Live Caption

Privacy policy

Effective 20 October 2026

Live Caption is an app for macOS and Windows, made by SK Global, that shows captions and translations of the audio on your computer. This page explains what happens to your audio, your text and your data, and what SK Global receives.

In short

• With the on-device setup, audio and text never leave your computer.
• With a cloud service you chose, the app sends audio or text straight to that service, with your own key. It does not pass through us.
• The app never records audio.
• We do not sell data, show ads or track you across apps or websites.

What stays on your computer

• Audio from the microphone or the computer is processed in memory to make captions, then discarded. It is never saved to a file.
• Sessions: when a session ends, the app asks whether to save its transcript and summary. If you agree, they are saved as a file in the folder you choose. Nothing is saved otherwise.
• Settings, term lists and downloaded models are stored on your computer.
• API keys for cloud services are kept in the system’s password store (Keychain on macOS, Credential Manager on Windows), never in a settings file.

Cloud services you choose

Cloud setups are off unless you choose one in Settings and enter your own API key. Then the app sends data directly from your computer to that provider, over an encrypted connection:

• OpenAI: audio, to be transcribed; text, to be translated or summarized and to build term lists.
• Google (Gemini): audio, to be transcribed and translated.

These requests are billed to your account and handled under the provider’s own terms and privacy policy (OpenAI, Gemini API). Some free plans let the provider use what you send to improve its services; check your plan.

When you give the app slides or documents to prepare a term list, it reads their text on your computer and shows it to you first. It is sent to a cloud service only after you agree, and only if you use one.

What SK Global receives

This computer’s setup, once

Once per installation, the app sends us a description of the computer so that its suggestions fit real machines: chip, number of cores, memory, graphics card, free disk space, operating system, app version, the languages and models you chose, and the speed test results. It contains nothing heard or shown, no name, email or key. You can turn it off during setup or in Settings › About › Checks before it is sent.

Reports you send

Settings › About › Report content lets you report AI-made content that is wrong or inappropriate. A report contains what you paste and write, your email if you leave one (only to reply to you), and the app version, operating system type, interface language, and the languages and models in use. We use reports to check and improve the app.

Update checks

Once a day the app asks our server whether a new version exists, and downloads it if you choose to update. We count downloads per version; the requests do not identify you.

The download page

To download the app from livecaption.sk-global.io you sign in with Google. We keep your email, name, and when and which version you downloaded, to know who is using the app and to limit abuse. We do not share it with anyone. The “Delete my data” link on that page deletes this record and your sign-in account at once.

Network addresses

Like any server, ours see your IP address when the app or the page connects. We do not store it with what you send: to limit how many reports one network sends a day, we keep a one-way code of it with the day’s count; the address cannot be recovered from that code. Our hosting provider may keep it briefly in its own logs.

Model downloads

The speech and translation models are downloaded, when needed, from Hugging Face, GitHub, Moonshine AI and Google Cloud Storage. These sites see your IP address, as with any download. Nothing about you is sent with the request.

Where data is stored, and security

What we receive is stored with Google Firebase (Cloud Firestore, Singapore region). Only SK Global’s team can read it. Everything the app and the page send travels over HTTPS.

Children

Live Caption is not directed at children under 13, and we do not knowingly collect their data.

Your choices

• Use the on-device setup to keep audio and text on your computer.
• Turn off sending this computer’s setup (Settings › About › Checks).
• Delete your download-page data with “Delete my data” on that page.

Changes

If this policy changes, the new version is posted here with a new date. Significant changes are also noted in the release notes.
