English
FlowMaker is an on-device utility for turning screenshots into shareable flow images. The app is designed to work offline-first and to keep your media on your device.
What FlowMaker does
- Uses PhotoKit to discover recent screenshots when you allow photo access.
- Lets you manually choose screenshots with the iOS Photos picker.
- Renders a flow image locally on your device.
- Saves the exported image to Photos only when you choose Save PNG.
- Stores the active draft locally. Generated flow images and thumbnails are kept in local history for up to 30 days.
What FlowMaker does not do
- No account system.
- No backend upload of your screenshots or exported images.
- No analytics SDK, advertising SDK, tracking SDK, or cross-app tracking.
- No AI model or AI service receives your screenshots.
- No silent deletion or modification of your media.
Photo access
FlowMaker requests photo access only to help you find and select screenshots. You can use full access, limited access, or the system Photos picker. Add-only Photos access is requested only when you explicitly choose Save PNG. FlowMaker does not upload your media to a developer-operated server. If a selected asset is stored in iCloud Photos, Apple Photos may download it according to your device and iCloud settings.
Local storage
FlowMaker stores the active draft and app-managed image files in its local app container. Generated flow images and thumbnails are kept in local history. History items older than 30 days are removed the next time FlowMaker launches or opens history.
Before Pro is unlocked, FlowMaker stores the number of successful free flow generations in the device Keychain. This device-only count is used to enforce the three-free-generation limit. It does not sync to another device, but it may remain after FlowMaker is deleted and reinstalled.
Deleting FlowMaker removes its local draft and flow history. PNG files that you explicitly saved to Photos remain in your photo library until you delete them there.
Purchases
FlowMaker includes three successful free flow generations at full quality with no watermark. FlowMaker Pro is an optional, non-consumable, one-time App Store purchase that unlocks unlimited additional flow generation. It is not a subscription and has no recurring charge.
Apple StoreKit handles purchases and restoration using your Apple Account. FlowMaker queries the Pro entitlement from Apple and does not receive your payment card information or Apple Account credentials. Deleting the app does not erase the Apple-managed purchase; it can be restored with the same Apple Account.
App Store privacy summary
Based on the current app behavior, FlowMaker does not collect personal data, does not track users, does not use AI services, and processes screenshots and generated flows locally on device. App Store purchases are processed separately by Apple.
Changes to this policy
If FlowMaker changes how it handles data, this page will be updated before the next release.

FlowMaker 是一个在设备本地把截图整理成流程图的工具。产品默认离线工作， 尽量把你的素材留在本机。
FlowMaker 会做什么
- 在你授权后，通过 PhotoKit 查找最近的截图。
- 支持使用 iOS 照片选择器手动选择截图。
- 在你的设备本地生成流程图图片。
- 只有在你点击“保存 PNG”时，才会把导出图片写入相册。
- 在本机保存当前草稿，并将生成的流程图和缩略图在本地历史记录中保留最多 30 天。
FlowMaker 不会做什么
- 不提供账号系统。
- 不会上传你的截图或导出图片到服务器。
- 不使用分析 SDK、广告 SDK、跟踪 SDK，也不进行跨 App 跟踪。
- 不使用 AI 模型，也不会把你的截图发送给 AI 服务。
- 不会在未经你确认的情况下删除或修改你的媒体文件。
照片权限
FlowMaker 申请照片权限只是为了帮助你查找并选择截图。你可以授予完整访问、 受限访问，或使用系统照片选择器。只有当你主动点击“保存 PNG”时，App 才会 申请“仅添加照片”权限。FlowMaker 不会把你的媒体文件上传到开发者运营的 服务器。如果所选素材存储在 iCloud 照片中，Apple 照片可能会按照你的设备和 iCloud 设置下载该素材。
本地存储
FlowMaker 会在 App 的本地容器中保存当前草稿和由 App 管理的图片文件。生成的 流程图和缩略图会保存在本地历史记录中。超过 30 天的历史项目会在 FlowMaker 下次启动或打开历史记录时被清理。
在解锁 Pro 前，FlowMaker 会把免费成功生成次数保存在设备钥匙串中。该计数仅 属于当前设备，用于执行 3 次免费生成限制，不会同步到其他设备，但在删除并重新 安装 FlowMaker 后仍可能保留。
删除 FlowMaker 会移除本地草稿和流程历史。你主动保存到照片图库的 PNG 文件会 继续保留，直到你在照片 App 中将其删除。
内购
FlowMaker 提供 3 次全质量、无水印的免费成功生成。FlowMaker Pro 是可选的 非消耗型一次性 App Store 内购，可解锁不限次数的后续流程图生成；它不是订阅， 不会产生周期性扣费。
购买和恢复由 Apple StoreKit 按你的 Apple 账户处理。FlowMaker 会向 Apple 查询 Pro 权益，但不会获取你的银行卡信息或 Apple 账户凭据。删除 App 不会删除由 Apple 管理的购买记录，你可以使用同一 Apple 账户恢复购买。
App Store 隐私说明
基于当前版本行为，FlowMaker 不收集个人数据、不跟踪用户、不使用 AI 服务， 并在设备本地处理截图和生成的流程图。App Store 购买由 Apple 单独处理。
政策更新
如果 FlowMaker 未来改变数据处理方式，本页面会在下一次发布前更新。
