Privacy Policy

Overview

EarDub ("we", "us") is a Chrome extension that translates YouTube videos into AI voice dubbing in your language. This policy explains what data the extension and our backend handle. EarDub is designed to work without an account and to collect as little data as possible.

What we collect

Anonymous client ID: a randomly generated identifier stored in your browser. It is used only to count your daily free quota and is not linked to your name, email, or Google account.

Caption text of videos you dub: when you click the dub button, the video's caption text and basic metadata (video ID, title, language) are sent to our servers so we can translate it and generate audio. We never see videos you merely watch without dubbing.

Settings: your language, voice, and volume preferences are stored in Chrome's extension storage and synced by Chrome if you enabled browser sync.

Feedback: if you submit feedback on our website, we receive your message and the email address you optionally provide.

We do not collect your browsing history, search queries, passwords, or payment information (EarDub currently has no payment features).

How we use data

To provide the dubbing service (translate captions and synthesize speech), to enforce the daily free quota, to debug problems and prevent abuse, and to improve translation and audio quality. We do not sell your data, show ads, or track you across websites.

Third-party processors

To run the service we send the minimum necessary data to: DeepSeek (caption text, for translation), Microsoft Azure (translated text, for speech synthesis), Cloudflare (generated audio files, for storage and delivery), Supabase (dubbing job records and usage counts, database hosting), and Vercel (API hosting). Each provider receives only what is required for its function.

Data retention and deletion

Generated audio and dubbing job records are cached so repeat requests for the same video are instant, and may be periodically cleaned up. To request deletion of data associated with your anonymous ID, email us at support@eardub.com.

Chrome permissions explained

storage: saves your settings. youtube.com access: reads caption data and overlays the dubbing player on the page. api.eardub.com access: sends captions to and receives audio from our backend. The extension runs only on youtube.com.

Children

EarDub is not directed at children under 13, and we do not knowingly collect personal information from them.

We will post any changes on this page and update the date above. Significant changes will be highlighted on our website.
