Mood31

Privacy Policy

Last updated: 17 August 2026

Mood31 collects nothing. Everything you create stays on your device. There are no accounts, no servers, no analytics, and no advertising.

What we collect

Nothing. Mood31 does not collect, transmit, or store any personal information. We have no servers that receive your data, and no way to see what you put in the app.

Where your data lives

Everything you enter — calendar emoji, images, titles, and notes — is saved locally on your device only. This includes:

  • Emoji and images you add to individual dates
  • Calendar titles and handwritten annotations
  • Your language, font, and display preferences

This data never leaves your device unless you choose to export or share it yourself.

Photos

Mood31 has no permission to read your photo library, and cannot browse it.

When you add a photo to a date, iOS shows its own photo picker and hands Mood31 only the single image you chose. That image is then resized to a small thumbnail on your device and saved locally. The original photo is never copied or kept.

The one permission Mood31 does request is add-only access, so it can save a finished calendar image to your library when you ask it to. Add-only access lets an app write a photo; it does not let the app read anything.

Exporting and sharing

Mood31 can turn your calendar into an image. That image is created on your device. What happens to it afterwards is entirely up to you — if you share it, you are sharing it directly through the app or service you choose, not through us.

No network access

Mood31 makes no network requests at all. Fonts and every other resource are bundled inside the app. Even with a connection available, the app does not contact anything — which is also why it works identically offline.

No third parties

Mood31 contains no analytics tools, no advertising networks, no crash reporting services, and no third-party tracking of any kind. No third party receives information about you through this app.

Deleting your data

You can clear any individual date inside the app. To remove everything, delete Mood31 from your device — this permanently erases all data the app has stored. Because nothing is backed up to us, deleted data cannot be recovered.

Children

Mood31 is suitable for all ages and does not knowingly collect information from anyone, including children. Since the app collects no data at all, there is nothing for a child — or an adult — to disclose.

Changes to this policy

If this policy changes, the updated version will be posted on this page with a new date at the top. Meaningful changes will also be noted in the app's release notes.

Mood31 不收集任何信息。你创建的所有内容都保存在你自己的设备上。没有账号,没有服务器,没有数据分析,也没有广告。

我们收集什么

不收集任何信息。Mood31 不收集、不传输、不存储任何个人信息。我们没有接收你数据的服务器,也无法看到你在应用里放了什么。

你的数据存在哪里

你输入的一切 —— 日历 emoji、图片、标题、标注 —— 都只保存在你的设备本地,包括:

  • 你添加到某一天的 emoji 和图片
  • 日历标题和手写标注
  • 你的语言、字体和显示偏好

除非你自己选择导出或分享,这些数据不会离开你的设备。

照片

Mood31 没有读取相册的权限,也无法浏览你的相册。

当你给某一天添加照片时,由 iOS 弹出系统自己的照片选择器,只把你选中的那一张交给 Mood31。这张图片随后在你的设备上被压缩成小尺寸缩略图并保存在本地,原图不会被复制,也不会留下。

Mood31 唯一申请的权限是「仅添加」——用于在你需要时把做好的月历图片存进相册。「仅添加」权限只允许应用写入照片,不允许读取任何内容。

导出与分享

Mood31 可以把你的日历导出成图片。这张图片是在你的设备上生成的。之后如何处理完全由你决定 —— 如果你分享它,是通过你自己选择的应用或平台直接分享,不经过我们。

不联网

Mood31 完全不发起任何网络请求。字体和其他所有资源都打包在应用内部。即使有网络可用,应用也不会连接任何地方 —— 这也是它在离线状态下表现完全一致的原因。

没有第三方

Mood31 不含任何数据分析工具、广告网络、崩溃上报服务,也没有任何形式的第三方追踪。没有任何第三方能通过本应用获得关于你的信息。

删除你的数据

你可以在应用内清空任意某一天的内容。要删除全部内容,把 Mood31 从设备上卸载即可 —— 这会永久清除应用存储的所有数据。由于我们这边没有任何备份,删除后的数据无法恢复。

儿童隐私

Mood31 适合所有年龄使用,不会有意收集任何人的信息,儿童也不例外。由于本应用完全不收集数据,无论儿童还是成人,都不存在需要提交的信息。

本政策的变更

如果本政策有变更,更新后的版本会发布在本页,并在顶部标注新的日期。重要变更也会在应用的版本说明中提及。
