Honest answers, in plain language.

At launch, anything Gemini can translate confidently between, which is most of the languages on Google Translate. We’re prioritising Tagalog, Thai, Spanish, Mandarin, Arabic, Japanese, Portuguese, French, German and Korean in the first months. If your pair isn’t there yet, write to us and we’ll let you know when it lands.

Yes. Both sides need the app for the translation to happen on the way through. NatChatt is on the App Store and Google Play; once you’re inside, you can invite someone from your contacts with one tap.

You can read your existing messages offline. Sending or receiving a new translation needs an internet connection, because the translation runs through Google’s servers. We don’t store a copy of the model on your phone.

Captions usually appear inside two seconds of someone speaking, depending on connection. For a steady call it feels close to real time. We’re honest about it being captions, not a synthesised voice; you still hear the person you’re talking to in their own voice.

The app itself is free to download and use, and every pack comes with a batch of free chat translations. Credits mainly cover translated voice calls — and keep your chat going once the free allowance runs out. You get 15 free credits on signup, no card needed. Every pack you buy includes 1,000 free chat translations — text and voice notes both count. See the full pack list on the pricing page.

Credits cover live translation. A translated voice call uses one credit for every two minutes. Every pack also comes with a batch of free chat translations (text and voice notes); once those are used up, chat simply draws on your credits — roughly 100 text messages or 20 voice notes per credit. The price covers the API cost plus a small platform fee for payment processing, infrastructure, and support. No subscription, no markup on usage, no surprises.

Yes, up to 1,000 translations with every pack you buy. Text messages and voice notes draw from the chat allowance that comes bundled with each pack. The allowance never expires — buying a new pack simply adds more on top. Almost nobody hits the cap; if you do, the next translations come out of your credit balance — about 100 text messages or 20 voice notes per credit.

One credit covers two minutes of translated voice call. The app shows your remaining minutes on the call screen and warns you when you’re close to running out so you’re never cut off mid-sentence.

Credits don't expire, and neither does your free chat allowance. Top up once and use both whenever you like — a week, a year, or three years from now. Every pack you buy simply adds more on top.

Refunds cover paid credits only — the free chat translations bundled with every pack are a gift, never charged for, and so never refunded. If you haven't used any of the purchase, you can claim a full refund within 14 days. The moment you use even one credit from a purchase, that purchase becomes non-refundable: we don't refund partially, and the remaining credits stay on your account to use whenever you like. Any other untouched purchase is still fully refundable — and since credits never expire, there's no rush to spend them. After you delete your account, you can keep using your balance whenever you come back.

The app shows your credit balance on the chat screen and itemises every call under usage history (with the minutes used). Chat translations show up too, drawn from the allowance bundled with your current pack. You can set a low-balance alert so you’re never surprised, and you can stop topping up at any time — there’s no subscription to cancel.

On your phone and on the phones of the people you’re writing to. We don’t keep a copy on our servers. For end-to-end encrypted messages, the only versions of a conversation that exist are the ones on the devices that took part in it.

Gemini processes your message text or audio at the moment of translation. According to Google’s API terms, that data is not used to train their public models when accessed through the paid API. The translation is returned and the request is dropped. We don’t hold on to the request or response on our side.

No. We never see the contents of your conversations. If you write to support, we only see the message you send to support.

There’s no password to remember. NatChatt uses your phone number to sign in. Open the app, enter your number, and we’ll send you a one-time code by SMS. Tap the code and you’re back in, with your contacts and settings as you left them.

In the app, settings, account, delete. Or write to us via the /delete-account page on this site. We process the request inside seven days and send confirmation when it’s done. One thing to know first: because your messages live on your phone and not on our servers, deleting your account (or uninstalling the app) removes your chat history with no way for us to restore it. The on-device export tool that would let you back things up first is something we’re still building.

Not yet, and we want to be honest about it. Your messages live on your phone, not on our servers, so an export has to happen device-side — we haven’t built that tool yet. It’s on the roadmap and we’ll add it in a future release. In the meantime, anything you’ve already sent or received stays on your device until you delete it.
