Privacy Policy

Information We Don't Collect

At Calculators Directory, we prioritize your privacy. The vast majority of our calculators run entirely in your local browser environment. We do not store, see, or transmit any of the numerical data or personal values you input into our calculation tools.

Analytics & Cookies

We use Google Tag Manager (with Google Analytics), and self-hosted analytics (Umami) to understand general usage patterns, such as which tools are most popular. Analytics data is used in aggregate and is not sold to third parties.

Favorites & Shared Links

If you favorite a calculator or use the share link feature, that data is stored locally in your browser (favorites) or encoded in the URL you choose to share (share links). We do not store your calculator inputs or favorites on our servers unless you are signed in and we explicitly offer account sync in the future.

Anyone with a shared link can see the calculator inputs encoded in that URL. Shared links are optional — you control when you copy and send them.

Account Information

If you choose to create an account via Clerk, we store your email address and basic profile information solely to provide personalized features, such as saving your custom settings or favorite calculators.
