What Tungs is

Tungs is a desktop app that installs two virtual audio devices, Tungs Microphone and Tungs Speaker. You select them inside a calling app such as Zoom, Google Meet, Microsoft Teams, FaceTime, WhatsApp, Discord or Webex. You speak in your language and the other person hears yours translated; they answer in theirs and you hear it in yours. The person you are talking to installs nothing.

It requires an internet connection and runs on macOS 14 or later, and on Windows 11 from 11 November 2026. There is no iPhone or Android version. The person on the other end can be on any device.

The free trial

The first 10 minutes of translation are free. No account, no card, nothing to cancel. The trial is one per computer and is meant for trying the product out.

The subscription

Tungs is $19.99 per month or $199 per year. Either plan includes 120 minutes of translation every month. Minutes are counted only while a translation session is actually running.

Included minutes reset at the start of each billing month and do not carry over: minutes you do not use are not refunded or banked. The subscription renews automatically until you cancel it, and you can cancel at any time from the billing page Tungs links to. When you cancel, you keep the minutes already included in the period you have paid for, and the subscription ends when that period ends.

Extra minutes

If you run out before the month does, Tungs offers 60 more minutes for $9.99 inside the app. It is a one-off purchase, available to subscribers, and those minutes do carry over: they stay on your account for a year from the day you buy them, including after a subscription ends.

Using your own OpenAI key

Any subscription also lets you run Tungs on your own OpenAI API key instead. While you do, the translation is billed to your OpenAI account by OpenAI, at their rates, and we are not in the middle of it — nothing is metered on our side and your included minutes simply sit unused. You are responsible for your own OpenAI usage and costs. You can switch back to your Tungs minutes at any time in the app.

Earlier purchases

Minutes packs and yearly licenses bought before Tungs became a subscription keep working exactly as they did, on the terms they were bought under. Licenses keep renewing at their original price until cancelled. Neither is sold any more.

Your account and your code

When you buy, we email you a 20-character account code. It is what restores your purchase on a new computer, after a reinstall, or if something goes wrong — enter it under "Restore my purchase". Keep it; treat it like a receipt. If you lose it, the app can email it to you again, and so can we.

Your purchase is for you. Please do not share the code around.

What translation can and cannot be relied on for

Tungs is machine translation, and machine translation is wrong sometimes. It mishears, it guesses at names, it flattens idiom and it can miss a negation that reverses a sentence. It is good enough to have a real conversation with someone whose language you do not speak. It is not good enough to be the only thing standing between you and a serious decision.

Do not rely on it alone for medical, legal, financial or safety-critical conversations, and do not use it for emergency calls. Where accuracy has consequences, use a qualified human interpreter.

Recording and consent

Tungs can record a call, but only when you press record. Whether you may lawfully record a conversation depends on where you and the other people are, and in many places everyone has to agree first. That is your responsibility, not ours. Recordings are written to your own computer and we never receive them — see the privacy page.

Fair use

Do not use Tungs to break the law, to deceive someone about who they are talking to, to harass anyone, or to intercept conversations you are not part of. Do not resell access, and do not try to pull the service apart — reverse engineering it, hammering it automatically, or working around the minutes.

Availability

We will keep Tungs running and keep improving it, but we do not promise it will never be down. Translation depends on OpenAI's service, and when that is degraded Tungs is degraded with it. If we ever have to stop offering the product, we will tell you and deal fairly with unused minutes.

The legal part

Tungs is provided as it is, without warranties beyond those the law gives you and does not let us exclude. To the extent the law allows, our total liability to you for anything connected with Tungs is limited to what you have paid us in the twelve months before the claim. Nothing here limits liability for fraud, or for anything else that cannot lawfully be limited.

The software stays ours. Buying minutes or a license buys you the right to use it, not ownership of it.

If we change these terms we will update the date at the top. Continuing to use Tungs after a change means accepting it; if you do not, ask us for a refund.
