Chatcha has no accounts. Your game state, streak, and preferences live in your browser's local storage and never leave your device — clear your browser data and they're gone.
When you send a text in-game, the conversation is sent to our AI provider (OpenRouter and the model behind it) to generate the reply and score the turn. Don't type anything you wouldn't want processed by a third-party AI service. We don't store your conversations on our servers.
We use privacy-friendly analytics (page views, no cross-site tracking) to understand how the game is used.
