Privacy Policy

The AI Graphing Calculator is designed to work without collecting your personal data. This policy describes, in plain terms, what happens with your information.

What we collect

Nothing by default. There are no accounts, no sign-ups, and no analytics. Browsing the site, plotting functions, and saving graphs send no usage data, identifiers, or personal information to any server.

AI assistant

When you send a message to the AI math assistant, your message and a compact summary of your current calculator state (expressions, viewport) are sent to the site’s own server endpoint (/api/ai/math). If an AI provider key is configured, the server forwards your message to the AI provider (DeepSeek) to generate a response. The server never logs your messages or any API key; rate-limiting state is kept only in memory and expires within minutes.

When no provider key is configured, the assistant runs in a clearly labeled mock mode: responses are generated by deterministic local logic and no AI provider is contacted. Local intents (for example, “plot y = x^2”) are handled entirely in your browser and never reach a server.

Cookies

The site sets no cookies and uses no third-party trackers. Because there are no analytics and no advertising, there is no cookie banner and no consent to manage.

What stays in your browser

Your theme preference and your calculator workspace (expressions, viewport, settings) are stored only in your own browser’s localStorage. They never leave your device. Clearing your browser’s site data removes them permanently.
