This Privacy Policy explains what information LensMath (speedboostercalculator.com) collects when you visit the site and how that information is used. Last updated: October 1, 2026.
Information we collect
Calculator inputs: the numbers you type into our calculators are processed in your browser. They are not sent to or stored on our servers.
Analytics: we use Google Analytics 4 to understand how the site is used. It collects usage information such as the pages you view, your approximate location, your device and browser type, and the page that referred you. Google states that Google Analytics 4 does not log or store individual IP addresses.
Server logs: our hosting provider, Hostinger, keeps standard server logs that include IP addresses, browser type, and date and time of requests. We use them for security and troubleshooting.
Messages: if you email us, we receive your email address and whatever you choose to include in your message.
Cookies
Google Analytics uses cookies to tell visits and visitors apart. You can block or delete cookies in your browser settings, or install the Google Analytics opt-out browser add-on. You can read how Google handles data from sites that use its services on Google’s privacy page.
How we use information
We use it to see which tools and guides are useful, improve and fix our calculators, keep the site secure, and reply to your messages. We do not sell personal information, and the site does not currently show advertising.
Who we share it with
We share information only with the service providers needed to run the site: Google (analytics) and Hostinger (hosting). We may also disclose information if the law requires it.
Links to other websites
Our pages link to external sites such as reference articles. We do not control those sites and are not responsible for their privacy practices, so please read their policies.

Depending on where you live (for example under the GDPR, UK GDPR or CCPA), you may have the right to ask what personal information we hold about you, and to ask us to correct or delete it. To make a request, email us using the contact details below.
