4. What Fibonacci is
4.1 Fibonacci is a digital trading journal and statistical analysis tool. Features:
- dashboard with balance and results;
- profit and loss (P&L) calendar;
- analysis by session, instrument, strategy and hour;
- risk and limit tracking for personal or funded accounts;
- emotional log;
- demo backtesting;
- goals, reviews, reports and certificates.
To get your data you can:
- connect in read-only mode cTrader (official API), MetaTrader 4/5 (through MetaApi, with your investor password, which we do not store) or Interactive Brokers (Flex report);
- import history from other platforms (TradingView, TradeLocker, Match-Trader, DXtrade, NinjaTrader, Tradovate or others) or CSV/Excel files.
4.2 Fibonacci does NOT:
- execute, modify or cancel orders;
- have permission to withdraw or transfer funds;
- provide signals, recommendations or financial, investment, tax or legal advice;
- act as a broker, investment adviser or regulated entity.
4.3 Synchronization and import.
- The update frequencies we state are approximate and depend on each platform.
- Automatic column recognition and duplicate prevention work with the most common formats, but we do not guarantee that every file or broker will import without errors.
- You are responsible for checking that your data is correct.
4.4 Funded accounts. Fibonacci is not affiliated with any funding company (prop firm). The risk limits it shows are for guidance only. Your prop firm's official rules always prevail, and we are not liable for the loss of a funded account.
4.5 Certificates and reports. The certificates and reports generated by Fibonacci reflect the data recorded in your account. They are not an audit or an independent verification of results and must not be presented as such to third parties.
4.6 The statistics and data shown are for information only. Past results do not guarantee future performance. All your trading decisions are solely your own. Trading currencies, CFDs and other instruments involves a high risk of loss.
5. Third-party connections
By connecting a platform or broker, you authorize us to access that account's data in read-only mode. Those platforms are independent services with their own terms, and we are not responsible for their operation, availability or accuracy. You can revoke the connection at any time from the app or from the platform.
6. Subscription, trial and payments
6.1 Free trial: new accounts get a 7-day free trial, which requires registering a valid payment method. Only one trial per person is allowed; we may use account and payment method data to prevent repeated trials.
6.2 Plans and automatic renewal. Fibonacci offers the Trader plan (USD 50 per month or USD 540 per year) and the Mentor plan (monthly, with tiered pricing under the Mentor Annex). If you do not cancel before the trial ends, the chosen plan is charged automatically, and the subscription renews at the end of each period until you cancel it.
6.3 Automatic renewal: the subscription renews at the end of each period until you cancel it.
6.4 Cancellation: you can cancel at any time from Settings → Plan and billing, without contacting support. You will keep access until your next renewal date.
6.5 Non-refundable: all payments are final, under the Refund Policy.
6.6 Prices: prices are stated in U.S. dollars (USD) and may include applicable taxes. We will give at least 30 days' notice of any price change; you may cancel before it takes effect.
6.7 Payments are processed by Stripe. We do not store your full card details.
6.8 Promotions and Partners program. Promotions (for example, discount codes) and the Partners program are governed by their specific terms, published at fibonacciapp.com/promo and fibonacciapp.com/socios-condiciones, which form part of this Agreement. In case of conflict, those specific terms prevail for the matters they govern.
6.9 Mentor plan. The Mentor plan is also governed by the Mentor Annex, published at fibonacciapp.com/mentor-condiciones, which forms part of this Agreement. In case of conflict, the Mentor Annex prevails for the matters it governs.
7. Acceptable use
You agree not to:
- use the service for unlawful purposes;
- attempt to gain unauthorized access to other people's systems or accounts;
- reverse engineer, copy or resell the service;
- overload the infrastructure;
- share your account;
- create multiple accounts to obtain additional trials.
We may suspend or close accounts that break these rules.
7 bis. Friends
Fibonacci lets you connect with other users as friends, voluntarily share part of your results and set shared goals.
- A friendship only exists if the other person accepts your invitation. Either of you can end it at any time with "Unfriend", and the shared goals are then deleted as well.
- You decide what you share. By default you share nothing except your account name.
- The ranking and shared goals are a personal tracking tool. They are not contests or competitions with prizes, and Fibonacci does not organize, endorse or take part in bets, money challenges or agreements between friends.
- What you share with your friends is not financial advice, and you must not present it as such or use it to attract clients or investors.
- If you invite someone by email, you confirm that you know that person and that they may receive your invitation. Do not use Friends to send mass or unsolicited invitations.
- You may not copy, publish or share outside Fibonacci the data your friends share with you without their permission.
8. Intellectual property and your data
8.1 Fibonacci's software, design, trademarks and content belong to wil studio, LLC. We grant you a limited, personal, non-exclusive and non-transferable license to use them while your subscription is active.
8.2 Your trading data is yours. You grant us only the permission needed to store and process it in order to provide the service. You can export it (JSON format) and delete your account at any time from Settings → Privacy.
9. Nature of the service and reliance on third parties
Fibonacci is a digital service provided "AS IS" and "AS AVAILABLE". It relies on third-party services that we do not control, including:
- server and infrastructure providers;
- networks and security;
- payment processing;
- sign-in;
- technical monitoring;
- the platforms and brokers you connect.
These services may experience outages, changes, delays or errors at any time. As a result, Fibonacci may be affected, in whole or in part and without notice, for example through service unavailability, synchronization failures, incomplete or inaccurate data, or loss of history. You accept this risk, which is inherent to any digital service. You are responsible for keeping your own backups using the data export feature.
