This app stores data in your browser's local storage — a small area of space on your computer, managed by your web browser.
Private to you. The data lives only on this device and browser. Nobody else can see it — not other users, not the site owner, not us.
Not uploaded anywhere. Nothing is sent to a server. If you use a different browser or device, you won't see the same data.
Not backed up. If you clear your browser data, switch browsers, or use a different device, your data will be gone. There is no way to recover it.
You can delete it anytime. Clear your browser data or use your browser's developer tools to remove it. It will also be cleared if you clear cookies/site data.
