Calculator inputs
Tabutility calculators are designed to process the figures you enter in your browser. Tabutility does not require an account and does not intentionally send calculator inputs to its own servers for calculation. Do not enter confidential identifying information into any online calculator.
Usage analytics
Tabutility uses Google Analytics to understand page visits, approximate location, device and browser information, referral sources and site performance. Google may use cookies or similar technologies. Analytics data is used to find errors and improve the site.
Advertising and affiliates
The site contains Google AdSense code for review and may display advertisements if approved. Google and its partners may use cookies or similar technologies subject to applicable consent requirements. Some clearly disclosed links are affiliate links; a third party may record a visit or purchase after you follow one.
Infrastructure
Cloudflare and Vercel provide DNS, security and hosting and may process routine request information such as IP address, user agent and timestamps for security and service operation.
Your choices
You can restrict cookies through browser settings and use any consent controls presented on the site. Blocking analytics or advertising scripts does not prevent the calculators from performing their core calculations.
