Refunds & Billing Policy

Last updated: September 13, 2026

Toptier Aero is operated by First Principles Foundry LLC.

Subscription fees

Some features require a paid subscription. Fees are billed in advance on a recurring monthly basis until canceled. All amounts are in U.S. dollars and do not include taxes, which may be added where required.

Billing

Payments are processed by our third-party payment provider. By subscribing, you authorize us to charge the payment method on file each billing cycle. If a payment fails, we may retry the charge and may suspend or downgrade your access until payment is successfully processed.

Cancellation

You may cancel your subscription at any time through the Settings page or by contacting support. Cancellation takes effect at the end of your current billing period, and you will retain access until that date.

Refunds

All subscription charges are non-refundable except where required by applicable law or at our sole discretion. Promotional or trial subscriptions convert to paid subscriptions unless canceled before the trial ends.

If you believe you were charged in error or you are entitled to a refund under applicable law, contact us at support@toptieraero.com within 30 days of the charge. We review each request individually and will issue a refund where appropriate.

Price changes

We may change subscription prices or introduce new fees with reasonable notice before the change applies to your next billing cycle. Continued use after the new price takes effect constitutes acceptance of the updated fee.

Chargebacks and disputes

If you initiate a chargeback or payment dispute without first contacting us, we reserve the right to suspend your account pending resolution. We encourage you to reach out to support for any billing concerns before disputing a charge.
