Privacy policy
HandyWren has no accounts and no database. The calculators run in your browser, and the numbers you type are never sent to a server.
What stays on your device
When you save a scenario (A, B or C) under "Compare scenarios", your browser keeps it in its local storage on your device. It is not sent anywhere. To delete a scenario, press Clear next to it. To delete everything, clear the site data for handywren.com in your browser settings.
A share link puts your inputs after the # in the address. Browsers don't send that part to the server, so only the people you send the link to can see those numbers.
Hosting
Cloudflare hosts this site. Like any web host, Cloudflare may log standard request data, such as your IP address, browser type, the page you asked for and the time, to deliver the site and protect it from abuse. Its privacy policy explains how it handles that data.
Analytics
HandyWren doesn't use analytics or tracking scripts. If that changes, this policy will change first.
