Privacy in plain language
You can use the calculators without creating a profile. Calculations run on the page in your browser rather than through a dedicated calculation API. Some features can preload values through URL parameters, so those values may be included in browser history and standard server requests.
- Do not enter sensitive information that a calculation does not require.
- The Google tag loads with analytics storage denied by default; analytics cookies and full measurement begin only after Analytics is accepted.
- Theme preference, scientific-calculator history, and cookie choices may remain in your browser.
- Emailing us sends the information you choose to include to our contact inbox.

What we do not do
The site is intentionally usable without building a personal profile.
- We do not require an account for calculator use.
- We do not sell calculator inputs or contact details.
- We do not save calculator results in a user account or calculator database.
- We do not use calculator results to make significant automated decisions about users.
- We do not allow Google Analytics cookies before Analytics consent, and advertising services are not currently active.
Service providers and optional Google services
Hosting, content-delivery, and network-security providers may receive information normally included in a web request, such as IP address, requested URL, browser information, and timestamp. They process it to deliver and protect the site. The Google tag uses Consent Mode with analytics storage denied by default. Before consent, Google may receive limited cookieless consent and measurement signals; analytics cookies and full visit measurement begin only after Analytics is accepted. Google AdSense is not currently configured.
- Analytics and Advertising can be accepted or rejected separately in Cookie settings.
- A saved choice can be changed later from the site footer.
- Google Analytics uses measurement ID G-TXR28JGGQ9.

Providers may process information in countries other than yours, subject to their safeguards and applicable transfer rules.
