Privacy policy

Snow day calculator: to get a forecast, the ZIP code or town you type (or your approximate location, if you choose “Use my location”) is sent to Zippopotam.us and Open-Meteo. Nothing else about you is sent, and Calcora does not store it. Your last search is remembered in your own browser so you don't have to retype it.

What you type stays on your device

All calculations happen in your browser. Grades, GPAs and dates you enter are not sent to our servers or stored by us. Your light or dark theme choice is saved in your browser's local storage so the site remembers it.

Analytics and advertising

We may use privacy-respecting analytics to count visits and see which tools are popular. If we show ads, our advertising partners, such as Google, may use cookies to serve ads based on your visits to this and other websites. You can opt out of personalized advertising at Google's Ads Settings page or at aboutads.info.

Children

Our calculators are general-audience tools and do not knowingly collect personal information from anyone.
