1. Introduction

Sayborne ("the App"), operated by DEVBLOOM PTE. LTD. ("we"), values your privacy. This Privacy Policy explains how we collect, use, store, and protect your personal information. By using the App, you acknowledge that you have read and understood this Policy. If you do not agree with this Policy, please do not use the App.

2. Information We Collect

Depending on the features you use, we may collect:

• Account information: email address, sign-in method identifiers (such as Google account association), and profile details you provide.
• Voice data: audio you record when using dictation, used for real-time transcription.
• Device and usage information: device model, OS version, app version, interface language, feature usage frequency, error logs, and performance diagnostics.
• Subscription information: your Pro subscription status purchased through the App Store or Google Play (payments are processed by Apple or Google; we do not directly store your card details).
• Local history: if you enable dictation history, transcribed text is stored locally on your device.

We do not request additional sensitive personal information beyond what is necessary to provide the service.

3. Handling of Voice Data

When you use voice dictation, audio is transmitted encrypted to our cloud servers for real-time transcription. Once transcription is complete, results are returned to your device and the audio is deleted.

Concretely: audio awaiting transcription is held on a verified encrypted volume that is never backed up and never snapshotted. It is deleted as soon as the request reaches a terminal state, and an absolute fifteen-minute limit applies regardless — audio that has not already been removed is cleared when that limit is reached. Nothing about routine dictation is kept beyond that window.

The same applies to the text: neither the transcript nor the polished or translated result is retained on our servers once the request reaches a terminal state. What our database keeps is a reference to the request and the usage metadata needed for quota and billing — not the content of what you said or wrote. This commitment covers our own servers; the third-party providers listed in section 6 operate under their own policies.

If you voluntarily submit feedback, we may collect related diagnostic information to the extent needed to resolve the issue; only with your explicit consent will we use anonymized samples to improve service quality.

4. How We Use Information

We use collected information to:

• provide, maintain, and improve voice transcription, the keyboard extension, and account features;
• verify identity, manage sessions, and handle subscription status;
• sync daily usage quota and display it in the keyboard;
• troubleshoot, secure the service, and prevent abuse;
• with your consent, send important service-related notifications.

We do not sell your personal information, nor use it for advertising targeting unrelated to the App.

5. Keyboard Extension and Local Sharing

Sayborne includes a system keyboard extension. The main app and the keyboard share necessary data locally on your device (such as login state, dictation language, text to insert, and usage quota) to complete voice input in third-party apps.

This shared data is stored on your device and is not uploaded merely because the keyboard is enabled — we do not upload all of your input in other apps. The keyboard requires network access to provide real-time transcription; we transmit only the data necessary to provide the service.

6. Third-Party Services

The App may use the following third-party services:

• Google — Google Sign-In, Google Play subscriptions, and system frameworks;
• Apple — Sign in with Apple and App Store subscriptions;
• Alibaba Cloud (DashScope) — speech transcription and spoken-language identification. This provider receives your dictated audio.
• DeepInfra — speech transcription and spoken-language identification. This provider receives your dictated audio.
• DeepSeek — text translation, scene classification and text polishing. This provider receives the transcribed text, not the audio.
• xAI — scene classification and text polishing. This provider receives the transcribed text, not the audio.

Your dictation is processed by our own models on our own servers first. The four speech and text providers above are used only when our own models cannot serve the request — because they are at capacity or temporarily unavailable, or because you asked for a language they do not support. They are named individually because your audio or text does reach them.

These third parties have their own privacy policies. We require providers to process data only as needed to perform the contract and to comply with applicable data protection obligations. The App may contain links to third-party websites; we are not responsible for their content or privacy practices.

7. Data Retention

• Voice dictation data: deleted once the request reaches a terminal state, with a hard fifteen-minute upper limit; held meanwhile on an encrypted volume that is never backed up or snapshotted.
• Account information: retained while your account is active. Deleting your account removes it immediately — your email address, profile, saved phrases, sign-in credentials, device links and dictation statistics are erased in one step. Billing and credit records that we must keep for legal and accounting reasons are retained, detached from your identity so they can no longer be traced back to you.
• Dictation history: stored locally on your device by default; retention duration is set by you in the app's "Keep history" setting. You may delete individual or all history entries at any time.
• Diagnostics and logs: generally retained no more than ninety (90) days for security auditing and troubleshooting.

8. Information Security

We take reasonable technical and organizational measures to protect your information, including encryption in transit, access controls, and security auditing. Although we strive to protect your information, transmission over the internet and electronic storage cannot be guaranteed absolutely secure. If a security incident occurs that may affect your rights, we will notify you and take remedial measures as required by law.

9. Your Rights

Subject to applicable law, you may have the right to access, correct, and delete your personal information; restrict or object to certain processing; withdraw consent; and obtain a copy of your data. You can delete your account yourself in the app under Account settings, or — if you no longer have the app installed — from our account deletion page using a code sent to your email address; deletion takes effect immediately. For the other rights, email [email protected]. We will respond to your request within a reasonable period. If you are located in the EU, UK, or another region with a data protection authority, you have the right to lodge a complaint with your local regulator.

10. Children's Privacy

The App is not directed to children under 13 (under 16 outside the United States). We do not knowingly collect personal information from children in this age group. If you believe we have inadvertently collected a child's information, please contact us and we will delete it promptly.

11. Cross-Border Transfers

Your information may be processed or stored outside your country or region. We take appropriate measures to ensure cross-border transfers comply with applicable law and provide a level of protection consistent with this Policy.

12. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will revise the "Last updated" date at the top and notify you in-app or by other reasonable means. If changes materially affect your rights, we will notify you in advance. Your continued use of the App after the changes take effect constitutes acceptance of the updated Policy.

13. Contact Us

If you have any questions about this Privacy Policy or the handling of your personal information, please email [email protected].

1. 引言

Sayborne（以下简称「本应用」）由 DEVBLOOM PTE. LTD.（以下简称「我们」）运营，我们重视您的隐私。本隐私政策说明我们如何收集、使用、存储及保护您的个人信息。使用本应用即表示您已阅读并理解本政策。若您不同意本政策，请勿使用本应用。

2. 我们收集的信息

根据您使用的功能，我们可能收集以下信息：

• 账户信息：电子邮箱地址、登录方式标识（如 Google 账户关联信息）及您主动填写的个人资料。
• 语音数据：您在使用听写功能时录制的音频，用于实时转写。
• 设备与使用信息：设备型号、操作系统版本、应用版本、界面语言、功能使用频次、错误日志及性能诊断数据。
• 订阅信息：通过 App Store 或 Google Play 购买的 Pro 订阅状态（由 Apple 或 Google 处理支付，我们不直接存储您的银行卡信息）。
• 本地历史记录：若您开启听写历史功能，转写文本将保存在您的设备本地。

除提供服务所必需外，我们不会要求您提供额外的敏感个人信息。

3. 语音数据的处理

当您使用语音听写时，音频数据会加密传输至我们的云服务器进行实时转写。转写完成后，结果返回至您的设备，音频随即被删除。

具体而言：待转写的音频存放在经过验证的加密卷上，该卷不进入备份、也不做快照。请求进入终态后音频立即被删除；同时存在十五分钟的绝对上限——届时尚未删除的音频一律清除。日常听写不会有任何内容留存超过这个时间窗。

文本同理：转写结果以及润色、翻译后的文本，在请求进入终态后同样不在我们的服务器上留存。数据库中保留的是请求引用与额度、计费所需的用量元数据，不包含您所说或所写的内容本身。该承诺的范围是我们自己的服务器；第 6 节列出的第三方服务商适用各自的政策。

若您自愿提交问题反馈，我们可能在解决问题所需的范围内收集相关诊断信息；仅在您明确同意时，才会使用匿名化样本改进服务质量。

4. 信息的使用方式

我们使用收集的信息用于：

• 提供、维护和改进语音转写、输入法扩展及账户相关功能；
• 验证身份、管理会话及处理订阅状态；
• 同步每日使用额度并在键盘中展示；
• 排查故障、保障服务安全及防止滥用；
• 在获得您同意的前提下，发送与服务相关的重要通知。

我们不会将您的个人信息出售给第三方，也不会将其用于与本应用无关的广告定向。

5. 输入法扩展与本地共享

Sayborne 包含系统输入法扩展。主应用与输入法通过设备本地共享机制在您的设备上共享必要数据（如登录状态、听写语言、待插入文本、使用额度等），以便在第三方应用中完成语音输入。

该共享数据存储在您的设备上，不会仅因启用输入法而额外上传您在其它应用中的全部输入内容。输入法需要网络访问权限以提供实时转写服务；我们仅传输提供服务所必需的数据。

6. 第三方服务

本应用可能使用以下第三方服务：

• Google —— Google 登录、Google Play 订阅与系统框架；
• Apple —— 通过 Apple 登录与 App Store 订阅；
• 阿里云（DashScope）—— 语音转写与语种识别。该服务商会接收您听写的音频。
• DeepInfra —— 语音转写与语种识别。该服务商会接收您听写的音频。
• DeepSeek —— 文本翻译、场景识别与文本润色。该服务商接收的是转写后的文本而非音频。
• xAI —— 场景识别与文本润色。该服务商接收的是转写后的文本而非音频。

您的听写首先由我们自有服务器上的自有模型处理。上述四家语音与文本服务商仅在自有模型无法承接时才会用到——自有模型已满负荷或暂时不可用，或您选择的语言不在其能力范围内。由于您的音频或文本确实会到达这些服务商，因此逐一具名列出。

上述第三方各自有独立的隐私政策。我们要求服务提供商仅在履行合同所需范围内处理数据，并遵守相应的数据保护义务。本应用可能包含指向第三方网站的链接；我们不对第三方网站的内容或隐私做法负责。

7. 数据保留

• 语音听写数据：请求进入终态后即删除，并有十五分钟的硬性上限；其间存放于不备份、不快照的加密卷。
• 账户信息：在您的账户有效期间保留。注销账户会立即删除它——邮箱、个人资料、常用语、登录凭据、设备绑定与听写统计一并清除。因法律与会计义务必须保留的账单与额度记录会留存，但已与您的身份解除关联，无法再追溯到您本人。
• 听写历史：默认存储在您的设备本地，保留时长由您在应用内的「保留历史」设置决定。您可随时删除单条或全部历史记录。
• 诊断与日志：通常保留不超过九十（90）天，用于安全审计与故障排查。

8. 信息安全

我们采取合理的技术与管理措施保护您的信息，包括传输加密、访问控制及安全审计。尽管我们努力保障信息安全，但互联网传输与电子存储无法保证绝对安全。若发生可能影响您权益的安全事件，我们将依法及时告知并采取补救措施。

9. 您的权利

根据适用法律，您可能享有以下权利：访问、更正、删除您的个人信息；限制或反对某些处理活动；撤回同意；以及获取数据副本。您可在应用内的账户设置中自行注销账户；若已卸载应用，也可通过账户注销页面用邮箱验证码完成注销，注销立即生效。其余权利请发送邮件至 [email protected] 行使，我们将在合理期限内回复您的请求。若您位于欧盟、英国或其他设有数据保护机构的地区，您有权向当地监管机构投诉。

10. 儿童隐私

本应用不面向 13 周岁以下儿童（美国以外地区为 16 周岁以下）。我们不会故意收集该年龄段儿童的个人信息。若您发现我们无意中收集了儿童信息，请联系我们，我们将尽快删除。

11. 跨境传输

您的信息可能在您所在国家/地区以外进行处理或存储。我们会采取适当措施，确保跨境传输符合适用法律要求，并为您的信息提供与本政策一致的保护水平。

12. 政策变更

我们可能不时更新本隐私政策。更新后，我们将修改文首的「最后更新」日期，并在应用内或通过其他合理方式通知您。若变更实质上影响您的权利，我们将提前通知。变更生效后您继续使用本应用，即视为接受更新后的政策。
