Pricing, Billing & Payment Terms

1.1 Membership, Not Individual Courses. Cavua does not sell individual Courses, and authors do not set Course prices. Access to Courses and to the Platform's AI features is provided through membership plans. Each plan grants: a number of course slots, each of which holds one Course at a time; a number of Course previews; a number of video and voice AI tutor sessions of a stated length in each billing period; and usage allowances for AI chat, document uploads and storage, audio summaries, and other features. The current plans, and what each includes, are displayed on the Platform before you subscribe.

1.2 Free Plan. Cavua may offer a free plan with limited previews, trial tutor sessions, and allowances, and no course slots. No payment information is required for the free plan, and Cavua may change or withdraw it at any time.

1.3 Prices. All prices are stated in United States Dollars (USD) unless otherwise indicated. The total charge, and when it will be charged, is displayed before you confirm any payment. Cavua may offer temporary sale or promotional prices; when a sale ends, the regular price applies to new purchases.

1.4 Price Changes. Cavua may change the price of a plan or recurring add-on. A price change applies to an existing recurring subscription only from a billing period that begins at least thirty (30) days after Cavua notifies you by email or on the Platform. If you do not agree to the change, you may cancel before it takes effect. A price change never affects a payment already made.

2.1 Billing Period. Memberships are billed in advance for each billing period, which is monthly or, where offered, yearly. Your billing period begins on the date your first payment succeeds and renews on the same date each month or year.

2.2 Automatic Renewal. YOUR MEMBERSHIP RENEWS AUTOMATICALLY AT THE END OF EACH BILLING PERIOD UNTIL YOU CANCEL. BY SUBSCRIBING, YOU AUTHORIZE CAVUA, THROUGH ITS PAYMENT PROCESSOR, TO CHARGE YOUR PAYMENT METHOD ON FILE AT EACH RENEWAL FOR THE THEN-CURRENT PRICE OF YOUR PLAN AND ANY RECURRING ADD-ONS, PLUS ANY APPLICABLE TAXES.

2.3 Cancellation. You may cancel at any time from the Plans & billing section of your profile, or by contacting support@cavua.ai. Turning off automatic renewal has the same effect as cancelling. Cancellation takes effect at the end of your current billing period: you keep your plan, course slots, and allowances until then, and you may resume before the period ends. Cancellation does not entitle you to a refund for the current billing period (see the Refund Policy).

2.4 Gifted Memberships. Cavua may, at its discretion, gift a membership plan to a user. A gift covers the plan's own fee only. Course slot add-ons, session packs, and other purchases made on a gifted membership are charged at their regular price and require a payment method. Cavua may end a gifted membership at any time.

3.1 How Course Slots Work. Each course slot holds one Course at a time. Enrolling in a Course places it in an empty course slot. If all of your course slots are full, you may add course slots or wait for your next renewal.

3.2 The Slot Cycle. A course slot is filled for a billing period. Once a Course is in a course slot, it stays there until your next renewal date and cannot be released before then; an empty course slot may be filled at any time. Before each renewal you will be asked, for each Course, whether to keep it or release it for the next billing period. You may instead turn on automatic keeping for a Course, so that it stays in its course slot at every renewal without being asked. If you do not answer, your Courses stay where they are.

3.3 Additional Course Slots. You may add course slots to your membership as a recurring add-on, billed together with your plan in each billing period. When you add course slots, you are charged straight away a pro-rata amount for the rest of the current billing period, and the full add-on price at each renewal after that. When you remove course slots, the removal takes effect at your next renewal, with no refund or credit for the current billing period, and you may undo it before then. Each change is shown for your confirmation, with the amount charged today and the amount you will pay from your next billing date, before it is made.

3.4 Fewer Course Slots Than Courses. If your course slots fall below the number of Courses you hold, for example because you downgrade, remove course slots, or cancel, or because your membership ends or cannot be renewed, access to your Courses is paused until you choose which Courses to keep within your remaining course slots. Courses you do not keep are released from their course slots, and you may return them to a course slot later when one is free.

4.1 Upgrades. A change to a higher-priced plan takes effect immediately. You are charged a pro-rata amount for the rest of the current billing period, and the new plan's course slots and allowances apply straight away.

4.2 Downgrades. A change to a lower-priced plan takes effect at your next renewal. You keep your current plan until then and may undo the downgrade before your renewal date. Section 3.4 applies if the new plan has fewer course slots than the Courses you hold.

5.1 Included Sessions. Your plan includes a number of video and voice AI tutor sessions in each billing period, each up to a stated length. Included sessions reset at the start of each billing period and do not roll over.

5.2 Session Packs. You may buy additional video or voice sessions as a one-time purchase. Purchased session credits do not expire while your account remains open, remain available if you change or cancel your plan, have no cash value, and cannot be transferred.

5.3 How Sessions Are Used. Your plan's included sessions are always used before purchased session credits. A call may run up to the longest session length available to you, and what it uses is decided by its actual duration: the shortest available session that covers the call. A call that never connects uses nothing.

5.4 Session Upgrades. Where offered, you may lengthen session credits you already hold by paying for the additional minutes. Session upgrades are one-time purchases.

6.1 What Is Included. Plans include allowances for AI chat (including the book tutor, the Work workspace, research, and quizzes), document uploads (measured in pages processed) and storage, audio summaries, and other features, as displayed on the Platform. AI chat is measured over a five-hour window, which begins with your first message, and over a weekly window anchored to your renewal date, and both apply at once. Other allowances are measured per billing period or, on the free plan, per calendar month.

6.2 How Usage Is Counted. Chat usage is measured in weighted units that reflect the size of each request and answer, so longer or more complex requests use more of your allowance than short ones. The Platform shows how much of each allowance you have used and when it resets. Upload pages are counted when a document is processed and are not restored if you later delete the document.

6.3 Reaching a Limit. When you reach an allowance, the feature pauses until the allowance resets. You may upgrade your plan, or buy session packs where offered, to continue sooner. Allowances do not roll over, have no cash value, and are not refundable.

6.4 Changes to Allowances. Cavua may change the allowances included in a plan. A change that materially reduces an allowance of a paid plan you hold takes effect from your next billing period after notice to you.

7.1 Author AI Tutors. Where offered, you may unlock an author's AI tutor with a one-time payment. An unlock applies to all of that author's Courses and is non-refundable. Its availability may change, including if the author withdraws the tutor.

7.2 Previews. Course previews are counted over the life of your account and are not charged for.

8.1 All payments are processed by Stripe. By making a payment, you agree to Stripe's terms of service in addition to these Terms. Payments are made on Cavua's own checkout pages using Stripe's secure card fields, and only credit and debit cards supported by Stripe are accepted.

8.2 One Payment Method. The default card on your account pays for your membership, your recurring add-ons, and your other purchases. Making a different card your default moves all recurring charges to it. You cannot remove your default card while a paid membership is active.

8.3 Billing Details. The billing details you give at checkout, such as your name, email address, phone number, and billing address, are stored with Stripe so that future checkouts can be pre-filled.

8.4 Your bank or card issuer may apply currency conversion or foreign transaction fees for non-USD accounts; Cavua has no control over and accepts no liability for such charges.

Invoices and receipts for your payments are available in the billing section of your profile, and Cavua or Stripe may also send them to your registered email address.

10.1 If a payment fails at checkout (for example, because of insufficient funds, a card decline, or an authentication failure), no charge is made and nothing is granted. You may try again with the same or a different card.

10.2 If a renewal payment fails, Cavua's payment processor will retry it over a period of time, and you should update your card in your profile. While retries continue, your access may continue. If payment still cannot be collected, your membership may be suspended or cancelled, and Section 3.4 applies to your course slots. You authorize these retries.

You are responsible for all applicable taxes, levies, or duties imposed by your jurisdiction. Cavua will collect and remit taxes only where required to do so by applicable law. Where applicable tax is required to be collected, it will be displayed separately before you confirm your payment.

12.1 Referral commissions are amounts owed by Cavua to you under the Referral Program terms in the Student Terms of Service, not payments from you to Cavua.

12.2 Referral commissions are disbursed via Tipalti on a periodic schedule set by Cavua. To receive payouts, you must complete payee onboarding through the Tipalti portal, accessible from your profile. Payouts will not be processed for accounts with incomplete or unverified Tipalti payee status.

13.1 If you believe a charge on your account is incorrect, please contact support@cavua.ai before initiating a chargeback with your bank. We will investigate and respond within 5 business days.

13.2 Initiating a chargeback without first contacting Cavua support may result in immediate suspension of your account pending resolution. Where a chargeback is found to be unwarranted, Cavua reserves the right to recover the disputed amount through available legal channels.

Refund eligibility and process are governed by the Cavua Refund Policy, incorporated into these Billing Terms by reference and available at cavua.ai/legal/refund.
