What we collect
Freeze Dry Math has no accounts and no forms. The calculators run entirely in your browser; the numbers you type are not sent to us. If you use the Share button, your inputs are put in the page link so the recipient sees the same result.
Our host (Cloudflare) keeps standard server logs, such as IP address and pages requested, for security and reliability.
