Terms

Last updated 28 October 2026. Fuller terms will replace these after legal review.

These terms are between you and Magnum Opus. By creating an account or using Magnum Opus you agree to them.

Personal license. Your account is for you alone, 18 or older, on up to two computers. Don’t share, copy or resell the app or your access, or get around its limits.
Plans and AI limits. Each plan includes a weekly number of prompts and a fair-use limit, shown on the pricing page and in the app. We may suspend an account that’s shared or abused.
Your data. You own your journal. It stays on your computer, also if you cancel; keep backups (Settings → Your data).
Read-only. The app never places, changes or cancels orders.
Not financial advice. Nothing in Magnum Opus, including the AI, is financial or trading advice. The AI can be wrong. Recaps and reviews are hindsight. Trading futures carries a substantial risk of loss; every trade is your decision.
Your broker and firm. You’re responsible for following your broker’s and prop firm’s terms. Challenge rules in the app are presets; your firm’s own rules are what count.
Changes. We may change features. We’ll tell you at least 15 days before a change to these terms that matters, and you can cancel before it applies.
As is. Magnum Opus is provided as is. To the extent the law allows, we aren’t liable for trading losses or indirect damages, and our total liability is limited to what you paid us in the last 12 months. Your rights as a consumer aren’t affected.
