Privacy Policy

Last updated: October 26, 2026

This policy explains what information Pro100 Calculators ("we", "us"), available at https://calc.pro100.sarl, collects when you use the website and how it is used.

Information we collect

Numbers you enter. All calculations run in your browser. The values you type into the calculators are not sent to our servers or stored by us.
Technical data. Our hosting provider (Cloudflare) processes IP addresses, browser type and request logs to deliver the site and protect it from abuse.
Analytics. We may use privacy-friendly, cookieless analytics (Cloudflare Web Analytics) to count visits.
Advertising. We may show ads from Google AdSense. Google and its partners may use cookies to serve ads based on your visits to this and other websites. You can opt out of personalized advertising at Google Ads Settings.

Third-party services

Pages may contain links to third-party websites, including affiliate links. When you follow them, the privacy policy of that website applies.

Cookies

The site itself does not require cookies to work. Advertising partners may set cookies as described above. Your browser lets you block or delete cookies.

Data retention

We do not keep the numbers you enter. Our hosting provider keeps short-lived technical logs.

Children

The service is not directed to children under 13 and we do not knowingly collect their personal data.

Your rights

Depending on where you live (for example under the GDPR or CCPA) you may have the right to access, correct or delete personal data. Contact us at [email protected] and we will respond within 30 days.
