概述
嘎嘎笔画-智能隐私输入法（App 显示名「嘎嘎笔画-智能隐私输入法」，键盘名「嘎嘎」，以下简称"嘎嘎"或"本应用"）由独立开发者开发，致力于保护用户隐私。本隐私政策说明我们如何收集、使用和保护你的个人信息。
核心承诺：键盘扩展零权限、零网络、零数据收集。你输入的一切只存在于你的设备上。
Overview
Gaga Stroke – Smart Private Input Method (app display name "嘎嘎笔画-智能隐私输入法 / Gaga Stroke", keyboard name "嘎嘎 / Gaga", hereinafter "Gaga" or "the app") is developed by an independent developer and is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and protect your personal information.
Our core promise: the keyboard extension requires zero permissions, zero network access, and collects zero data. Everything you type stays on your device.
我们收集什么数据
键盘扩展
✓ 不收集任何数据。
- 不请求任何权限，也不依赖"允许完全访问"，所有输入功能在默认状态下即可正常使用
- 无法连接网络（iOS 系统强制隔离）
- 不能读取通讯录、剪贴板、相册、位置
- 不追踪输入内容，所有输入直接上屏到系统文本框
- 笔画解码、词格整句、词组联想、字频学习全部在设备本地（自研引擎）完成，不上传
主应用
✓ 仅在以下场景使用网络：
- 购买与订阅：连接 Apple App Store 验证和完成支付。此过程由 Apple 处理，我们无法访问你的支付信息。
- 恢复购买：从 Apple 服务器同步已购项目。
- iCloud 用户词同步（可选）：你开启后，常打的字词通过你自己的 iCloud（Apple CloudKit）在你自己的设备间同步，数据存在你的 Apple ID 私有空间内，我们不运营任何服务器、也无法读取。
- 除此之外，主应用也不主动联网或上传任何数据。
What Data We Collect
Keyboard Extension
✓ We collect no data.
- It requests no permissions and does not rely on "Allow Full Access"; all input features work normally in the default state
- It cannot connect to the network (enforced by iOS sandbox isolation)
- It cannot read your contacts, clipboard, photo library, or location
- It does not track what you type — all input goes directly to the system text field
- Stroke decoding, lattice-based sentence input, phrase prediction, and word-frequency learning all run locally on your device (self-built engine) and are never uploaded
Main App
✓ The network is used only in these scenarios:
- Purchases & subscriptions: connecting to the Apple App Store to verify and complete payments. This is handled by Apple; we cannot access your payment information.
- Restore Purchases: syncing previously purchased items from Apple's servers.
- iCloud word sync (optional): when you enable it, the words you use most sync between your own devices through your own iCloud (Apple CloudKit). The data lives in your Apple ID's private space; we run no servers and cannot read it.
- Apart from these, the main app does not proactively connect to the network or upload any data.
数据存储
以下数据仅存储在本地设备中（通过 iOS App Group group.com.strocle.gagastroke 在键盘与主应用之间共享）：
- 订阅状态：存储在 iOS Keychain 和 App Group 共享 UserDefaults 中，用于键盘扩展校验会员权限。
- 用户词频 / 用户词库：你选字、选词的频率与个人词条记录，仅用于个性化候选排序。存储在 App Group 容器内，不上传。
- 剪贴板历史（会员）：长按空格可见的最近若干条复制内容，仅保存在本机 App Group 容器内，可用一键清空，不上传。
- 输入历史：不保存。每次键盘关闭即清除。
以上数据均不与任何第三方共享，不会离开你的设备；iCloud 词同步的数据存储在你自己的 iCloud 私有空间内。
Data Storage
The following data is stored only on your local device (shared between the keyboard and the main app through the iOS App Group group.com.strocle.gagastroke):
- Subscription status: stored in iOS Keychain and the App Group shared UserDefaults, used only by the keyboard extension to verify membership.
- User word frequency / user dictionary: records of the characters and words you choose, used only for personalized candidate ranking. Stored in the App Group container and never uploaded.
- Clipboard history (members): the recent copied items shown when you long-press the space bar, stored only in the on-device App Group container, clearable in one tap, never uploaded.
- Input history: not saved; cleared every time the keyboard is dismissed.
None of this data is shared with any third party and never leaves your device; iCloud word-sync data lives in your own iCloud private space.
第三方服务
本应用使用的第三方服务仅有 Apple 提供的能力：StoreKit（App 内购买与订阅）与 CloudKit（可选的 iCloud 用户词同步）。两者均由 Apple Inc. 提供并受 Apple 隐私政策 约束。
我们无法访问你的 Apple ID、支付方式或购买记录详情，也无法读取你 iCloud 私有空间内的同步数据。
本应用不使用任何分析 SDK、广告 SDK、统计工具或第三方追踪服务。
Third-Party Services
The only third-party services used by this app are Apple capabilities: StoreKit (in-app purchases and subscriptions) and CloudKit (optional iCloud word sync). Both are provided by Apple Inc. and governed by the Apple Privacy Policy.
We cannot access your Apple ID, payment method, or purchase details, nor can we read the synced data in your iCloud private space.
This app does not use any analytics SDK, advertising SDK, statistics tool, or third-party tracking service.
键盘扩展的隐私保护原理
iOS 键盘扩展运行在严格的系统沙箱中：
- 默认情况下，键盘不能访问网络
- 默认情况下，键盘不能访问其他 App 的数据
- 嘎嘎不请求任何权限，也强烈建议用户保持"允许完全访问"关闭。本键盘所有功能（笔画输入、词格整句、词组联想、候选排序、大字模式、多彩皮肤、上滑 / 手写输入、触感与音效）均在关闭完全访问的状态下正常工作。
与其他需要"允许完全访问"才能联网的第三方键盘不同，嘎嘎从设计上就不依赖该权限，iOS 的系统隔离从根源上杜绝了数据外泄的可能。
How the Keyboard Extension Protects Your Privacy
iOS keyboard extensions run in a strict system sandbox:
- By default, the keyboard cannot access the network
- By default, it cannot access data from other apps
- Gaga requests no permissions and we strongly recommend keeping "Allow Full Access" turned off. All keyboard features (stroke input, lattice-based sentence input, phrase prediction, candidate ranking, large-text mode, themes, swipe / handwriting input, haptics and key sounds) work normally with Full Access disabled.
Unlike other third-party keyboards that need "Allow Full Access" to connect, Gaga is designed from the ground up not to rely on that permission — iOS sandbox isolation eliminates any possibility of data leakage at its root.
剪贴板功能与"允许完全访问"
嘎嘎的剪贴板功能（长按空格查看或粘贴最近复制的内容）需要读取系统剪贴板。受 iOS 系统限制，键盘扩展只有在开启"允许完全访问"权限后才能访问剪贴板。
如果你希望使用剪贴板功能，请在系统设置中为本键盘开启"允许完全访问"：
- 打开 iOS「设置」→「通用」→「键盘」→「键盘」→ 选择「嘎嘎」
- 开启「允许完全访问」开关
开启后的隐私说明
开启"允许完全访问"后，系统的网络访问能力会被技术上开放。但嘎嘎键盘扩展仍然不联网、不上传任何数据；即便开启完全访问，所有剪贴板内容也仅保存在本机 App Group 容器内，不离开你的设备，可用一键清空。
如你不希望开启该权限，剪贴板功能将不可用，但所有其他输入功能（笔画输入、词格整句、词组联想、候选排序、多彩皮肤、上滑 / 手写输入、触感与音效等）均不受影响、照常使用。
Clipboard Feature & "Allow Full Access"
Gaga's clipboard feature (viewing or pasting recently copied items by long-pressing the space bar) needs to read the system clipboard. Due to iOS system restrictions, the keyboard extension can only access the clipboard after "Allow Full Access" is enabled.
If you wish to use the clipboard feature, please enable "Allow Full Access" for this keyboard in system settings:
- Open iOS Settings → General → Keyboard → Keyboards → select "Gaga"
- Turn on the "Allow Full Access" switch
Privacy note after enabling
After enabling "Allow Full Access", network access capability is technically opened by the system. However, Gaga's keyboard extension still does not connect to the network or upload any data; even with Full Access on, all clipboard content stays only in the on-device App Group container, never leaves your device, and can be cleared in one tap.
If you prefer not to enable this permission, the clipboard feature will be unavailable, but all other input features (stroke input, lattice-based sentence input, phrase prediction, candidate ranking, themes, swipe / handwriting input, haptics and key sounds, etc.) remain unaffected and work as usual.
用户权利
由于本应用不在服务器端收集任何数据，因此：
- 不存在需要删除的云端数据（iCloud 同步数据位于你自己的 Apple ID 私有空间，可随时在系统设置中关闭或删除）
- 不存在需要导出的个人信息
- 卸载应用即清除所有本地数据（App Group 容器数据会在卸载时被系统自动清除）
如需清空本机的学习词库（不影响系统内置词库）或剪贴板历史，可在主应用设置中一键操作。
Your Rights
Because this app collects no data on our servers:
- There is no cloud data to delete (iCloud-synced data lives in your own Apple ID private space and can be turned off or deleted in system settings at any time)
- There is no personal information to export
- Uninstalling the app clears all local data (the App Group container data is automatically cleared by the system on uninstall)
To clear the on-device learning dictionary (without affecting the built-in system dictionaries) or the clipboard history, use the one-tap options in the main app's settings.
儿童隐私
本应用不收集任何人的个人数据，包括儿童。所有年龄段的用户享有同等的隐私保护。
Children's Privacy
This app does not collect personal data from anyone, including children. Users of all ages receive the same privacy protection.
隐私政策更新
本隐私政策可能随时更新。重大变更时，我们会在应用内显著位置通知。建议你定期查阅本页面。
Changes to This Privacy Policy
This Privacy Policy may be updated at any time. For significant changes, we will notify you prominently within the app. We recommend reviewing this page periodically.
