By accessing or using the Site or Services, you agree to these Terms. If you do not agree, do not use the Site or Services.

2. Definitions

• “Content” means all materials made available on or through the Services, including articles, operating notes, technical documentation, commentary, graphics, reports, and archives.
• “Journal” means the AI Trading Systems Lab Journal and any associated archive or publication area within the Services.
• “Subscriber” means a user with an active paid subscription (or other approved access) to the Journal.
• “You” means the individual accessing the Services, and/or the entity on whose behalf you are acting.

3. Nature of the Services

3.1 Educational and research-focused content

The Services provide access to an electronic journal and archive of experience-based operating notes and publications, including (by way of example):

• professional articles and operating notes on live system behaviour,
• technical and operational documentation,
• analytical commentary on stability, observability, incident handling, and governance,
• system design and governance discussions.

Content is provided for informational, educational, and research purposes.

3.2 No client asset management; proprietary trading only

Bifin conducts autonomous systems research and engages in proprietary trading using its own capital. We do not manage client assets, do not accept trading instructions, and do not provide brokerage services to users.

3.3 Not investment advice or a solicitation

Nothing on the Site or within the Services constitutes, or should be relied upon as:

• investment advice,
• financial advice,
• trading recommendations,
• an offer or solicitation to buy or sell any financial instrument, or
• portfolio management services.

Bifin does not provide personalized advice and does not consider your circumstances, objectives, or risk tolerance.

3.4 Market and trading references

The Services may reference Bifin’s research into or use of public information, including corporate news and announcements, press released, statutory and regulatory corporate filings (such as made available through the U.S. Securities and Exchange Commission), publicly disclosed financial statments and markets where securities are listed (including the New York Stock Exchange and Nasdaq). Such references are descriptive and informational.

Past performance, historical results, or examples (if any) do not guarantee future results.

4. Eligibility, professional use, and account approval

4.1 Professional / business use

The Services are intended for professional, institutional, and business use. They are not designed for retail users.

By subscribing or using subscriber-only areas, you represent that you are using the Services in a professional or business capacity, and (if applicable) that you have authority to bind your employer or the entity you represent.

4.2 Manual approval

Access to the Journal is subject to review and manual approval by Bifin. We may request information reasonably necessary to assess eligibility and may grant or deny access at our discretion.

4.3 Age and capacity

You must be at least 18 years old and have legal capacity to enter into these Terms.

5. Accounts and access security

• You are responsible for maintaining the confidentiality of your login credentials and for all activity under your account.
• You must provide accurate and complete information and keep it up to date.
• You must promptly notify us if you suspect unauthorized access to your account.

We may implement measures to detect unusual activity and protect the Services (including rate limits, session controls, and access restrictions).

6. Subscriptions, billing, taxes, cancellation, and refunds

6.1 Subscription fees

Unless otherwise stated in writing by Bifin, Journal access is offered on a recurring subscription at €149 per month, plus applicable taxes (including VAT where required).

6.2 Taxes (including VAT)

Taxes are applied in accordance with applicable law and may depend on factors such as your location and status (e.g., whether you provide a valid VAT identification number where relevant). You are responsible for any taxes applicable to your purchase except taxes based on Bifin’s income.

6.3 Payment processing and onboarding providers

Subscription onboarding and account access are provided through Memberstack. Payments are processed by Stripe.

Your use of those services may also be subject to their respective terms and policies. Bifin is not responsible for interruptions, errors, or outages caused by third-party providers.

6.4 Billing cycle and renewal

Subscriptions are billed on a recurring monthly basis unless cancelled before renewal. You authorize recurring charges until cancellation.

If a payment fails or is reversed, we may suspend or terminate access until payment is successfully made. You remain responsible for all amounts due.

6.5 Access review and refunds if access is not granted

Subscription payment may be required before access is reviewed and activated.

If, after review, we decide not to grant you access, we will refund the subscription payment for that period. This refund mechanism applies to denial of access following review and is separate from voluntary cancellation.

6.6 Cancellation

You may cancel your subscription at any time. Cancellation takes effect at the end of the current billing period. You will retain access until the end of that period unless your access is suspended or terminated under these Terms.

6.7 Refunds for voluntary cancellation

Except where required by mandatory law, no refunds are provided for partial billing periods or unused time following voluntary cancellation.

6.8 Fee changes

We may change subscription fees or pricing models from time to time. Changes apply prospectively and, where feasible, will take effect at renewal. If you do not agree to a fee change, you must cancel before the new fee takes effect.

7. Acceptable use

You agree not to, and not to allow others to:

1. copy, reproduce, distribute, sell, sublicense, publish, or publicly display Content (except as expressly permitted by these Terms);
2. share account credentials, provide access to non-authorized persons, or use the Services on a bureau service/time-sharing basis;
3. remove or obscure proprietary notices, trademarks, or disclaimers within the Content;
4. scrape, crawl, spider, harvest, or use automated means to access the Services except as permitted by us in writing;
5. attempt to reverse engineer, decompile, disassemble, or otherwise derive source code or underlying ideas from the Services or Content, except to the extent such restriction is prohibited by law;
6. use Content to build, train, fine-tune, or improve any machine learning or AI model, or to create or support a competing product or service, unless Bifin expressly authorizes this in writing;
7. interfere with or disrupt the Services, security features, or access controls, or attempt to bypass paywalls or authorization mechanisms;
8. use the Services in any unlawful, deceptive, or misleading manner, including in violation of securities laws or regulations applicable to you;
9. use the Services in a way that could expose Bifin to legal or regulatory risk.

We may investigate violations and suspend or terminate access as described in Section 13.

8. Intellectual property and license

8.1 Ownership

All Content and Services (including text, documentation, design elements, and compilations), and all associated intellectual property rights, are owned by Bifin or its licensors and are protected by applicable laws.

8.2 Limited license

Subject to your compliance with these Terms and payment of applicable fees, Bifin grants you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to access and use the Services and Content solely for your internal professional purposes.

No rights are granted except as expressly stated in these Terms.

8.3 Feedback

If you provide suggestions, ideas, or feedback, you grant Bifin a perpetual, worldwide, royalty-free right to use, modify, and incorporate that feedback without restriction or compensation.

9. Confidentiality of subscriber-only materials

Subscriber-only Content (including the Journal archive and any materials behind a paywall) is proprietary to Bifin and made available on a limited-access basis.

You must treat subscriber-only Content as confidential and must not disclose it to any third party, except to the extent necessary for internal use within your organization by authorized personnel, and only where such sharing is consistent with the subscription you purchased and access controls in place.

Unauthorized disclosure may cause irreparable harm. Bifin may seek injunctive or equitable relief in addition to any other remedies available.

10. Third-party materials and links

The Services may reference or include third-party materials (e.g., public disclosures, research, reports, or other content). Such materials remain the property of their respective owners.

Links to third-party sites are provided for convenience. Bifin does not control and is not responsible for third-party sites, content, products, or services.

11. Availability; changes to the Services

We may modify, update, suspend, or discontinue any part of the Services at any time, including Content, features, or availability. We do not guarantee that the Services will be uninterrupted, timely, secure, or error-free.

We may also impose limits on use (for example, to protect system integrity) and may restrict access to certain parts of the Services at our discretion.

12. Disclaimers

12.1 “As is” and “as available”

To the maximum extent permitted by law, the Services and Content are provided “as is” and “as available”, without warranties of any kind, whether express, implied, or statutory, including implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement.

12.2 No reliance

You are responsible for evaluating the accuracy, completeness, and usefulness of any Content. You should not rely on Content as a substitute for professional advice.

13. Limitation of liability

To the maximum extent permitted by law:

1. Bifin will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of profits, revenue, business, goodwill, opportunities, or data, arising out of or related to the Services or these Terms, even if foreseeable or if we have been advised of the possibility of such damages.
2. Bifin will not be liable for losses arising from trading, investment decisions, or reliance on Content.
3. Bifin’s total liability for all claims arising out of or related to the Services or these Terms will not exceed the total subscription fees paid by you to Bifin for the Services in the three (3) months immediately preceding the event giving rise to the claim.

Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law (including liability for fraud, wilful misconduct, or certain categories of gross negligence where limitation is prohibited).

14. Indemnification

You agree to indemnify and hold harmless Bifin, its directors, officers, employees, and agents from and against any claims, damages, liabilities, costs, and expenses (including reasonable legal fees) arising out of or related to:

• your access to or use of the Services,
• your breach of these Terms, or
• your violation of any applicable law or third-party rights.

15. Suspension and termination

15.1 Suspension/termination by Bifin

We may suspend or terminate your access to the Services (in whole or in part) immediately if we reasonably believe that:

• you have violated these Terms,
• your use poses a security risk, could disrupt the Services, or could expose Bifin to liability, or
• we are required to do so by law or a lawful request.

15.2 Termination by you

You may terminate by cancelling your subscription as described in Section 6.6.

15.3 Effect of termination

Upon termination, your right to access and use the Services ends immediately (except where we allow continued access until the end of a paid term, unless terminated for cause). Sections that by their nature should survive termination will survive, including Sections 8–10 and 12–18.

Termination does not affect any payment obligations accrued before termination.

16. Privacy

Our processing of personal data is described in our Privacy Policy, which forms part of the contractual framework for your use of the Services.

17. Changes to these Terms

We may update these Terms from time to time. The “Last updated” date indicates when they were most recently revised. Continued use of the Services after changes become effective constitutes acceptance of the updated Terms.

18. Miscellaneous

18.1 Entire agreement

These Terms constitute the entire agreement between you and Bifin regarding the Services and supersede prior or contemporaneous communications on the same subject.

18.2 Severability

If any provision is held invalid or unenforceable, the remaining provisions remain in full force and effect.

18.3 No waiver

Failure to enforce any provision is not a waiver of that provision.

18.4 Assignment

You may not assign or transfer these Terms without Bifin’s prior written consent. Bifin may assign these Terms in connection with a merger, acquisition, corporate reorganization, or sale of assets.

18.5 Force majeure

Bifin is not responsible for delays or failures caused by events beyond its reasonable control.

18.6 Language

These Terms are drafted in English. If a translation is made available, the English version will prevail to the extent permitted by law.
