Privacy Policy
Last updated October 2, 2026
Fluent translates what you give it and keeps as little as it can. There are no ads, we don't sell data, and we don't track you across other apps or sites. Nobody at Fluent reads your translations.
What Fluent needs to work
- A sign-in. Your name and email, so your account is yours. Sign-in is handled by Clerk.
- What you ask it to translate. The text you type or share, and audio when you use the microphone. Audio is turned into text, translated, and not used for anything else.
Who helps
Fluent passes your text or audio to a few services so they can do their part:
- OpenAI, the makers of ChatGPT, and Google produce the translation.
- Cartesia produces the spoken voice.
- Convex runs our servers and Clerk manages accounts.
They receive only what's needed for that request. None of them use your content to train their models.
How long things stay
- A translation is held on our servers for up to 24 hours, so one that gets interrupted can finish. Then it's removed.
- Your history and saved phrases live on your phone.
- If you chat with another Fluent user, your messages are stored so you can both read them.
Helping improve translations (optional)
This is off unless you turn it on. If you do, examples of your translations are kept for 30 days so we can study where Fluent gets things wrong, and that's the one case where we may read them. Turn it off any time and those examples are deleted.
Deleting your account
Settings → Delete Account removes your account and what's tied to it. You can also email us.
Children
Fluent isn't meant for children under 13, and we don't knowingly collect data from them.
Changes
If this policy changes in a way that matters, we'll update the date above and note it in the app.
