Arcula：照片与视频的私密空间
Arcula: a private space for photos and videos
从本地加密、文件夹整理到伪装密码、私密相机与加密备份，让照片和视频有一个由你掌管的私密空间。
From local encryption and folder organization to Decoy Passcode, Private Camera, and Encrypted Backup, give your photos and videos a private space you control.
把照片与视频保存在自己的私密空间
Arcula 是一款适用于 iPhone 和 iPad 的私密相册，支持照片、视频、实况照片和 GIF。导入的媒体在设备本地加密保存，不需要注册账户，也不自动同步到 iCloud 或开发者服务器。
你可以把希望单独保存的内容集中到这里，按文件夹整理，再根据使用习惯设置解锁方式、导入偏好和浏览方式。
从相册、文件或浏览器导入
“从照片导入”可以选择系统相册中的媒体，并将它们放入指定文件夹；实况照片会保留照片与对应的动态内容。“从文件导入”则适合已经保存在“文件”、外接存储或文件提供者中的照片和视频。
照片在电脑上时，可以打开“浏览器导入”，让两台设备连接同一 Wi-Fi，再在电脑浏览器中输入 Arcula 显示的地址和认证信息，直接上传内容。导入时还可以跳过重复内容，减少反复整理。
如果希望在导入后删除系统相册原件，可以在设置中开启对应选项，并在系统提示中确认。删除前请先检查导入结果；系统相册的“最近删除”仍可能保留原件，需要单独管理。
用文件夹整理，用喜欢的方式浏览
媒体可以放进不同文件夹，也可以通过收藏标记常看的内容。多选后，能够批量移动、收藏、导出或删除，让一次整理覆盖多张照片和视频。
浏览时，可以按拍摄时间、导入时间或文件大小排序，调整网格密度，或使用幻灯片播放连续查看内容。幻灯片支持调整播放间隔与随机顺序，配合浅色和深色外观，适应不同的浏览习惯。
为 App 和文件夹设置保护
“启动验证”用于设置打开 Arcula 时的解锁方式，可以使用启动密码，或设备支持的 Face ID / Touch ID。需要进一步分开管理的内容，可以放进加密文件夹，为文件夹设置独立的访问保护。
进入后台时，Arcula 会遮挡任务切换预览，避免相册内容直接显示在 App 切换界面中。你也可以启用扣下手机锁定，在需要时快速锁住私密空间。
生物识别验证由系统完成，Arcula 不会获取或保存面部与指纹模板。
伪装密码、图标与入侵记录
“伪装密码”可以打开一个独立的伪装空间，让真实相册保持隐藏。它与启动密码不同，也不会删除真实内容。你还可以更换 App 图标，选择计算器、便签、天气或指南针等外观。
“入侵记录”用于查看错误解锁等事件。开启“入侵拍照”并授予相机权限后，App 可以根据设置的触发条件，用前置摄像头拍照并加密保存在本机。是否能够拍摄取决于权限、相机状态和相关设置。
用私密相机直接拍摄
“私密相机”可以将拍摄的照片和视频直接保存到加密相册，无需先放进系统相册再导入。录制带声音的视频时，需要麦克风权限。
这适合希望从拍摄开始就单独保存的内容，也能减少在不同相册之间搬运的步骤。
导出到需要的地方
需要取出内容时，可以保存到系统相册，或通过系统分享交给其他 App。“导出到其他设备”则让同一 Wi-Fi 下的电脑或其他设备通过浏览器下载媒体。
浏览器传输使用本地 HTTP，请在可信网络中使用，并在完成后关闭传输页面。导出的普通媒体文件不再受 Arcula 保险箱加密保护，保存位置和接收设备需要由你自行管理。
最近删除与加密备份
启用“最近删除”后，删除的内容会先保留 30 天，方便在永久清理前恢复误删项目；关闭该功能时，删除会直接永久移除内容。
“加密备份”可以把当前空间的媒体和文件夹打包成备份文件，保存到“文件”、电脑或外接存储，再通过“从备份恢复”导入。备份前需要解锁希望包含的加密文件夹，并检查被跳过的内容；“最近删除”中的项目不包含在备份中。
备份密码可以留空，但留空时，任何拿到文件的人都能恢复其中的内容。建议设置密码并妥善保管；Arcula 不保存备份密码，开发者也无法帮你找回。
Arcula 的媒体库和密钥不参与 iCloud 同步或设备备份。卸载 App 会删除本地私有空间，请在换机或卸载前导出所需内容，或保存并核实有效备份。

Keep photos and videos in your own private space
Arcula is a private photo vault for iPhone and iPad that supports photos, videos, Live Photos, and GIFs. Imported media is encrypted on your device. No account is required, and the library does not automatically sync to iCloud or developer-operated servers.
Bring together content you want to keep separately, organize it into folders, and choose the unlocking, importing, and browsing settings that suit you.
Import from Photos, Files, or a browser
Import from Photos lets you select media from your photo library and place it in a destination folder. Live Photos retain both the still image and its accompanying motion. Import from Files works with photos and videos already stored in Files, external storage, or a file provider.
For photos on a computer, open Browser Import and connect both devices to the same Wi-Fi network. Enter the address and credentials shown in Arcula into the computer’s browser to upload content directly. You can also skip duplicates during import to reduce repeated organization.
To delete originals from Photos after importing, enable the corresponding setting and confirm the system prompt. Check the imported content before deleting originals. Photos may still retain those originals in its own Recently Deleted album, which you manage separately.
Organize with folders and browse your way
Place media in different folders and mark frequently viewed items as favorites. Select multiple items to move, favorite, export, or delete them together.
Sort by capture date, import date, or file size, adjust the grid density, or use Slideshow to browse content continuously. Adjustable intervals and shuffle, alongside light and dark appearance, let you choose how to view your library.
Protect the app and individual folders
Unlock Method controls how you open Arcula, using an app passcode or supported Face ID / Touch ID. For content that needs separate access protection, use encrypted folders.
When Arcula enters the background, it shields the app switcher preview so your library is not directly visible there. You can also enable locking when you place your phone face down to quickly lock your private space.
Biometric authentication is handled by the system. Arcula does not access or store facial or fingerprint templates.
Decoy Passcode, icons, and Intruder Log
Decoy Passcode opens a separate decoy space while keeping your real library hidden. It differs from your app passcode and does not delete your real content. You can also use Change Icon to choose an appearance such as a calculator, notes, weather, or compass app.
Intruder Log lets you review events such as failed unlock attempts. With Intruder Photos enabled and camera permission granted, the app can take front-camera photos under your configured conditions and store them encrypted on your device. Capture availability depends on permissions, camera state, and your settings.
Capture directly with Private Camera
Private Camera saves captured photos and videos directly into the encrypted library, without first adding them to Photos and importing them afterward. Recording video with sound requires microphone permission.
It is a convenient way to keep content separate from the moment you capture it, with fewer steps between libraries.
Export where you need it
Save media to Photos or send it to another app through the system share sheet. Export to Other Devices lets a computer or another device on the same Wi-Fi network download media through a browser.
Browser transfers use local HTTP. Use a trusted network and close the transfer screen when finished. Ordinary exported media files are outside Arcula’s vault encryption, so you manage the destination and recipient device yourself.
Recently Deleted and Encrypted Backup
With Recently Deleted enabled, deleted content is retained for 30 days so you can recover mistakes before permanent cleanup. With the feature disabled, deletion removes content permanently right away.
Encrypted Backup packages media and folders in the current space into a backup file. Save it to Files, a computer, or external storage, then import it using Restore from Backup. Unlock encrypted folders you want to include before creating the backup and review any skipped content. Recently Deleted items are excluded.
The backup password can be empty, but anyone holding that file can then restore its contents. Set a password and keep it safe. Arcula does not save backup passwords, and the Developer cannot recover them for you.
Arcula’s library and keys are excluded from iCloud sync and device backups. Deleting the app removes its local private space. Export the content you need or save and verify a valid backup before switching devices or deleting the app.
