Privacy Policy
Last updated: July 13, 2026
The short version
- No account required — use every calculator without signing up or logging in.
- We do not collect your data — numbers you enter stay in your browser and are not sent to our servers or stored in a database.
- Cookies are optional — we ask for your cookie consent on your first visit. Advertising only loads if you accept cookies.
Who we are
Calcuit provides free online calculators for finance, health, and related topics. This policy describes what happens when you visit our website.
No accounts, no sign-up
We do not offer user accounts, subscriptions, or login. You never need to provide your name, email address, or other personal details to use our calculators.
Calculator information stays on your device
When you use a calculator, the values you type (such as weight, height, loan amount, or income) are processed locally in your web browser to produce results. We do not transmit those inputs to our servers, and we do not maintain a database of what you calculate.
Contact form
If you use our contact form, you choose to send us your name, email, subject, and message. That information is transmitted through EmailJS to deliver your message to us — we only receive what you submit in the form.
What we store locally
The only preference we save in your browser is your cookie consent choice (accept or reject). This is stored in your device's localStorage so the consent banner does not appear on every visit. We do not receive this choice on our servers — it remains on your device.
Optional advertising (Google AdSense)
If you choose Accept cookies, we may load Google AdSense to show advertisements. Google and its partners may use cookies or similar technologies to serve and measure ads, including ads based on your prior visits to this or other sites. That processing is governed by Google's policies, not ours.
If you choose Reject cookies, AdSense scripts are not loaded and ad slots are hidden. All calculators remain available with no loss of functionality.
You can manage Google ad personalization at Google Ads Settings and read how Google uses data from partner sites at Google's partner policy.
Hosting and technical logs
Our hosting provider may automatically record standard technical information when you request a page (such as IP address, browser type, and timestamp) for security and reliability. We use this only to operate the site, not to build profiles of individual users or link activity to calculator inputs.
Children's privacy
Our site is intended for a general audience. We do not knowingly collect personal information from children. Calculator tools are informational only and are not a substitute for professional medical or financial advice.
Changes to this policy
We may update this page from time to time. The "Last updated" date at the top will change when we do. Continued use of the site after changes means you accept the revised policy.
