PRIVACY

Your words stay yours.

Only when you tap

Text leaves your phone only when you choose Fix, Translate or a Style.

No app account

You don’t need an account to use CatWrite. We ask for your email to send a beta invitation.

When you tap Fix, Translate or a Style, your selected text is sent directly to Google Gemini for processing. CatWrite does not save that text in the app.

We use Gemini’s paid API. Under Google’s paid-service terms, prompts and responses are not used to improve its products. Google may keep logs for a limited time for safety and abuse monitoring.
