Privacy and cookies

Last updated: September 25, 2026.

Calculator inputs

Our calculator code processes inputs in your browser and does not send the entered amounts or calculated results to a SmallBiz Lab database. You can use the calculators without an account. Avoid entering personal identifiers or confidential records.

Website hosting and accounts

Cloudflare serves this website and may process technical request information, including IP addresses, to deliver and protect it. If you use the optional account features, Supabase processes the account details you submit and stores authentication session information in your browser. Calculator use does not require registration.

Analytics

When Google Analytics is enabled, it measures page visits and interactions such as starting or completing a calculation. Our custom calculator events include the calculator name and input count, not the amounts entered or results. Google may process device, browser, cookie, and network information. You can use browser privacy settings or Google’s analytics opt-out tools to limit collection.

Advertising and cookies

When Google AdSense is enabled, Google and other advertising partners may use cookies or similar technologies to serve and measure ads. Advertising cookies can support personalized ads based on visits to this and other websites. Where a consent message is shown, use its controls to accept, reject, or manage the available purposes and partners.

You can manage Google ad personalization at My Ad Center and learn how Google uses information from partner sites in Google’s explanation. Browser settings can also remove or restrict cookies, which may affect account features.

Third-party services and your choices

Third-party services handle information under their own policies: Cloudflare, Supabase, and Google. This page describes the site’s features; availability depends on which services are enabled.
