Privacy Policy

Effective date: 2026-10-10 Contact: [email protected]

This Privacy Policy explains how DubTab (the "Service") collects, uses, and shares information when you use the DubTab browser extension, the DubTab desktop app for Windows and Mac, and related websites.

The two apps share one account, one engine and one set of practices. Where the desktop app differs — mainly because it can capture audio outside the browser — the differences are set out in Section 7.

1. Information we collect

A) Content processed to provide the Service

When you start a DubTab session — on a browser tab with the extension, or on an application, your system audio, or a video or audio file with the desktop app — the Service may process:

• Source audio in short segments to generate transcription, translation, subtitles, and/or AI voice. The source is the browser tab you enable DubTab on, or — in the desktop app — the single application or the system output you select, or the sound of a video or audio file you open
• Generated text output such as transcripts, subtitles, translations, summaries, and Ask AI content
• Optional saved dubbed audio consisting only of the translated AI voice generated by DubTab
• Saved-audio metadata needed for preparation, playback, caption highlighting, deletion, and storage management

Source audio is processed in real time and is not saved by DubTab as a recording. Neither app has a microphone source; they process what your browser or your computer plays, not what you say. Saving dubbed audio is off by default. If you turn it on, DubTab assembles and stores only the translated AI voice it successfully generates; it does not save the original source audio, your microphone, or system audio as part of the saved file.

Limited temporary buffering and short-lived processing files may be used to deliver streaming results and prepare saved dubbed audio.

B) Account and subscription information

If you sign in or purchase a plan, we may collect:

• Account identifier (such as email address and user ID)
• Subscription status and billing metadata (such as plan name and renewal status)

Payments are handled by third-party payment processors. DubTab does not store full payment card details.

C) Usage and diagnostics

To operate and improve the Service, we may collect:

• Basic usage events (e.g., start/stop, selected languages, feature settings)
• Video and audio files you open in the desktop app — the file's name and the name of the folder it is in (never its full location on your computer), an anonymous identifier for the file, and technical details such as its length, size and format
• Diagnostics (e.g., error logs, performance/latency metrics)
• App/device info — for the extension, browser type and version and the extension version; for the desktop app, the app version, your operating system and its version, and CPU architecture

2. How we use information

We use information to:

• Provide real-time transcription, translation, subtitles, and AI voice
• Store and display History content, including optional dubbed-audio playback and caption highlighting
• Maintain, secure, and improve the Service
• Provide customer support
• Manage subscriptions, usage limits, and prevent abuse
• Comply with legal obligations

We do not sell your personal information.

3. How we share information

DubTab may share information with service providers only as needed to run the Service, such as:

• Speech recognition, translation, and text-to-speech providers
• Software distribution and update hosting (for the desktop app)
• Cloud hosting, database, and private object-storage providers
• Authentication, analytics, and diagnostics providers
• Payment processors

These providers process data only to provide services for DubTab and are required to protect it.

Information may also be disclosed if required by law or to protect the security and integrity of the Service.

4. Data retention

DubTab aims to minimize data collection and retention:

• Source audio is processed transiently and is not saved by DubTab as a recording.
• History text and optional saved dubbed audio are retained only as long as reasonably necessary to provide History and related features, unless you delete them earlier. Saved dubbed audio is not intended to be a permanent archive and may be removed under the Service's storage and deletion practices.
• Temporary buffers and processing files are removed when they are no longer needed for delivery or audio preparation.
• Account and billing records may be retained as required for account operation and legal/compliance purposes.

Deletion may take a short time to complete across active systems and service providers. Limited backup, security, or legal records may remain where reasonably necessary or required by law.

5. Security

Reasonable measures are used to protect data, including access controls, encryption in transit, private object storage for saved dubbed audio, and short-lived authorized playback links. No system can be guaranteed 100% secure.

6. Your choices

You can stop real-time processing at any time by pausing or stopping the session, turning off DubTab, or closing the tab. Nothing is captured before you start a session. You can also manage extension permissions in your browser settings, and — for the desktop app — the choices described in Section 7.

Saving dubbed audio is off by default. You can turn it on or off before starting a session. Turning it off prevents future sessions from saving dubbed audio but does not delete audio already saved in History.

You can delete saved dubbed audio from History without deleting the session's subtitles. Deleting the entire session also removes its saved dubbed audio. To request access to or deletion of account-related data, contact [email protected].

7. Desktop app (Windows and Mac)

The desktop app does everything the extension does, plus one thing the extension cannot: it listens to audio that never passes through a browser. This section covers only what is different.

What it captures

You choose the source before each session:

• A single application — DubTab receives audio only from that application's process
• Your whole system — DubTab receives whatever your computer plays, whichever application produced it
• A video or audio file on your computer — DubTab plays the file in its own player and sends only the sound of the part it is preparing, at most a few minutes ahead of where you are watching. It never sends the picture, and it does not upload or copy the file. The file's name becomes the title of its session in your History

The app has no microphone source at all. It cannot access your microphone; there is no code path in the app that does. It hears what your computer plays, never what you say. DubTab also excludes its own AI voice from what it captures, so its dubbing is never fed back into transcription.

Capture runs only while a session is running. Nothing is captured before you press start, and capture stops when you pause or stop.

What whole-system capture means for you

In whole-system mode, DubTab processes everything your computer plays while the session is running — including audio you did not intend to translate, such as a notification sound or a video playing in another window. If you want only one source translated, choose the single-application mode.

If you run DubTab during a call or meeting, the audio of the other participants is processed like any other audio. Depending on where you are and what is being discussed, you may need to inform them or obtain their consent first. That is your responsibility; the app cannot determine it for you.

The macOS permission

On a Mac, macOS asks you once — the first time you start a session — to allow DubTab to record system audio. That permission is what lets the app hear what your computer plays. DubTab does not request screen recording permission, and it has no microphone access at all. You can withdraw the permission at any time in System Settings › Privacy & Security; without it, the app cannot capture audio. On Windows no such permission exists, and none is requested.

Data kept on your computer

The app stores a small amount of data in your user profile — on Windows in %APPDATA%\DubTab, on Mac in ~/Library/Application Support/DubTab:

• Your settings and preferences — languages, voices, keyboard shortcuts, window layout
• A randomly generated installation identifier used for diagnostics
• Downloaded update files, until the update has been installed
• A list of the video and audio files you have played — where each one is on your computer, how far you got, and a small preview image — so you can find and resume them. These file locations are never sent to us

Uninstalling the app does not delete these files. They are kept so that reinstalling restores your settings. To remove them, delete the DubTab folder in the location above after uninstalling — on Mac, moving the app to the Trash does not remove it. Deleting local files does not delete anything held in your account — for that, contact us.

Prepared subtitles and dubbing for video files are stored separately, so that watching a prepared part again costs nothing: on Windows in %LOCALAPPDATA%\DubTab\PreparedVideos, on Mac in ~/Library/Caches/DubTab/PreparedVideos. They use up to 2 GB; past that, the oldest are removed first. You can clear them at any time in Settings › Prepared videos. On Windows, uninstalling the app removes them; on Mac, delete that folder yourself.

Automatic updates

The app periodically asks our update server whether a newer version is available. That request carries your current app version and platform, and — as with any download — reveals your IP address to that server.

Diagnostics

In released builds, the app sends usage and diagnostic events: session start and stop, selected languages, feature settings, errors, and the app/device information described in Section 1(C). Before you sign in, these events carry the installation identifier above; once you sign in, they are associated with your account. These events do not contain your audio, your transcripts, or your translations. For video and audio files you open, they include the file's name and its folder's name, as described in Section 1(C).

8. Chrome Web Store Limited Use

This section applies to the browser extension only. DubTab's use and transfer of information received from Google APIs adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements.

9. Changes to this Privacy Policy

This Policy may be updated from time to time. The "Effective date" will be updated. Material changes will be posted on the website or within the Service.
