Privacy Policy

Effective November 2026 · Mist Oracle for Apple Vision Pro, iPhone and iPad · Developer: Geng Cui

Mist Oracle is a crystal ball for entertainment. We collect as little as possible: there is no account, no advertising, no analytics and no tracking.

Your voice

When you ask a question, Apple's speech recognition on your device turns your voice into text. Depending on your device and language, Apple may process the audio on its servers under Apple's privacy policy. We never receive or store audio.

AI answers

AI answers are optional and only used after you agree in the app. When they are on, the text of your question is sent over an encrypted connection to our server (hosted by Cloudflare), which asks Google Gemini for an answer and passes it back to you.

Our server does not store your questions or the answers.
Google processes the question to create the answer under the Gemini API terms and may keep it for a limited time to detect abuse.
You can turn AI answers off at any time in Settings (iPhone/iPad) or in the control panel (Vision Pro). The app then uses its built-in answers and sends no new questions. A question already sent may finish processing. Purchase and restore operations can still contact Apple.

What our server keeps

A random device key. On first use the app creates a key with Apple's App Attest, which proves requests come from the real app. Its random ID lets us count how many AI answers your device used today. It is not your name, Apple ID or advertising identifier, but it links usage and purchase records to this installation.
Daily counts. How many AI answers each device key used today. Older counts are deleted when the next question is processed. Daily cost totals and model-call accounting records contain no question text; records older than 31 days are cleaned up when the next question is processed.
Your unlock. If you buy "Unlock the Oracle", the App Store transaction ID is kept with your device key so the server knows you are unlocked. We retain these records and signed purchase-status timestamps to restore access and apply refunds or revocations. We never see your payment details: Apple handles payments.

Sharing

We do not sell your data or share it for advertising. We use the following service providers: Cloudflare (hosting our server), Google (creating AI answers) and Apple (speech recognition, App Attest and the App Store). Cards you share leave the app only through the system share sheet, to wherever you choose.

Technical operations and support

Our server records technical events such as the model used, response time and error codes to operate the service. These application logs do not include question text, answers, audio or purchase credentials. Hosting providers may process network information such as IP addresses and request metadata to deliver and protect the website and service. We do not add advertising or analytics scripts to this website.

If you email us, we use your email address and the information you choose to send to respond to your request.

Children

Mist Oracle is not directed at children under 13, and we don't knowingly collect information from them.

Your choices

Turn AI answers off to stop sending questions. Deleting the app removes everything stored on your device; server records are not automatically deleted when you uninstall. Device keys and purchase records are retained to provide and protect the service. To request deletion, contact us before uninstalling where possible; we will review whether the relevant installation or purchase can be identified. We cannot look up an installation from your name or email address alone. Please do not send your questions or payment details. Contact: gengcui123@gmail.com.

Changes

If this policy changes, we'll update this page and its date.

隐私政策

生效日期：2026 年 11 月 · 迷雾神谕（Apple Vision Pro、iPhone、iPad）· 开发者：Geng Cui

迷雾神谕是一款娱乐用的水晶球 app。我们尽可能少地收集信息：没有账号、没有广告、没有数据分析，也没有跟踪。

你的语音

你提问时，设备上的 Apple 语音识别会把语音转换成文字。视设备和语言而定，Apple 可能会在其服务器上处理音频，适用 Apple 的隐私政策。我们从不接收、也不保存任何录音。

AI 回答

AI 回答是可选的，只有你在 app 里同意后才会使用。开启后，问题的文字会通过加密连接发送到我们的服务器（由 Cloudflare 托管），服务器再请 Google Gemini 生成回答并返回给你。

我们的服务器不保存你的问题和回答。
Google 依据 Gemini API 条款处理问题以生成回答，并可能为防滥用短期保留。
你可以随时在设置（iPhone/iPad）或控制面板（Vision Pro）里关闭 AI 回答。关闭后 app 只用内置答案，不再发送新问题。已发送的问题可能仍会完成处理；购买和恢复购买仍可能联系 Apple。

服务器保存的内容

随机的设备密钥：第一次使用时，app 会通过 Apple 的 App Attest 生成一个密钥，用来证明请求来自正版 app。它的随机编号用来计算你的设备当天用了几次 AI 回答。它不是你的姓名、Apple ID 或广告标识符，但会将使用次数和购买记录关联到本次安装。
每日次数：每个设备密钥当天用了几次 AI 回答，旧记录会在之后收到下一次提问时清理。每日费用汇总和模型调用计费记录不包含问题文字，超过 31 天的记录也会在下一次提问时清理。
解锁记录：如果你购买了“解锁神谕”，App Store 的交易编号会和设备密钥一起保存，以便服务器确认你已解锁。我们保留这些记录和已签名购买状态的时间戳，以恢复解锁并处理退款或撤销。我们看不到付款信息，付款由 Apple 处理。

共享

我们不出售你的数据，也不为广告共享数据。参与处理数据的服务提供商包括：Cloudflare（托管服务器）、Google（生成 AI 回答）和 Apple（语音识别、App Attest 和 App Store）。你分享的卡片只会通过系统分享面板，发送到你自己选择的地方。

技术运维与客服

服务器会记录所用模型、响应时间、错误码等技术事件，以便维护服务。这些应用日志不包含问题文字、回答、录音或购买凭证。托管服务商可能会处理 IP 地址和请求元数据等网络信息，以提供和保护网页及服务。我们没有在网页中加入广告或数据分析脚本。

如果你发邮件给我们，我们会使用你的邮箱及你选择提供的信息来处理和回复请求。

儿童

迷雾神谕不面向 13 岁以下的儿童，我们也不会有意收集他们的信息。

你的选择

关闭 AI 回答即可停止发送问题。删除 app 会清除设备上的所有数据，卸载不会自动删除服务器记录。设备密钥和购买记录会为提供及保护服务而保留。如需申请删除，建议在卸载前联系我们；我们会核查能否识别相关安装或购买；仅凭姓名或邮箱无法查找某次安装。请不要发送你的问题或付款资料。联系邮箱： gengcui123@gmail.com。

变更

如果本政策有变更，我们会更新本页面及日期。
