1. Acceptance of Terms

These Terms of Service ("Terms") constitute a legally binding agreement between you ("User", "you", or "your") and BDPO Ltd, a company registered in England and Wales under company number 13314687, with its registered office at 60 Tottenham Court Road, Suite 5994a, Fitzrovia, London, W1T 2EW, United Kingdom ("Company", "we", "us", or "our"). These Terms govern your access to and use of BDPO and all related services, applications, tools, and features (collectively, the "Services").

By creating an account, accessing, or using our Services in any way, you represent and warrant that:

• You are at least 18 years of age and have the legal capacity to enter into this agreement
• You have read, understood, and agree to be bound by these Terms
• You have read, understood, and agree to our Privacy Policy
• You are not prohibited from using our Services under applicable laws
• You accept full responsibility for all activities conducted through your account

2. Description of Services

BDPO provides a browser-based backtesting platform for simulating trading strategies using historical market data. The Services allow users to create, test, and analyze trading strategies through both coded and codeless interfaces.

The Services also include tools for exploring and visualizing data aggregated from third-party and public sources, including institutional ownership and regulatory filing data (such as data derived from SEC Form 13F filings), portfolio concentration metrics, filing histories, and similar information. All such data is presented purely as information and data. We do not originate, audit, verify, endorse, or vouch for this data, and we do not present it as a recommendation, signal, or advice of any kind.

THE SERVICES ARE PROVIDED FOR EDUCATIONAL AND INFORMATIONAL PURPOSES ONLY. The backtesting results, analytics, institutional and third-party data, metrics, rankings, lists, and any other information provided through our Services are simulations or aggregated data and do not represent actual or recommended trading results, do not constitute advice, and do not guarantee future performance.

4. Risk Acknowledgment

By using our Services, you expressly acknowledge and agree that:

• Trading and investing in financial markets involves substantial risk of loss
• You may lose some or all of your invested capital
• Backtesting results do not guarantee future performance
• Historical data may contain errors, gaps, or inaccuracies
• Market conditions change and past patterns may not repeat
• Slippage, commissions, taxes, and other factors may significantly impact real trading results
• You are solely responsible for evaluating the risks and merits of any trading decision
• You have the financial resources to bear any losses that may result from trading
• You will not rely solely on our Services when making trading or investment decisions

4.1 Backtesting and Simulation Limitations

The backtesting and optimization engine is software, and like all software it may contain bugs, defects, or design limitations. You expressly acknowledge and agree that:

• The simulation engine, our data processing pipelines, and any metrics, statistics, or analytics we compute may contain errors and may produce results that are incorrect, incomplete, or misleading
• The engine necessarily makes simplifying assumptions — including about order execution, fill prices, slippage, commissions and fees, liquidity, market impact, dividends, corporate actions, taxes, and the timing and availability of data — and its behaviour may differ materially from how the same strategy would behave in live markets
• Backtested results may suffer from survivorship bias, look-ahead bias, overfitting (particularly where strategies are optimized against historical data), and other methodological limitations
• Results may change between versions of the Services as we modify the engine, data sources, or methodology, and may not be reproducible
• A strategy that performs well in simulation may perform poorly, or lose money, when traded with real capital, and no simulated result should be treated as an indication of how a strategy will actually perform

We make no representation or warranty that the backtesting engine operates correctly, that its methodology is suitable for any purpose, or that simulated results bear any relationship to results that could be achieved in real trading.

5. User Accounts and Responsibilities

To access certain features, you must create an account. You agree to:

• Provide accurate, current, and complete information
• Maintain the security of your account credentials
• Promptly notify us of any unauthorized access
• Accept responsibility for all activities under your account
• Not share your account with others
• Not create multiple accounts or use false identities

6. Prohibited Uses

You agree not to:

• Use the Services for any illegal purpose or in violation of any laws
• Attempt to gain unauthorized access to our systems or other users' accounts
• Interfere with or disrupt the Services or servers
• Transmit viruses, malware, or other harmful code
• Scrape, harvest, or collect data from the Services without permission
• Reverse engineer, decompile, or disassemble any part of the Services
• Use the Services to provide services to third parties without authorization
• Circumvent any access controls or usage limits
• Misrepresent your identity or affiliation
• Use the Services in any way that could damage our reputation

7. Intellectual Property

All content, features, and functionality of the Services, including but not limited to software, code, algorithms, text, graphics, logos, and trademarks, are owned by BDPO Ltd or its licensors and are protected by intellectual property laws.

You retain ownership of strategies, code, and content you create using our Services, but you grant us a non-exclusive, royalty-free, worldwide license to use, store, and process such content as necessary to provide the Services.

8. Data and Accuracy

WE MAKE NO WARRANTIES OR REPRESENTATIONS REGARDING THE ACCURACY, COMPLETENESS, TIMELINESS, OR RELIABILITY OF ANY DATA, INFORMATION, OR CONTENT PROVIDED THROUGH OUR SERVICES. Historical market data, prices, indicators, calculations, and institutional, ownership, regulatory filing, and other third-party data (including data derived from SEC Form 13F filings) may contain errors, omissions, misclassifications, gaps, or inaccuracies, and may be delayed, out of date, or incomplete. A significant portion of the data made available through the Services is sourced from third parties and public filings that we do not control and have not independently verified. You acknowledge that:

• All data is provided "as is" and "as available" without any warranty of any kind
• We do not originate, audit, or verify third-party or institutional data and are not responsible for any errors, omissions, or delays in it
• We are not responsible for any errors in data, metrics, or calculations
• Our own ingestion, transformation, aggregation, and calculation processes may themselves introduce errors into the data and figures displayed, even where the underlying source data is accurate
• Regulatory filing data (such as 13F data) is inherently backward-looking, is reported with a delay, and may exclude positions, instruments, or holdings that are not required to be reported
• You must not rely on any data provided through the Services and should independently verify it against original sources before making any decision
• Data sources may have limitations, gaps, or biases

9. Local Resource Usage and Data Persistence

The Services may perform computations and store certain information using a combination of client-side (on-device) processing and server-side storage. You acknowledge and agree to the following:

9.1 Client-Side Processing

The Service utilizes a decentralized, client-side architecture to perform computations. By initiating a backtest or strategy simulation, you acknowledge and agree that the Service may utilize your device’s local processing power (CPU), memory (RAM), and battery life. Complex simulations (including high-frequency or high-resolution backtests) may result in significant system resource consumption, which could temporarily affect the performance of other applications on your device or increase device temperature.

9.2 Local Storage and Caching (Browser Storage)

To optimize performance and improve your experience, we may store certain data locally on your device using browser-based storage technologies (such as IndexedDB and localStorage). This may include cached historical candle data, charting state, UI preferences, and other non-sensitive application data.

Locally stored data is intended to improve performance and convenience. Unless explicitly stated in the product (for example, where you choose to save, sync, or export), this local cache is not intended to be a reliable backup.

9.3 Volatility of Local Data

You understand that data stored via local browser technologies is volatile. Your cached backtest history, simulation results, or other locally stored information may be permanently lost or inaccessible if:

• You clear your browser’s cache, cookies, or site data
• Your device runs low on available disk space (triggering automatic browser cleanup)
• You access the Service from a different browser or a different device
• You use “Private”, “Incognito”, or “Guest” browsing modes

9.4 Limitation of Liability for Local Data Loss

BDPO Ltd is not responsible for any loss of simulation data, trade history, or strategy performance metrics resulting from local storage failures, browser settings, device limitations, or user-initiated data clearing. Where export or download functionality is provided, we strongly recommend exporting critical result summaries promptly after simulation.

9.5 Server-Side Storage and Syncing

To provide core functionality and a better user experience (including access across devices, account continuity, and product improvements), we may store certain information on our servers when you use the Services. This may include:

• Account information and authentication/session data
• Saved strategies and configurations (coded and codeless)
• Backtest runs and related performance statistics/metrics (where you run or save them under your account)
• Subscription/billing status and related metadata (if applicable)
• Product settings and preferences (e.g., editor settings) associated with your account

Server-side storage is subject to our Privacy Policy and applicable law. We do not guarantee that stored results will be available indefinitely and may impose retention limits, quotas, or plan-based limits.

10. Payment Terms

Certain features require a paid subscription. By subscribing, you agree to:

• Pay all applicable fees as described at time of purchase
• Provide accurate payment information
• Authorize recurring charges for subscription services
• Accept that, except for the cancellation rights described below and any other rights you have under applicable law, fees are non-refundable

We reserve the right to modify pricing at any time. Price changes will apply to subsequent billing periods after notice is provided.

10.1 Consumer Cancellation Rights (Cooling-Off Period)

If you are a consumer in the United Kingdom (or another jurisdiction granting equivalent rights), you may have a statutory right to cancel a purchase within 14 days of entering into the contract under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013, without giving a reason. To exercise this right, contact us at [email protected] within the 14-day period.

Because the Services provide access to digital content and services immediately on purchase, you acknowledge and expressly request that we begin providing the Services during the cancellation period. You understand that: (a) once a service has been fully performed you lose the right to cancel; and (b) where you receive digital content during the cancellation period, you consent to that supply and acknowledge that you thereby lose your statutory right to cancel in respect of that content. Where you cancel within the period and the Services have only been partially performed, you may be charged a proportionate amount for what has been supplied.

14. Dispute Resolution and Arbitration

PLEASE READ THIS SECTION CAREFULLY. IT AFFECTS YOUR LEGAL RIGHTS.

Informal resolution first. Before commencing any formal proceedings, you agree to first contact us at [email protected] and attempt in good faith to resolve the dispute informally. Most concerns can be resolved this way.

14.1 If you are a consumer

If you use the Services as a consumer (rather than in the course of a business, trade, or profession), nothing in these Terms requires you to submit to binding arbitration, and the class-action waiver in section 14.2 does not apply to you. You retain the right to bring proceedings in the courts identified in the Governing Law section below, to access any applicable alternative dispute resolution or ombudsman scheme, and to rely on the mandatory consumer-protection laws of your country of residence. Nothing in this section limits your statutory rights.

14.2 If you are a business user

If you use the Services in the course of a business, trade, or profession, any dispute, controversy, or claim arising out of or relating to these Terms or the Services that is not resolved informally shall be resolved through binding arbitration administered in accordance with the rules of the London Court of International Arbitration (LCIA). The seat of arbitration shall be London, England, and the language of arbitration shall be English. The arbitrator's award shall be final and binding, and judgment upon the award may be entered in any court of competent jurisdiction.

Class-action waiver (business users only). Where you are a business user, all claims must be brought in your individual or corporate capacity and not as a plaintiff or class member in any purported class, collective, or representative proceeding.

15. Governing Law and Jurisdiction

These Terms shall be governed by and construed in accordance with the laws of England and Wales, without regard to conflict of law principles. Subject to the dispute resolution provisions above, any legal action or proceeding arising under these Terms shall be brought exclusively in the courts of England and Wales, and you hereby consent to the personal jurisdiction and venue therein.

If you are a consumer, this section does not deprive you of the protection afforded by the mandatory laws of your country of residence, and you may also bring proceedings in the courts of that country. If you are a consumer resident in Scotland or Northern Ireland, you may bring proceedings in your local courts under the law of that jurisdiction.

16. Termination

We may suspend or terminate your access to the Services at any time, with or without cause or notice, for any reason including but not limited to violation of these Terms. Upon termination:

• Your right to use the Services immediately ceases
• You remain bound by provisions that by their nature survive termination
• We may delete your account and associated data
• We have no obligation to provide refunds

17. Modifications to Terms

We reserve the right to modify these Terms at any time. Changes will be effective upon posting to the website with an updated effective date. Where a change is material and you hold an account or an active subscription, we will give you reasonable advance notice (for example by email or an in-product notice) before the change takes effect, and you may stop using the Services or cancel your subscription before it does. Your continued use of the Services after any modifications constitutes your acceptance of the revised Terms. If you do not agree to the modified Terms, you must stop using the Services.

18. Modifications to Services

We reserve the right to modify, suspend, or discontinue the Services or any part thereof at any time, with or without notice, for any reason. We shall not be liable to you or any third party for any modification, suspension, or discontinuation of the Services.

19. Force Majeure

We shall not be liable for any failure or delay in performing our obligations where such failure or delay results from circumstances beyond our reasonable control, including but not limited to acts of God, natural disasters, war, terrorism, riots, embargoes, acts of civil or military authorities, fire, floods, accidents, pandemic, strikes, or shortages of transportation, facilities, fuel, energy, labor, or materials.

20. Severability

If any provision of these Terms is held to be invalid, illegal, or unenforceable, the remaining provisions shall continue in full force and effect. The invalid provision shall be modified to the minimum extent necessary to make it valid and enforceable while preserving the parties' original intent.

21. Waiver

Our failure to enforce any right or provision of these Terms shall not constitute a waiver of such right or provision. Any waiver must be in writing and signed by an authorized representative of BDPO Ltd.

22. Assignment

You may not assign or transfer these Terms or your rights hereunder without our prior written consent. We may assign these Terms without restriction. Any attempted assignment in violation of this section shall be null and void.

23. Entire Agreement

These Terms, together with our Privacy Policy and any other agreements expressly incorporated by reference, constitute the entire agreement between you and BDPO Ltd regarding the Services and supersede all prior and contemporaneous agreements, representations, and understandings.

24. No Third-Party Beneficiaries

These Terms are for the benefit of BDPO Ltd and you only and are not intended to confer any rights or benefits on any third party, except that the Protected Parties are third-party beneficiaries of the limitation of liability and indemnification provisions.
