What we collect
Nothing you type. The percentage calculator runs entirely in your browser; the numbers you enter are never transmitted to, logged by, or stored on any server.
Accounts
There are no accounts, sign-ups, or logins, so we hold no names, email addresses, or passwords.
Cookies and storage
The calculator sets no advertising or tracking cookies. Standard server request logs may be kept by our hosting provider for security and reliability, and can include IP address and browser user-agent.
Third parties
No ads, no affiliate links, and no data is sold or shared. Downloads are generated locally in your browser.
