1. Summary — what we do and don't collect

Calculator On Screen is a public site that provides browser‑based calculators. We do not collect or store personal information from visitors for the operation of the calculators. There is no user account system, and we do not ask for or retain names, emails, phone numbers, or other personal data for calculator usage.

2. How the calculators work

All calculators on calculatoronscreen.com run in your browser. Inputs you enter into a calculator are not sent to our servers by default.

3. Third‑party advertising and cookies

We may display advertisements provided by third‑party advertising networks. These third parties may use cookies, web beacons, and similar technologies to collect information about visitors to deliver personalised ads and measure ad performance.

We do not control the data collection practices of these third parties.

4. Cookies — what they are and how we use them

A cookie is a small text file stored on your device by your browser. We do not set tracking cookies on our own. However, third‑party services embedded on the page (ads, fonts, etc.) may set cookies.

5. Children's privacy

Our site is intended for general audiences and not directed at children under 13. We do not collect personal information from children.
