Echelon by d1 · effective September 15, 2026

Echelon is a trading education product: the training, session recaps, and the member chat, on the web at d1fpc3.com, in the Windows desktop app, and in the iOS app. This page says what we store and why, in plain language.

What we collect

• Your account. Email address, and a password if you set one. Sign-in also works through a link we email you, or through Discord if you connect it.
• Your profile. The username, photo, and bio you choose to add.
• What you write in Echelon. Chat messages, journal pages, trade recaps and their charts, homework submissions, and reviews. Your journal is private to you; chat and posted recaps are visible to other members.
• Progress. Which lessons and videos you have opened, so the app can hold your place.
• Purchases. Payments run through Stripe on the web and through Apple In-App Purchase in the iOS app. We keep the record of what your account owns, including the TradingView username you give us for the D1 GEX indicator; card details never touch our servers, and Apple shares none with us.
• Discord, if you connect it. Your Discord account id and username, used to place you in the member server with the right role. Disconnecting removes the link.

What we do not do

• No ads, and no selling or sharing of your data with anyone.
• No tracking in the apps.
• No reading of your private journal. It is yours.

Where it lives

Data is stored with Supabase (our database and authentication provider). Payments are processed by Stripe on the web and by Apple in the iOS app. All of them act on our instructions to run Echelon and nothing else.

Deleting your account

Settings, then Delete account, inside the app. It removes your account and everything attached to it. You can also email d1fpc3@gmail.com and we will do it for you.
