Privacy Policy
Last updated: 2026
The short version: your numbers stay on your device. CalcLioro has no accounts, no database of user inputs and no advertising trackers.
Information we do not collect
We do not ask for your name, email address, phone number or payment details, because nothing on this site requires an account or a payment. We never receive the values you type into a calculator. Every calculation is performed by JavaScript running inside your own browser, so figures such as your salary, loan balance, weight or grades are never transmitted to us and are never written to any server.
What is stored on your device
One item is saved in your browser's local storage: your light or dark theme preference, so the site looks the way you left it. It contains no personal information and is readable only by this site. Clearing your browser data removes it.
Cookies and analytics
CalcLioro sets no advertising cookies and runs no cross-site tracking scripts. Our hosting provider may keep standard server logs, which can include IP addresses, request times and user-agent strings, for security and reliability purposes. These logs are not used to build profiles of visitors or joined to any calculator input.
Third parties
Web fonts are loaded from Google Fonts, which means your browser makes a request to Google's servers to fetch the typeface. No other third-party service receives data from this site. We do not sell, rent or share information with data brokers, because we do not hold any to share.
Children's privacy
The site is suitable for general audiences, including students using the GPA and grade calculators. Because we collect no personal information from anyone, we collect none from children either.
Your rights
Regulations such as GDPR and CCPA give you rights of access, correction and deletion over personal data a site holds about you. Since CalcLioro holds no personal data, there is nothing for us to export or erase. You remain in full control of the theme preference stored locally in your browser.
Accuracy and liability
Calculator results are estimates provided for information only and are not financial, medical, tax, legal or other professional advice. Verify important figures with a qualified professional before acting on them.
Changes to this policy
If our practices change — for example if privacy-respecting analytics are added — this page will be updated and the date at the top revised before the change takes effect.
