Terms of service

The APX service

APX brings season tracking, historical weekends and live weekends into one intelligence suite. Engineer is a current prototype, still evolving. Features, coverage and presentation may develop over time.

APX is unofficial and is not associated with Formula 1. Data and analysis may be delayed, incomplete or inaccurate. Generated explanations and forecasts can contain errors and do not guarantee a race outcome. Use APX as an information and analysis tool.

Your account

Use an email address you control, verify it, and keep your password secure. Contact us if you suspect unauthorised access. Member access requires a verified account and an active trial or subscription; authorised administrator accounts have separate access.

Do not use APX to break the law, interfere with the service, bypass access controls, or access another person’s account. You remain responsible for respecting rights in data and content you use or share.

Trial and monthly subscription

The founding offer is S$19.99 per month after a 3-day trial, limited to the first 50 subscribers. The trial is available once per eligible account and begins when payment setup is completed, not when an account is created. Payment details are required.

At the end of your trial, your payment method is charged automatically. Your subscription then renews monthly until you cancel. The first billing date and final total are displayed in Stripe before you confirm. If you have already used your trial, payment is due when you confirm your new subscription.

Stripe securely processes payments and provides billing management. APX does not store your full card number or card security code. An unpaid or failed payment may interrupt member access until the payment is resolved.

Price changes

Your subscription renews at S$19.99 per month unless we announce a future price change. We will email you at least 30 days before a change applies to your subscription. You can cancel before the renewal at the new price.

Cancellation and refunds

Cancel through Account → Manage billing. Cancel before your trial ends to avoid the first charge. Cancellation after a paid period begins stops the next renewal, with access continuing until the end date shown in billing.

You can request a full refund within 7 days of your first subscription payment. The trial does not count as a payment. See our cancellation and refund policy for the request process and what happens to your subscription.

Signing out, uninstalling a browser app or asking to delete your account does not itself cancel a subscription. If you cannot access billing, contact us for help.

Privacy and service communications

Our privacy notice explains the information used to operate APX. We send account-security, verification, billing and other service messages needed to manage your account and subscription.

Availability and changes

APX relies on third-party data and services. We cannot promise uninterrupted availability or complete coverage for every session. We may restrict access to address misuse or protect the service. If your access is restricted while you have a paid subscription, contact us about your billing and available remedies.

We may update these terms as APX develops. Material changes will be communicated before they take effect. Price changes follow the notice period above. Nothing in these terms excludes or limits consumer rights or other rights that cannot lawfully be excluded.
