Privacy Policy
Last updated: July 8, 2026
Calculus Solver is an educational tool. We do not require user accounts, and we do not collect personal information beyond what is described below.
Information We Process
When you submit a math problem, it is sent to our server-side API route and forwarded to DeepSeek for processing. Your API key is never exposed to the browser.
Local Storage
Your recent problem history is stored only in your browser's localStorage. It is not transmitted to our servers and remains under your control.
Cookies
Calculus Solver does not use first-party cookies. We rely on minimal analytics that may use anonymous cookies to understand overall traffic. No personal data is stored in these cookies.
Data Retention
We do not retain math problems or results on our servers after they are processed. If local history is enabled, it is kept in your browser until you clear it or uninstall the application.
Third-Party Services
We use DeepSeek for AI math reasoning. Please refer to DeepSeek's privacy policy for information about how they handle API requests.
