What we collect
Nothing. Aperture Math has no account, no form, no newsletter, no comments, no analytics and no advertising. The calculators run entirely in your browser: the figures you enter are not sent or stored. Aperture Math sets no cookies. Fonts are served from our own host, not from a third party.
Third parties
Our host, Cloudflare, processes technical data needed to deliver the pages (such as IP addresses) under its own privacy policy. When you click a link to a store, you leave Aperture Math: the store, and its affiliate network if a program accepts us later, may set cookies to attribute a purchase to our site, under their own privacy policies.
Do Not Track and California
Because we collect no personally identifiable information, there is nothing to share and Do Not Track signals change nothing on Aperture Math. This policy is written with the California Online Privacy Protection Act (CalOPPA) in mind. If this ever changes, we will update this page and its effective date first.
