SyncTalk 隐私政策

更新日期：2026 年 11 月 3 日

SyncTalk（部分版本曾名为 Parley）提供实时语音翻译。免 Key 服务、内购和下述云端账户功能仅适用于已启用这些功能的版本。本应用不包含广告、分析或追踪 SDK。

语音、字幕和服务路径

自备 API Key 模式直接通过加密连接向所选翻译服务发送语音。免 Key 模式经 SyncTalk 的 Cloudflare 后端转发到阿里云百炼，后端验证账户、订阅和剩余额度。后端只在内存中转发音频、原文和译文，不将这些内容写入数据库、文件或应用日志。

免 Key 服务依据当前 App Store 商店地区选择翻译服务：中国大陆、香港和澳门使用北京服务，其余地区或地区未知时使用新加坡服务。此选择针对翻译提供商，不保证 Cloudflare 的处理和网络路径全部位于该地区。服务商按其自身政策处理收到的内容；我们不将后端不存储内容等同于所有服务商均不保留任何数据。

本应用不保存录音。字幕默认只在运行内存中保留。你可以主动保存字幕快照到本机，并查看、分享或删除。快照排除在设备备份之外；分享的副本由你选择的接收应用处理。删除云端账户不会删除本机快照，请在字幕记录中单独管理。

声音复刻为可选功能，自备 Key 和免 Key 模式均可使用。开启后，服务商根据当前说话人的语音生成相应音色的译文；请先取得说话人的同意。此流程不创建可复用的持久音色档案，SyncTalk 后端不保存复刻音色或相关音频。服务商处理仍适用上述政策。

云端账户、购买与额度

启用免 Key 服务时，使用 Apple 为本 App 提供的账户范围标识和签名交易信息进行验证，不读取 Apple 账号邮箱、密码或身份证号码。服务端保存必要的 App 范围账户标识、设备认证公钥和计数器、试用使用量及订阅周期使用量；不保存 Apple 签名原文、设备验证 UUID 或会话令牌。短期认证挑战在到期后自动删除。

订阅交易由 Apple 处理。服务端向 Apple 查询有效状态，以执行恢复购买、退款或撤销后的访问限制。每个账户只有一次 5 分钟试用；月付额度按实际订阅周期核算。额度按云端翻译连接占用时长扣除，包含连接后的静音时间；不按文字数量计费。意外断线的计费差额最多为 5 秒。

删除与保留

在“设置 → 翻译方案与购买 → 删除云端账户”发起删除。删除完成后，云端账户原始标识和所有设备认证公钥会被移除，旧令牌立即失效，活动连接在其最迟 5 秒的额度租约内停止。删除无法撤销；再次使用需重新验证。

为执行每账号一次试用及防止已付周期额度被重复领取，保留通过服务端秘密生成的单向账户标记和试用已使用标记；这些记录不含语音或译文。删除后未用完的试用失效。付费周期标识、周期和已用额度最迟在该周期结束 30 天后的自动清理中删除。未删除账户的身份和设备认证保留至用户发起删除。Cloudflare 的平台备份可能按其保留机制延后过期，备份不作为在线账户使用。

删除账户不会取消 Apple 自动续订，也不会申请退款。请先在 Apple 订阅设置中管理订阅。仍可选择立即删除账户。已购买的自备 Key 永久权益仍由 Apple 保存，可通过恢复购买重新取得。

API Key 与本地设置

自备 API Key 和 Workspace ID 保存在本机钥匙串，仅用于连接所选服务，不上传到 SyncTalk 后端。钥匙串项目可能随加密系统备份迁移。语言、音色及设备偏好保存在本机。设备认证标识按 App 账户隔离保存，不包含私钥或会话令牌。

服务提供方与联系

服务提供方包括 Cloudflare、Apple、阿里云；自备 Key 时也可选择千问 AI 平台。本应用不面向 13 岁以下儿童。请在录制其他人的语音前取得同意。

SyncTalk Privacy Policy

Last updated: November 3, 2026

SyncTalk (formerly Parley in some versions) provides live speech translation. Managed service, purchases, and cloud-account features described here apply only to versions where they are enabled. The app has no advertising, analytics, or tracking SDKs.

Speech, captions, and processing

Bring-your-own-key mode sends speech directly over an encrypted connection to your selected provider. Managed mode relays speech through SyncTalk's Cloudflare backend to Alibaba Cloud Model Studio. The backend verifies the account, subscription, and allowance. Audio, source text, and translations are relayed in memory and are not written to databases, files, or application logs.

The current App Store storefront chooses the managed translation provider: mainland China, Hong Kong, and Macao use Beijing; other or unavailable storefronts use Singapore. This does not guarantee that Cloudflare processing or network transit stays in that region. Providers process content under their own policies; our backend's content-storage controls do not establish that every provider retains no data.

The app does not save recordings. Captions stay in memory by default. You may save a snapshot locally, view it, share it, or delete it. Snapshots are excluded from device backups. Shared copies are handled by the recipient app. Deleting a cloud account does not remove local snapshots; manage those in caption history.

Voice cloning is optional in both BYOK and managed modes. When enabled, the provider uses the current speaker's speech to produce translations in that voice; obtain the speaker's consent first. This flow does not create reusable, persistent voice profiles. The SyncTalk backend does not store cloned voices or related audio. Provider processing remains subject to the policies above.

Cloud account, purchases, and allowance

Managed service verifies Apple's app-scoped account identifier and signed transaction data. It does not read your Apple Account email, password, or government ID. The server stores only the necessary app-scoped identifier, device public keys and counters, trial usage, and subscription-period usage. It does not persist signed Apple payloads, device-verification UUIDs, or session tokens. Short-lived authentication challenges are deleted after expiration.

Apple processes purchases. The backend queries Apple for subscription status, including restoration, refund, and revocation. Each account has one lifetime five-minute trial. Monthly allowance follows the actual subscription period. Time is deducted while the managed translation connection is open, including silence, rather than by text length. Unexpected disconnection may add at most five seconds to metered use.

Deletion and retention

Use Settings → Translation Plans & Purchases → Delete Cloud Account. Deletion removes the raw cloud identity and every registered device public key. Old tokens become invalid immediately and active connections stop within their lease of at most five seconds. Deletion is irreversible; using managed service again requires new verification.

To enforce one trial per account and prevent duplicate paid allowances, we retain a one-way account marker derived with a server secret and a spent-trial marker. These contain no speech or captions. Unused trial time expires on deletion. Paid transaction-period identifiers and usage are automatically removed 30 days after their period ends. An undeleted account's identity and device registrations remain until deletion. Cloudflare platform backups may expire later under platform retention; they are not used as live accounts.

Deletion does not cancel an Apple subscription or request a refund. Manage your subscription with Apple first; immediate deletion is still available. Apple retains your permanent BYOK purchase, which can be restored.

Your API key and local settings

Your API key and Workspace ID stay in your device's Keychain and are used only with your chosen provider, never sent to the SyncTalk backend. Keychain items may migrate with encrypted system backups. Language, voice, and device preferences stay locally. Device registration IDs are isolated by app account and contain no private keys or session tokens.

Providers and contact

Providers include Cloudflare, Apple, and Alibaba Cloud; BYOK also supports Qianwen AI Platform. The app is not directed to children under 13. Obtain permission before capturing someone else's speech.
