Privacy Policy — Translator for Twitch

Extension: Translator for Twitch · Publisher: Mendo Network · Last updated: 2026-10-06

Translator for Twitch is a browser extension that translates your own Twitch chat messages from Spanish into the language configured for each streamer, before they are sent. This policy describes exactly what data the extension handles. It is written to match what the code actually does.

What is stored, and where

Everything the extension stores lives locally on your device, in chrome.storage.local:

• Your AI provider API key(s) — one per provider you configure. They never leave your device except to authenticate requests to the AI provider you choose (see below).
• The AI provider and model you selected.
• The language configured for each channel — a map of channel login → language code.
• Your glossary (global and per-channel): the terms or notes you type to steer the translation.
• A small local diagnostic log (recent events plus the last error), shown in the popup's Registro section, so you can diagnose problems without a console.

This data stays in your browser. It is not synced and it is not transmitted to the developer or to any third party.

What is sent, and to whom

• Message content: when you press Enter to send a chat message, the Spanish text you typed is sent only to the AI provider you have selected, solely to obtain the translation. It is sent together with the translation instructions and, if you have set one, your glossary/notes (the glossary is part of the prompt). Supported providers are DeepSeek (api.deepseek.com), OpenAI (api.openai.com), Anthropic/Claude (api.anthropic.com), Google Gemini (generativelanguage.googleapis.com), xAI/Grok (api.x.ai), Mistral (api.mistral.ai) and OpenRouter (openrouter.ai). No other provider receives your text. The translated text is then placed in the chat input and sent to Twitch as a normal chat message, just as if you had typed it.
• Test connection: when you press Probar conexión, your API key is sent only to the selected provider's models endpoint to verify it. No message content, glossary or other data is included.
• Channel login: only in Auto mode, one request is made to https://gql.twitch.tv (Twitch's public GraphQL endpoint) to read the stream's language. This request contains only the public channel login.

Each provider processes the text under its own terms and privacy policy; only the provider you choose receives it.

The extension does not read, translate, process or modify messages from other users, and it does not observe the incoming chat.

What is NOT collected

• No analytics, no telemetry, no tracking, no advertising identifiers.
• No personal data is collected, stored on a server, or sold.
• No browsing history is collected. The extension only runs on https://www.twitch.tv/*.

Trademarks and non-affiliation

Translator for Twitch is an independent product: it is not affiliated with, endorsed by, or sponsored by Twitch Interactive, Inc. “Twitch” is a trademark of Twitch Interactive, Inc., used here only to describe compatibility with the Twitch service.

Remote code

The extension contains no remote code. It does not load or execute scripts from a CDN or any external source, and it uses no eval().

Data deletion

You can remove all locally stored data at any time by clearing the API key(s) and channels in the extension popup, or by uninstalling the extension.
