Overview
FastCalcs provides browser-based calculators. Most calculator values you enter are processed in your browser and are not sent to a FastCalcs account or database.
Analytics
We use analytics tools such as Google Analytics and Cloudflare Web Analytics to understand page views, countries, devices, traffic sources, and site performance. These tools may collect information such as your browser type, approximate location, pages visited, referrer, and interaction data.
Advertising
FastCalcs may use Google AdSense or other advertising services. Advertising partners may use cookies or similar technologies to serve and measure ads. Google may use cookies to personalize ads based on visits to this and other websites, depending on your settings and local law.
Cookies
Cookies and similar technologies may be used for analytics, security, performance, and advertising. You can control cookies through your browser settings. You can also manage Google ad personalization in your Google ad settings.
Third-party services
FastCalcs may include scripts or services from Google, Cloudflare, and other infrastructure or advertising providers. Their handling of information is governed by their own policies.
No professional advice
Calculator results are estimates for general information. They are not financial, medical, tax, legal, construction, or professional advice.
Changes
We may update this policy as the site changes. The latest version will be posted on this page.
