Please read these Terms of Service carefully before using the EFISCharts website or subscribing to any EFISCharts service. By accessing our website or purchasing a subscription, you agree to be bound by these Terms. If you do not agree, do not use our Services.

Aviation Safety Notice. Charts and data provided through EFISCharts are intended as supplemental situational awareness tools only. They are not certified for primary navigation and are not a substitute for official aeronautical charts, publications, or preflight planning. The Pilot in Command is solely responsible for all flight decisions. Always verify chart currency and accuracy through official FAA sources before flight.

Billing. Annual subscriptions are billed in advance for each subscription year. Payment is processed through our third-party payment processor. By providing payment information, you authorize us to charge the applicable subscription fee.

Auto-Renewal. Subscriptions automatically renew at the end of each subscription year at the then-current rate unless you cancel before the renewal date. We will notify you before any price changes take effect.

Cancellation. You may cancel your subscription at any time through your account or by contacting us. Cancellation takes effect at the end of your current paid period. We do not offer prorated refunds for partial subscription periods, except where required by applicable law.

Refunds. If you are dissatisfied with the Services within the first 30 days of a paid subscription (not a trial), contact us and we will evaluate your request in good faith. We reserve the right to decline refund requests after 30 days.

Price Changes. We reserve the right to adjust subscription pricing. We will provide at least 30 days' notice of any price increase before your next renewal date.
