Your Account
An account is optional. It exists for one purpose: saving your decision cases so you can continue on another device. Calculators and the decision workflow work fully without one.
Accounts are not enabled right now. All tools remain available without one.

Saved decision cases

Free accounts store one decision case. Saving again overwrites the stored copy.
Your data
Stored for your account: your email address and the decision cases you explicitly saved (titles, scenario numbers, assumptions). Nothing is stored unless you press Save. Data lives in the EU (Stockholm region). Analytics never receive case contents.
