Account
Create an account.
Free, and it opens the whole site — the research, every data series and the tools. You will get one email to confirm the address; the account does not work until you follow it.
What an account holds
Your email address, your password (hashed — it is never stored in a readable form and cannot be recovered, only replaced), when you signed up, and which tier you are on. Nothing else. No portfolio data of any kind is stored on this site: that lives in a separate system behind its own login, and the separation is structural rather than a matter of policy.
