Can I cancel at any time?
Yes. You can cancel before your next renewal and continue using Premium until the end of your current billing period.
Is there a money-back guarantee?
Premium includes a 14-day money-back guarantee. Contact CertiLang within 14 days of purchase if the platform is not right for you.
