What ERA Calculator does — and doesn't do — with your data.
The short version: the calculators run entirely in your browser. The numbers you enter are not sent to a server, stored in a database or shared with anyone.
Calculator inputs
When you change a value, the calculator may add it to the page address (for example ?er=12&ip=36.0) so you can bookmark or share the result. That address stays in your browser unless you choose to share it. It contains only the pitching numbers you typed.
Accounts and cookies
There are no accounts, and the site doesn't set cookies of its own.
Hosting
Like any website, the hosting provider that serves these pages may keep standard technical logs (such as IP address, browser type and the page requested) to operate and secure the service.
Changes
If this policy changes — for example, if analytics are added — this page will be updated first.
