This Privacy Policy explains how BestCalculate ("we", "us") handles information when you use our website. We designed the site to collect as little as possible.
Calculations stay on your device
Our calculators run entirely in your web browser. The numbers and values you enter into any calculator are processed locally and are not transmitted to or stored on our servers.
Information we collect
We may collect limited, non-identifying analytics data — such as pages viewed, approximate region, browser type and referring site — to understand how the site is used and to improve it. We do not use this data to identify individuals.
Google Analytics 4 (GA4)
When enabled, we use Google Analytics 4 to understand page visits and calculator actions, such as calculating, resetting and copying an embed snippet. Calculator events include only the calculator identifier, category, a general unit-system label and the action method. We do not send your entered values, calculation results, generated passwords or shared result text in these events. Page URLs sent by our integration exclude query strings and fragments.
Analytics loads only when enabled on the production site. Analytics and advertising storage default to denied for all visitors, including those in the EEA and UK. Consent Mode may send cookieless measurement pings while consent is denied. Storage is granted only after an explicit consent choice. Use Cookie settings in the footer to accept, reject or withdraw analytics consent. We store your choice on your device for up to 180 days. Rejecting analytics does not affect calculator access. Advertising consent remains denied. Google processes measurement data under its Privacy Policy.
Cookies and advertising
We may use cookies for basic functionality and analytics. If we introduce advertising, third-party ad providers (such as Google) may use cookies to serve ads based on your prior visits to this or other websites. You can opt out of personalized advertising through Google's Ads Settings and viaaboutads.info.
Third-party services
Some third-party services we use (for example, analytics or advertising providers) may collect information in accordance with their own privacy policies. We encourage you to review those policies.
Children's privacy
Our site is not directed to children under 13, and we do not knowingly collect personal information from them.
Your choices
You can block or delete cookies through your browser settings, and use browser privacy features at any time. Doing so will not affect the core functionality of our calculators.
Changes to this policy
We may update this policy from time to time. Material changes will be reflected by the "last updated" date above.
