site visit data under its policies. Visiting the site does not mean the app automatically uploads screen content. If you email support or join the optional QQ group, the relevant service processes the information you choose to provide. Redact private screen content before sending it. Contact shijiuhan19@gmail.com for privacy questions.
4. Updates
Before releasing features that change data handling, including networking, accounts, analytics, or purchases, we will update this policy and the App Store privacy answers.
