Terms of Service

Effective Date: October 17, 2026

These Terms of Service ("Terms") govern your use of the Jubjub Korean mobile application (the "App") operated by We Are Somos ("Company", "we", "us", or "our"). By using the App, you agree to be bound by these Terms.

1. Eligibility

The App is intended for users aged 13 and older. By creating an account, you confirm that you are at least 13 years of age. If we discover that a user is under 13, we reserve the right to immediately terminate the account.

2. Services and Paid Subscriptions

(1) The Company provides the following services:
  a. Free access: all learning stages for 5 permanently free videos and 2 weekly free videos that rotate every week; a Stage 1 (full-video watching) preview for all other videos; and word learning within the free range.
  b. Paid subscription (Premium): all learning stages for every video, full word learning, unlimited saved sentences, and more.
(2) Weekly free videos are available only during the applicable week (Monday 00:00 through Sunday 24:00, Korea Standard Time), after which access ends. Starting a video during that week does not grant you the right to continue using it after the week ends.
(3) The following paid plans are offered:
  - Monthly plan: billed monthly, renews automatically
  - Annual plan: billed yearly, renews automatically
  - Lifetime plan: one-time payment, no renewal
(4) Subscription pricing and terms are disclosed in detail on the in-app purchase screen and the payment screen of Google Play or the Apple App Store.
(5) Auto-renewing plans renew automatically on the same terms unless cancelled at least 24 hours before the next billing date. You can cancel in the subscription management settings of the Apple App Store or Google Play. The Company cannot access your payment method or cancel a subscription on your behalf.

3. Free Trial

(1) The Company may offer a 7-day free trial for the annual plan.
(2) Unless you cancel at least 24 hours before the trial ends, the trial automatically converts to a paid subscription and you will be charged.
(3) The free trial is limited to one per user, and eligibility may be restricted under the app store's policies.
(4) If you cancel during the trial, you will not be charged and you may continue to use the App for the remainder of the trial period.

4. Lifetime Plan

(1) The Lifetime plan is a non-consumable product purchased with a one-time payment and does not renew automatically.
(2) "Lifetime" refers to the period during which the Company operates the App, not the lifetime of the purchaser.
(3) If the Company must discontinue the App for unavoidable reasons, we will give notice via in-app announcement or similar means at least 30 days before the discontinuation date and will stop selling new Lifetime plans as of that notice. Any remaining access will be handled in accordance with applicable law and app store policies.
(4) The Lifetime plan is tied to the purchasing account and may not be transferred to a third party.
(5) If you change devices or reinstall the App, you can regain access by using "Restore Purchases" in the App.

5. Cancellations and Refunds

(1) Cancellations and refunds for paid subscriptions purchased through the App are subject to applicable law and the refund policies of the Apple App Store and Google Play. The Company has no authority to directly refund purchases made through the app stores.
(2) Partial refunds for unused subscription periods are not automatically issued upon account deletion, so you must cancel your active subscription in your app store account before deleting your account.
(3) The Company may add, modify, or remove in-app content (videos and words) at any time, and changes to individual content items do not constitute grounds for a subscription refund.

6. Third-Party Content and Links

(1) Videos in the App are played through the YouTube embedded player, and YouTube may collect information during playback in accordance with its own policies. The Google Privacy Policy applies to the processing of that information.
(2) The Company is not responsible for any loss or damage resulting from your voluntary access to third-party links or content presented in the App.

7. User Accounts and Conduct

- You are solely responsible for maintaining the security of your account credentials (email and password).
- You agree not to impersonate others, infringe intellectual property rights, or engage in any abusive or fraudulent use of the App. Violations may result in account suspension or termination without prior notice.

8. Intellectual Property and Limitation of Liability

- All video content, learning materials, and other content available in the App are protected by copyright and belong to the original rights holders or the Company. You may not reproduce, distribute, or use any content from the App for commercial purposes without explicit written permission.
- The Company is not liable for service interruptions caused by force majeure events (e.g., natural disasters, network failures) or for service disruptions or data loss resulting from user error.

9. Changes to These Terms

(1) We reserve the right to modify these Terms at any time, within the limits permitted by applicable law.
(2) We will notify you of changes via in-app notice or email at least 7 days before they take effect, or at least 30 days before for changes that are unfavorable to users.
(3) If you do not agree to the updated Terms, you may delete your account. Continued use of the App after the effective date constitutes your acceptance of the changes.

10. Governing Law and Dispute Resolution

- These Terms are governed by and construed in accordance with the laws of the Republic of Korea.
- Any disputes arising in connection with these Terms shall first be resolved through good-faith negotiation between the parties. If unresolved, disputes shall be subject to the jurisdiction of the competent courts in the Republic of Korea.
- Nothing in these Terms limits your statutory rights as a consumer under the laws of your country of residence.
