Privacy Policy
Effective date: 2026-10-15
Crown Logic ("the App") is developed by yinqiaoyin ("we"). This policy explains what data the App uses and why. We built the App to work without an account and to collect as little as possible.
1. Data we collect
| Data | Purpose | Linked to you? |
|---|---|---|
| A random, anonymous device ID created by the App | To accept your daily puzzle results and show your ranking | No — it is not connected to your name, email, Apple ID or advertising ID |
| Daily puzzle results (solve time, hints used, conflicts, undo count, completion time and time zone offset) | To calculate daily percentiles and time distributions shown in the App | No |
| Badge unlocks (badge ID, tier, time) | To show how many players earned each badge | No |
| App opens (date only) | To count daily active players | No |
| Feedback you send (message, optional email, app/device info) | To respond and fix issues | Not used for tracking |
| Basic technical info (app version, platform, language, time zone) | To serve the right daily puzzle and settings | No |
| Anonymous usage analytics (e.g. levels started/completed, feature usage) via TelemetryDeck | To improve the game | No — TelemetryDeck receives only anonymized, hashed identifiers |
Your game progress, stars, badges, streaks and settings are stored only on your device (and, if a future version adds it, in your own iCloud account). We do not have access to them.
We do not collect your name, email address, contacts, photos, location or any account information. Our servers do not store your IP address (it is used only in memory to prevent abuse).
2. Advertising
The free version shows ads provided by AppLovin (MAX) and Google AdMob and their partner networks. These providers may collect device information and, only if you allow tracking in the iOS App Tracking Transparency prompt, your device's advertising identifier (IDFA), to show and measure ads. You can change this at any time in iOS Settings → Privacy & Security → Tracking. Users in regions that require consent (such as the EEA/UK) are asked for consent before personalized ads are shown; you can review your choice in the App under Settings → Ad privacy choices.

- Google Privacy Policy: https://policies.google.com/privacy
Purchasing Remove Ads turns off banner and interstitial ads. Rewarded videos remain optional.
3. In-app purchases
Purchases are processed by Apple. We never receive your payment information.
4. Notifications
If you turn on daily reminders, notifications are scheduled locally on your device. We do not use push notification servers.
5. Data retention and deletion
Anonymous daily results are kept for up to 24 months to show historical statistics, then deleted. Badge unlock records are kept while you play and deleted after 24 months of inactivity. Because this data is not linked to you, we cannot identify which results are yours; deleting the App removes the anonymous ID from your device. If you have questions, contact us at yinqiaoyin@gmail.com.
6. Children
The App is rated for general audiences and is not directed to children under 13. We do not knowingly collect personal information from children.
7. Changes
We may update this policy. The latest version will always be available at this page, with the effective date above.

隐私政策
生效日期： 2026-10-15
Crown Logic（以下简称“本应用”）由 yinqiaoyin（以下简称“我们”）开发。本政策说明本应用使用哪些数据以及用途。本应用无需注册账号，并尽可能少地收集数据。
1. 我们收集的数据
| 数据 | 用途 | 是否与你的身份关联 |
|---|---|---|
| 本应用生成的随机匿名设备 ID | 接收每日挑战成绩并显示排名 | 否，不与你的姓名、邮箱、Apple ID 或广告标识符关联 |
| 每日挑战成绩（用时、提示次数、冲突次数、撤销次数、完成时间及时区偏移） | 计算应用内显示的每日百分位和用时分布 | 否 |
| 徽章解锁记录（徽章 ID、等级、时间） | 用于显示各徽章的获得率 | 否 |
| App 打开记录（仅日期） | 用于统计每日活跃玩家 | 否 |
| 你主动提交的反馈（内容、可选邮箱、App 与设备信息） | 用于回复和修复问题 | 不用于跟踪 |
| 基础技术信息（应用版本、平台、语言、时区） | 下发正确的每日题目和配置 | 否 |
| 通过 TelemetryDeck 收集的匿名使用统计（如关卡开始/完成、功能使用情况） | 改进游戏 | 否，TelemetryDeck 只接收匿名化、哈希处理后的标识 |
你的游戏进度、星级、徽章、连胜和设置只保存在你的设备上（未来版本如支持，也会保存在你自己的 iCloud 中），我们无法访问。
我们不收集你的姓名、邮箱、通讯录、照片、位置或任何账号信息。我们的服务器不保存你的 IP 地址（仅在内存中用于防止滥用）。
2. 广告
免费版展示由 AppLovin（MAX）、Google AdMob 及其合作广告网络提供的广告。这些服务商可能收集设备信息；仅在你于 iOS“允许跟踪”弹窗中同意后，才会收集设备广告标识符（IDFA），用于展示和衡量广告效果。你可以随时在“设置 → 隐私与安全性 → 跟踪”中更改。在需要征得同意的地区（如欧洲经济区、英国），展示个性化广告前会先征求你的同意；你可以在本应用的 设置 → Ad privacy choices 中查看或修改你的选择。
购买 去广告（Remove Ads） 后将关闭横幅和插屏广告，激励视频仍由你自愿观看。
3. 应用内购买
购买由 Apple 处理，我们不会获得你的支付信息。
4. 通知
开启每日提醒后，通知在你的设备本地安排，我们不使用推送服务器。
5. 数据保留与删除
匿名的每日成绩最长保留 24 个月，用于显示历史统计，之后删除。徽章解锁记录在你持续游玩期间保留，连续 24 个月无活动后删除。由于这些数据不与你的身份关联，我们无法识别哪些成绩属于你；删除本应用即会从设备上移除匿名 ID。如有疑问，请联系 yinqiaoyin@gmail.com。
6. 儿童
本应用面向一般用户，并非专为 13 岁以下儿童设计，我们不会故意收集儿童的个人信息。
7. 政策更新
我们可能更新本政策，最新版本将始终发布在本页面，并注明生效日期。
