We collect the minimum we need and document everything we do with it.
When you register, we store your email address and a hashed password. If you fill in profile fields (display name, phone), we store those. When you save scenarios, watchlists, or holdings, we store the inputs you entered.
Your data powers the features you use: saved scenarios reload your inputs, watchlists notify you when rates move, and the workstation values your holdings against current market data. We never use your data to target advertising and we do not run third-party trackers on this site.
