Terms, Privacy & Safeguarding

1. Terms & Conditions of Engagement

By booking a diagnostic consultation, executing an advisory track, or submitting payment for services, you (the "Client") enter into a legally binding contract with Darren Brumby trading as Mathentica (the "Coach"). If the student receiving coaching is under the age of 18, the parent or legal guardian executes this contract on their behalf and accepts full financial responsibility.

1.1 Automated Stripe Payment Architecture

• To secure an elite coaching placement, Clients agree to the fees published on the Mathentica platform (£150 per individual session or £450 per strategic block of 3) and must maintain a valid, authorized payment method securely on file within our integrated Stripe payment gateway.
• Pre-Session Settlement: Individual sessions are automatically billed and processed via Stripe forty-eight (48) hours prior to the scheduled session start time. Access to the live interactive BitPaper canvas and audio array is strictly contingent upon successful payment authorization.
• If an automated transaction fails, the Client will receive an immediate automated alert to update their billing credentials. If payment is not successfully settled twenty-four (24) hours before the session, the slot will be automatically cancelled and reallocated to waitlisted candidates.
• For multi-session strategic blocks purchased via direct Stripe payment links, full payment must clear prior to the scheduling of the initial diagnostic or coaching window.

1.2 Strict 24-Hour Cancellation & No-Show Policy

• The Coach operates an absolute and unyielding 24-hour notice policy for all session cancellations or rescheduling requests.
• Because your specific calendar slot is reserved exclusively for the student, cancellations or requests to reschedule made **less than 24 hours** prior to the scheduled session start time will result in the session fee being forfeited in full. The payment captured via Stripe will be retained as a late-cancellation fee.
• Cancellations made with more than 24 hours' notice will not incur a charge, and any pre-authorized funds for that specific slot will be released or credited toward a rescheduled date within the same academic term.

1.3 Liability Limitation & No Guarantee of Academic Outcomes

• The pedagogical coaching provided by the Coach is designed to significantly improve conceptual mastery, cognitive resilience, and advanced analytical execution. However, academic performance is ultimately contingent upon the student’s independent work ethic, psychological state on examination days, and variable institutional grade thresholds.
• The Coach offers no warranties or absolute legal guarantees regarding specific examination grades (e.g., A*), marks, university admission offers, or placement outcomes at Oxford, Cambridge, or Russell Group institutions.
• To the maximum extent permitted by English law, the total liability of Darren Brumby for any claim arising out of or in connection with these services is limited strictly to the total fees paid by the Client to the Coach during the specific calendar month in which the dispute occurs.

1.4 Intellectual Property & Digital Canvas Rights

• All pedagogical assets, custom STEP matrices, proof derivations, notes, and curriculum structures generated during live sessions on the BitPaper canvas ecosystem remain the intellectual property of the Coach.
• The student is granted an exclusive, non-transferable, lifelong license to review these materials for personal educational revision.
• Under no circumstances may the Client copy, resell, publicly publish, upload to public web frameworks, or distribute these digital whiteboards to third parties.

2. Privacy & Data Protection Policy (UK GDPR)

This section sets out how your personal data is collected, securely managed, and processed in full compliance with the UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018.

2.3 Data Storage & Secure Retainers

2.5 Statutory Rights of the Data Subject

Under UK law, you have the right to request access to the personal data held about you, request the rectification of inaccuracies, or request data restriction or deletion (where it does not conflict with legal tax or insurance retention requirements). To execute these rights, submit a direct request to Darren Brumby via the website contact portal.

3. Online Safeguarding & Child Protection

As a senior academic professional, Fellow of the Chartered College of Teaching (FCCT), and veteran educator with decades of institutional leadership, the Coach maintains an unyielding commitment to the highest standards of online safety and safeguarding.

3.1 Professional Verifications

• The Coach maintains a current, fully verified Enhanced Disclosure and Barring Service (DBS) Certification.
• Evidence of certification validity can be shared securely with parents or legal guardians upon request prior to the commencement of the first diagnostic session.

3.2 Operational Protocols for Online Interaction

• All live audio, visual, and written canvas interactions are managed strictly inside professional, invite-only digital workspaces (e.g., secure BitPaper canvas links combined with high-definition audio arrays).
• The Coach will never request or engage in informal communications with minor students via personal social media channels, SMS, or unmapped chat protocols. All out-of-session communications regarding logistics, work submission, or scheduling must flow through the parent's registered email or authorized contact number.
• Parents retain a standing, unrestricted open invitation to sit in on or audit any live coaching session from the student's physical location.
