Privacy Policy / 隐私政策
English1. Who we are
Natively (“we”, “us”, “the app”) is an iOS custom keyboard application that helps non-native English speakers write more naturally. Natively is built and operated by Devy Han, an independent developer based in Irvine, California, USA.
If you have any questions about this policy, contact us at legal@trynatively.app.
2. What this policy covers
This policy explains what information Natively collects, how it’s used, and what your rights are. Because Natively is a keyboard, we want to be especially clear about what we can and cannot see when you type.
3. What we collect
Text you type while using Natively as your active keyboard. When you tap the “rewrite” button, the text you’ve entered is sent to our servers to be rewritten by an AI model.
We do not collect:
- Anything you type in password fields. Natively detects secure text fields (password inputs) and completely disables AI processing in those contexts. No data leaves your device.
- Anything you type while another keyboard (e.g. the system keyboard) is active.
- Your contacts, photos, location, microphone, camera, or any other personal information.
- Your name, email address, or other identifying information — unless you voluntarily provide them (e.g. by joining our waitlist or contacting support).
4. How we process your text
When you trigger an AI rewrite, the following happens:
- The text is sent over an encrypted HTTPS connection to our backend proxy, hosted on Cloudflare Workers.
- Our proxy forwards the text to OpenAI’s API (specifically the
gpt-4o-minimodel) for rewriting. - The rewritten result is returned to your device.
- The text is not stored on our servers, OpenAI’s servers (under their API data usage policy), or anywhere else. It exists only in transit.
- The text is not used to train AI models, ours or anyone else’s.
5. What we store
On your device:
- A randomly generated user ID (UUID) stored in iOS Keychain. This ID is used solely for rate limiting (to prevent abuse) and is not linked to your real identity.
- Your app preferences (writing style, language mode, etc.).
On our servers (Cloudflare KV):
- Your random user ID and a daily request count. This expires automatically after 48 hours.
That’s it.
6. Third-party services
Natively uses the following third parties to operate:
- OpenAI (api.openai.com) — for AI text rewriting. Your text is processed under OpenAI’s API data usage policies, which state that API inputs are not used to train OpenAI models.
- Cloudflare (cloudflare.com) — hosts our backend proxy and stores rate limit counters. Cloudflare may log standard request metadata (IP address, request timestamp) per their privacy policy.
- Apple — provides the iOS platform, App Store, and TestFlight. Apple’s data practices are governed by Apple’s privacy policy.
We do not share your data with any other third parties. We do not sell your data, ever.
7. Children’s privacy
Natively is not directed to children under 13. We do not knowingly collect personal information from children. If you believe a child has used Natively, please contact us and we will take appropriate action.
8. Your rights
You have the right to:
- Stop using Natively at any time. Simply uninstall the app or disable the keyboard in iOS Settings → General → Keyboards.
- Request deletion of your user ID and any associated rate limit data by emailing legal@trynatively.app. Since we don’t store identifying information, deletion takes effect immediately and is irreversible.
- Ask questions about how your data is handled at legal@trynatively.app.
9. Data location
Our servers (Cloudflare Workers) are distributed globally and your requests are processed at the data center geographically closest to you. OpenAI’s servers are located in the United States.
10. Security
All data in transit is encrypted using HTTPS / TLS 1.3. Our backend uses authenticated request tokens to prevent unauthorized access. We do not store any sensitive information that would be valuable to an attacker.
11. Changes to this policy
We may update this policy from time to time. When we do, we’ll update the “Last updated” date at the top. For significant changes, we’ll notify users via the app or email (if you’ve joined our waitlist).
12. Contact
If you have questions, concerns, or requests related to this policy, please email us at legal@trynatively.app. We read every message.

1. 我们是谁
Natively（“我们”、“本应用”）是一款 iOS 自定义键盘应用，帮助非英语母语者更自然地表达英文。Natively 由独立开发者 Devy Han 开发和运营，位于美国加州尔湾。
如对本政策有任何疑问，请联系我们：legal@trynatively.app
2. 本政策的范围
本政策解释了 Natively 收集哪些信息、如何使用，以及你的权利。由于 Natively 是一个键盘，我们希望特别清楚地说明：你输入文字时，我们能看到什么、不能看到什么。
3. 我们收集的内容
你在使用 Natively 作为当前键盘时输入的文字。当你点击“改写”按钮时，你输入的文字会被发送到我们的服务器，由 AI 模型改写。
我们不会收集以下内容：
- 你在密码框中输入的任何内容。Natively 会检测密码输入框（secure text field），并在这些场景下完全禁用 AI 处理。任何数据都不会离开你的设备。
- 你在使用其他键盘（如系统键盘）时输入的内容。
- 你的通讯录、照片、位置、麦克风、摄像头或任何其他个人信息。
- 你的姓名、邮箱地址或其他身份识别信息 —— 除非你主动提供（如加入候补名单或联系支持）。
4. 我们如何处理你的文字
当你触发 AI 改写时，发生以下流程：
- 文字通过加密 HTTPS 连接发送到我们的后端代理（部署在 Cloudflare Workers 上）。
- 代理将文字转发给 OpenAI API（具体使用
gpt-4o-mini模型）进行改写。 - 改写结果返回到你的设备。
- 文字不会被存储在我们的服务器、OpenAI 的服务器（根据其 API 数据使用政策），或任何其他地方。它只存在于传输过程中。
- 文字不会被用于训练 AI 模型，无论是我们的还是任何其他公司的。
5. 我们存储的内容
在你的设备上：
- 一个随机生成的用户 ID（UUID），存储在 iOS Keychain 中。此 ID 仅用于使用频率限制（防止滥用），与你的真实身份无关联。
- 你的应用偏好设置（写作风格、语言模式等）。
在我们的服务器上（Cloudflare KV）：
- 你的随机用户 ID 和每日请求计数。此数据 48 小时后自动过期清除。
仅此而已。
6. 第三方服务
Natively 使用以下第三方服务运行：
- OpenAI（api.openai.com）—— 用于 AI 文字改写。你的文字根据 OpenAI 的 API 数据使用政策处理，该政策声明 API 输入不会用于训练 OpenAI 模型。
- Cloudflare（cloudflare.com）—— 托管我们的后端代理并存储频率限制计数。Cloudflare 可能会根据其隐私政策记录标准请求元数据（IP 地址、请求时间戳）。
- Apple —— 提供 iOS 平台、App Store 和 TestFlight 服务。Apple 的数据处理由 Apple 隐私政策管理。
我们不会与任何其他第三方共享你的数据。我们永远不会出售你的数据。
7. 儿童隐私
Natively 不针对 13 岁以下儿童。我们不会有意收集儿童的个人信息。如果你认为有儿童使用了 Natively，请联系我们，我们将采取适当措施。
8. 你的权利
你有权：
- 随时停止使用 Natively。直接卸载应用，或在 iOS 设置 → 通用 → 键盘 中禁用本键盘即可。
- 请求删除你的用户 ID 和任何关联的频率限制数据，发邮件至 legal@trynatively.app。由于我们不存储身份信息，删除立即生效且不可逆。
- 询问有关数据处理的任何问题，邮件至 legal@trynatively.app。
9. 数据位置
我们的服务器（Cloudflare Workers）分布在全球各地，你的请求会由地理上最近的数据中心处理。OpenAI 的服务器位于美国。
10. 安全性
所有传输中的数据均使用 HTTPS / TLS 1.3 加密。我们的后端使用已认证的请求令牌防止未授权访问。我们不存储任何对攻击者有价值的敏感信息。
11. 政策变更
我们可能会不时更新本政策。更新时，我们会修改顶部的“最后更新”日期。对于重大变更，我们会通过应用内提示或邮件（如果你加入了候补名单）通知用户。
12. 联系我们
如对本政策有任何问题、顾虑或请求，请发邮件至 legal@trynatively.app。我们会阅读每一条消息。
