Subscription Terms

These Subscription Terms govern payment, withdrawal of purchase, and refunds for the paid subscription services and paid items provided by AI Voca (the "Company"). Matters not covered here are governed by the Terms of Service.

1. Types of Paid Services

  1. "Subscription Service" means a time-limited paid service providing premium features such as AI word generation, removal of learning limits, and ad-free use for a fixed period.
  2. "Paid Items" means consumable goods (such as Feathers) purchased with a one-time payment inside the app.
  3. The type, contents, term, and price of each paid service are as displayed on the purchase screen in the app.

2. Payment and Value-Added Tax

  1. Payment for paid services is made only through the in-app purchase system of the app market from which you installed the app (Apple App Store or Google Play), and that app market bills you for the amount.
  2. All amounts displayed on the in-app purchase screens and in the app market include value-added tax (VAT). No amount other than the displayed price is charged to you.
  3. The display currency follows the country setting of your app market account. Displayed amounts may change due to exchange rate fluctuations or the app market's pricing policy.
  4. Once payment is complete, you can confirm the payment date and amount from the receipt issued by the app market.

3. Automatic Renewal

  1. Subscription Services are provided on an automatically renewing basis.
  2. Unless you cancel at least 24 hours before the end of the current period, the subscription renews on the same terms and the renewal amount is charged at the time of renewal.
  3. The renewal amount and renewal cycle can be checked on the in-app purchase screen and in your app market's subscription management screen.
  4. Where a free trial is offered, the subscription converts to a paid subscription and is charged unless you cancel at least 24 hours before the trial ends.

4. Cancelling a Subscription

  1. You may cancel your subscription at any time. Cancellation stops the next renewal charge.
  2. Cancellation methods:
    • In the app: Settings → Customer Support → Write inquiry → select "Payment cancellation / withdrawal" and request cancellation.
    • Directly in the app market: Apple App Store — Settings → Apple Account → Subscriptions / Google Play — Play Store → Profile → Payments and subscriptions → Subscriptions.
  3. After cancellation you may continue to use the service until the end of the period already paid for.
  4. Deleting the app alone does not cancel your subscription.

5. Withdrawal of Purchase

  1. You may request withdrawal of a purchase (cancellation) within 7 days from the date of payment for a paid service. The period starts on the date the payment was approved; where a subscription renews automatically, the period is recalculated from the date each renewal payment was approved.
  2. How to request withdrawal:
    • In the app: Settings → Customer Support → Write inquiry → select "Payment cancellation / withdrawal"
    • The "Payment cancellation & refund inquiry" button on the subscription screen and the Feather shop screen opens the same screen.
    • By email: the customer inquiry email address stated in Article 8.
  3. The Company reviews and processes a withdrawal request within 3 business days of receipt and informs you of the outcome through a reply to your in-app inquiry or by email.
  4. Because in-app purchases are billed and collected by the app market, the refund of the amount following a withdrawal is carried out through that app market's refund procedure. The Company submits and pursues the refund request with the app market on your behalf and keeps you informed of its progress and outcome.
  5. Withdrawal may be restricted in the following cases. The Company will inform you of the reason where this applies.
    • Where paid items (such as Feathers) have already been used. However, withdrawal remains available for any unused balance.
    • Where you have consumed a substantial part of content available only through a paid service, such that its value has significantly decreased.
    • Services provided free of charge, or goods granted through events.
  6. Where the goods or services differ from their description or advertising, or were performed differently from the contract, you may request withdrawal within 30 days of the date you became aware, or could have become aware, of that fact. The restrictions in paragraph 5 do not apply in that case.

6. Refunds

  1. Where a withdrawal under Article 5 takes effect, the Company refunds the full amount paid.
  2. For cancellation after the 7-day withdrawal period, the Company refunds the amount for the remaining term after deducting the amount corresponding to the period already used and a refund handling fee. No deduction is made for any period during which the service was unavailable due to the Company's fault.
  3. Refunds are made to the same payment method used for the purchase. For in-app purchases, the app market's refund processing procedure and timeframe apply.
  4. Where the service was suspended or not provided due to the Company's fault, the Company refunds the corresponding amount or extends the service period without requiring a request from you.
  5. No refund may be made where your use was restricted because you breached these Terms.

7. Changes to Subscription Policy

  1. The Company may change the contents, price, or subscription policy of paid services as required for the operation of the Service.
  2. The Company will announce the effective date and details of any change at least 7 days in advance (at least 30 days in advance for changes unfavourable to users) by in-app notice or email.
  3. Where a price increases, it applies to an ongoing subscription only from the point you consent to it. If you do not consent, you may cancel before renewal.

8. Inquiries and Dispute Resolution

  1. Inquiries about payment, withdrawal, or refunds can be submitted through Settings → Customer Support in the app, or to the contact details in the business information below.
  2. The Company promptly handles any opinion or complaint raised by a user where it is found to be justified.
  3. Where a dispute between the Company and a user is not resolved amicably, the user may apply for mediation to the Korea Consumer Agency, the Electronic Commerce Mediation Committee, or another relevant body.
