相册、相机和保存权限

权限或能力	使用方式
照片选择器	当你主动选择来源图片时使用。拾纹只接收你选中的图片，用于生成纹样。
相机	当你点击拍照时请求，用于拍摄纹样来源图。拾纹不会在后台调用相机。
添加到照片	在 iPhone / iPad 上把 PNG、JPG、TIFF（含样机 PNG）写入系统照片时请求。PDF 和 PSD 不走相册。
文件保存	Mac 上所有导出都写到你选择的位置。iPhone / iPad 上的 PDF、PSD，以及相册权限被拒绝后的「存储到文件」，同样由系统文件面板保存，不经过照片图库。
系统分享	当你点击分享时打开。作品只会发送到你选择的 App、联系人或服务。

你可以在系统设置中查看或撤销这些权限。撤销权限只会影响对应功能。

2.3.0 印刷导出、格式与样机

下载页可导出单位图块或整图。曼陀罗、螺旋是构图，只有整图，没有单位图块。
默认 DPI 为 300，写入你保存的文件（PNG、JPG、TIFF 的文件头，PSD 的分辨率信息；PDF 用它决定页面物理尺寸）。单位图块、自定义和社交媒体尺寸里，改 DPI 只改物理尺寸和文件信息，不改像素；纸张（A3 / A4 等）保持印刷物理尺寸，改 DPI 会改像素。
下载格式为 PNG、JPG、PDF、PSD、TIFF，没有 SVG，每次进入下载页默认 PNG。JPG 和 PDF 会把抠图留下的透明区域填成白色。画廊里的「保存」仍是 PNG。
非会员：取样输出最高 2048 px；单位图块和整图不能改宽高与 DPI；整图只能在 3:4 / 9:16 / 16:9 / 4:3 之间切换；可下载 PNG 和 JPG。Pro 可将取样输出调到 5000 px，选择纸张、社交媒体其余预设或自定义尺寸，并下载 PDF、PSD、TIFF。
编辑器预览仍是拖动 384 px、松手 1024 px；下载按你选的像素重新渲染，不是把预览图放大。
个人中心可填写最多 20 个字符的水印签名。下载页水印开关默认关闭，且只在选择 PNG 或 JPG 时出现；打开后只在本机盖到当前预览和这两种导出上。PDF、PSD、TIFF 不含水印。
样机在本机把纹样贴到 App 自带的产品照片上，不上传你的图片。样机下载只有 PNG，不加水印。iPhone / iPad 写入照片，Mac 走系统保存面板。

数据存储说明

当前版本无需注册或登录。
你选择的图片、抠图结果、生成的纹样、样机成图、画廊项目和水印签名默认保存在设备本地，不会上传到拾纹服务器。风格处理、抠图、AI 高清、印刷尺寸换算、格式编码、样机合成和高清导出也在设备上完成。
内购由 Apple StoreKit 处理；匿名产品分析使用 PostHog。这些服务不会收到你的来源图或纹样。
本地项目会保留到你在画廊中删除，或卸载 App。水印签名会保留到你在个人中心改掉或清空，或卸载 App。
已保存到系统照片、Mac 文件或其他服务的副本，需要在相应位置单独删除。
如果设备启用了系统备份，Apple 可能依据你的 iCloud 和设备备份设置备份 App 数据。

English Version

Shiwen is a creative pattern design tool for discovering pattern inspiration in everyday images.

A photo, a window, a piece of fabric, or even a casual doodle can become the starting point for a new design. Shiwen helps transform familiar materials into unique motifs and patterns, letting you explore new visual possibilities through variation and order.

Photos, camera, and saving permissions

Permission or feature	How it is used
Photo picker	Used when you choose a source image. Shiwen receives only the images you select and uses them to create patterns.
Camera	Requested when you choose to take a source photo. Shiwen does not access the camera in the background.
Add to Photos	On iPhone and iPad, requested when a PNG, JPG, or TIFF — including a mockup PNG — is written to Photos. PDF and PSD do not use the photo library.
File save	On Mac, every export is written to a location you choose. On iPhone and iPad, PDF and PSD use the system file panel, as does “Save to Files” after Photos permission is denied.
System share sheet	Opened when you choose Share. Your work is sent only to the app, person, or service you select.

You can review or revoke these permissions in system Settings. Revoking a permission affects only the related feature.

2.3.0 print export, formats, and mockups

The download page can export a unit tile or a full image. Mandala and Spiral are compositions: full image only, no unit tile.
Default DPI is 300 and is written into the file you save (the PNG, JPG, and TIFF headers, the PSD resolution resource; PDF uses it for the page’s physical size). For unit tiles, custom sizes, and social presets, changing DPI changes physical size and that file information, not pixels. Paper sizes (A3 / A4 and similar) keep their print dimensions; changing DPI changes pixels.
Download formats are PNG, JPG, PDF, PSD, and TIFF. There is no SVG. Each visit to the download page starts on PNG. JPG and PDF fill transparent cutout areas with white. Save to Gallery is still PNG.
Without Pro: sampling output tops out at 2048 px; unit-tile and full-image width, height, and DPI cannot be changed; full image can only switch among 3:4 / 9:16 / 16:9 / 4:3; downloads can be PNG or JPG. Pro can raise sampling output to 5000 px, choose paper, the remaining social presets, or a custom size, and download PDF, PSD, or TIFF.
Editor preview still uses 384 px while dragging and 1024 px when settled. Downloads re-render at the pixels you chose; they are not an upscale of the preview.
Profile can store a watermark signature of at most 20 characters. The download-page watermark switch is off by default and appears only for PNG and JPG. When on, the stamp is applied on-device to the current preview and those two exports. PDF, PSD, and TIFF are not watermarked.
Mockups composite your pattern onto product photos shipped inside the app. That composite stays on the device. A mockup download is PNG only, with no watermark: Photos on iPhone and iPad, the system save panel on Mac.

Data storage

The current version does not require an account or sign-in.
Selected images, cutouts, generated patterns, mockup composites, Gallery projects, and the watermark signature are stored locally on your device by default and are not uploaded to Shiwen servers. Style processing, cutout, AI HD, print-size calculation, format encoding, mockup compositing, and HD export also run on-device.
In-app purchases are processed by Apple StoreKit. Anonymous product analytics use PostHog. These services do not receive your source images or patterns.
Local projects remain until you delete them in Gallery or uninstall the app. The watermark signature remains until you change or clear it in Profile, or uninstall the app.
Copies saved to Photos, a Mac file, or another service must be deleted separately from those destinations.
If system backup is enabled, Apple may back up app data according to your iCloud and device backup settings.
