Privacy Policy
FormulaLib provides free browser-based calculators. This page explains what information may be processed when you use the site.
Calculators run in your browser
Calculator inputs and results are processed on your device. We do not operate a backend that stores your calculation values for these tools.
Hosting and security
The site is hosted on Cloudflare. Cloudflare may process technical request data (such as IP address, user agent, and timestamps) to deliver pages, protect against abuse, and operate DNS and CDN services. See Cloudflare’s own privacy documentation for details of their processing.
Analytics
We may use privacy-oriented or host-provided analytics (for example Cloudflare Web Analytics) to understand aggregate traffic patterns. These tools are intended to measure visits and performance, not to build marketing profiles of individual visitors.
Advertising
We may display third-party advertisements (including networks such as Adsterra) on some pages. Ad partners may use cookies, pixels, or similar technologies to serve ads, measure delivery, and limit how often you see the same creative. Those partners process data under their own policies.
You can limit cookies and tracking through your browser settings. Blocking third-party cookies or using an ad blocker may hide ads but will not prevent the calculators from working.
Contact and email
If you email [email protected], we receive the address and message content you send so we can reply. We do not sell personal data.
Changes
We may update this policy when hosting, analytics, or advertising setup changes. The “Last updated” date at the top of this page will change when we do.
