Privacy policy

CalcLearn has no accounts, no sign-ups, and collects no personal information. You can use every page and tool on this site without telling us anything about yourself.

Analytics

We use privacy-respecting analytics to understand which pages help students: Vercel Analytics (anonymous, cookie-free page views) and, if enabled, Google Analytics 4 configured with IP anonymization and with advertising features and Google Signals disabled. None of this data identifies you personally, and none of it is used for advertising or profiling.

Local storage

Interactive tools may store settings (like a chosen function or slider position) in your own browser's local storage so the page remembers where you left off. That data never leaves your device.

Contact

Questions about this policy can be sent through the contact information on the About page of EconLearn (econlearn.org), our sister site.
