Propbook is built to be privacy-friendly. Here's exactly what we collect, why, and what we never do.
No advertising trackers, no advertising profiles, no selling your data — ever.
If you have an account, your data is stored in our database (Supabase, with row-level access rules) so it syncs across your devices. In guest mode, your journal stays only in your browser (localStorage) and is never uploaded; only the anonymous usage events above are sent.
We send account emails (confirmation, password reset) and, at most, a welcome email and one reminder if you haven't added an account yet. They are delivered by Brevo. Every non-essential email has a one-click unsubscribe link.
If you connect the official Propbook bot, we store your Telegram chat ID to send your alerts and recaps. If you use your own bot instead, you provide its token. Propbook only sends messages — it never reads your Telegram chats. Send /stop to the bot or click Disconnect in Settings to unlink.
If you connect a broker platform (for example TopstepX / ProjectX), your API key is encrypted on our server (AES-256) and used only to read your accounts and positions and to place the orders you configured in PropSync. We keep a log of every order PropSync sends or simulates so you can check what happened. Your TradingView webhook link is private to you. You can disconnect at any time.
If you choose to publish a public profile, only the anonymized stats you opt to share are made public (percentages, win rate, profit factor). No account numbers and no dollar amounts are ever published.
Supabase (database & authentication), Vercel (hosting and server functions), Brevo (emails), Telegram (alerts, if you connect it). Fonts load from Google Fonts and firm and broker logos from Google's public favicon service. When paid plans open, payments will be handled by Stripe — we never see your card details.
You can export or erase your journal anytime from Settings. Deleting your account removes your journal, sign-up answers, broker connection, PropSync setup and Telegram link. You can also ask us to access, correct or delete any other data about you, or object to the usage events, by email at propbookinc@gmail.com or through the in-app feedback button — we answer within 30 days. If you're in the EU, you may also contact your data protection authority (in France, the CNIL).
