The short version

Information we collect

Analytics. We use Cloudflare Web Analytics, which counts page views and measures page speed without cookies and without tracking you across sites. It records aggregated information such as the pages visited, referring site, country, browser and device type.

Server logs. Like most websites, our hosting provider (Cloudflare) automatically processes technical data needed to deliver and protect the site, such as IP address, browser type, date and time, and the page requested. This is used for security and reliability, not to identify you.

Email. If you email us, we receive your address and message and use them only to reply. We keep them for as long as needed to handle your message.

Grow by Mediavine. We use Grow, a service from Mediavine, Inc., that can let you save or bookmark pages and sign up for updates. It loads a script from grow.me and may store information in your browser (such as cookies or local storage) to remember your choices and measure how the site is used. If you create a Grow account or subscribe, Mediavine processes that information under its own privacy policy: mediavine.com/privacy-policy.

Cookies and advertising

Supply Math itself does not set tracking cookies. We may show ads to keep the site free. Ad providers, such as Google, its partners, and ad management companies, may use cookies, web beacons and similar technologies to show ads, limit how often you see them, and measure their performance. These may be based on your visits to this and other websites.

Google’s use of advertising cookies enables it and its partners to serve ads based on your visits to this and other sites. You can learn how Google uses information from sites that use its services at policies.google.com/technologies/partner-sites, and opt out of personalized advertising at adssettings.google.com or aboutads.info/choices.

When ads are active, visitors in the European Economic Area, the UK and Switzerland are asked for consent through a certified consent message before personalized ads are shown, and can change their choice at any time.

Your rights (GDPR)

If you are in the EEA, UK or Switzerland, you have the right to access, correct or delete personal data we hold about you, to object to or restrict its processing, and to withdraw consent at any time. The legal bases we rely on are your consent (for advertising cookies) and our legitimate interest in running a secure, working website (for logs and cookie-free analytics). You can also complain to your local data protection authority.

California residents (CCPA/CPRA)

We do not sell personal information for money. Advertising cookies from our partners may count as “sharing” under California law. You can opt out using your browser’s Global Privacy Control signal or the opt-out links above. You have the right to know, delete and correct personal information, and we won’t discriminate against you for using these rights.

Children

Supply Math is intended for adults planning home projects. We do not knowingly collect personal information from children under 13. If you believe a child has sent us personal information, contact us and we will delete it.

Third-party links

Some pages link to other websites. We aren’t responsible for their content or privacy practices.

Changes

We’ll update this page when our practices change (for example, when we start working with an ad partner) and change the date at the top.
