BridgeSub Privacy Policy

Effective date: 1 October 2026

Who is responsible

BridgeSub is made by i4x Studio, a business registered in Poland (CEIDG), NIP 1182004411. Contact: support@i4xstudio.com.

Summary

BridgeSub is a subtitle workbench for your Mac. Your movies and audio never leave your Mac. Subtitle text leaves your Mac only when you start a translation and confirm the provider it goes to. The app contains no advertising, cross-app tracking, or analytics SDKs, and i4x Studio receives none of your data.

What stays on your Mac

• Media and subtitle files you choose. BridgeSub inspects movies, parses subtitles, analyses timing, runs speech recognition on the device, merges tracks, and exports files, all on your Mac. When you choose a folder, BridgeSub lists that folder only, not its subfolders, to find the movie and the subtitle files next to it.
• Stored items. Preferences, subtitle drafts, downloaded models, and caches are kept in the app's container or in locations you choose. The Recent list keeps a read-only bookmark to the folder you chose and the movie's file name.
• Credentials. API keys for translation providers are stored in the macOS Keychain.
• Diagnostics. Diagnostic events stay in a limited local log. If you export a diagnostic bundle, it goes only to a folder you choose, with subtitle text, prompts, responses, and credentials removed. BridgeSub never uploads it.

What leaves your Mac, and when

Translation. Before each new translation run, BridgeSub shows the provider and address it will use and asks you to confirm. Only then does it send the selected subtitle text, the source and target languages, any context you entered, and the translation instructions. The provider can be a service on your own network, such as Ollama, or a cloud service you configured with your own key. That provider's privacy and retention terms apply to what it receives; i4x Studio does not receive it.

Model downloads. When you ask for an optional model, BridgeSub downloads it from the host named in the app. Like any download, the host sees your IP address.

Deleting your data

Delete exported files in Finder. In Settings you can clear the speech-recognition cache and remove each downloaded model. Deleting BridgeSub's folder in ~/Library/Containers removes its preferences, drafts, models, and caches. Remove API keys in the app or in Keychain Access. For text already sent to a translation provider, use that provider's deletion process.

Your rights

i4x Studio holds no personal data from the app. If you email us, the website privacy policy at https://i4xstudio.com/privacy/ applies to your message, including your rights and how to complain to the supervisory authority.

Changes

We will post any change to this policy on this page and update the effective date.
