Privacy Policy

What we collect

All Type Calculator does not require an account. We do not ask for your name, email address, or any other personal information to use any calculator on this site. There are no user registrations, comments, or profiles.

Calculations stay on your device

Every calculator on this site runs entirely in your browser as JavaScript. The numbers you type into a calculator, the results it produces, and the history panel are never sent to our servers. If you clear your browser storage, calculator history and any UI preferences (such as light/dark mode) are erased.

Cookies and local storage

We use localStorage only to remember your light/dark theme preference so you don't have to set it on every visit. We do not set any tracking cookies, and we do not use third-party advertising cookies.

Analytics

Our hosting provider records standard web server logs (approximate location, request time, user agent) for operational purposes such as protecting the site from abuse and diagnosing outages. These logs are not linked to any personal identity and are not used for advertising.

What we never do

• We do not sell, rent, or share your data with third parties.
• We do not run third-party ad networks on this site.
• We do not embed social-media tracking pixels.
• We do not fingerprint your browser for tracking.

Changes

If this policy changes, the "Last updated" date at the top of the page will change too. Material changes will be described in a short note on the homepage for a reasonable time.
