Privacy Policy
How StreamTranslate collects, uses, and protects your information.
1. Information We Collect
We collect the minimum data needed to operate the service:
- Email address — collected during account creation to identify your account and send essential service communications.
- Browser fingerprint — a non-identifying hash used solely for tracking free trial usage limits. This is not linked to your personal identity.
- Twitch Channel ID — if you use the StreamTranslate Twitch Extension, your Twitch channel ID is collected to link your Twitch channel to your StreamTranslate account. No other Twitch user data (display name, email, etc.) is accessed from Twitch.
2. Payment Processing
All payments are processed securely by Stripe. We never receive, store, or have access to your full credit card number, CVV, or billing details. Stripe handles all payment data in accordance with PCI-DSS standards.
3. Audio Processing
During active streaming sessions, your microphone audio is sent in real time to Deepgram for speech-to-text transcription. Audio data is processed in-flight and is not stored by StreamTranslate or retained after the streaming session ends.
4. Translation
Transcribed text is sent to the Google Translate API to generate real-time translations. The text is processed on-demand and is not stored by StreamTranslate after the translation is delivered to your stream overlay.
5. Analytics
We use Google Analytics to understand how visitors interact with our website. This may collect anonymized usage data such as pages visited, session duration, and general geographic region. You can opt out of Google Analytics by using a browser extension or adjusting your browser settings.
6. Cookies & Local Storage
StreamTranslate does not use third-party cookies. We store session tokens in your browser's localStorage to keep you signed in. No advertising cookies or third-party tracking cookies are placed on your device.
7. Data Retention
Your account data (email address and usage records) is retained for as long as your account remains active. If you delete your account, your data will be removed from our systems. Transient data such as audio and translated text is never persisted beyond the active streaming session.
8. Third-Party Services
StreamTranslate integrates the following third-party services to operate. Each has its own privacy policy:
- Deepgram — speech-to-text transcription. Privacy Policy
- Google Translate API — text translation. Privacy Policy
- Stripe — payment processing. Privacy Policy
- Google Analytics — website analytics. Privacy Policy
- Railway — cloud hosting infrastructure. Privacy Policy
- Twitch — live streaming platform and extension host. Privacy Policy
We do not sell, rent, or trade your personal information to any third parties for marketing purposes.
9. Twitch Extension
StreamTranslate offers a Twitch Extension that displays real-time translated subtitles on live streams. When using the extension:
- Broadcaster data: We collect only the Twitch channel ID (a numeric identifier) to link the extension to a StreamTranslate account. No Twitch display names, emails, or profile data are collected from Twitch.
- Viewer data: Viewers who use the extension's language picker have their language preference stored locally in their browser (localStorage). No viewer data is sent to or stored on StreamTranslate servers. We do not collect viewer identities, Twitch usernames, or any personally identifiable information from viewers.
- Per-viewer translation: When a viewer selects a language different from the streamer's target language, the original transcript text is sent to our translation API. No viewer identity is attached to these requests.
- Extension settings: Viewer display preferences (font size, text color, box style) are stored locally in the viewer's browser and are never transmitted to our servers.
10. Your Rights (GDPR & CCPA)
Depending on your location, you may have the following rights regarding your personal data:

If you believe a child under 13 has provided us with their data, please contact us immediately.
12. Data Security
We implement industry-standard security measures to protect your data, including HTTPS encryption for all data in transit, secure database storage, and access controls. No method of transmission over the internet is 100% secure, but we take all reasonable steps to protect your personal information.
