Video Voice Translate · Last updated: 25 October 2026

This policy explains what data Video Voice Translate ("the app", "we") collects, how we use it, and who we share it with. By using the app you agree to this policy. 本政策说明 Video Voice Translate 收集哪些数据、如何使用、与谁共享。

1. Information we collect

Account info — if you sign in with Google or TikTok: your email address and a basic profile identifier. You can also use the app anonymously (a random device identifier) without an account.
Translation content — the on-screen text, video audio, or spoken audio you choose to translate is processed to produce a translation.
Purchase & subscription data — your Google Play purchase tokens and subscription status (processed via Google Play Billing).
Usage & diagnostics — app usage events, quota consumption, device model, OS version, app version, coarse region/language, and crash reports.

2. How we use your data

To provide translation, subtitle, and voice features.
To create an AI summary of a video when you tap "AI Summary": the video's subtitle text and file name are sent to an AI provider to write the summary. 你点「AI 总结」时,把该视频的字幕文字和文件名发送给 AI 服务商生成总结。
To manage your account, subscription, and usage quota.
To show ads and measure app performance and crashes.
To improve reliability and prevent abuse.

3. Third parties we share data with

To deliver core features, some content and data are sent to trusted third-party services:

Service	Data shared	Purpose
AI translation & speech providers — Alibaba Cloud (Qwen), DeepSeek, Zhipu (GLM), Google Translate	The text and audio you submit for translation	Machine translation & speech recognition
AI summary providers — OpenAI, DeepSeek (through OpenRouter), Alibaba Cloud (Qwen)	The subtitle text and file name of the video you ask to summarize	Writing the AI summary you requested. Providers are tried in order; if one fails, the next one receives the same text. We ask providers not to store or train on this content where they offer that option.
Google Play Billing	Purchase tokens, order IDs	Process purchases & subscriptions
Google AdMob	Advertising identifiers, coarse device data	Show ads (per your consent in EEA/UK)
Google Firebase (Analytics, Crashlytics)	Usage events, crash logs, device data	Analytics & crash reporting
TikTok (only if you choose TikTok login)	Login authorization	Account sign-in

We do not sell your personal data. Translation and summary content is sent to the providers above only to produce the result you requested. 我们不出售你的个人数据;翻译和总结内容仅为生成你请求的结果而发送给上述服务商。

4. Data retention & deletion

Your account data is kept while your account is active. You can delete your account and associated data at any time — see our Account Deletion page. Records required for financial/legal compliance (e.g. purchase receipts) are retained only in de-identified form. 你可随时删除账号及数据,见删除页;合规所需记录仅以去标识化形式保留。

AI summaries are stored on our servers so you can open them again. Deleting a summary, deleting the video task, or deleting your account removes it. AI 总结保存在我们的服务器上,方便你再次查看;删除这份总结、删除该视频任务或注销账号时会一并删除。

5. Children

The app is not directed to children under 13, and we do not knowingly collect their data.

6. Consent (EEA / UK)

In the EEA and UK, personalized ads are shown only after you provide consent via the Google-certified consent prompt. You can withdraw consent anytime in the app's settings.

7. Changes

We may update this policy; the "Last updated" date above will reflect changes.
