Please read these terms carefully before using PrepLion. By using the platform, you agree to the terms described below.
By accessing or using PrepLion (preplion.ai), you agree to be bound by these Terms of Service. If you do not agree to these terms, please do not use the platform. We may update these terms from time to time; continued use of the service after changes constitutes acceptance of the revised terms.
PrepLion offers a free tier, a Pass subscription ($19/month or $149/year), and a Fast Track one-time plan ($49 for 90 days). All payments are processed securely by Stripe. PrepLion does not store your credit card number or payment details on our servers — this information is handled entirely by Stripe in accordance with PCI-DSS standards. Subscription charges renew automatically at the end of each billing period unless cancelled before the renewal date.
We offer a 7-day money-back guarantee on new Premium subscriptions. If you are not satisfied within 7 days of your first Premium payment, contact us at [email protected] and we will issue a full refund — no questions asked. After the 7-day window, subscription payments are non-refundable. You may cancel at any time and will retain Premium access through the end of your paid billing period.
You may cancel your Premium subscription at any time from the Billing page within your account. Cancellation takes effect at the end of the current billing period — you will not be charged again, and you will continue to have Premium access until that date. Cancellations do not entitle you to a prorated refund of any unused portion of the subscription period, except as described in our 7-day money-back guarantee above.
