照片留白 / Blanc · 最后更新 2026 年 7 月 25 日

一句话：照片留白不收集你的任何数据。它没有服务器、没有账号、不联网上传照片。所有照片和整理记录都只留在你自己的 iPhone 上。

我们收集什么

不收集。照片留白不含分析 SDK、不含广告、不含崩溃上报、不做用户画像，也不要求你注册或登录。我们无法看到你有哪些照片、删了哪些照片，因为这些信息从未离开你的设备。

照片如何被使用

• App 需要「照片」权限，才能把你相册里的照片显示成卡片供你左右滑动整理。这是它唯一的功能。
• 照片只在你的设备本地读取和显示，不会被上传、备份或传输到任何地方。
• 你确认删除时，App 调用 iOS 系统的标准照片删除接口。照片会进入系统相册的「最近删除」，30 天内你都可以自行恢复。App 不做真正的物理删除，也无法绕过这个系统机制。

本地保存了什么

为了实现「看过的照片不再重复推给你」这个核心功能，App 会在设备本地数据库里记录已处理过照片的系统标识符、处理结果（保留 / 已删除）、文件字节数与时间戳。这些记录：

• 只存在你的设备上，随 App 一起被 iOS 沙盒保护；
• 不含照片本身，也不含任何可识别你个人身份的信息；
• 可以在 App 的「设置 → 重置整理记录」里一键清空（此操作只清记录，不动你的相册）；
• 删除 App 即随之永久消失。

购买信息

解锁完整版通过 Apple 的 App 内购买完成。付款、账单与退款全部由 Apple 处理，我们不接触也不存储你的支付信息。App 仅通过 Apple 提供的机制在本地校验你是否已购买。

第三方

没有第三方。照片留白不集成任何第三方服务、SDK 或数据处理方，因此不存在数据共享或出售的情形。

儿童

照片留白不面向 13 岁以下儿童设计，也不会有意收集任何人的个人信息。

政策变更

如果这份政策有实质变更，我们会更新本页顶部的日期。由于 App 的设计前提是「不收集数据」，我们预计不会有削弱你隐私的变更。

常见问题

删掉的照片还能找回来吗？

能。照片留白走的是 iOS 系统的标准删除接口，被删的照片会进入系统「照片」App 的「最近删除」相簿，30 天内都可以自行恢复。我们不做也做不到不可逆的物理删除。

为什么同一张照片不会再出现？

这是核心设计。App 会在本地记住你处理过哪些照片，之后绝不重复推送——你的每一次滑动都不做重复劳动。想重新来一遍，可以在「设置 → 重置整理记录」清空记录（只清记录，不动相册）。

我的照片会被上传吗？

不会。App 没有服务器也不联网传输照片，全部处理都在你的设备本地完成。详见隐私政策。

左滑右滑分别是什么？

左滑 = 保留，右滑 = 删除。拖动过程中会浮现对应的印章提示。不想滑的话，底部按钮也能完成同样的操作，还有撤销。

删除是立刻发生的吗？

不是。滑动只是先把照片放进「待删」队列。滑完一局会进入复核页，你可以平铺检查、把任何一张捞回来，确认之后才由系统一次性删除。

免费能用多少？

累计删除 100 张之前完全免费。之后需要一次性买断解锁，永久有效、没有订阅。

换了新手机，整理记录会跟过去吗？

当前版本记录只存在本机，换机或重装后需要重新开始。跨设备同步在后续版本的计划中。

我买过了，换设备后怎么恢复？

在「设置 → 恢复购买」里用原来的 Apple ID 恢复即可，不需要再次付费。

支持 iPad 吗？

照片留白是为 iPhone 竖屏单手操作设计的。iPad 上可以安装并以 iPhone 兼容模式运行，但界面未针对大屏优化。

Privacy Policy

Blanc · Last updated 25 July 2026 · 中文版

In one line: Blanc collects no data about you. There is no server, no account, and no upload. Your photos and your tidying history never leave your iPhone.

What we collect

Nothing. Blanc contains no analytics SDK, no advertising, no crash reporting, and no profiling, and it never asks you to register or sign in. We cannot see which photos you have or which ones you deleted, because that information never leaves your device.

How your photos are used

• Blanc requests Photos access so it can show the photos in your library as cards for you to swipe through. That is its only purpose.
• Photos are read and displayed locally on your device and are never uploaded, backed up, or transmitted anywhere.
• When you confirm a deletion, Blanc calls the standard iOS photo deletion API. Deleted photos go to the system "Recently Deleted" album, where you can restore them yourself for 30 days. Blanc does not perform, and cannot perform, an irreversible deletion, nor can it bypass this system mechanism.

What is stored on your device

To deliver the core feature — a photo you have already reviewed is never shown to you again — Blanc records, in a local on-device database, the system identifier of each photo you have handled, the outcome (kept / deleted), the file size in bytes, and a timestamp. These records:

• exist only on your device, protected by the iOS sandbox along with the app;
• contain no photo content and nothing that personally identifies you;
• can be cleared at any time via Settings → Reset tidying history (this clears the records only; it does not touch your photo library);
• are permanently gone when you delete the app.

Purchases

The full version is unlocked through Apple's In-App Purchase. Payment, billing, and refunds are handled entirely by Apple; we neither see nor store your payment information. Blanc only verifies your purchase locally through the mechanism Apple provides.

Third parties

There are none. Blanc integrates no third-party service, SDK, or data processor, so there is no sharing or selling of data to speak of.

Children

Blanc is not designed for children under 13, and does not knowingly collect personal information from anyone.

Changes to this policy

If this policy changes materially, we will update the date at the top of this page. Because the app is built on the premise of collecting no data, we do not anticipate changes that weaken your privacy.

Frequently asked questions

Can I get deleted photos back?

Yes. Blanc uses the standard iOS deletion API, so deleted photos go to the "Recently Deleted" album in the system Photos app, where you can restore them for 30 days. We do not — and technically cannot — delete anything irreversibly.

Why does the same photo never come back?

That is the core design. Blanc remembers locally which photos you have already handled and never shows them again, so no swipe is ever wasted work. To start over, clear the records in Settings → Reset tidying history (records only; your library is untouched).

Are my photos uploaded?

No. Blanc has no server and transmits no photos; everything happens locally on your device. See the Privacy Policy.

What do left and right swipes do?

Swipe left to keep, swipe right to delete. A matching stamp appears as you drag. If you would rather not swipe, the buttons along the bottom do the same thing, and there is an undo.

Does deletion happen immediately?

No. Swiping only puts a photo into a pending queue. At the end of each round you get a review screen where you can see everything laid out and pull any photo back; only after you confirm does the system delete them in one batch.

How much is free?

Everything is free until you have deleted 100 photos in total. After that a one-time purchase unlocks unlimited use — permanent, with no subscription.

If I switch phones, does my tidying history follow?

In the current version the history is stored only on the device, so you start fresh after switching phones or reinstalling. Cross-device sync is planned for a later version.

I already bought it — how do I restore on a new device?

Use Settings → Restore purchase with your original Apple ID. There is no need to pay again.

Is iPad supported?

Blanc is designed for one-handed portrait use on iPhone. It can be installed and run on iPad in iPhone compatibility mode, but the interface is not optimised for the larger screen.
