Does my data save automatically?

When you're signed in, the tools save your inputs to your DDH account automatically. That means:

• Your numbers are there when you come back — on your laptop, phone, or tablet.
• You can use a tool today and finish it next week without re-entering anything.

If you're using a tool without signing in (for example on a public tool page), your data lives only in that browser session and isn't saved to an account. Sign in first to keep your work.
