Privacy Policy

Scope

This Privacy Policy applies to the Transmux desktop application, the Transmux website, release downloads, and related support channels operated by Piyush Doorwar (the "Developer"). By using Transmux or the Transmux website, you agree to this policy.

Plain-English Summary

Transmux converts local media files on your device. The Developer does not collect your media files, conversion history, subtitle files, settings, or activity from the app.

Data the App Stores Locally

Transmux stores limited data on your device to preserve your preferences between sessions:

• Your last selected output format.

On supported desktop systems this data is stored in the operating system's application data area, including a Transmux settings.json file. It remains on your device unless you share it, back it up, sync it, or delete it through your system.

Media Files and Local Conversion

Transmux opens input files you choose through the file picker or drag and drop, and writes output files to a path you specify. Conversion is entirely local. The app does not upload your audio, video, subtitle files, or converted output to the Developer.

If you use operating-system integrations, installers, file associations, sandbox permissions, or Flatpak portals, your operating system may process file paths and permissions according to its own behavior.

Update Checks

The About dialog includes a manual "Check for Updates" action. When you use it, Transmux contacts the GitHub releases API to check the latest published version. GitHub may receive your IP address, user agent, request time, and other standard request metadata.

The update check is not routed through a Developer-controlled server. Transmux does not send your media files, settings, or personal files as part of the update check.

Website and Release Downloads

The Transmux website fetches public release information from GitHub so it can show download links. When you visit the website, download releases, open GitHub links, or report issues on GitHub, GitHub and your browser/network providers may receive standard web request data.

The Transmux website currently uses Cloudflare Web Analytics. Cloudflare may process limited website analytics data such as page views, referrers, device/browser information, approximate location derived from IP address, and similar request metadata. The Developer does not use the Transmux desktop app to send analytics events.

Support, Email, and Issues

If you email support, open a GitHub issue, submit a pull request, or otherwise contact the Developer, you choose what information to provide. That may include your name, email address, GitHub username, operating system, logs, screenshots, media filenames, file paths, or other diagnostic details.

Please avoid sending private media files, sensitive screenshots, secrets, passwords, API keys, or personal information that is not needed to handle your request.

What the Developer Does Not Do

• The Developer does not sell your personal data.
• The Developer does not operate Transmux user accounts.
• The Developer does not collect your media files from the app.
• The Developer does not track your conversions or file activity from the app.
• The Developer does not receive your local media files, subtitle files, or conversion output from the app.
• The Developer does not use the desktop app for advertising, profiling, or hidden telemetry.

Third-Party Software and Services

Transmux uses third-party software and services, including Avalonia, .NET, FFmpeg, GitHub, and Cloudflare Web Analytics on the website. Third-party software and services are governed by their own license terms, privacy policies, and operational practices.

The Developer is not responsible for third-party services, content, service availability, security incidents, policy changes, or data practices outside the Developer's control.

Security

Transmux is designed to keep app data local by default, but no software, operating system, network, storage medium, or third-party service can be guaranteed completely secure. You are responsible for securing your device, backups, synced folders, user account, downloads, and files.

Children's Privacy

Transmux is a general-purpose desktop media converter and is not directed to children. The Developer does not knowingly collect personal data from children through the Transmux app.

License and Usage Terms

Transmux source code is publicly viewable but is not open source under any OSI-approved license. The following apply:

• Permitted: view the source, download/install/use official releases for personal non-commercial purposes, build from the official source repository for personal evaluation/testing/contribution, and contribute through the official repository.

No Warranty

Transmux, the website, release downloads, update checks, documentation, and support channels are provided on an "as is" and "as available" basis, without warranties of any kind, whether express, implied, statutory, or otherwise.

Limitation of Liability

To the maximum extent permitted by applicable law, the Developer shall not be liable for any direct, indirect, incidental, consequential, special, exemplary, or punitive damages, including loss of data, loss of files, conversion failures, device issues, security incidents, business interruption, loss of profits, or reputational harm arising out of or related to Transmux.

Indemnification

You agree to indemnify, defend, and hold harmless the Developer from any claims, damages, liabilities, losses, and expenses, including legal fees, arising out of or related to:

• Your use or misuse of Transmux, the website, release downloads, or support channels.
